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

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
