Use of Brewer’s Yeast Saccharomyces cerevisiae as Growth Promoter in Giant Freshwater Prawn (Macrobrachium rosenbergii de Man) Post Larvae
A feeding trial was conducted for 75 days to study the effects of live brewer’s yeast (Saccharomyces cerevisiae) on growth and body composition in post larvae of the giant freshwater prawn, Macrobrachium rosenbergii (de Man). Five diets were formulated containing optimum protein level of 35.24±0.04. These experimental feeds were supplemented with 0.0% (control diet), 0.1%, 0.2%, 0.5% and 1.0% l...
متن کاملVitellogenesis during the ovarian development in freshwater female prawn Macrobrachium rosenbergii (De Man)
In the present investigation, vitellogenesis during ovarian development in the freshwater prawn Macrobrachium rosenbergii was assessed. Ovarian development was classified into five stages based on size, colour and texture of ovary. Interestingly, histological results clearly indicate that the oocyte development gradually increased from stages I to V based on the yolk material accumulation. Besi...
متن کاملIsolation of a pathogenic strain of Vibrio alginolyticus from necrotic larvae of Macrobrachium rosenbergii (de Man).
Giant freshwater prawn, Macrobrachium rosenbergii (de Man), is an important commercial species with considerable export value, ideal for cultivation under low saline conditions and in freshwater zones (Kurup 1994). However, despite more than a decade of research on its larval production systems, vibriosis still hampers seed production resulting in high mortality rates. Among the different speci...
متن کاملInfluence of short term exposure of TBT on the male reproductive activity in freshwater prawn Macrobrachium rosenbergii (De Man).
In the present study, the effect of tributyltin (TBT) on the histopathological and hormonal changes during spermatogenesis in freshwater prawn Macrobrachium rosenbergii was documented. Three experimental concentrations such as 10, 100 and 1,000 ng/L were selected and exposed to prawns for 45 days. After TBT exposure, the reproductive activities like sperm count and sperm length were decreased w...
متن کاملEffects of different types of artificial substrates on nursery production of freshwater prawn, Macrobrachium rosenbergii (de Man) in recirculatory system
An experiment was conducted for two months in a recirculatory system consisting 12 glass aquaria (size 41× 41 × 46 cm) to evaluate the effects of substrates on the growth and survival of Macribrachium rosenbergii postlarvae (PL). Treatment T1 having no substrate was considered as the control. Treatment T2 contained pieces of hollow PVC pipe, treatment T3 and T4 were provided with high density p...
