The farm will have square ponds for running trials. Water filtration and treatment is an important feature of this farm. “I want to show solutions along the value chain. I want to show that we start with good algae for better larval culture through to technology without the use of antibiotics. I want to contradict some practices such as at less than 30 days, the pond system is very immature and is building up Vibrios populations. I relate this to why having tilapia in ponds works to prevent disease. Vibrios in clean water will collapse if starved of organic matter. This is the concept of pond conditioning. Having a nursery phase with stronger shrimp is a way forward. I believe EMS and WFD can affect 1-2g shrimp too. Perhaps feeding with nutrient dense diets (albeit expensive) diets will strengthen shrimp during this phase. "When post larvae performance is good, we then combine this with good farming protocols and new innovations in feeds. With the latter, I mean working with genetics to find the feed additives which will bring out the best of a particular stock.” Loc is keen

to start some training programmes. “I expect these programmes to be popular with the feed industry. Perhaps they can give vouchers to their clients to attend these courses. “In the end, I do not want aquaculture to be so unpredictable, I want to bring it closer to a science,” said Loc. During his pitch at the recent Aquaculture Innovation Competition Vietnam, Loc explained his future plans for ShrimpVet. “We want to expand in several directions which will require funding support. The market potential for services in disease management is there. Our goal is to expand our research capacity three-fold with more on-site services. The plan is to have 8-10 field centres. We need to expand the team to provide services such as shortening the time to diagnose diseases to assist innovation. We need to shorten the time from innovation to field application and farmer acceptance of successful ideas and provide independent training of farmers on the science of aquaculture.”
In charge of the histology laboratory, Vy Van uses histology as a general diagnostic method to detect presence of pathogens or abnormal changes in the cell structure screen. Histopathology method is used for diagnosis and screening viral diseases in shrimp (WSSV, MBV, HPV, IMNV, etc.), lesions of EMS /AHPND, microsporidian (EHP).
