abstract
Cage culture is the most efficient potential system of the farming practices, to utilize the untapped water bodies. Here, an ideal species selection is imperative to achieve the better growth that ensure to achieve higher economic return. Therefore, present study was aimed to evaluate the growth and survival of amur carp and pangasius at floating cages at Stanley reservoir, Tamil Nadu. The larval fish of carp and pangasius were obtained from the local hatcheries, and socked into 12 HDPE cages (5 x 5 x 4 m) at stocking density of 50 m^-3 (9832 numbers) and 40m^-3 (14158 number) respectively. The estimated specific growth was of 2.063% day^–-1 for amur carp and 2.278% day^–-1for pangasius and the survival rate was about 50% for the both the species. Water quality parameters were within limited of fish culture as recommended BIS/ICMR. The data of the study suggesting that both the species are ideal for culture and not affected the water quality parameters remarkably. It is advocates that we needed to consider the local price of fish to obtain the high economics return.
