| conservation in the first internal transcribed spacer (its1) region of hematodinium perezi (genotype iii) from callinectes sapidus . | hematodinium spp. infections have been reported from blue crabs callinectes sapidus in high-salinity waters of the usa from new jersey to texas. recently, h. perezi (genotype iii) has been proposed as the parasite species and genotype infecting blue crabs from virginia; however, it is unknown whether this same genotype is present in blue crabs from other locations. to address this question, we collected 317 blue crabs from massachusetts, virginia, georgia, florida, louisiana, and texas to test f ... | 2013 | 23482386 |
| bacteriological survey of the blue crab industry. | during sanitation inspections of 46 crabmeat processing plants on the atlantic and gulf coasts, 487 samples of whole crabs immediately after cooking, cooked crabs after cooling, backed or washed (or both) crab bodies and whole crab claws, as well as 1,506 retail units of finished product were collected and analyzed bacteriologically. the 1,506 retail units (1-lb [373.24-g] cans) included 518 cans of regular (special) meat, 487 cans of claw meat, and 501 cans of lump meat. statistical analyses sh ... | 1972 | 4568256 |
| temperature correlates with annual changes in hematodinium perezi prevalence in blue crab callinectes sapidus in florida, usa. | blue crabs callinectes sapidus were monitored biannually throughout florida, usa, for 2 yr using a highly sensitive, quantitative polymerase chain reaction (qpcr) to determine the spatial and temporal changes in prevalence and intensity of hematodinium perezi infections during drought years. despite persistent drought conditions, h. perezi infections were not universally found. overall prevalence was 25.3% (95% ci: 22.8-28.1%) in 1066 crabs sampled from 6 locations (jacksonville, ormond beach, e ... | 2015 | 25850401 |
| accumulation of organic and inorganic contaminants in shellfish collected in estuarine waters near pensacola, florida: contamination profiles and risks to human consumers. | we conducted a screening level assessment of contaminants in blue crabs (callinectes sapidus) and oysters (crassostrea virginica) from bays and bayous in the pensacola, fl area. tissue samples were analyzed for 17 dioxins/furans, 12 dioxin-like pcb (dl-pcbs) congeners, mercury, and various metals. contaminant levels were compared to screening values (sv) calculated using u.s. epa recommendations for establishing consumption advisories. all sampling locations exceeded the sv (0.098pgg(-1)) for di ... | 2007 | 16872729 |
| evaluation of a florida coastal golf complex as a local and watershed source of bioavailable contaminants. | contaminant fate in coastal areas impacted by golf course runoff is not well understood. this report summarizes trace metal, pesticide and pcb residues for colonized periphyton, ruppia maritima (widgeon grass), callinectes sapidus rathbun (blue crabs) and crassostrea virginica gemlin (eastern oyster) collected from areas adjacent to a florida golf course complex which receive runoff containing reclaimed municipal wastewater. concentrations of 19 chlorinated pesticides and 18 pcb congeners were u ... | 2004 | 14972577 |
| et743: chemical analysis of the sea squirt ecteinascidia turbinata ecosystem. | the sea squirt ecteinascidia turbinata produces the powerful drug et743. in this study inductively coupled plasma-atomic emission spectroscopy (icp-aes) and matrix assisted laser desorption ionization-mass spectrometry (maldi-ms) are systematically used to measure elemental and molecular species in a florida keys mangrove ecosystem that contains the sea squirt. icp-aes is used to measure the concentration of 27 elements down to the parts per billion level in 16 organisms and 3 sediment samples t ... | 2006 | 16644544 |
| mercury, lead, and cadmium in blue crabs, callinectes sapidus, from the atlantic coast of florida, usa: a multipredator approach. | blue crabs, callinectes sapidus, from the atlantic coast of florida were analyzed for total mercury, methylmercury, lead, and cadmium. paired samples of two tissue types were analyzed for each crab, (1) muscle tissue (cheliped and body muscles) and (2) whole-body tissue (all organs, muscle tissue and connective tissue), for evaluation of the concentration of metals available to human consumers as well as estuarine predators. there were clear patterns of tissue-specific partitioning for each meta ... | 2014 | 24507459 |
| exuviotrophic apostome ciliates from crustaceans of st. andrew bay, florida, and a description of gymnodinioides kozloffi n. sp. | gymnodinioides kozloffi n. sp. is described from the eelgrass broken-back shrimp hippolyte zostericola. the species is distinct from others in the apostome genus gymnodinioides in that the trophont ciliature has a small group of kinetosomes located to the right of kinety 9a, and kinety 1 and 2 are divided. other apostome morphologies are described from many decapod crustaceans from st. andrew bay, florida, including gymnodinioides inkystans, hyalophysa chattoni, and variants of both h. chattoni ... | 2004 | 15666721 |
