Book excerpt: This report on the Bering Sea/Aleutian Islands yellowfin sole trawl fishery is one of a six part series of reports summarizing catch perunit effort (CP[JE) and bycatch data extracted from the National Marine Fisheries Service Observer Program North Pacifìc (NORPAC) database. Other reports cover the other flatfìsh (including rock sole), pollock (bottom), pollock (midwater), Pacific cod, and miscellaneous individual skippers and vessel owners maintain their bycatch rates for prohibited species (halibut, herring, red king crab, and bairdi Tanner crab) within guidelines established by the North Pacific Fishery Management Council. Data from the period 1981 - 1989 are summarized by month, year, and geographic location (one-half-by-one-degree latituddlongitude blocls). Five l2-month series of charts are presented, each of which shows the Bering Sea/Aleutian Islands region divided into one-half-by-one degree latituddlongitude blocks on which bar graphs illustrating average CPUEs or bycatch rates are superimposed. These chart series provide a visual overview of the data through time and space. Other sections list the actual numerical data associated with each bar graph and provide tables summarizing the data by month and year. Tables listing the Month/Block/Yearr records wÍth the highest CPUEs and bycatch rates also are provided.

Available in PDF, EPUB and Kindle. Book excerpt: This publication gives an updated review of the quantity of discards in the world's marine fisheries, using information from a broad range of fisheries in all continents. A number of policy issues are discussed including a 'no discards' approach to fisheries management, the need for balance between bycatch reduction and bycatch utilisation initiatives, and concerns arising from incidental catches of marine mammals, birds and reptiles. The report also highlights the need for more robust methods of estimating discards, and the development of bycatch management plans.
Download or read book The Analytic Component to the Standardized Bycatch Reporting Methodology Omnibus Amendment written by Susan E. Wigley and published by . This book was released on 2007 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Standardized Bycatch Reporting Methodology (SBRM) can be viewed as the combination of sampling design, data collection procedures, and analyses used to estimate bycatch in multiple fisheries. The SBRM provides a structured approach for evaluating the efficacy of the allocation of observer days to multiple fisheries to monitor a large number of species under the different Fishery Management Plans (FMPs), the Marine Mammal Protection Act, and the Endangered Species Act. In this report, we examine 45 fleets and 60 species/species groups to encompass all federal FMP-managed species in the Northeast. A comprehensive summarization of 2004 data collected by the Northeast Fisheries Observer Program (NEFOP) is presented, as well as estimation of precision of bycatch for fish, turtles, marine mammals, and sea birds by using three methods and two discard ratios, an evaluation of these different methods, and the estimation of sea days required to achieve the desired level of precision. A combined ratio method using a discard-to-kept weight ratio was selected to evaluate the monitoring of bycatch over a diverse range of species and fleets in the Northeast region. We recognize that research on discard estimation is ongoing and future work may lead to improvements of this method. The number of sea days necessary to achieve a 30% coefficient of variation (CV) for all identified fisheries exceeds 33,000 days. Application of additional criteria for evaluating the efficacy of the monitoring program may lead to reductions in the total number of days necessary. In particular, criteria related to the magnitude of total discards relative to landings may reduce the number of days necessary to estimate infrequent discard events of fish"--Executive summary.
Download or read book A Guide to Bycatch Reduction in Tropical Shrimp trawl Fisheries written by Steve Eayrs and published by Food & Agriculture Org.. This book was released on 2007 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bycatch is the unwanted or non-target part of the catch taken by fishermen. It is either discarded at sea or used for human or animal consumption. The capture of bycatch may pose a threat to species diversity and ecosystem health because this part of the catch is usually unregulated. In tropical shrimp-trawl fisheries, bycatch often consists of juvenile food-fish species and is therefore a threat to food security and sustainable fisheries production. Bycatch is a global problem that must be addressed. This Guide to Bycatch Reduction in Tropical Shrimp-Trawl Fisheries is designed for fishermen, net makers, fishing technologists and others interested in a practical guide to the design, use and operation of effective bycatch reduction devices. Fishery managers, policy-makers and legislators will find this guide useful to help develop specifications governing the design and application of these devices in a shrimptrawl fishery. The issue of bycatch is not going away and scrutiny of fishing activity is increasing. All fishermen are strongly urged to use appropriate bycatch reduction measures to help maintain the productivity of the fishery and the long term prosperity of the fishing industry. By responding appropriately, fishermen can help to protect the marine environment and assist global food security both now and in the future. Also published in French and Spanish.

Available in PDF, EPUB and Kindle. Book excerpt: Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

Download or read book Allocating Observer Sea Days to Bottom Trawl and Gillnet Fisheries in the Northeast and Mid Atlantic Regions to Monitor and Estimate Incidental Bycatch of Marine Mammals written by Marjorie C. Rossman and published by . This book was released on 2007 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Estimating marine mammal bycatch mortality with low levels of uncertainty is important in attaining the conservation goals of the Marine Mammal Protection Act. The Protected Species Branch at the Northeast Fisheries Science Center allocates fishery observer sea days to achieve a 30% precision on estimates of incidental marine mammal bycatch in US gillnet and bottom trawl fisheries conducted off the Atlantic coast of the United States. A three-step process is used to: (1) project sample sizes; (2) proportionally allocate projected sea days to fishery strata; and (3) assign allocated sea days to ports and months within strata proportional to fishing effort. Under conditions of limited observer funding, a set of decision rules is followed to establish which fisheries will receive observer coverage. The amount of observer coverage (in sea days) needed to achieve a 30% precision in the bycatch estimates varies widely among fishery strata. In the 2007 fiscal year (October 2006 - September 2007), funding was only available for 802 observer sea days, although nearly 57,000 sea days are required provide a 30% precision in the bycatch estimates of harbor porpoise (Phocoena phocoena) and bottlenose dolphin (Tursiops truncatus) in the Northeast and Mid-Atlantic gillnet fisheries, and for pilot whales (Globicephala spp.), white-sided dolphin (Lagenorhynchus acutus), and common dolphin (Delphinus delphis) in the Northeast and Mid-Atlantic bottom trawl fisheries. After the decision rules were applied in FY07, all 802 observer sea days were allocated to coverage of the gillnet fisheries; 47% (377 days) was allotted to the Northeast gillnet fishery and 53% (425 days) to the Mid-Atlantic gillnet fishery. Due to the very large amount of fishing effort in the Northeast and Mid-Atlantic bottom trawl fisheries, a substantial increase in annual sampling coverage is required for monitoring what are essentially rare marine mammal bycatch events in these fisheries"--Abstract.
