摘要

Comparative economic efficiency of purse seiners, trawlers and drift gill netters operating alongudKerala Coast was studied from 1982 to 1986. The gross income aid net income per unit per day of operation, rate of returns, returns to labour, fuel efficiency and pay-back period have been worked out for all the 3 types of units. These fishing units do not corapste eich other and their catch compositions are different. However, the evaluationudof their comparatie economic efficiency is essential for formulating credit policy and developmentudplans. Initial investment on a new unit showed considerable increase over the years for all the 3 typesudof fishing gears studied. The purchase price of a purse seine craft and gear amounting to about Rs. 7udlakhs in 1982 increased to Rs. 12 lakhs in 1986. Fuel cost increased due to enhancement in price as welludas in utilisation level. Neverthelois, the average gross revenue per imit per day of operationudof a purse seiner continuously increased from about Rs. 5000 in 1982 to about Rs. 12,000 in 1986.udFor trawlers it increased from Rs. 826 in 1982 to Rs. 2,250 in 1986 and with respect to drift gill nets itudworked out to Rs. 606 in 1982 and Rs. 1,227 in 1986.
