A group of talented individuals from RMIT University are developing a vaccine against Edwardsiella ictaluri bacteria. This will aid the farming of tra basa catfish in Vietnam.
Professor Peter Coloe said, aquaculture is a critical element of the Vietnam Globalisation program. He is the Head of Applied Science at RMIT University. He then added, the welfare of tens of thousands of households, is influenced by successful productivity at the farm level. Coloe says RMIT would like to help young scientists from Vietnam solve the fish farming problem.
Catfish fingerlings would be immersed in a solution containing the vaccine, then released into the ponds. This would then protect the fish until harvest.
The strategy is to protect the fish and induce immunity. A live vaccine is the best because it stimulates all types of immunity. The fish will be provided with a longer life span.
Professor Coloe and Ms. Phan Ngoc Thuy, are presently working with fish samples from Vinh Long and Can Tho. So far they have found that the over stocking of the ponds has contributed to the spread of bacteria.
In an experiment, they had 90 then 30 fish per cubic metre in separate ponds, and measured their feeding habits.
In the pond with 90 fish per metre water quality was lower, with a stronger likelihood of bacteria being present. Ms. Phan said, there is likely to be a decrease in nutrient conversion efficacies.
