Analysis of Technical and Financial Aspects of Suminoe oyster (Crassostrea rivularis) Esturial Cage Culture in Bac Lieu Province
Abstract
The study was performed to analyse the technical and financial aspects of Suminoe oyster (Crassostrea rivularis) cultured in cage in Bac Lieu Province during August to December 2014. The results showed that Suminoe oysters were cultured throughout the year, mostly in January and February lunar calendar, and its culture density was 239 ± 29.93 individual/m2; the average size of breeder was 103 ± 3.45 gram/ individual. After 8-10 months of culture, the average production was 71.62 ± 7.20 kg/m2, and the survival rate was 90 ± 1.16%. The average total cost and
income was 384 million and 466 million Viet Nam dong per crop, respectively, with high benefit-cost ratio (1.21). The culture system had many advantages, including good natural conditions, simple farming techniques, easy to manage, and low disease incidence. The main disadvantages include full dependence on the natural resources, lack of funds for expanding the culture scales, solely domestic consumption. The study provides basic information for development of the Suminoe oyster culture industry in Bac Lieu Province in future.
