SURVEYING THE CURRENT SITUATION OF USING PROBIOTICS, CONTROLLING DISEASES AT SHRIMP FARMINGS IN THE CA MAU PENINSULA OF VIET NAM

Abstract

In order to provide the basis for the application of scientific and technological advances, reorganizing shrimp
farming in sustainable and bringing high economic value to the Mekong Delta. The study surveyed the current situation of breeds, farming methods, environmental monitoring control, Vibrio sp. and the use  of probiotics of shrimp farmers in the Ca Mau peninsula by interviewing 200 shrimp farmers and 20 specialized fisheries officers in Ca Mau, Soc Trang, Bac Lieu and Kien Giang provinces. The results showed that the shrimp breeds selected for farming originated from the Central and Southwest provinces. There are four popular farming methods: intensive, semi-intensive, improved extensive, and rice-shrimp. The intensive farming had the highest rates of the initial quarantine of shrimp postlarvae (74%) and Vibrio test (57%). All shrimp farmers working
on the intensive and semi-intensive farmings used probiotics. The rates of probiotic use in the improved extensive and riceshrimp farmings were lower, only 60% and 40% respectively. The results suggested that shrimp farmers working on the semi-intensive and intensive farmings paid more attention to the use of probiotics as well as the test to prevent the disease in shrimp.
