Summary: 

A fry to fingerling production demonstration was conducted at Thirumaniari, Tiruvaroor District, Tamil Nadu, India to demonstrate the growth of rohu carp (Labeo rohita) using ASA-IM pond culture methodologies and feeds. Three earthen ponds were used in the demonstration. Rohu carp fry were stocked in one pond (named Stage 1) at five million fry per hectare and cultured using the ASA-IM recommended pond maintenance techniques and a green water system for two weeks. Rohu carp were then transferred from the Stage 1 pond to two Stage 2 ponds and cultured using the feed-based ASA-IM technology with 41/11 and 36/7 soy based feeds. The rohu were stocked at an average stocking rate of about 500,000 and the fry grew from 1 g to 9.7 g in 50 days and yielded an average production of 3,439 kg/ha with 94% average survival. This was the first project of this type in India and Stage 1 results were disappointing, with a low survival rate (<25%) that may be partially attributed to an inadequate maintenance of the plankton bloom, the sole source of nutrition for the fry, and possible entrance of fry eating organisms such as frogs and water breathing insects.
