Fish Kill Alert

High density of farmers, plus low water levels, weak currents lead to lack of oxygen leading to massive fish deaths on Cai Vung river, Dong Thap province.

Dong Thap Department of Animal Husbandry, Veterinary and Fisheries has just analyzed results of causes of dead fish in Cai Vung river.

According to the analysis results, fish died due to local hypoxia. Dissolved oxygen content in water (referred to as DO) where dead fish occurs is only 1.0 – 2 mg / l, while the required oxygen requirement according to DO> = 4 mg / l.
