mercury accumulation in largemouth bass (micropterus salmoides) in a florida lake. | rates of mercury accumulation were examined in male and female largemouth bass (micropterus salmoides) from lake tohopekaliga, florida, to establish methods for fish consumption advisories for the protection of human health. in addition, concentrations were determined in five lower trophic level fish species. total mercury concentrations in adult largemouth bass muscle tissue ranged from 0.16 to 1.10 micrograms/g (fresh weight) and increased as fish increased in size and age. whole-body mercury ... | 1994 | 7811106 |
first isolation of largemouth bass virus. | the first reported fish kill caused by largemouth bass virus (lmbv) occurred in 1995 in santee-cooper reservoir, south carolina, usa. subsequently, this iridovirus has been implicated in additional fish kills and has also been found in clinically healthy fish in numerous locations in the southeastern usa. we compared the virus from santee-cooper reservoir with a virus isolated in 1991 from large-mouth bass, micropterus salmoides, from lake weir, florida. restriction fragment length polymorphisms ... | 2002 | 12219979 |
histologic and molecular characterization of edwardsiella piscicida infection in largemouth bass (micropterus salmoides). | the genus edwardsiella is composed of a diverse group of facultative anaerobic, gram-negative bacteria that can produce disease in a wide variety of hosts, including birds, reptiles, mammals, and fish. our report describes the isolation and identification of edwardsiella piscicida associated with chronic mortality events in 2 separate captive largemouth bass (micropterus salmoides) populations in new york and florida. wet-mount biopsies of skin mucus, gill, kidney, and spleen from several affect ... | 2016 | 26951328 |
organochlorine pesticides and thiamine in eggs of largemouth bass and american alligators and their relationship with early life-stage mortality. | thiamine deficiency has been linked to early mortality syndrome in salmonids in the great lakes. this study was conducted to compare thiamine concentrations in american alligators (alligator mississippiensis) and florida largemouth bass (micropterus salmoides floridanus) eggs from sites with high embryo mortality and high exposure to organochlorine pesticides (ocps) (lakes apopka and griffin, and emeralda marsh, florida, usa) to those from sites that have historically exhibited low embryo mortal ... | 2004 | 15650100 |
residues of organochlorine insecticides, polychlorinated biphenyls, and heavy metals in biota from apalachicola river, florida, 1978. | seventy-seven composite samples composed of largemouth bass ( micropterus salmoides ), channel catfish ( ictaluras punctatus), threadfin shad ( dorosoma petenense ), asiatic clam (corbicula fluminea ), burrowing mayfly ( hexagenia sp.), water snake ( natrix spp.), and little green heron ( butorides virescens ) were collected from upper and lower reaches of the apalachicola river, florida, in 1978 for residue analysis of organochlorine insecticides, pcbs (polychlorinated biphenyls), and metals. c ... | 2013 | 6427177 |
the complete mitochondrial genomes of largemouth bass of the northern subspecies (micropterus salmoides salmoides) and florida subspecies (micropterus salmoides floridanus) and their applications in the identification of largemouth bass species. | the largemouth bass belongs to the family centrarchidae, which includes two subspecies: the northern subspecies, micropterus salmoides salmoides, and the florida subspecies, micropterus salmoides floridanus. in this study, the complete mitochondrial genomes of the two subspecies were sequenced, and their genetic differences were identified. the mitogenomes of m. s. salmoides and m. s. floridanus are 16,486 and 16,479 bp in length, respectively. the two subspecies consisted of 37 genes (13 protei ... | 2012 | 22409750 |
largemouth bass (micropterus salmoides) and striped mullet (mugil cephalus) as vectors of contaminants to human consumers in northwest florida. | the health benefits of regular consumption of fish and seafood have been espoused for many years. however, fish are also a potential source of environmental contaminants that have well known adverse effects on human health. we investigated the consumption risks for largemouth bass (micropterus salmoides; n = 104) and striped mullet (mugil cephalus; n = 170), two commonly harvested and consumed fish species inhabiting fresh and estuarine waters in northwest florida. skinless fillets were analyzed ... | 2011 | 21764437 |
aphanomyces invadans and ulcerative mycosis in estuarine and freshwater fish in florida. | in the spring of 1998, the florida fish and wildlife research institute received numerous reports of lesioned or ulcerated fish primarily from the st. lucie estuary on the southeast coast of florida, an area known since the late 1970s for lesions of the ulcerative mycosis (um) type. from these and archived reports, as well as others received from different areas of florida, we documented that diseased specimens had randomly distributed skin ulcers (usually reddened or hemorrhagic) with raised ir ... | 2007 | 18236628 |
epizootiology of eustrongylides ignotus in florida: transmission and development of larvae in intermediate hosts. | under laboratory conditions, 2 modes of transmission of eustrongylides ignotus (nematoda: dioctophymatoidea) to fish were identified. eastern mosquitofish (gambusia holbrooki) became infected after ingestion of either eggs of e. ignotus containing first-stage larvae or aquatic oligochaetes (limnodrilus hoffmeisteri) containing third-stage larvae of e. ignotus. after removal from the uterus of gravid e. ignotus females and incubation for 17-28 days, depending on temperature, it was found that par ... | 2003 | 12760643 |
an epizootic of edwardsiella tarda in largemouth bass (micropterus salmoides). | edwardsiella tarda, an opportunistic bacterial pathogen, was isolated from dying largemouth bass (micropterus salmoides) during an epizootic in a eutrophic lake system, lochloosa lake, florida, usa. approximately 1,500 adult fish died over a 6-wk period during the late summer and early fall of 1991. a mixed population of aerobic bacteria (e. tarda, aeromonas hydrophila, and pseudomonas sp.) was isolated from deep cutaneous ulcers and intestines of moribund bass. however, e. tarda in pure culture ... | 1993 | 8487385 |
mercury stable isotopes in sediments and largemouth bass from florida lakes, usa. | humans and wildlife can be exposed to mercury (hg) through the consumption of fish with elevated concentrations of methylmercury (mehg). studies have shown that increased atmospheric deposition of hg often leads to increased mehg concentrations in aquatic organisms. however, depending on the ecosystem characteristics, reductions in hg emissions may not always lead to immediate decreases in fish mehg concentrations. measurements of natural abundance hg stable isotope ratios may enable a better un ... | 2013 | 23062970 |
ecological risk of methylmercury in everglades national park, florida, usa. | dramatic declines in mercury levels have been reported in everglades biota in recent years. yet, methylmercury (mehg) hot spots remain. this paper summarizes a risk assessment of mehg exposure to three piscivorous wildlife species (bald eagle, haliaeetus leucocephalus; wood stork, mycteria americana; and great egret, ardea albus) foraging at a mehg hot spot in northern everglades national park (enp). available data consisted of literature-derived life history parameters and tissue concentrations ... | 2008 | 18679795 |
