Book excerpt: "This report describes the discard estimation analysis performed for Greater Atlantic Region fish and invertebrates for the forthcoming National Bycatch Report First Edition Update 3. Estimates of discards that occurred during the 2014 and 2015 calendar years in federally managed fisheries in the northeast United States were derived for 165 individual species and groups of finfish and invertebrates by using a combined discard/kept ratio estimator. Based on this analysis, approximately 101,356 mt (live weight) of discards occurred in 34 fleets in 2014, and approximately 99,542 mt (live weight) of discards occurred in 35 fleets in 2015 across the 165 individual species and groups considered. In both years, the predominant species discarded were (1) skates (Rajidae), (2) benthic species, other, and (3) American lobster (Homarus americanus). Sand dollars (Echinarachnius parma) was the driving species in the “Benthic Species, Other” group, contributing approximately 89% of the group’s total discards in 2014 and approximately 88% of the group’s total discards in 2015. Of the 2014 and 2015 discards, approximately 60,077 mt and 64,621 mt of discards occurred respectively for the 34 fish and invertebrate species with fishery management plans developed by the Mid-Atlantic Fishery Management Council and the New England Fishery Management Council in the waters off the northeastern United States. The discards reported in this document may not necessarily correspond directly with the discard estimates derived for individual stock assessments because of differences in stratification, data, and estimation methods. Hence, the discard estimates presented here are not definitive but indicative of where discarding is occurring among commercial fisheries and for which species"--Executive Summary.

This book was released on 2008 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: "NOAA Fisheries is currently preparing a National Bycatch Report summarizing estimates of discards, by species, which occurred in 2005 in all federally managed fisheries in the United States. This document briefly describes the methods used to estimate the discards of finfish and shellfish in 2005 in fisheries in the Northeast Region, which will be included in the National Bycatch Report. The regional analysis involved 33 species and 77 fleets. Stock components were not considered in the analyses, and only fleets for which discard estimates could actually be derived will be included in the National Bycatch Report. The discard estimation process used a stratification approach broad enough to encompass all species, and employed a combined ratio method using a discard-to-kept weight ratio. The discard estimates derived will not necessarily directly correspond with those contained in individual stock assessments due to differences in stratification and estimation methods. However, the various estimates should be of the same order of magnitude"--Introduction.

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.

Book excerpt: "This report describes the analyses associated with the discard estimation of 14 federally managed fish and invertebrate species groups during the July 2014 through June 2015 time period and the expected coverage needed by at-sea observers for northeastern US fisheries for the April 2016 through March 2017 period using the Standardized Bycatch Reporting Methodology. An estimated 57,063 mt (125,803,405 lb) of federally regulated species were discarded during the July 2014 through June 2015 time period. The predominant species groups discarded were skates (Rajidae) and spiny dogfish (Squalus acanthias). Across all species groups examined, "No Market" was the reason reported for the majority of discards. Analyses also revealed that for fleets with observer coverage, the coverage within a fleet corresponded with the spatial and temporal patterns of fishing activity in terms of kept weight of all species. The discards reported in this document may not necessarily correspond directly with the discard estimates derived for individual stock assessments because of differences in stratification and data. Hence, the discard estimates are not definitive, but indicative of where discarding occurred among commercial fleets and for which species groups. The sea days needed to achieve a precision-based performance standard (30% coefficient of variation of the discard estimate) were estimated to be 10,746 sea days for the 14 fish and invertebrate species groups across 57 fleets. The sea day analyses used a standardized protocol to account for the importance of the discarded species relative to the amount of discards by each fleet and total fishing mortality"--Executive Summary.

Book excerpt: "The National Bycatch Report provides the first national compilation of bycatch estimates for living marine resources of the United States that are managed by NOAA's National Marine Fisheries Service (NMFS). The NMFS has prepared this report to evaluate the extent to which reliable quantitative bycatch information exists for federally managed commercial fisheries and fisheries with relevant Federal data-collection programs. The report also documents bycatch estimates and bycatch estimation methods for all fisheries for which this information was available in 2005.1 In addition to reviewing the state of bycatch data and estimation, this report establishes a baseline for tracking changes in bycatch over time, and is designed to assist NMFS in meeting legislative mandates for bycatch reduction, guiding policy, and setting priorities"--Executive summary.

Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.
