This book was released on 2006 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The prevalence of non-lethal entanglements of humpback whales (Megaptera novaeangliae) in fishing gear in northern southeastern Alaska (SEAK) was quantified using a scar-based method. The percentage of whales assessed to have been entangled ranged from 52% (minimal estimate) to 71% (conditional estimate) to 78% (maximal estimate). The conditional estimate is recommended because it is based solely on unambiguous scars. Eight percent of the whales in Glacier Bay/Icy Strait acquired new entanglement scars between years, although the sample size was small. Calves were less likely to have entanglement scars than older whales and males may be at higher risk than females. The temporal and spatial distribution of commercial fisheries is complex and difficult to correlate with these results. The percentage of whales with entanglement scarring is comparable to the Gulf of Maine where entanglement is a substantial management concern. Consequently, SEAK humpback whale-fisheries interactions may warrant a similar level of scrutiny"--Leaf iii.

This book was released on 2013 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large whale entanglement in commercial fishing gear off the U.S. west coast has been identified as an issue of concern by NOAA's National Marine Fisheries Service (NMFS) because of the potential impacts to both large whales (individually and at a stock/population level) and the commercial fishing industry. Large whales entangled in gear may be injured and/or impared which could affect the ability of individuals to survive and a population's ability to recover. Blue whales (Balaenoptera musculus), fin whales (Balaenoptera physalus), gray whales (Eschrichtius robustus), humpback whales (Megaptera novaeangliae) and sperm whales (Physeter macrocephalus) were included in this study based on their distribution and density associated with habitat, as modeled through multi-year ship-based surveys or migration studies and/or historic entanglement records. Along the U.S. west coast, an average of 10 large whales have been reported entangled between 2000 and 2012. Little information has been confirmed from entanglement reports about the origin of the entangling fishing gear; therefore NMFS has developed analytical tools to assess the potential entanglement risk associated with various fixed gear fisheries relative to their co-occurrence with large whale species. A primary tool includes the development of a model to represent the spatial and temporal distributions of commercial fishing effort, focusing on fixed gear fisheries with gear that has been confirmed as entangling whales through sightings and strandings of entangled animals and or has the potential for causing entanglement based on similarities in the general configuration of gear across the fisheries. Fishing effort represented in this study, both state and federally managed, was derived from landings data obtained through the Pacific Fisheries Information Network (PacFIN). The relative density of fishing effort throughout the calendar year was overlaid with species-specific whale distribution patterns, modeled from systematically-collected marine mammal survey data, to help identify spatial and temporal overlap between whales and fisheries. The other tool developed, a co-occurrence model, identified potential species-specific elevated risk areas where and when large whales are more likely to encounter fishing gear, which is the first step in assessment of whale entanglement risk associated with fixed-gear fisheries on the U.S. west coast. Co-occurrence "scores" were calculated based on correlated area, time, and density of overlap between fixed gear fisheries and whale distribution. Overall, the Dungeness crab trap fishery had the highest co-occurrence scores, and associated entanglement risk, with all whale species included in the model. Confirmed entanglement reports were compared with model results. Alignment of known entanglement locations with areas of higher co-occurrence scores supported the use of the co-occurrence model for assessment of whale entanglement risk off the U.S. west coast. Research on the identified elevated risk areas, combined with the ability to trace gear continued gear research, and strengthened outreach to improve reporting, should improve the ability to minimize or mitigate the risk of large whale entanglements.

Download or read book Entanglements written by Tora Johnson and published by . This book was released on 2005 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Entanglements explores the clash of cultures and personalities among fishermen, scientists, and whale advocates struggling to save both the endangered North Atlantic right whale and the livelihoods of thousands of Atlantic coastal families. By most counts, about 300 of these whales remain in the North Atlantic, and scientists warn that collisions with fishing gear are contributing to their decline. The political climate that surrounds the world's most endangered large whale is contentious, complex, and heartrending. Without pointing fingers or laying blame, Tora Johnson explores every side of the issue. She takes us to sea with fishermen who struggle to stay in business, setting traps and gillnets in the whale's habitat, and with members of the rescue teams who attempt to cut away deadly rope and net from whales in the wild. Weaving their stories and her personal observations into a discussion of the science and history of the conflict, she offers an admirable balance of perceptions, backgrounds, and agendas. Her thoughtful discussion of the plight of fishermen and whales and of the frustrations between fishing communities and conservationists presents an authentic microcosm of the global conflict between human demands on the environment and nature's finite capacity for supporting those demands.

Available in PDF, EPUB and Kindle. Book excerpt: "Marine scientist Michael J. Moore says we are all whalers, but we don't have to be. Eating fish leads to North Atlantic right whales' entanglement and death. Buying goods made around the world requires global shipping routes, which do not accurately consider right whale breeding and feeding sites, leading to collision. To explain this, Moore conveys to readers scenes from over thirty years' worth of fieldwork, performing whale necropsies for animals stranded on beaches, working as an independent researcher alongside whalers using explosive harpoons, and tracking injured pregnant whales to deliver antibiotics. Despite these sometimes disturbing experiences, Moore has written a hopeful book. He uses these stories to show we can change and to tell us how; the technology for rope-less fishing and tracking whale migrations already exist to protect both right whales and the people who depend on shipping and fishing for their livelihoods"--
Download or read book Assessment of Entanglement Risk written by Samantha C. Macks and published by . This book was released on 2018 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 2014, reports of whale entanglements have spiked along the U.S. West Coast from an average of 10 confirmed cases per year to up to 71 reported entanglements in 2016. The commercial fixed gear Dungeness crab (Cancer magister) fishery has been the most identifiable gear in confirmed whale entanglements. The continued high number of reported whale entanglements has warranted fishery managers, fishermen, and other stakeholders to look into solutions to reducing the number of entangled whales; however, a better understanding of where and why these entanglement rates have spiked is needed. Previous efforts by National Marine Fisheries Service (NMFS) to understand entanglement risk designed a co-occurrence model to assess entanglement risk along the West Coast by overlaying landings data with species-specific whale density and distribution patterns to produce relative co-occurrence scores as an indicator for risk. The purpose of this study was to create a vertical line co-occurrence model between large whales and the commercial Dungeness crab fishery; as NMFS indicated in their previous model, that the use of gear density instead of the number of pounds landed to represent fishing effort provides a better understanding of high entanglement risk areas. This research provides a comparison to previous co-occurrence modeling efforts, highlights the areas and months of high entanglement risk, and compares risk areas over several time periods. The vertical line co-occurrence models piloted in this study created a new understanding of areas of entanglement risk for large whales in recent years to aid future efforts by NMFS and fishery managers to mitigate large whale entanglements.
