Description:

"This report provides incidental take estimates for seven marine mammal species observed taken in the 2007 and 2008 Northeast sink gillnet (NESG) and Mid-Atlantic gillnet (MAG) fisheries and documents the methodology used to produce the estimates. The estimated incidental takes in the 2007 NSEG fishery were 11 (CV = 94%) common dolphins (Delphinis delphis), 395 (CV = 38%) harbor porpoises (Phocoena phocoena), 889 (CV = 24%) gray seals (Halichoerus grypus), 93 (CV = 49%) harbor seals (Phoca vitulina), and 119 (CV = 36%) harp seals (Phoca groenlandica). For the MAG fishery, the estimated 2007 incidental takes was 59 (CV = 104%) harbor porpoises, 38 (CV = 90%) harp seals, and 34 (CV = 73%) Risso's dolphin (Grampus griseus). The estimated incidental takes in the 2008 NESG fishery, were 666 (CV = 0.48) harbor porpoises, 34 (CV = 77%) common dolphins, 81 (CV = 57%) white-sided dolphins (Lagenorhynchus acutus), 618 (CV = 23%) gray seals, 243 (CV = 41%) harbor seals, and 238 (CV = 38%) harp seals. For the MAG fishery, the estimated 2008 incidental takes were 350 (CV = 75%) harbor porpoises, 88 (CV = 74%) harbor seals, and 176 (CV = 74%) harp seals"--Abstract.
