Fish catch rate and fishing efficiency of trawling off Raigad coast of Maharashtra, India

Abstract

The present study deals with the fish catch discard rate and fishing efficiency of commercial multi-day and single-day trawlers operated along the Raigad coast of Maharashtra. The trawlers from Raigad coast carried out fishing operations between 180 10’ 00” N to 190 20’ 00” N latitude and 720 45’ 00” E to 730 30’ 00” E longitude in the depth range between 12 to 52m. The study revealed that the average catch was 32.65 kg/h and 32.09 kg/h with an average discard of 7.63 kg/h and 4.02 kg/h for multi-day and single-day trawler respectively. The t-Test performed on fish catch and discards of multi-day and single-day trawlers did not reveal a statistically significant difference (p>0.05) in a fish catch (kg/h) but in the case of multi-day trawlers, there was a statistically significant difference (p
