Dialogue on low-emission and sustainable shrimp industry within circular economy
During VietShrimp 2024, on the afternoon of March 20th at the Cà Mau Convention Center, the second seminar session was held with the theme: Dialogue on low-emission and sustainable shrimp industry within circular economy, chaired by Trần Đình Luân, Director of the Department of Fisheries.
Nearly 10 presentations were delivered during the seminar, focusing on finding solutions for a low-emission, sustainable shrimp industry within the circular economy framework. Aquaculture is an important economic sector, contributing to food supply and exports assurance. However, aquaculture, especially shrimp farming, is significantly affected by climate change and greenhouse gas emissions.
Currently, the Vietnamese shrimp industry faces numerous challenges such as higher production costs compared to Ecuador and India, low success rates, poor quality shrimp seeds, pollution in the Mekong Delta, widespread diseases, etc. To reduce shrimp production costs, Dr. Nguyễn Duy Hòa, Global Technical Director of Empyreal & MOTIV Department at Cargill, emphasized the need to focus on solutions regarding shrimp broodstock, pollution control, reduction of feed, materials, and drugs costs, disease management, and increase in survival rates and success rates.
Regarding disease control in shrimp, Dr. Nguyễn Tấn Sỹ, Deputy Head of the Institute of Aquaculture, Nha Trang University, introduced a method of controlling bacterial diseases in shrimp without using antibiotics. Bacterial diseases, though not as dangerous as viral diseases, cause significant economic losses to the shrimp industry annually. Dangerous bacterial diseases include EMS (AHPND), TPD (Translucent Post-Larva Disease). Recently, scientists at the Institute conducted experiments supplementing Microbial protein into feed. The results showed that shrimp immunity was enhanced, manifested through increased total hemocyte count, increased PO and Lyzozyme levels.
An expert from the National University of Hanoi stated: “The current announcement of aquatic diseases is weak, and there is a lack of support policies for disease researchers. Therefore, the government needs mechanisms to support researchers studying new diseases. If the SPF shrimp seed is not available, productivity cannot be achieved as expected.”
Based on the discussions of the speakers, Trần Đình Luân emphasized that to enhance value in the aquaculture industry, farmers need to be wise and limit the use of antibiotics. To apply scientific and technological advances into the shrimp industry, careful guidance and thorough discussions are necessary.
