Unnatural Selection of Antarctic Toothfish in the Ross Sea, Antarctica
Historically, fishermen targeted fish in shallow, nearshore waters relatively close to port (Pauly et al. 2005). As these species became depleted, to meet growing demands, fishermen were forced to move offshore and into deeper waters (Hutchings and Reynolds 2004; Koslow et al. 2000; Morato et al. 2006; Hilborn et al. 2003; Pauly et al. 2002, 2005). Steady advances in fishing technology facilita...
متن کاملSeafood Substitutions Obscure Patterns of Mercury Contamination in Patagonian Toothfish (Dissostichus eleginoides) or “Chilean Sea Bass”
Seafood mislabeling distorts the true abundance of fish in the sea, defrauds consumers, and can also cause unwanted exposure to harmful pollutants. By combining genetic data with analyses of total mercury content, we have investigated how species substitutions and fishery-stock substitutions obscure mercury contamination in Patagonian toothfish (Dissostichus eleginoides), also known as "Chilean...
متن کاملPopulation genetic structure of Patagonian toothfish (Dissostichus eleginoides) in the Southeast Pacific and Southwest Atlantic Ocean
Previous studies of population genetic structure in Dissostichus eleginoides have shown that oceanographic and geographic discontinuities drive in this species population differentiation. Studies have focused on the genetics of D. eleginoides in the Southern Ocean; however, there is little knowledge of their genetic variation along the South American continental shelf. In this study, we used a ...
متن کاملPopulation Genetic Structure of Patagonian Toothfish in the West Indian Ocean Sector of the Southern Ocean
Molecular markers were used to investigate the stock structure of Patagonian toothfi sh (Dissostichus eleginoides) in the West Indian Ocean sector of the Southern Ocean. Four collections of D. eleginoides from Kerguelen (n = 1), Crozet (n = 1) and Prince Edward and Marion (n = 2) Islands were typed using two fragments of mitochondrial DNA (mtDNA) and seven nuclear microsatellite loci. MtDNA hap...
متن کاملSouthern elephant seals (Mirounga leonina Linn.) depredate toothfish longlines in the midnight zone
Humans have devised fishing technologies that compete with marine predators for fish resources world-wide. One such fishery for the Patagonian toothfish (Dissostichus eleginoides) has developed interactions with a range of predators, some of which are marine mammals capable of diving to extreme depths for extended periods. A deep-sea camera system deployed within a toothfish fishery operating i...
