dc.description.abstract | Vellayani Lake is the second largest freshwater lake in the state providing freshwater food fishes in addition to being a major drinking water source in Trivandrum District. Owing to the declining fish catches in the lake, Agency for Development of Aquaculture, Kerala (ADAK) introduced juveniles of nonnative Indian Major Carps Catla (Catla catla) and Rohu (Labeo rohita) in the lake as a part of fish stock enhancement. The introduced fishes grew well in the conditions of the lake and started appearing in commercial catches within six months after stocking, resulting in a considerable increase in the capture production. The 150 odd fishermen depending on the lake for livelihood mostly operated gillnets (Pattuvala) in the night. The increase in catch with large fishes motivated some of the fishermen to use locally designed encircling gill nets (Vaanguvala) in the day time to increase the efficiency of operations. A comparative analysis of catch and operational parameters of Pattuvala and Vaanguvala were carried out by surveying the fishermen operating these gears in Vellayani Lake. Rohu forms the major catch in Vaanguvala and catla was the major catch in Pattuvala. The CPUE of Pattuvala was very low compared to the Vanguvala. The average area of the webbing of Pattuvala was 258.3sq.m and that of Vaanguvala was 350 sq.m. The average catch of Rohu in Vaangula was 10.49±0.77 Kg and the catch of catla in Pattuvala was 3.31±0.27 Kg. | en_US |
