EFFECT OF STOCKING DENSITY ON GROWTH AND SURVIVAL RATE OF LABEO ROHITA (HAMILTON) FED WITH FORMULATED FEED

Abstract

To study the effect of stocking density on growth and survival rate of Labeo rohita, a three month experiment was conducted during July to September 2009. Three different stocking densities 10, 15 and 20 Fish/ aquaria were assigned as treatment I, II and III respectively. The experimental fish were fed with formulated feed 35% (gross protein). The result of the density experiment showed significantly (p<0.05) highest growth and survival rate in treatment II (15 fish/ aquaria). While significantly lowest growth and survival was recorded in treatment III. The water quality parameters and their monthly fluctuations recorded throughout the study period were found with in the suitable ranges for the fish culture.
