Abstract

In the polyethylene-fiim-lined ponds at Calicut, Etroplus suratensis has yielded an Instataneous growth rate varying between 0.01168 and 0.02262 and spawned comparably with those cultured in other systems, though the production and survival rates were not equal to the latter, indicating that the ponds can, with proper monitoring, be used, besides as a culture system, as an effective hatchery system for raising the seed of the fish.
