Abstract

A demonstrative cage culture of commercially important fish species was carried out at Gelabeel in Golaghat District and Moridikhow beel in Sivasagar District of upper Assam during 2013-14 as a technology for enhancement of fish production as well as an alternative source of livelihood for the rural people. Five carp species viz., Labeo rohita, L, calbasu, L. gonius, Catla catla and Cirrhinus mrigala were taken as candidate species for 3 months trial culture. Rice bran and mustard oil cake blended in 1:1 ratio was given in pelleted form daily @3-5% of aggregate body weight of fry. Percentage of fish recovery from a 2m3 after 90 days was 71.67 in first trial and 86.67 in second trials. The average growth increment for about 3 months was 114.8mm and 131.6g and the average growth increment per month was 38.26mm and 43.86g. On an average, a profit of Rs 840/- per cage was recorded in 3 months. At Moridikhow also, all the species showed encouraging growth However, poaching is a major problem and community participation for development of cage culture has been suggested.
