ResumoThis study was conducted to determine current status of fisheries and potential aquaculture of echinoidea sea urchin in the South west sea, Kien Giang, Viet Nam. Survey data were collected from a questionnaire-based interview of key informants and 34 fishermen interviews and live specimences were collected from the ocean then transferred to the wetlab, College of Aquaculture and Fisheries, Can Tho University for morphology and taxonomy analysis. The results showed that there are 5 main sea urchin species including collected sea urchin (Tripneustes gratilla), banded sea urchin (Echinotrix calamaris), black sea urchin (Diadema setosum), white salmacis urchin (Salmacis sphaeroides) and Salmacis dussumieri). Among those species collected sea urchin, banded sea urchin and black sea urchin are highly commercial value market. Fishery sea urchin has begun in 2014, but total yield was high (about 36,000 ind./day), with an average of 155±188 ind./household/day. Total revenue for each fishing trip is low about 0.12 million VND/household and net profit is highly fluctuated (0.15-6.0 million VND/household/day), and return on equity ratio is 23. Currently, the exploitation of sea urchin in Kien Giang has faced many difficulties in terms of weather, unstable consumption markets and declining resources. However, protential aquaculture of sea urchin is very high due to large area on the water surface (206 km coastline) and high economic value of sea urchin.
