| distribution of po-210 in two species of predatory marine fish from the brazilian coast. | polonium-210 ((210)po) concentration was quantified in the muscle tissue and organs of two predatory marine fishes (genypterus brasiliensis and cynoscion microlepidotus) from cabo frio, rio de janeiro, brazil. the species c. microlepidotus, a benthic carnivore, registered higher (210)po in its tissue. the organs associated with digestion displayed the maximum radionuclide compared with other organs. the average activity was 2 mbq kg(-1) for g. brasiliensis and it was 6 mbq kg(-1) for c. microlep ... | 2014 | 24334195 |
| community ecology of the metazoan parasites of pink cusk-eel, genypterus brasiliensis (osteichthyes: ophidiidae), from the coastal zone of the state of rio de janeiro, brazil. | fifty-five specimens of pink cusk-eel, genypterus brasiliensis regan, 1903 (osteichthyes: ophidiidae) collected from the coastal zone of the state of rio de janeiro, brazil (approx. 21-23 degrees s, 41-45 degrees w), from september 2000 to january 2001, were necropsied to study their parasites. all fish were parasitized by one or more metazoan. fourteen species of parasites were collected. g. brasiliensis is a new host record for nine parasite species. the larval stages of cestodes and the nemat ... | 2002 | 12219136 |
| pseudolernentoma brasiliensis n. g., n. sp. (copepoda: poecilostomatoida: chondracanthidae) parasitic on genypterus brasiliensis (osteichthyes: ophidiidae) from off the state of rio de janeiro, brazil. | pseudolernentoma, a new chondracanthid genus was proposed to accommodate pseudolernentoma brasiliensis n. g., n. sp., parasitic on the pink cusk-eel genypterus brasiliensis regan, from off the coast of rio de janeiro, brazil. the new genus can be differentiated from the other genera of the chondracanthidae by the presence of an inflated head with lateral expansions and anteroventral bifurcate processes on the trunk. | 2003 | 14707505 |
