Mass culture of the rotifer Brachionus plicatilis and its evaluation as a food for larval anchovies
Growth rates of anchovy larvae, Engraulis mordax, reared for 19 days under constant environmental conditions on a diet of laboratory-cultured organisms, exceeded the growth rates of anchovies fed on a diet of wild plankton. The rotifer Brachionus plicatilis was found to be a nutritious food source when fed to the larvae in concentrations of 10 to 20/ml and in combination with the dinoflagellate...
متن کاملExternal Morphological Development of Post-larvae and Juveniles of Red Seabream, Pagrus major
On the 15 days after hatching, the larvae was 4.24-5.10 mm (mean 4.66±2.18 mm) in total length, and the fins of the membrane started to develop into a fan shape and the melanophore was deposited upper the alimentary canal of the abdomen and on the bladder. At 35 days after hatching, the post-larvae formed a branch-shaped melanophore on the head part with a total length of 6.98-12.5 (mean 9.35±1...
متن کاملThe effect of food deprivation on the fatty acid and lipid profile of red seabream (Pagrus major) larvae.
Under conditions of food deprivation the lipid fraction of red seabream (Pagrus major) larvae shows patterns of conservation or loss in the profile of fatty acids and lipids. These changes were used for qualitative formulation of the dietary requirements of this species. Red seabream larvae were deprived of food for 5 d after hatching. Their lipid was extracted, weighed and analysed by gas-liqu...
متن کاملAnalysis of Expressed Sequence Tags of the Cyclically Parthenogenetic Rotifer Brachionus plicatilis
BACKGROUND Rotifers are among the most common non-arthropod animals and are the most experimentally tractable members of the basal assemblage of metazoan phyla known as Gnathifera. The monogonont rotifer Brachionus plicatilis is a developing model system for ecotoxicology, aquatic ecology, cryptic speciation, and the evolution of sex, and is an important food source for finfish aquaculture. How...
متن کاملProduction of the rotifer Brachionus plicatilis (Ploimida: Brachionidae) in a Brazilian coastal lagoon.
Secondary production, density and biomass fluctuations, and some reproductive aspects of the rotifer Brachionus plicatilis were studied weekly for two years in a Brazilian coastal lagoon. Food (and secondarily temperature) seemed to be the main factor involved in the summer increments. In the first summer, a mass mortality of fish caused changes in the phytoplankton, which switched from the dom...
