Loc Huu Tran is Founder-Director of ShrimpVet Laboratory, Vietnam as well as Assistant Professor at the Faculty of Fisheries, Nong Lam University in Ho Chi Minh. At ShrimpVet, he leads a young team of over 80 people working on various fields related to aquaculture including: diagnostics, aquaculture products testing, disease prevention technologies, hatchery technologies, and farming technologies. ShrimpVet, a private independent research lab, is now recognized as an international research centre serving the industry in Vietnam and in several other aquaculture countries. In 2013, Loc obtained his PhD in Environmental Sciences and Microbiology (Shrimp Pathology) from the University of Arizona, USA. His dissertation was on the determination, characterization, and control measures of the agent of the early mortality syndrome (EMS) or the acute hepatopancreatic necrosis syndrome (AHPNS) in farmed penaeid shrimp. Loc has authored and co-authored several papers on EMS and AHPND as well as on disease management for the pangasius.

Session 5 Managing Productivity – Survival Rates & Disease Control
Presentation Science In Shrimp Farming And Recent Innovations In Production In Vietnam


The very fast-growing shrimp farming industry in Vietnam in recent years has improved livelihoods of hundreds of thousands farmers in Vietnam. The quick transition from low stocking density black tiger shrimp Penaeus monodon culture to the intensive farming of the Pacific white shrimp Penaeus vannamei has encountered various obstacles of disease outbreaks, environmental pollution and gradual decease of survival rates. Early mortality syndrome/acute hepatopancreatic necrosis disease (EMS/AHPND), white faeces disease (WFD), Enterocytozoon hepatopenaei  (EHP) and muscle necrosis are among the most important emerging diseases.

In practice, Vietnam has been moving a long way from traditional farming systems with less biosecurity and chemical-based farming protocols to more controlled farming methods since the outbreak of EMS/AHPND in 2010 and EHP in 2014. Several new practices have been applied including screening for diseases (EMS/AHPND, EHP, WSSV) for post larvae and grow-out shrimp during farming cycle, better pond preparation with good probiotics bloom before stocking, plastic-lined pond farming protocol, nursery phase at the farm level, routine/daily application of bioremediation, daily shrimp pond waste removal, probiotics top-coating in feed, and functional feed. With better adaptation to new technologies, it appears that our shrimp farming industry is becoming more predictable. This explains the fast increase in Vietnam’s shrimp production in recent years.

There have been so many advances in feed technology including ingredient pre-fermentation, novel ingredients that can partially replace fishmeal and fish oil, carotenoids and micronutrients for improving shrimp quality, enzymes technology, prophylaxes and immunostimulants for disease management. Shrimp feed with no or very little fishmeal and fish oil is now viable. The shifting from fishmeal and fish oil-based shrimp feed to more environmental friendly feeds could be an assurance for the fast development of shrimp farming in Vietnam in the coming years. Today, feed technology has become an essential part of adaptation to intensive farming, health management and improving productivity.
