Abstract

The effect of food ration on growth and survival of juveniles of Platy fish, Xiphophorus maculatus was investigated. The juveniles Platy fish were submitted to six weeks growth trial. They were fed with increasing levels of food ration of 2, 4, 6 and 8 % body weight in the form of formulated dry pellets to study the growth and survival under laboratory conditions. The growth (123.83 ± 0.64 of weight and 191.98 ± 1.55 of length) and survival rate (98 ± 1.01) were found to be highest at 8% of food ration. Specific growth rate was also recorded highest in 8% food ration at the end of the experiment. The data revealed that for juveniles of Platy fish, Xiphophorus maculatus, food ration of 8 % body weight is best to achieve maximum growth.
