Update: November, 19/2012 - 14:50

CAN THO (VNS)– About 78,700ha of shrimps in the Cuu Long (Mekong) Delta have died in the past seven months, as many deaths as the entire previous year, the Ministry of Agriculture and Rural Development has reported.

Most of the deaths were in Soc Trang, Ca Mau, Tra Vinh, Kien Giang and Bac Lieu provinces, the ministry said.

About 30,000ha of shrimps died from acute liver and pancreas caseation while more than 40,000ha died for other diseases and polluted water.

The total loss was estimated to cost nearly VND6 trillion (US$285 million).

The ministry has asked the aqua product sector in the delta to improve irrigation systems, control waste water and manage the selection process, culling substandard shrimps.

Local authorities asked farmers not to use chemicals and pesticides in or near shrimp ponds, especially substances containing Cypermethrin and Deltamethrin as they killed shrimps and remained in the water.

Provincial inspectors were required to check aquatic product medicine and food trading enterprises to detect and prevent the use of banned substances in raising aquatic products.

Scientific agency tests showed water in shrimp ponds in the delta contained Cypermethrin and Deltamethrin which caused liver and pancreas failure. The substances could come from substances farmers use to kill other unwanted fish.

Shrimps also died when farmers failed to follow seasonal schedules and environmental protection regulations, including discharging waste water and mud from affected ponds into the environment, experts said. -- VNS
