Effects of stocking density on growth performance and survival of three male morphotypes in all-male culture of Macrobrachium rosenbergii (De Man)
A study was conducted to appraise the effect of different stocking densities on three male morphotypes named blue claw (BC), orange claw (OC) and small male (SM) at harvest in all-male culture and to assess the growth performance of BC, OC and SM in each isolated culture. Trials involving three stocking densities of all-male prawn viz., 20, 30 and 40 juvenile m-2 were carried out in...

متن کاملA novel two-step procedure for mass production of all-male populations of the giant freshwater prawn Macrobrachium rosenbergii
Males of the giant freshwater prawn Macrobrachium rosenbergii grow faster and reach higher weights at harvest than females a fact which makes the culture of all-male populations desirable. All-male populations were produced by mating sex-reversed males, i.e., neofemales, with normal males. Neofemales capable of mating and spawning were produced by removal of the androgenic gland (AG) from immat...
متن کاملStocking densities for nursery phase culture of the freshwater prawn Macrobrachium rosenbergii in cages
Effect of stocking density on growth, biomass increase and survival of postlarvae of Macrobrachium rosenbergii were evaluated in cages fixed inside an earthen pond. In the primary Ž . nursery phase, newly metamorphosed postlarvae PL were stocked for 20 days at densities of 2, y1 Ž . 4, 6, 8 and 10 PLs l . In the secondary phase 60 days , the densities tested were 100, 200, 300, 400, 600 and 800...
متن کاملClarias and Tilapia Interaction in Polyculture
Experiments were conducted to assess the effects of polyculture on tilapia growth and to evaluate African catfish (Clarias gariepinus) as a predator control for unwanted tilapia offspring in a polyculture system. Three treatments were tested using nine 200 m earthen ponds. Ponds were stocked with male tilapia in treatment 1 (Tl), mixed sex tilapia in treatment 2 (T2), and mixed sex tilapia and ...
