abstract={The present study was conducted under two experiments to evaluate the effects of different feeds on larval (experiment-1) and fry rearing (experiment-2) of <i>Labeo bata</i> fish. Experiment-1 was conducted in 9 bowls under three treatments each with 3 replications (T<SUB>1</SUB>, T<SUB>2</SUB>, and T<SUB>3</SUB>). Fish larvae in T<SUB>1</SUB> were fed with plankton, T<SUB>2</SUB> with commercial feed and T<SUB>3</SUB> with laboratory prepared feed. On the other hand, six ponds were divided into three treatments (T<SUB>1</SUB>, T<SUB>2</SUB> and T<SUB>3</SUB>) each with two replications in experiment-2. Fish meal was used in T<SUB>1</SUB>, wheat bran in T<SUB>2</SUB> and laboratory prepared feed in T<SUB>3</SUB>. Results in experiment-1 revealed maximum length gain in T<SUB>1</SUB><SUB> </SUB>(1.56¡À0.69) (cm) which was significantly (<i>P</i>&lt;0.05) higher than that of T<SUB>2</SUB> (0.64¡À0.34) cm and T<SUB>3 </SUB>(0.98¡À0.29) cm. Furthermore, highest specific growth rates (SGR) were found as (2.85¡À0.27)%, (1.55¡À0.11)% and (1.99¡À0.15)% in T<SUB>1</SUB>, T<SUB>2</SUB> and T<SUB>3</SUB>, respectively. On the basis of growth performance, live food (plankton) showed the highest growth performance in case of larval rearing of bata. On contrary, experiment-2 revealed the mean maximum length gain of bata fry in T<SUB>1 </SUB>(3.76¡À0.05) cm significantly (<i>P</i>&lt;0.05) higher than that of T<SUB>2</SUB> (2.85¡À0.02) cm and T<SUB>3 </SUB>(2.56¡À0.01) cm. In this case, SGR was found in T<SUB>1</SUB> (0.91¡À0.01)% followed by T<SUB>2</SUB> (0.72¡À0.13)% and T<SUB>3</SUB> (0.65¡À0.15)%. Use of fish meal showed best growth performance during bata fry rearing in terms of growth performance. However, the survival rates were low in both the experiments; therefore further detail and intensive research are highly suggested.},
