Abstract: 

The present experiment evaluated the effect of density on weight gain and feed conversion ratio (FCR) for rainbow trout in concrete ponds, with use of aeration and well water. Density rates were 44, 62, 76 and 95 Fish/m2, with an average weight 18±3 gr. and two replicates for 135 days. Aeration carried out by an air blower set into the water from ponds floor. The results showed, 44 (as control density) and 62 Fish/m2 significantly (p<0.05) caused higher weight gain (167.6 and 165.25 g/fish respectively) and specific growth rate than other densities and also, better feed conversion ratio. Increasing density caused more mortality. However, under these circumstances the density of 62 Fish/m2 is recommended.
