Download or read book Estimates of Marine Mammal and Marine Turtle Bycatch by the U S Atlantic Pelagic Longline Fleet in 1998 written by Cynthia Yeung and published by . This book was released on 1999 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report presents the 1998 estimates of the bycatch of marine mammal and sea turtle taken by the part of the U.S. Atlantic pelagic longline fleet that lands tuna and Atlantic swordfish. The information is required by NOAA Fisheries to meet its responsibility for management of interactions between protected species and commercial fisheries based on the level of incidental serious injury and mortality. Serious injury is defined under proposed guidelines drafted by the NOAA Office of Protected Resources, and is equated to mortality for the purpose of bycatch estimation. Estimates were based on bycatch rates from a representative sample of the fleet recorded by scientific observers, and fishing effort reported by the fleet. Bycatch rates reported by the fleet were omitted. Estimates were constructed using the Delta-lognormal method. Robustness of the estimates to geographical and temporal effects was examined by pooling across strata (calendar quarters, fishing areas, and groups of species). Point estimates of bycatch were relatively insensitive to pooling treatments, but gains in precision of estimates (coefficient of variation) were attained in cases where bycatch numbers were relatively high. The total observed bycatch in 1998 amounted to six for marine mammals and 20 for marine turtles. Extrapolated to total fleet effort, the most precise estimate (pooling within years, within the three major fishing areas, and grouping of species) indicates that the US pelagic longline fleet operating in the Atlantic caught a total of 205 (57-828, 95%CI) marine mammals in 1998. Of these, the estimated number of marine mammals that were dead or seriously injured and thus presumed dead is 54 (10-277, 95% CI). For marine turtles, an estimated total of 728 (337-1824, 95%CI) were caught by the fleet in 1998. Of these, the estimated number that were dead or seriously injured and presumed dead is 708 (324-1788, 95% CI). Both marine mammals and turtles were mostly caught from the Grand Banks (Northeast Coastal region) fishing area of the US Atlantic EEZ"--Summary.

This book was released on 2004 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The U.S. Atlantic pelagic longline fleet operates throughout the Gulf of Mexico, along the entire U.S. Atlantic coast over the continental shelf and slope, and in distant water areas including the central North Atlantic and the Canadian Grand Banks. The Atlantic longline fleet is defined as a Category I fishery under the Marine Mammal Protection Act, and it is also the subject of management concerns under the Endangered Species Act due to interactions with marine turtles including leatherback and loggerhead turtles. Using data from the pelagic longline fishery observer program and a mandatory fishery logbook reporting program, total bycatch of marine mammals and turtles in the longline fishery was estimated for the year 2003. A delta-lognormal approach was applied to estimate region specific and total annual interactions and mortality for the fishery. Total interactions observed during an experimental fishery in waters off of the Canadian Grand Banks are also documented. Any effort fished under a excepted fishing permit (EFP) and not reported in logbooks is not included herein. The primary marine mammal species interacting with this fishery were Risso's dolphin (Grampus griseus) and pilot whales (Globicephala sp .). Marine turtles that interacted with this fishery were primarily leatherback turtles (Dermochelys coriacea) and loggerhead turtles (Caretta caretta). Potential sources of bias and uncertainty in these bycatch estimates are discussed"--Abstract.

This book was released on 2009 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea turtles are affected by a range of different factors, some natural and others caused by human activities, including fishing operation. As a result, all sea turtles species whose conservation status has been assessed are considered to be threatened or endangered. These guidelines provide assistance for the preparation of national or multilateral fisheries management measures and industry initiatives that may help to conserve sea turtles by reducing the negative impacts that fisheries may have on them. They present our best understanding of how to reduce the proportion of caught turtles that are killed as a result of interactions with marine capture fisheries. These guidelines include information about how to change fishing gear and fishing methods and how the fishing industry can adopt voluntary approaches to reduce sea turtle mortality.--Publisher's description.

This book was released on 2013 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Atlantic Pelagic Longline fleet operates throughout the northwestern Atlantic Ocean, including along the U.S. coast from the Gulf of Mexico to New England, the waters of the Caribbean, and in international waters of the North Atlantic Ocean. The Atlantic longline fleet is defined as a Category I fishery under the Marine Mammal Protection Act, and it is also the subject of management under the Endangered Species Act due to interactions with leatherback (Dermochelys coriacea) and loggerhead (Caretta caretta) turtles. Total bycatch of marine mammals and turtles in the longline fishery was estimated for 2012 using data from the pelagic longline fishery observer program and a mandatory fishery logbook reporting program. We applied a delta-lognormal approach to estimate region specific and total annual interactions with protected species in the fishery. During 2012 , there were an estimated 596.2 (424.7-837.0 [95% CI]) interactions with leatherback turtles and 680.7 (518.0-894.5 [95% CI]) interactions with loggerhead turtles. The primary marine mammals interacting with this fishery were pilot whales (Globicephala sp.) with an estimated 242.6 (145.8-404.0 [95% CI]) interactions with unspecified pilot whales and an additional 10.0 ( 2.0-51.0 [95% CI]) interactions with genetically identified short-finned pilot whales.

Book excerpt: "In this report, marine mammal and marine turtle bycatch estimates are calculated for pelagic longline fishery effort during 2007. Bycatch rates (catch per 1000 hooks) are quantified based upon observer data by fishing area and quarter. The estimated bycatch rate is then multiplied by the total fishing effort (number of hooks) reported to the FLS program to obtain estimates of total interactions for each species of marine mammal and turtle"--Page 7.

Book excerpt: The U.S. Atlantic Pelagic Longline fleet operates throughout the northwestern Atlantic Ocean, including along the U.S. coast from the Gulf of Mexico to New England, the waters of the Caribbean, and in international waters of the North Atlantic Ocean. The Atlantic longline fleet is defined as a Category I fishery under the Marine Mammal Protection Act, and it is also the subject of management under the Endangered Species Act due to interactions with leatherback (Dermochelys coriacea) and loggerhead (Caretta caretta) turtles. Total bycatch of marine mammals and turtles in the longline fishery was estimated for 2014 using data from the pelagic longline fishery observer program and a mandatory fishery logbook reporting program. We applied a delta-lognormal approach to estimate region specific and total annual interactions with protected species in the fishery. During 2014, there were an estimated 281.0 (200.3 – 394.9 [95% CI]) interactions with leatherback turtles and 260.9 (167.3 – 407.6 [95% CI]) interactions with loggerhead turtles. In addition, there were an estimated 6.2 (1.6 – 23.7 [95% CI])interactions with Olive Ridley turtles. The primary marine mammals interacting with this fishery were pilot whales (Globicephala sp.) in Western North Atlantic waters. Interactions were apportioned between short-finned and long-finned pilot whales based upon location and environmental parameters. The majority of interactions were with short-finned pilot whales with an estimated 233.4 (145.9 – 73.2 [95% CI]) interactions resulting in serious injury and an additional 40.4 (15.8 – 103.4 [95% CI]) interactions in which the animal was released alive. Potential sources of bias and uncertainty in these bycatch estimates are discussed. [doi:10.7289/V5/TM-SEFSC-696 (https://doi.org/10.7289/V5/TM-SEFSC-696)]
