Abstract

The assessment of the marine fishery was investigated in the Chaungtha Coastal Area for ten months from November 2023 to August 2024. In this study area, seven different types of fishing gear have been recorded, such as bottom set gillnets, purse seines, beach seines, drift gillnets, longlines, dive fishing, and trap fishing. Beach seine was the most efficient fishing gear (27.63%) of species composition, followed by purse seine (25.66%) and bottom set gillnet (22.37%), while trap fishing was the least efficient (0.66%). Sardinella forms the significant component of landings (16.20%), followed by groupers (14.77%) and yellow pike conger (13.58%). The mean catch per unit effort (catch/unit effort/day) was 3.55 kg, and the range was 0.15- 6.47 kg, recorded in July 2024 and November 2023. The highest total catches, 2199.35 kg, were recorded in November 2023, followed by 1843.13 kg in January and 1590.3 kg in March 2024, while 50.18 kg was the least caught in July 2024. The biomass of marine fishes ranged from 7.91 mt to 723.70 mt. The mean biomass was recorded at 205.09 mt in the present study.
