Bioconcentration and Acute Intoxication of Brazilian Freshwater Fishes by the Methyl Parathion Organophosphate Pesticide [PDF]
Three species of freshwater Brazilian fishes (pacu, Piaractus mesopotamicus; piavussu, Leporinus macrocephalus, and curimbatá, Prochilodus lineatus) were exposed to an acute dose of 5 ppm methyl parathion organophosphate pesticide. Three to five individuals per species were exposed, one at a time, to 40 liters tap water spiked with Folidol 600 ...

Structural analysis of the embryonic development inBrycon cephalus(Günther, 1869) [PDF]
SummaryThe embryogenesis ofBrycon cephaluswas established in seven stages: zygote, cleavage, blastula, gastrula, segmentation, larval and hatching, in an incubation period of 11 h (26°C). The zygote phase was observed directly after fertilization and egg hydration.

Abstract For the evaluation of the effects of the transport density of pirarucu juveniles, 210 juvenile pirarucus, Arapaima gigas (488 ± 26.5 g) were randomly distributed in 12 plastic boxes at transport densities of 98, 146, 195, and 244 g L−1. The transport was carried out on a paved highway for 4 h, and at the end of the transport, all were returned

Abstract Increasing the number of fish stocked might optimize the efficiency of intensive aquaculture systems however at the same time might have a negative impact on fish welfare and growth parameters. In the current study, three different stocking densities were evaluated in duplicated tanks to investigate the effect of different stocking densities ...
