Đánh giá hoạt động khai thác thủy sản ở Đồng bằng sông Cửu Long

Abstract

A study of fishing activities was conducted from July to December 2017 in coastal provinces of the Mekong Delta. Results show that the gill nets, trawl nets, bag nets, and cage traps were main fishing gears and had highest number of fishing boats and yields. All of fishing gears can capture whole year round. Gill nets had largest scale, but the yield of trawlers was highest. Gill nets were most effective with highest profit achieved (298 million VND per year). Trawlers had highest yield (20.42 tons/year), but they had highest ratio of trash fish (38.4%) and lowest benefit ratio (0.45 times). Although the bag nets had highest benefit ratio (1.41 times), they had lowest yield (7.17 tons/year) and highest ratios of trash fish so they affected fisheries resources. Cage traps had highest ratio of trash fish (23.8%). For the sustainable development of fishing, management of fisheries resources should be promoted, supporting fishermen to access low interest rates to invest in capture production, and training them to use advanced fishing gear to increase their fishing efficiency.
