Book Description
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)]

The primary marine mammals interacting with this fishery were pilot whales (Globicephala sp.) with an estimated 35.7 (14.0 - 90.6 [95% CI]) interactions and Risso's dolphins (Grampus griseus)with 38.5 (16.0 - 92.6 [95% CI]) interactions. Potential sources of bias and uncertainty in these by catch estimates are discussed. The estimates for each of these species are lower than prior years, and the estimated bycatch of loggerhead turtles is substantially lower than that occurring since 2006"--Abstract.

Book Description
"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 Description
"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.
