Conference of planning whiteleg shrimp farming

On April 26th in Soc Trang Province, The MARD, Directorate of Fisheries in conjunction with Soc Trang People’s Committee celebrated a conference of planning whiteleg shrimp (vannamei) farming.

In Vietnam, whiteleg shrimp, originated from South America, was farmed for testing in 2002. After a trial period, in 2008, MARD laid down whiteleg shrimp farming development  as a policy.

Accordingly, Southern provinces were allowed to farm whiteleg shrimp but they must ensure planning area, irrigation systems, infrastructure for intensive shrimp farming. Particularly, the coastal provinces from Binh Thuan to Quang Ninh were allowed to raise in local areas.

In 2002, whiteleg shrimp farming area throughout the country reached 1,710 ha with production of 10,000 MT. In 2010, domestic farming area increased to over 25,300 ha, mainly in central and northern provinces, accounting for 17,960 ha, equivalent to 72 percent of national whiteleg shrimp farming area. Some Mekong Delta provinces are developing  whiteleg shrimp farming in narrow area.

According to development orientation reports of whiteleg shrimp farming of Department of Aquaculture (DoA), whiteleg shrimp live in the middle layer. Whiteled shrimp do not bury themselves under mud like black tiger shrimp, their shells are not covered by moss, so they can be raised in high density (100 – 120 pieces per square meter).  A whiteleg shrimp crop  only lasts 80 – 90 days, so there may be 3 – 4 crops per year. Average productivity reaches 10 MT per hectare per crop or even 20 MT per hectare per crop in some other regions. In the process of raising, whiteleg shrimp are at risk of catching some diseases like those on black tiger shrimp. Besides, whiteleg shrimp can get Taura (Taura syndrome) which leads to shrimp’s mass mortality, spreads to black tiger shrimp and causes loss to the shrimp farming industry. Therefore, whiteleg shrimp farming area planning must be considered, common irrigation systems must be invested, food safety and hygiene must be ensured in ponds, which are conditions for sustainable development.

At the conference, many participants proposed competent authorities to strengthen investment in infrastructure, rapidly transfer technical advances in seed production, tightly manage broodstock source, especially stocksimported from China, develop models as well as apply some policiesencouraging development of whiteleg shrimp farming … This helps to guide farmers, ease current difficulties, promote aquaculture industry in the countryin general and the Mekong Delta region in particular.
