| co-exposure to sunlight enhances the toxicity of naturally weathered deepwater horizon oil to early lifestage red drum (sciaenops ocellatus) and speckled seatrout (cynoscion nebulosus). | the 2010 deepwater horizon oil spill resulted in the accidental release of millions of barrels of crude oil into the gulf of mexico. photo-induced toxicity following co-exposure to ultraviolet (uv) radiation is 1 mechanism by which polycyclic aromatic hydrocarbons (pahs) from oil spills may exert toxicity. red drum and speckled seatrout are both important fishery resources in the gulf of mexico. they spawn near-shore and produce positively buoyant embryos that hatch into larvae in approximately ... | 2017 | 27868239 |
| sensory development and its relation to habitat change in three species of sciaenids. | visual and mechanosensory development of three sciaenid species was investigated to examine possible correlations between sensory morphology and patterns of habitat use. although the three species have different migration patterns as early larvae, few differences in sensory morphology occurred between species until late in the larval period. atlantic croaker, micropogonias undulatus, were distinguished by enhancements of visual morphology (large eyes, abundant photoreceptors, and best summation ... | 1998 | 9807012 |
| quantifying the seafood consumption patterns of recreational anglers in charleston and berkeley counties, south carolina. | this study was designed to provide self-reported data on the frequency of fish consumption and shellfish consumption in charleston and berkeley (cb) counties, south carolina. while commercial fishing and recreational fishing have played an important role in the culture and history of the area, information on the specific patterns of consumption by recreational anglers has been previously unavailable. the pilot data presented here will help determine the feasibility of a large-scale survey of sea ... | 2016 | 27891049 |
| vitrification of sperm from marine fishes: effect on motility and membrane integrity. | our goal was to develop a standardized approach for sperm vitrification of marine fishes that can be applied generally in aquatic species. the objectives were to: 1) estimate acute toxicity of cryoprotectants over a range of concentrations; 2) evaluate the properties of vitrification solutions (vs); 3) evaluate different thawing solutions, and 4) evaluate sperm quality after thawing by examination of motility and membrane integrity. sperm were collected from red snapper (lutjanus campechanus), s ... | 2015 | 26074721 |
| philometra floridensis sp. n. (nematoda: philometridae) from the ovary of red drum sciaenops ocellatus (osteichthyes: sciaenidae) off the coast of florida, usa. | a new nematode species, philometra floridensis sp. n. (philometridae), is described from male and female specimens found in the ovary of red drum, sciaenops ocellatus (linnaeus) (sciaenidae, perciformes), from the gulf of mexico off treasure island, florida, usa. based on light and scanning electron microscopy examination, the new species differs from most other gonad-infecting philometra spp. in having a smooth gubernaculum with a distinct dorsal tooth on the distal tip. the new species is most ... | 2010 | 19580690 |
| oxygen dependence of upper thermal limits in fishes. | temperature-induced limitations on the capacity of the cardiorespiratory system to transport oxygen from the environment to the tissues, manifested as a reduced aerobic scope (maximum minus standard metabolic rate), have been proposed as the principal determinant of the upper thermal limits of fishes and other water-breathing ectotherms. consequently, the upper thermal niche boundaries of these animals are expected to be highly sensitive to aquatic hypoxia and other environmental stressors that ... | 2016 | 27591316 |
| fish otolith asymmetry: morphometry and modeling. | mathematical modeling suggests that relatively large values of otolith mass asymmetry in fishes can alter acoustic functionality and may be responsible for abnormal fish behavior when subjected to weightlessness during parabolic or space flight [d.v. lychakov, y.t. rebane, otolith mass asymmetry in 18 species of fish and pigeon, j. grav. physiol. 11 (3) (2004) 17-34; d.v. lychakov, y.t. rebane, fish otolith mass asymmetry: morphometry and influence on acoustic functionality, hear. res. 201 (2005 ... | 2006 | 16859847 |
| detection of antimicrobial peptides related to piscidin 4 in important aquacultured fish. | epithelial surfaces of fish, such as the gut, skin and gills, comprise a large surface area for possible pathogen invasion. antimicrobial peptides (amps), innate immunity components, play a significant role in protecting fish. piscidins are a family of amps. in this study, we detected the presence of the recently discovered piscidin 4 via bug blot, western blot, elisa and/or immunohistochemistry in striped bass (morone saxatilis), white bass (m. chrysops), european seabass (dicentrarchus labrax) ... | 2010 | 19913049 |
| effects of the synthetic pyrethroid insecticide, permethrin, on two estuarine fish species. | limited toxicity data are available for estuarine and marine species and the widely used pyrethroid insecticide, permethrin. this study determined acute effects of permethrin on survival, lipid peroxidation, acetylcholinesterase activity, and splenocyte proliferation for two fish species found in south carolina estuaries; juvenile red drum (sciaenops ocellatus) and adult mummichog (fundulus heteroclitus). juvenile s. ocellatus were significantly more sensitive than adult f. heteroclitus to perme ... | 2011 | 21756140 |
| cloning and phylogenetic relationship of red drum somatolactin cdna and effects of light on pituitary somatolactin mrna expression. | the nucleotide sequence for red drum somatolactin (sl) cdna was determined and the expression of pituitary sl mrna was examined in red drum kept under various light conditions. a full length of sl cdna (1629 bp) was isolated and characterized from a red drum pituitary cdna library. the sl cdna has an open reading frame of 696 nucleotides which encodes a 24-amino-acid signal peptide and a 207-amino-acid mature peptide. red drum sl shares 58-87% amino acid sequence identity and 56-85% nucleotide s ... | 1999 | 9882545 |
| two new species of cardicola (digenea: sanguinicolidae) in drums (sciaenidae) from mississippi and louisiana. | two new species of cardicola (digenea: sanguinicolidae) are described from the heart of drums (perciformes: sciaenidae) in and off mississippi and louisiana. cardicola palmeri n. sp. infects the black drum, pogonias cromis, and, in mature individuals, is distinguished from its congeners by the combination of a body 1.9-2.9 times longer than wide, an esophagus 44-52% of the body length, posterior ceca 1.0-1.8 times longer than the anterior ones, a gland encircling the seminal vesicle that is 30-3 ... | 2004 | 15040679 |
