Abstract

It is important to determine suitable water depth for larval rearing to reduce the cost of production in aquaculture because using more water means paying more money. An experiment was conducted to study the effects of different water depth on growth and survival rate of Patin, Pangasius hypophthalmus larvae. Three different water depths with triplicate were used which were low (15cm), medium (35cm) and high (55cm). All the larvae were reared in 1 ton tarue The results showed that 35cm water depth had the highest mean survival rate and growth rate which was 67.26% of survival rate and 1.427 cm of mean total length, followed by in 55cm water depth which was 59.43% of survival rate and 1.398cm of mean total length and lastly in 15cm water depth with 57.04% of survival rate and 1.369cm of mean total length. However, there were no significant difference (P>0.05) when compared to all treatment when analyzed with one-way ANOVA. This study suggested to rear the Patin larvae in 15cm water depth from economic prospective to produce better and economically viable fish since water depth will not affected the growth and survival rate of the larvae.
