The supply of seafood materials for processing has declined significantly as a result of continued flooding in the delta in the last few months in the Cuu Long (Mekong) Delta.
In Kien Giang Province, for example, the volume of rainfall and floods has changed the environment around shrimp-farming ponds, and as a result, many shrimp have died.
Nguyen Danh Hien, director of Minh Phu Aquaculture Company, said he had expected his 100ha-farm would yield 1,500 tonnes of shrimp, as in previous farming crops, but the actual yield this year was only 500 tonnes.
He said flood waters had dissolved the salinity in ponds, causing shrimp to die.
Other farms in the province have had a low yield as well.
The price of shrimp used as raw materials for seafood processing has risen to VND270,000, or about VND14,000 over the last crop.
