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 ...
متن کاملImpacts of inclusion of column feeder rohu (Labeo rohita) at different stocking densities on growth, production and environment in freshwater prawn-carp-mola polyculture system
The research investigated the impacts of inclusion of column feeder rohu (Labeo rohita) on growth and production in freshwater prawn-carp-mola polyculture system for a period of 172 days. Four stocking densities of Rohu were maintained as 500, 1,000, 1,500 and 2,000 ha -1 in treatment R500, R1000, R1500 and R2000, respectively in triplicates. All ponds each 120 m 2 were stocked with juvenile fr...
