The quantity of production of fish seeds for water bodies was to the tune of 32 million which was quite low as compared to the demand. To make up this deficiency, the NEC had set up a fish seed production farm in Tripura, a fish seed farm at Thizama in Nagaland and a high altitude fish seed farm in Arunachal Pradesh. To give a further boost to the production of fish seed, a pituitary gland bank was also set up in Tripura. All these four projects were set up to bridge the gap between demand and supply.

Fish production was hampered also due to the growth of weeds, specially water hyacinth. For this purpose, the NEC had taken up a project for clearing of 400 hectares in Takmu commercial fishery lake in Manipur and this project showed remarkable increase in fish production.

The NEC had also sponsored studies on the hydro-biological conditions of water bodies in Meghalaya and Assam, through the agencies of the NEHU and the Guwahati University, respectively. A research project on the economic uses of water hyacinth was also conducted through the Guwahati University.
