Book excerpt: "Opportunistic reports were used to measure levels of human - caused serious injury and mortality to baleen whale stocks along the United States east coast and Atlantic Canadian Provinces for 2009 through 2013. Whale injury and mortality events were evaluated using criteria for injury severity and for assigning injuries and mortalities to natural or human causes. The average annual human-caused serious injury and mortality rate during the period was 4.55 for North Atlantic right whales, 9.0 for Gulf of Maine humpback whales, 3.55 for Western North Atlantic fin whales, 0.4 for Nova Scotian sei whales, 7.7 for Canadian East Coast minke whales, 0.2 for Northern Gulf of Mexico Bryde's whales, and 0 for Western North Atlantic blue whales. The number of serious injuries and mortalities not reported is unknown, and actual levels may be much higher"--Abstract. [doi:10.7289/V5C53HTB (http://dx.doi.org/10.7289/V5C53HTB)]

Glass and published by . This book was released on 2012 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Northeast Fisheries Science Center (NEFSC) has developed criteria to evaluate reports of human-caused injury and mortality to large whales. The criteria minimize the likelihood of incorrectly assigning whale mortalities and serious injuries to human causes and provide a minimum count of such human-caused incidents. Serious injury is defined as an injury that is likely to lead to death. This report describes determinations made for reports received from 2006 - 2010 involving North Atlantic right (Eubalaena glacialis), humpback (Megaptera novaeangliae), fin (Balaenoptera physalus), sei (B. borealis), blue (B. musculus), minke (B. acutorostrata), and Bryde's (B. edeni) whales observed along coastal Gulf of Mexico, the eastern seaboard of the United States, and the Atlantic Canadian provinces. A total of 500 unique large whale events were verified during the period, of which 264 (53%) involved human interactions, 16 (3%) did not involve a human interaction, and for 220 (44%) of the events it was unknown if a human interaction occurred. Of the events involving human interactions, we confirmed 206 unique entanglements and 58 vessel strikes. Four events had evidence of both entanglement and vessel strike, and are included in the totals for both these event categories. Twenty-four (12%) of the entanglements and 28 (48%) of the vessel strikes were fatal. Serious injury was sustained in 33 (16%) of the entanglement events and in 1 (2%) of the confirmed vessel strikes. Serious injury was prevented due to disentanglement efforts in 28 (14%) entanglement events. Forty-five (22%) of the entanglements and 9 (16%) of the vessel strike events did not have adequate documentation to determine if serious injury occurred. Seventy-three (35%) of the entanglement events and 17 (29%) of the vessel strike events were determined to have not caused serious injury or death. We also confirmed a total of 313 mortalities: 52 (17%) due to human interaction, 16 (5%) due to natural causes and 245 (78%) which lacked sufficient evidence to determine cause of death. Humpback whales had the greatest number of entanglement mortalities (n=9), the highest number of serious injury events resulting from entanglements (n=20); and the greatest number of vessel strike mortalities (n=10); and right whales had the only serious injury (n=1) from vessel strikes. These mortality and serious injury numbers are minimum counts because of poor detection probabilities and inadequate documentation for the majority of events. Thus, the true level of human impact to these stocks is assumed to be greater than that reported here; the amount greater is unknown"--Abstract.

Cole and published by . This book was released on 2013 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Marine Mammal Protection Act (MMPA) requires NMFS to estimate annual levels of human-caused mortality and serious injury to marine mammal stocks (section 117), and to categorize commercial fisheries based on their level of incidental mortality and serious injury of marine mammals (section 118). Serious injury (SI) determinations were addressed at NMFS convened workshops in 1997 and 2007 (Angliss and DeMaster 1998; Andersen et al. 2008), and in January 2012, the agency published new national guidelines for distinguishing serious from non-serious injuries of marine mammals 1. A major goal of the new guidelines is to establish national consistency and transparency in SI determinations. As part of implementing the new guidelines, Science Center SI experts from each region reviewed all documented marine mammal injury events during the 5-year period of 2007-2011. Reports and images of injuries and the animals' condition were compared to injury categories described in the new guidelines' procedure manual, and each event was assigned an injury determination. The resulting SI values were combined with anthropogenic mortality values for comparison to each stock's Potential Biological Removal (PBR) in annual marine mammal stock assessment reports (SARs). This report summarizes the SI determinations for baleen whale stocks along the Gulf of Mexico, United States east coast and Atlantic Canadian Provinces for 2007 through 2011"--Introduction.

Book excerpt: "The Northeast Fisheries Science Center (NEFSC) has developed criteria to evaluate reports of human-caused injury and mortality to large whales. The criteria minimize the identification of false positive human-caused mortalities and serious injuries and provide a minimum value of human impact to whale stocks. Serious injury is defined as an injury that is likely to lead to death. This report describes determinations made for reports received from 2005 - 2009 involving North Atlantic right (Eubalaena glacialis), humpback (Megaptera novaeangliae), fin (Balaenoptera physalus), sei (B. borealis), blue (B. musculus), minke (B. acutorostrata), and Bryde's (B. edeni) whales observed along coastal Gulf of Mexico and the eastern seaboard of the United States and adjacent Canadian Maritimes.

Of the human-caused mortalities, 32 were due to entanglement and 28 were vessel strike. These mortality numbers are minimum counts because of a low probability of detecting events and inadequate documentation to determine cause of death for the majority of events that are detected. Despite the minimum values, the mean annual confirmed human-caused mortality rate exceeds the Potential Biological Removal (PBR) value for 4 of the 7 stocks examined, including North Atlantic right, humpback, sei, and Bryde's whales. The true level of anthropogenic mortality to these stocks is greater than these minimum values, but the amount greater is unknown.

This book was released on 2007 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Northeast Fisheries Science Center (NEFSC) has developed protocols for determining large whale serious injuries and human-caused mortalities. This report describes determinations made for events occurring from 2001-2005 involving stocks of right, humpback, fin, sei, blue, minke, and Brydes whales along the eastern seaboard of the United States and adjacent Canadian Maritimes. A total of 417 unique large whale events was reported during the period, including carcasses (both beached and at sea) and live whales sighted at sea. We received 151 entanglement reports and 48 reports of ship strikes. We were able to verify 133 entanglement events, 42 ship strikes, and 292 mortalities. Entanglements were identified as the cause of 26 whale deaths and ship strikes the cause of 27; 223 mortalities (76%) lacked sufficient evidence to determine cause of death. Entanglements were determined to have caused serious injury in 11 events, and 1 serious injury was caused by a vessel strike. Seventy (53%) of the verified entanglement events and 9 (21%) of the ship strike events were determined to have not caused serious injury or death; 21 (16%) entanglement events and 2 (5%) ship strike events lacked sufficient evidence for determination. Minke whales had the greatest number of entanglement mortalities (n=11). Humpback whales had the highest number of serious injury events resulting from entanglements (n=6). Right whales and fin whales both had 8 mortalities from ship strikes. These human-caused mortality and serious injury rates represent the minimum levels of impact to these stocks.

This book was released on 2006 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Northeast Fisheries Science Center has developed protocols for determining large whale serious injuries and human-caused mortalities. This report describes determinations made for right, humpback, fin, sei, blue, minke and Brydes whale events that occurred from 2000 through 2004 along the eastern seaboard of the United States. A total of 417 unique large whale events were reported during the period, including both carcasses stranded on beaches and sighted at sea. These included 171 entanglement reports and 42 reports of ship strikes. We were able to verify 147 entanglement events, 29 ship strikes, and 276 mortalities. Entanglements were identified as the cause of 27 whale deaths and ship strikes the cause of 21. Entanglements were determined to have caused serious injury in 18 events. Minke whales had the greatest number of entanglement mortalities (12). Humpback whales had the highest number of serious injury events resulting from entanglements (11) and the most incidents of ship strike mortalities (7). Right whales had six mortalities from ship strikes and fin whales had five. No serious injuries resulting from ship strikes were confirmed for any species. These human-caused mortality and serious injury rates represent the minimum levels of impact to these stocks. Procedures and methods for estimating actual serious injury and mortality rates have yet to be developed"--Abstract.
