Abstract: Based on the production of 3 fishing vessels, the weight of factors including gross tonnage, power of the main engine, operating days and underwater light power that affect the catching capability of light-purse seine vessels in Zhoushan waters were analyzed with AHP and the weights of the factors were defined according to their importance and evaluation model of factors affecting catching capability of light-purse seine vessels was established. The results show that the weight score for gross tonnage,power of the main engine, operating days and the underwater light power is 0.461 2, 0.342 4, 0. 1371 and 0.0594 respectively.

Key words: AHP, light-purse seine vessel, fishing capability, affecting factors, weight
