| relative sensitivity of six estuarine fishes to carbophenothion, chlorpyrifos, and fenvalerate. | the acute toxicity (96-hr lc50) of carbophenothion, chlorpyrifos, and fenvalerate to six estuarine fishes was determined in flow-through laboratory tests. the atherinid fishes (menidia menidia, m. peninsulae, m. beryllina, and leuresthes tenuis) consistently were among the most sensitive species tested and were similar to each other in their sensitivity to pesticides. the sensitivity of sheepshead minnows (cyprinodon variegatus) to carbophenothion was the same as that of the atherinids. for fenv ... | 1985 | 2419075 |
| predator-prey relations between age-1+ summer flounder (paralichthys dentatus, linnaeus) and age-0 winter flounder (pseudopleuronectes americanus, walbaum): predator diets, prey selection, and effects of sediments and macrophytes. | laboratory experiments and weekly trammel net surveys in the navesink river, new jersey (usa) were used to examine the predator-prey interaction between age-1+ summer flounder (paralichthys dentatus) and age-0 winter flounder (pseudopleuronectes americanus). winter flounder (24-67 mm tl) were the dominant piscine prey of summer flounder (n=95, 252-648 mm tl) collected in trammel nets. we observed a temporal shift in summer flounder diets from sand shrimp (crangon septemspinosa) and winter flound ... | 2000 | 10958899 |
| description of gyrodactylus notatae n. sp. (monogenea: gyrodactylidae) from menidia menidia (l.) (actinopterygii: atherinidae) in nova scotia, canada. | gyrodactylus notatae n. sp. (monogenea: gyrodactylidae) is described from the fins and gills of the atlantic silverside menidia menidia (l.) (atherinidae) inhabiting the brackish water of lawrencetown lake, nova scotia, canada. g. notatae n. sp. is the first monogenean to be reported from m. menidia. it is characterised by having stout hamuli, a ventral bar with small anterolateral processes and a linguiform membrane, a cylindrical dorsal bar, a male copulatory organ (mco) with a single large an ... | 2009 | 19633928 |
| morphological and behavioral antipredatory adaptations of decapod zoeae. | zoeae of some species of estuarine decapods are retained in the estuary throughout development while others are exported into nearshore coastal waters. the horizontal migrations of decapod zoeae to coastal waters may have evolved to reduce the probability of encountering planktivorous fishes which are most abundant in the estuary. if so, then the morphological vulnerability of zoeae to fish predation should be inversely related to the number of predators occurring where they develop. six species ... | 1987 | 28311521 |
| occurrence of cis-9,10-methylenehexadecanoic and cis-9, 10-methyleneoctadecanoic acids in the lipids of immature and mature fundulus heteroclitus (l.), and in roe. | analysis of saturated fatty acids in the mummichog fundulus heteroclitus (l.) by argentation chromatography and open-tubular gas-liquid chromatography detected cyclopropanoid fatty acids as well as all of the anticipated saturated fatty acids, including a variety of branched-chain saturated fatty acids previously found in fish. cyclopropanoid fatty acids were identified in juveniles, male and female bodies, and roe. when the levels of these acids in eviscerated male and female bodies were compar ... | 1983 | 6617160 |
