| organochlorine contaminants in fishes from coastal waters west of amukta pass, aleutian islands, alaska, usa. | organochlorines were examined in liver and stable isotopes in muscle of fishes from the western aleutian islands, alaska, in relation to islands or locations affected by military occupation. pacific cod (gadus macrocephalus), pacific halibut (hippoglossus stenolepis), and rock greenling (hexagrammos lagocephalus) were collected from nearshore waters at contemporary (decommissioned) and historical (world war ii) military locations, as well as at reference locations. total (sigma) polychlorinated ... | 2009 | 19374473 |
| killer whale depredation and associated costs to alaskan sablefish, pacific halibut and greenland turbot longliners. | killer whale (orcinus orca) depredation (whales stealing or damaging fish caught on fishing gear) adversely impacts demersal longline fisheries for sablefish (anoplopoma fimbria), pacific halibut (hippoglossus stenolepis) and greenland turbot (reinhardtius hippoglossoides) in the bering sea, aleutian islands and western gulf of alaska. these interactions increase direct costs and opportunity costs associated with catching fish and reduce the profitability of longline fishing in western alaska. t ... | 2014 | 24558446 |
| genetic sex identification and the potential evolution of sex determination in pacific halibut (hippoglossus stenolepis). | the discovery of genetic markers linked to physiological traits in wild populations is increasingly desired for ecological and evolutionary studies, as well as to inform management decisions. however, identifying such markers often requires a large investment of both time and money. serendipitously, in a recent microsatellite survey, we discovered three out of 16 microsatellite loci that were correlated to the female sex in pacific halibut (hippoglossus stenolepis). these three loci were screene ... | 2011 | 21279406 |
| halibut mitochondrial genomes contain extensive heteroplasmic tandem repeat arrays involved in dna recombination. | halibuts are commercially important flatfish species confined to the north pacific and north atlantic oceans. we have determined the complete mitochondrial genome sequences of four specimens each of atlantic halibut (hippoglossus hippoglossus), pacific halibut (hippoglossus stenolepis) and greenland halibut (reinhardtius hippoglossoides), and assessed the nucleotide variability within and between species. | 2008 | 18186947 |
| mercury in fishes of alaska, with emphasis on subsistence species. | in the north, the presence of mercury (hg) in food leading to chronic exposure is a scientific, economic and political issue. guidelines have been established for the safe consumption of fish containing hg, however, adherence to these guidelines must be weighed against the health benefits of consuming fish, such as from the omega-3 polyunsaturated fatty acids, vitamins and minerals. alaskan natives generally consume much more fish than the national average. this review summarizes and synthesizes ... | 2007 | 17825359 |
| a biomonitoring plan for assessing potential radionuclide exposure using amchitka island in the aleutian chain of alaska as a case study. | with the ending of the cold war, the us and other nations were faced with a legacy of nuclear wastes. for some sites where hazardous nuclear wastes will remain in place, methods must be developed to protect human health and the environment. biomonitoring is one method of assessing the status and trends of potential radionuclide exposure from nuclear waste sites, and of providing the public with early warning of any potential harmful exposure. amchitka island (51 degrees n lat, 179 degrees e long ... | 2007 | 17683832 |
| radionuclides in marine fishes and birds from amchitka and kiska islands in the aleutians: establishing a baseline. | amchitka island (51degrees n lat, 179 degrees e long) was the site of three underground nuclear tests from 1965-1971. there have been no substantive studies of radionuclides in marine fishes and birds in the area since the mid-1970's. in this study, levels of 60co, 52eu, 90sr, 99tc, 129i, 137cs, and the actinides (241am, 238pu, 239,240pu, 234u, 235u, 236u, and 238u) were studied in ten marine fish species (including pacific cod gadus macrocephalus and pacific halibut hippoglossus stenolepis) and ... | 2007 | 17293699 |
| isolation, characterization, and radioimmunoassay of atlantic halibut somatolactin and plasma levels during stress and reproduction in flatfish. | somatolactin (sl), a recently identified teleost pituitary hormone which is a member of the growth hormone/prolactin family, was isolated from pituitary tissue of atlantic halibut (hippoglossus hippoglossus). pituitary proteins were extracted in ammonium bicarbonate (ph 7.8), fractionated using gel filtration chromatography, and purified using reversed-phase high-performance liquid chromatography. halibut sl was identified on the basis of molecular size (determined by gel electrophoresis and mas ... | 1997 | 9038252 |
