One frequently cited advantage of deploying GPS-monitored FOBs is that the position information can be used for directed fishing to reduce search time for tuna. However, purse seiners also fish on foreign objects for which position information is not available. It is critical to quantify the prevalence of fishing on GPS-monitored versus unmonitored FOBS in order to understand how they impact fishing effort and catch per unit effort (CPUE). We analyzed French commercial, observer, and FOB trajectory data in the Atlantic and Indian oceans to determine how often purse seine vessels fish on GPS-monitored FOBs. Only 2.7-20.4% of French FOB fishing sets over 2007-2013 in both oceans were made on GPS-monitored FOBs. Though increasing over time, the low percentage suggests that French vessels do not primarily use GPS-monitored FOBs to reduce search time for tuna.

If hyperstability is not detected, it can lead to overly positive assessments of stock status, threatening fisheries sustainability. Though there is no evidence that this is occurring in the tropical tuna purse-seine fisheries of the Atlantic and Indian Oceans, it is useful to complement more sophisticated stock status estimations with simpler approaches based on analyses of raw catch-effort data. Here we present analyses of the spatial distribution of catch and effort for the European tropical tuna purse-seine fisheries of the Atlantic and Indian Oceans. We develop a series of annual spatial indices for the catch of the three major species of tropical tunas, skipjack tuna, bigeye tuna and yellowfin tuna, as a function of ocean and fishing mode (floating object or free swimming fish schools). Time series of these indices are examined to identify temporal trends and/or unique events with a particular eye towards any long term trends that might be indicative of declining stock status and hyperstability in stock status estimates. Similar spatial indices are also calculated for important bycatch species from observer data for French purse-seine vessels. In general, results indicate a relative stability in the spatial distribution of catch over the last 30 years, though major perturbations to the fisheries, such as due to Somali piracy and major El Niño events, are identifiable. Nevertheless, recent decreasing trends in the presence of bigeye tuna and certain bycatch species in the Indian Ocean merit further investigation.", "reportNumber": "IOTC-2021-WPTT23-20_Rev1", "reportType": "", "institution": "IOTC Working Party on Tropical Tuna (WPTT23)", "place": "", "date": "10/2021", "seriesTitle": "", "seriesNumber": "", "pages": "29", "DOI": "", "ISBN": "", "citationKey": "", "url": "https://www.iotc.org/documents/WPTT/2302/20", "accessDate": "2021-12-17", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English (US)", "libraryCatalog": "", "callNumber": "", "rights": "All rights reserved", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2021-12-17T10:00:11Z", "dateModified": "2021-12-17T10:00:11Z" } }, { "key": "9W5MJFTC", "version": 9259, "library": { "type": "group", "id": 5393, "name": "David Michael Kaplan's publications", "links": { "alternate": { "href": "https://www.zotero.org/groups/david_michael_kaplans_publications", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/5393/items/9W5MJFTC", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/david_michael_kaplans_publications/items/9W5MJFTC", "type": "text/html" } }, "meta": { "createdByUser": { "id": 3449, "username": "dmk", "name": "David M.

Here, we analyzed approximately 40,000 dFAD trajectories in the Indian Ocean and 12,000 dFAD trajectories in the Atlantic Ocean deployed over the decade 2008–2017 to identify where and when beachings occur. We find that there is tremendous promise for reducing beaching events by prohibiting deployments in areas most likely to lead to a beaching. For example, our results indicate that 21% to 40% (depending on effort redistribution after closure) of beachings can be prevented if deployments are prohibited in areas in the south of 8°S latitude, the Somali zone in winter, and the western Maldives in summer for the Indian Ocean, and in an elongated strip of areas adjacent to the western African coast for the Atlantic Ocean. In both oceans, the riskiest areas for beaching are not coincident with areas of high dFAD deployment activity, suggesting that these closures could be implemented with relatively minimal impact to fisheries. Furthermore, the existence of clear hotspots for beaching likelihood and the high rates of putative recovery of dFAD buoys by small-scale fishers in some areas suggests that early warning systems and dFAD recovery programs may be effective in areas that cannot be protected via closures if appropriate incentives can be provided to local partners for participating in these programs.", "publicationTitle": "Biological Conservation", "publisher": "", "place": "", "date": "February 1, 2021", "volume": "254", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "108939", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Biological Conservation", "DOI": "10.1016/j.biocon.2020.108939", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0006320720309976", "accessDate": "2021-01-12T14:14:11Z", "PMID": "", "PMCID": "", "ISSN": "0006-3207", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "All rights reserved", "extra": "tex.ids: ImzilenSpatialmanagementcanaccepted", "tags": [ { "tag": "Coral reefs", "type": 1 }, { "tag": "Fish aggregating device (FAD)", "type": 1 }, { "tag": "Fishing debris", "type": 1 }, { "tag": "Marine pollution", "type": 1 }, { "tag": "Ocean currents", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2021-12-17T10:00:11Z", "dateModified": "2021-12-17T10:00:11Z" } }, { "key": "6H6YEA5B", "version": 9259, "library": { "type": "group", "id": 5393, "name": "David Michael Kaplan's publications", "links": { "alternate": { "href": "https://www.zotero.org/groups/david_michael_kaplans_publications", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/5393/items/6H6YEA5B", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/david_michael_kaplans_publications/items/6H6YEA5B", "type": "text/html" } }, "meta": { "createdByUser": { "id": 3449, "username": "dmk", "name": "David M.

Stochastic Frontier Analysis (SFA) and Data Envelopment Analysis (DEA) were used to define environmentally-determined production frontiers, i.e. production possibilities based on empirical observations of aquaculture production, available space, and environmental conditions. Both methods estimated Lease Capacity Utilization (LCU, from 0 to 1) for leases producing oysters with intensive culture methods from 2007 to 2016. Models revealed significant heterogeneity in lease utilization and mean LCU scores of 0.25 (DEA) and 0.27 (SFA), which suggests many leases could scale up production or reduce the size of their lease to more efficiently utilize ambient environmental conditions (i.e., achieve scores closer to 1). Capacity underutilization arising from characteristics of the leaseholder and surrounding spatial environment were quantified and indicated efficiency gains for horizontally integrated leaseholders, though also suggested leases in more populated areas were less efficiently used, possibly due to increased use conflicts.

Understanding the effects of this new technology on catch of the three main tuna species (yellowfin tuna, Thunnus albacares; bigeye tuna, Thunnus obesus; and skipjack tuna, Katsuwonus pelamis) is important to accurately correct for this change in catch-per-unit-effort (CPUE) indices used for stock assessments. We analysed catch data from the French purse seine fleet for the period 2010–2017 in the Indian Ocean to assess the impact of this fleet’s switch to echosounder buoys around 2012. Results indicate that echosounders do not increase the probability a set will be succesful, but they have a positive effect on catch per set, with catches on average increasing by ≈2−2.5 tonnes per set (≈10%) when made on the vessel's own dFADs equipped with an echosounder buoy. Increases were due to a decrease in sets below ≈25 tonnes and an increase in those greater than ≈25 tonnes, with a non-linear transition around this threshold.

Key to improving the effectiveness of MPAs, and ensuring that they achieve desired outcomes, will be better monitoring that includes ecological and social data collected inside and outside of MPAs. This can lead to more conclusive evidence about what is working, what is not, and why. Eight authors were asked to write about their experiences with MPA effectiveness. The authors were instructed to clearly define “effectiveness” and discuss the degree to which they felt MPAs had achieved or failed to be effective. Essays were exchanged among authors and each was invited to write a shorter “counterpoint.” The exercise shows that, while experiences are diverse, many authors found common ground regarding the role of MPAs in achieving conservation targets.

However, their limited coverage leads to important data gaps that preclude bycatch mitigation at the basin scale. Habitat models developed from available fisheries observer programs offer a potential solution to fill these gaps. We focus on tropical tuna purse seine fisheries (TTPSF) that span across the tropics and extensively rely on floating objects (FOBs) for catching tuna schools, leading to the bycatch of other species associated with these objects. Bycatch under floating objects is dominated by five species, including the vulnerable silky shark Carcharhinus falciformis and four bony fishes (oceanic triggerfish Canthidermis maculata, rainbow runner Elagatis bipinnulata, wahoo Acanthocybium solandri, and dolphinfish Coryphaena hippurus). Our objective was to predict possible bycatch hotspots associated with FOBs for these five species across two tropical oceans. We used bycatch data collected from observer programs onboard purse seiners in the Atlantic and Indian oceans. We developed a generalized additive model per species and per ocean relating bycatch to a set of environmental covariates (depth, chlorophyll-a concentration, sea surface temperature, mixed layer depth, surface salinity, total kinetic energy and the density of floating objects) and temporal covariates (year and month). We extrapolated modeled relationships across each ocean within the range of environmental covariates associated with the bycatch data and derived quarterly predictions. We then detected bycatch hotspots as the 90th percentiles of predictions. In the Atlantic Ocean, bycatch hotspots were predicted throughout tropical and subtropical waters with little overlap between species. By contrast in the Indian Ocean, major overlapping hotspots were predicted in the Arabian Sea throughout most of the year for four species, including the silky shark. Our modeling approach provides a new analytical way to fill data gaps in fisheries bycatch.

We find that there is tremendous promise for reducing beaching events by prohibiting deployments in areas most likely to lead to a beaching. For example, our results indicate that around 40% of beachings can be prevented if deployments are prohibited in areas in the south of 8°S latitude, the Somali zone in winter, and the western Maldives in summer for the IO, and in an elongated strip of areas adjacent to the western African coast for the AO. In both oceans, the riskiest areas for beaching are not coincident with areas of high dFAD deployment activity, suggesting that these closures could be implemented with relatively minimal impact to fisheries. Furthermore, the existence of clear hotspots for beaching likelihood and the high rates of putative recovery of dFAD buoys by small-scale fishers in some areas suggests that early warning systems and dFAD recovery programs may be effective in areas that cannot be protected via closures if appropriate incentives can be provided to local partners for participating in these programs.", "publicationTitle": "bioRxiv", "publisher": "", "place": "", "date": "2020-11-05", "volume": "", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "2020.11.03.366591", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1101/2020.11.03.366591", "citationKey": "", "url": "https://www.biorxiv.org/content/10.1101/2020.11.03.366591v1", "accessDate": "2020-11-06T07:45:01Z", "PMID": "", "PMCID": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "www.biorxiv.org", "callNumber": "", "rights": "© 2020, Posted by Cold Spring Harbor Laboratory.

This network provides a rare opportunity to examine spatial and temporal trends in TURF use and impacts on surrounding open access areas (OAAs). In this analysis, landings of keyhole limpet (Fissurella spp.), kelp (Lessonia spp.) and red sea urchin (Loxechinus albus) were used to estimate catch-per-unit effort (CPUEs) and catch-per-unit area (CPUAs) indices inside and outside TURFs by fishing cove. For these species, CPUEs and CPUAs in 2015 were significantly higher inside TURFs. However, temporal trends analyzed with a linear mixed effects model indicate that CPUAs inside TURFs have been significantly decreasing since 2000 for keyhole limpet, red sea urchin and for loco (Concholepas concholepas), while in OAAs this measure only decreased for limpet. An elastic net regression was used to better explain catches in OAAs during 2015, including a variety of variables related to the characteristics and activity of proximal TURFs. Results indicate that exogenous factors unrelated to TURF management were the primary drivers of catches in OAAs during 2015 but that factors related to proximal TURFs appear to have a slight negative impact that grows over time. Collectively, these results indicate that while TURFs are associated with higher catch rates than surrounding OAAs, catch rates appear to be decreasing over time and, though limited, the impact of TURFs on surrounding OAAs may be negative.

In many areas, recovery of oyster aquaculture faces significant societal opposition and spatial constraints limiting its ability to meet expectations regarding future food needs and provision of ecosystem services. In Virginia, oyster aquaculture has begun to rebound, concurrent with an increase in subaqueous leased areas (over 130,000 acres of grounds are currently leased). Though private leases must in theory be used for oyster production, in practice, they can be held for other reasons, such as speculation or intentional exclusion of others. These factors have led to large variation over time and space in the use of leases in the lower Chesapeake Bay, and privately leased grounds are now thought to be underutilized for oyster production. This research examined potential barriers to expansion of oyster aquaculture in Virginia. We first evaluated if a lack of space was limiting industry expansion and quantified temporal and spatial trends in the use and productivity of leases. Then, differences in used and non-used leases were investigated in relation to variables thought to be related to “not in my backyard” attitudes, congestion, speculation, local economic and environmental conditions. Finally, the performance of the Virginia leasing system was compared with those in other states along the U.S. East and Gulf Coasts. We found limited evidence of spatial constraints though strong evidence of social and regulatory inefficiencies. While rates of lease use increased from 2006 to 2016, only 33% of leases were ever used for oyster production and about 63% of leaseholders reported no commercial harvests. Non-used leases tended to be smaller, and were found in more populated, high-income regions, consistent with both speculative and exclusionary uses. Virginia was found to have the lowest levels of total production of cultured oysters per leased acre among the states of the eastern U.S. These results indicate that there is room for oyster aquaculture expansion in Virginia if societal, regulatory and economic barriers can be reduced or if existing leased areas are used more efficiently.", "publicationTitle": "Frontiers in Marine Science", "publisher": "", "place": "", "date": "2020", "volume": "7", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "53", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Front.

(2018) used a virtual species approach to test the effects of outliers on species distribution models. In their simulations, they applied a threshold value over the simulated suitabilities to generate the species distributions, suggesting that using a probabilistic simulation approach would have been more complex and yield the same results. Here, we argue that using a probabilistic approach is not necessarily more complex and may significantly change results. Although the threshold approach may be justified under limited circumstances, the probabilistic approach has multiple advantages.

We applied this model to 2009–2014 stranding events within the Chesapeake Bay, Virginia. Predicted origin of vessel strike strandings were compared to commercial vessel data, and potential hazardous turtle-vessel interactions were identified in the southeastern Bay and James River. Commercial fishing activity of gear types with known sea turtle interactions were compared to predicted mortality locations for stranded turtles with suggested fisheries-induced mortality. Probable mortality locations for these strandings varied seasonally, with two distinct areas in the southwest and southeast portions of the lower Bay. Spatial overlap was noted between potential mortality locations and gillnet, seine, pot, and pound net fisheries, providing important information for focusing future research on mitigating conflict between sea turtles and human activities. Our ability to quantitatively assess spatial and temporal overlap between sea turtle mortality and human uses of the habitat were hindered by the low resolution of human use datasets, especially those for recreational vessel and commercial fishing gear distributions.

We used empirical sea turtle carcass decomposition and drift experiments in the Chesapeake Bay, Virginia, USA to estimate probable carcass oceanic drift times and quantify the impact of direct wind forcing on carcass drift. Based on the time period during which free-floating turtle carcasses tethered nearshore were buoyant, we determined that oceanic drift duration of turtle carcasses was highly dependent on water temperature and varied from 2 to 15 days during typical late spring to early fall Bay water conditions. The importance of direct wind forcing for turtle carcass drift was assessed based on track divergence rates from multiple simultaneous deployments of three types of surface drifters: bucket drifters, artificial turtles and turtle carcass drifters. Turtle drift along-wind leeway was found to vary from 1 to 4% of wind speed, representing an added drift velocity of approximately 0.03–0.1 m/s for typical Bay wind conditions. This is comparable to current speeds in the Bay (0.1–0.2 m/s), suggesting wind is important for carcass drift. Estimated carcass drift parameters were integrated into a Chesapeake Bay oceanographic drift model to predict carcass drift to terrestrial stranding locations. Increased drift duration (e.g., due to low temperatures) increases mean distance between expected mortality events and stranding locations, as well as decreases overall likelihood of retention in the Bay. Probable mortality hotspots for the peak month of strandings (June) were identified off coastal southeastern Virginia and within the lower Bay, including the Bay mouth and lower James River. Overall, results support that sea turtle drift time is quite variable, and varies greatly depending on water and air temperature as well as oceanic conditions.

A dataset containing potentially relevant socioeconomic, environmental, and fisheries factors was assembled and used to model prefecture-level counts of marine protected areas (MPAs) and territorial use rights for fisheries (TURFs) throughout Japan's waters. Several factors were found to significantly influence the number of TURFs in a particular area, whereas MPA patterns of use remain largely unexplained. TURFs are frequently noted as more suitable for managing fisheries of low mobility species and our analysis finds greater use of TURFs in areas that rely heavily on benthic catch. The number of trading ports was also found to be positively related to TURF distributions, suggesting economic infrastructure may influence the use of this fisheries management tool. In-line with global analyses, MPA patterns of use were not found to be significantly related to any of the potential explanatory variables after correcting for the number of statistical comparisons that were carried out.

We review potential uncertainty sources in empirical larval connectivity studies and develop Bayesian statistical methods for estimating these uncertainties based on standard techniques in the mark-recapture and genetics literature. These methods are implemented in an existing R package for working with connectivity data, ConnMatTools, and applied to a number of published connectivity estimates. We find that the small sample size of collected settlers at destination sites is a dominant source of uncertainty in connectivity estimates in many published results. For example, widths of 95% CIs for relative connectivity, the value of which is necessarily between 0 and 1, exceeded 0.5 for many published connectivity results, complicating using individual results to conclude that marine populations are relatively closed or open. This “small sample size” uncertainty is significant even for studies with near-exhaustive sampling of spawners and settlers. Though largely ignored in the literature, the magnitude of this uncertainty is straightforward to assess. Better accountability of this and other uncertainties is needed in the future so that marine larval connectivity studies can fulfill their promises of providing important ecological insights and informing management questions (e.g. related to marine protected area network design, and stock structure of exploited organisms).

It came close to extinction after nearly a millennium of exploitation and currently persists as a population of only approximately 500 individuals. Setting appropriate conservation targets for this species requires an understanding of its historical population size, as a baseline for measuring levels of depletion and progress toward recovery. This is made difficult by the scarcity of records over this species’ long whaling history. We sought to estimate the preexploitation population size of the North Atlantic right whale and understand how this species was distributed across its range. We used a spatially explicit data set on historical catches of North Pacific right whales (NPRWs) (Eubalaena japonica) to model the relationship between right whale relative density and the environment during the summer feeding season. Assuming the 2 right whale species select similar environments, we projected this model to the North Atlantic to predict how the relative abundance of NARWs varied across their range. We calibrated these relative abundances with estimates of the NPRW total prewhaling population size to obtain high and low estimates for the overall NARW population size prior to exploitation. The model predicted 9,075–21,328 right whales in the North Atlantic. The current NARW population is thus <6% of the historical North Atlantic carrying capacity and has enormous potential for recovery. According to the model, in June–September NARWs concentrated in 2 main feeding areas: east of the Grand Banks of Newfoundland and in the Norwegian Sea. These 2 areas may become important in the future as feeding grounds and may already be used more regularly by this endangered species than is thought.", "publicationTitle": "Conservation Biology", "publisher": "", "place": "", "date": "March 1, 2016", "volume": "30", "issue": "4", "section": "", "partNumber": "", "partTitle": "", "pages": "783-791", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Conservation Biology", "DOI": "10.1111/cobi.12664", "citationKey": "", "url": "http://onlinelibrary.wiley.com/doi/10.1111/cobi.12664/abstract", "accessDate": "2016-06-08T16:20:37Z", "PMID": "", "PMCID": "", "ISSN": "1523-1739", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "Wiley Online Library", "callNumber": "", "rights": "© 2015 Society for Conservation Biology", "extra": "", "tags": [ { "tag": "Eubalaena", "type": 1 }, { "tag": "Population size", "type": 1 }, { "tag": "caza de ballenas", "type": 1 }, { "tag": "feeding grounds", "type": 1 }, { "tag": "generalized additive modeling", "type": 1 }, { "tag": "historical baseline", "type": 1 }, { "tag": "línea base histórica", "type": 1 }, { "tag": "modelado aditivo generalizado", "type": 1 }, { "tag": "tamaño de población", "type": 1 }, { "tag": "whaling", "type": 1 }, { "tag": "áreas de alimentación", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2018-01-19T13:47:27Z", "dateModified": "2018-01-19T13:47:27Z" } }, { "key": "3KR3WNTF", "version": 9257, "library": { "type": "group", "id": 5393, "name": "David Michael Kaplan's publications", "links": { "alternate": { "href": "https://www.zotero.org/groups/david_michael_kaplans_publications", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/5393/items/3KR3WNTF", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/david_michael_kaplans_publications/items/3KR3WNTF", "type": "text/html" } }, "meta": { "createdByUser": { "id": 3449, "username": "dmk", "name": "David M.

Fishing activity, in turn, is determined by the interaction of fish availability, fishing capacity, fishing costs and global markets for tuna products. In the face of overfishing, the continued sustainable supply of tuna is likely to require improved global governance, that would benefit from modeling frameworks capable of integrating market forces with the availability of fish in order to consider alternative future projections. Here we describe such a modeling framework, in which we develop several simple, contrasting scenarios for the development of the tuna supply chain in order to illustrate the utility of the approach for global evaluation of management strategies for tuna and other complex, stock-structured fisheries. The model includes multiple national and multi-national fishing fleets, canneries and fresh/frozen markets, and connects these to global consumers using a network of flows. The model is calibrated using recent data on fish catch, cannery and fresh/frozen production, and consumption. Scenarios explore the control on future outcomes in the global tuna fishery by representing, in a simple way, the effects of (1) climate change, (2) changes in the global demand for tuna, and (3) changes in the access to fishing grounds (marine reserves). The results emphasize the potential importance of increasing demand in provoking a global collapse, and suggest that controlling tuna production by limiting technical efficiency is a potential countermeasure. Finally we discuss the outcomes in terms of potential extensions of the scenario approach allowed by this global network model of the tuna supply chain.", "publicationTitle": "Deep Sea Research Part II: Topical Studies in Oceanography", "publisher": "", "place": "", "date": "June 1, 2017", "volume": "140", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "251-267", "series": "Future of oceanic animals in a changing ocean", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Deep Sea Research Part II: Topical Studies in Oceanography", "DOI": "10.1016/j.dsr2.2016.08.004", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0967064516302235", "accessDate": "2017-08-08T10:11:31Z", "PMID": "", "PMCID": "", "ISSN": "0967-0645", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "All rights reserved", "extra": "", "tags": [ { "tag": "Global supply chain", "type": 1 }, { "tag": "Scenarios", "type": 1 }, { "tag": "Tuna", "type": 1 }, { "tag": "climate change", "type": 1 }, { "tag": "marine protected area", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2018-01-19T13:47:27Z", "dateModified": "2018-01-19T13:47:27Z" } }, { "key": "G425ULYA", "version": 9257, "library": { "type": "group", "id": 5393, "name": "David Michael Kaplan's publications", "links": { "alternate": { "href": "https://www.zotero.org/groups/david_michael_kaplans_publications", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/5393/items/G425ULYA", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/david_michael_kaplans_publications/items/G425ULYA", "type": "text/html" } }, "meta": { "createdByUser": { "id": 3449, "username": "dmk", "name": "David M.

KAPLAN\n3\n, Nicolas BEZ\n2\n and Emmanuel CHASSOT\n4\nAbstract \nSince the mid 1990s, the use of drifting Fish Aggregating Devices (dFADs) by purse seiners, \nartificial objects specifically designed to aggregate fish, has become an important mean of \ncatching tropical tunas. In recent years, the massive deployments of dFADs, as well as the \nmassive use of tracking devices on dFADs and natural floating objects, such as GPS buoys, \nhave raised serious concerns for tropical tuna stocks, bycatch species and pelagic \necosystem functioning. Despite these concerns, relatively little is known about the modalities \nof dFAD use, \nmaking it difficult to assess and manage the impacts of this fishing practice. \nThe present paper provides an overview of a 4\n-year research on the use of dFADs by \ntropical tuna purse seiners in the W estern Indian \nOcean. Though our \nprimary objective was \nto derive information on dFAD fisheries from a large variety of quantitative sources of \ninformation (GPS buoy positions, onboard observers, logbooks and VMS), a multi\n-\ndisciplinary approach was adopted throughout our \nresearch. Quantitative results (estimates \nof dFAD use, fishing efficiency and impacts of dFAD use) were discussed with French purse \nseine skippers during semi\n-structured interviews to understand their perception of the \nimpacts of dFAD use and \nto propose ad\napted management options for tropical tuna purse \nseine dFAD fisheries\n. Interviews with French purse seine skippers revealed the existence of \na competition between EU purse seine fleets, encouraging the recent increase in the use of \ndFADs. They underlined t\nhe need for a more efficient management of the fishery, including \nthe implementation of catch quotas, a limitation of the capacity of purse seine fleets and a \nregulation of the use of support vessels \n\nIntegrating scientific and French tropical tuna purse seine skippers knowledge for a better management of dFAD fisheries in the Indian Ocean.

Lower transport success and higher dispersal distances are observed including larval vertical migration in the model. We find an overall decrease in larval transport success to settlement areas from northern to southern Chile.
