A Study on the performance of small holder carp hatcheries in Khordha district of Odisha State, India

摘要

Timely supply of quality fish seed is crucial to the development of freshwater aquaculture in India. The hatcheries are the predominant suppliers of fish seed which are managed in both government and private sectors. A diverse range of the fish seed qualities is produced by these hatcheries. To produce quality seed, the hatcheries must be equipped with adequate technical knowhow, resources and facilities. To create centres of quality seed production, Krishi Vigyan Kendra (KVK)-Khordha under Central Institute of Freshwater Aquaculture (CIFA) has established five carp hatcheries in Khordha district during 1985-2013. These hatcheries contribute 63.78 per cent of total fish seed supply in the district. The present paper is based on the performance evaluation study conducted on these five hatcheries. The results indicate that majority of hatcheries possess adequate resources of ponds and other facilities to achieve their potential in fish seed production. The average seed production is found to be 6.2 crores spawn, 26.40 lakh fry, 520 kg fingerlings, and 2220 kg yearlings with average operation of 12 cycles/yr. The hatcheries have created employment opportunities of 168 man days with B: C ratio of 2.79.
