With the project "Manufacturing industrial food from raw materials to feed sweet snails in Vietnam", a group of researchers from the Research Institute for Aquaculture III has created a suitable formulation and manufacturing procedure for the feed for sweet snails. As far as known, no other country in the world has produced feed for sweet snails in order to industrialize snail farming till now.
Use locally sourced ingredients
Dishes made from sweet snails are Vietnamese specialties. The potential of sweet snail farming is extremely huge in Vietnam due to high demand in both domestic and foreign markets, and current supply has yet to meed demand. This is one of the most important seafood exporting items that create jobs and increase income in the coastal area. So far, sweet snail farming has been expanded to many provinces such as Quang Ninh, Hai Phong, Thanh Hoa, Khanh Hoa, Binh Thuan, Kien Giang,...
In some Central Vietnam provinces, sweet snails farming are strongly developed, accounting for a large proportion of aquaculture
However, the current level of snail farming in our country is still unprogressive with extensive traditional farming, using fresh food such as shrimps, fish, mollusks to feed the snails. This leads to environmental pollution, difficulty in controlling disease, and low productivity and efficiency. In fact, nowadays in Vietnam, research on feeding production for sweet snails are still primitive and experimental. There is no industrial feeding product for commercial snail farming, not only in Vietnam but also in the world.
From this observation, the Research Institute for Aquaculture III implemented the project "Manufacturing industrial food from raw materials to feed sweet snails in Vietnam", led by MSc. Tran Thi Thu Hien. This project aims to build the technological procedure and equipment to produce snail feed from enzymes and other readily available ingredients, thus improve the economic efficiency of sweet snail farming and reduce environmental pollution.
This is part of the Program on developing and applying biotechnology in the field of processing industry till 2020 overseen by the Ministry of Industry and Trade. On October 13th, the Ministry of Industry and Trade organized the final result approval of the scientific and technological task above.

Success achieved thanks to the application of enzyme technology
Nowadays, the application of biotechnology in improving product quality, product efficiency, and environmental quality of the aquaculture industry plays a crucial role in sustainable development. Enzyme technology is considered one of the optimal options to help solve and enhance feeding efficiency and minimize environmental pollution resulted from aquaculture activities.
MSc. Tran Thi Thu Hien - Research manager of the project, said that the research team has produced synthetic feed for sweet snails based on a mixture of ingredients such as fishmeal, shrimp meal, and several materials derived from plants such as cornstarch, rice bran flour,... This process contributes to the reduction in costs, and farmers won’t have to depend on natural food sources anymore, thereby obtain high economic efficiency.

In particular, the research team has applied enzyme technology to help improve digestability, maximize nutrition absorbed to promote a healthy digestive system. The synthetic feed products produced under this project were test used at Khanh Hoa Fisheries Science and Technology Joint Stock Company.

According to Mr. Nguyen Hung Dien - Chairman of Khanh Hoa Fisheries Science and Technology Joint Stock Company, previously, fresh fish was used to feed sweet snails. As the snails’ eating behavior is to suck only the flesh of fresh fish, the bones and skin of the fish would sink to the bottom of the pool, causing , disease spreading, and farming productivity limitation.
"Sweet snail is an animal that eats fresh food using suction so it is necessary to produce suitable food for the snails’ eating behavior", Mr. Nguyen Hung Dien emphasized.
The research results are synthetic feeding products for sweet snails which meet nutrient requirements such as protein, lipid, fiber,... Snails raised by these products achieve equal size and are of healthy state. It is extremely impressive that these products are produced from agricultural by-products, which are always available in Vietnam.

“It will be great if all other snail farms can also apply the results of the project "Manufacturing industrial food from available raw materials to feed sweet snails in Vietnam”. We highly appreciate that this project can combine both scientists’ research and manufacturing enterprises," Ph.D. Nguyen Manh Dung – Deputy Secretary-General of Vietnam Food Science and Technology Association stated.
