Abstract
Supplementary feeding may influence the water quality parameters, especially the
productivity. Productivity is one of the principal water quality parameters that determine
fish production. An experiment was carried out to evaluate the relationship between
productivity and growth in Etroplus suratensis fed diet containing Nutripro-Aqua, a commercial
growth promoter. Fishes were cultured in cement tanks for 180 days and the growth and
productivity were monitored periodically. Nutripro-Aqua was administered through a
standard pelletized feed with 40% protein at four dosages, 0, 8, 9.5 and 11%. Productivity
and growth of fishes were found to be significantly high in 11% treatment, which indicates
the influence of the pond productivity on growth of fishes.
