- Abstract
The influence of different stocking density on the rearing of fish, Channa punctatus in terms of weight gain (grams) and survival ratio (%) was investigated. Present trial was conducted for a period of 90 days in cemented tanks at University of Sindh, Jamshoro, Pakistan. Different stocking densities were determined such as 10, 15, and 20 fish/m2were selected and placed in different treatments (I-III) with two replicates Fish were fed all parts of chicken (APC) with 10% of their body weight. The results of the growth trial indicated moderate variation among the treatments that, 10 fish/m2in T-I exhibited maximum growth (64.6 g) with 100% survival ratio as compared to other treatment (II and III), 15 fish/m2 (35.0 g with 90% survival) and 20 fish/m2 (16.4 g with 80% survival), respectively. The water quality parameters were monitored on fortnightly basis, such as temperature values were found within optimal range of 26.8 to 30.6oC, pH (7.3 to 7.5), oxygen (4.0 to 4.8mg/l), alkalinity (149 to 180mh/l), nitrate (0.17 to 0.18mg/l) and ammonia from 0.35 to 0.55ug/dLumol/litre. Theresults of the current study concluded that Channa punctatus have a preference to living in a small community than large schooling and could be reared 10/fish/m2 was found to be suitable density for growth and survival in cemented cisterns. Present study plays an important role for culturing and rearing of native snakehead species.
