A study was carried out in restored South West Lake and non-restored East Lake, of Beira lake with the objective of determining the species composition, density and distribution of zooplankton. Water was sampled from the surface and at a depth of 1 m, from February to March, 2005 between 0900-1130 h. Three rotifers species; Brachinonus calyciflorus, Keratella tropica, Filinia sp., three cladoce...

The present study was carried out on the seasonal abundance and diversity of zooplankton in a semi- intensive prawn farm of Bagerhat district from July to December, 2008. Plankton samples were collected by conical shaped monofilament nylon net (Plankton net) and Lugol's solution was used for preservation. The zooplankton abundance was influenced by physico-chemical factors. During the study per...

The nematode communities of Antarctica are considered simple. The few species present are well adapted to the harsh conditions and often endemic to Antarctica. Knowledge of Antarctic terrestrial ecosystems is increasing rapidly, but nematode communities remain to be explored in large parts of Antarctica. In soil samples collected at Byers Peninsula (Antarctic Specially Protected Area No. 126), ...

The TOR kinase pathway is central in modulating aging in a variety of animal models. The target of rapamycin (TOR) integrates a complex network of signals from growth conditions, nutrient availability, energy status, and physiological stresses and matches an organism's growth rate to the resource environment. Important remaining problems are the identification of the pathways that interact with...

The effect of rotifers, Brachionus rotundiformis (S-type), fed three different diets: A (rotifer fed Nannochloropsis oculata), B (rotifer fed N. oculata and baker's yeast, 1:1), and C (rotifer fed N. oculata and baker's yeast, 1:1, and enriched with Selcoregister mark or target), was evaluated based on the survival, growth and swim bladder inflation rate of fat snook larvae. Rotifers of treatme...

Survival of larvae of mud crab, Scylla serrata (Forsskal, 1775) is a persistent issue in the field of induced breeding of the species. A preliminary study was conducted on feeding regimes of laboratory reared larvae and juveniles of S. serrata. The results showed that the survival of the larvae fed with green water alone or green water with plankton and feed was not significantly different from...

The study of sexual reproductive behavior supported by ultrastructural evidence is important in rotifers to describe differences among potential cryptic species. In this research, the morphology of the rotifer Brachionus bidentatus is described at the ultrastructural level, using electronic microscopy, together with a brief description and discussion of its sexual reproductive behavior. The cha...

this study was carried out to evaluate the effect of probiotic (bacillus latrospores and bacillus licheniformis) on growth and survival of silver carp larvae (hypophthalmichthys molitrix). rotifers (brachionus plicatilis) were used as live prey vehicle for probiotic transport. they were cultured in sea water with 15 ppt salinity and nannochloropsis oculata microalgae was used as feed. five trea...

This study assessed horizontal and vertical distribution abundance of zooplankton community in water samples collected from 26 stations at a depth 0 to 250 m the northern Bay Bengal. A total 55 species were identified where Copepod was 72.41% Ciliophora 8.62%. Among Copepod, 48%, 40% 12% Calanoid, Cyclopoid Harpacticoid respectively. also found 2 Decapod, Rotifer, Cladocera, 1 Chaetognatha Stom...
