Quang Binh: Successful farming of lentils in land ponds

Lentils are considered to be high economic fish species and the leading freshwater specialty in the North. This rare and precious fish, which lives only in the Red River system, has been successfully experimented in Quang Binh.

Lentil is successfully cultured in earthen ponds, not only opens a new direction for enriching aquaculture households in Quang Binh but also contributes to the conservation of rare and precious wild fish, which are gradually exhausted, need to be protect.

Lentil fish dots are rich in nutrients, delicious meat, favored by the market so the price is very high. In 5/2011, Quang Binh Agricultural and Fishery Extension Center implemented a farming model to test commercial spotted fish in pond.

The farm of Mr. Bui Viet Phuong in Viet Trung farm town, Bo Trach district, Quang Binh province is the unit chosen to implement this new farming model with the scale of 2,200m ² . After importing the seed at the Northern National Aquatic and Freshwater Center under the Aquaculture Research Institute I in Hai Duong province, the lenticular fish is stocked with 1,100 animals.

Grazing fish farming

Breeding fish is stocked with density of 0.5con / m ² . Before and during the raising process, officials of the Quang Binh Center for Agricultural and Fishery Extension organized training and guidance on farming techniques and together with the owner of the farm to closely monitor the growth and development of lentils. dot.

After 17 months of farming, the fish grows and grows well, the survival rate is about 80%, in which over 60% of the fish reaches the weight of about 1.3-2kg / head. The output of spotted fish in the pond when the harvest is estimated to reach over 900kg with an average selling price of 200,000 VND / kg, the total revenue is estimated at nearly 200 million, except the cost of farmers also earns nearly 50 million VND, much higher. Traditional farming objects.

Mr. Bui Viet Phuong happily shared that this fish lives mainly in the Red River system, thinking that this fish will be difficult to raise but in fact they are well adapted to the local natural conditions, especially Very good container with cold environment, less disease, no care."At the peak, we sell for 300,000 to 350,000 VND / kg. After selling this fish, we will definitely continue to invest , " said Phuong.

According to the assessment of the Center for Agricultural and Fishery Extension in Quang Binh province, the fish spotted in the pond are well adapted to the new culture conditions, less epidemics and high survival rate. Compared with the technical process of fish-spotted breeding of the Research Institute for Aquaculture No. 1 (after two-year farming period, the average weight is 1-1.5kg / head, the productivity reaches 4-5 tons / ha, the speed is The growth and development of the spotted fish of the pilot farming model on the farm Bui Viet Phuong is very good.

Also according to the Center for Agricultural and Fishery Extension in Quang Binh province, because the source of fingerling must be purchased at the National Center for Freshwater Aquaculture in the North of Hai Duong Province, so the transportation cost is high and not active. The long culture period (from two years or more), high investment costs, can only be implemented on potential farms and seafood companies.

Although the new object, the market is not used yet, the spotted fish have high nutritional value and bring many benefits to farmers, providing high quality products to consumers. Therefore, the Center will continue to implement the model in order to have conditions for selection of gilts for seed production research; proceeding to improve the process of raising lentils in land ponds.

At the same time, the Center organizes training and technical guidance for households who want to learn how to grow commercial grappling ponds in earthen ponds. In the future, the Center will implement other types of farming such as cage culture, raising on sand ponds to take advantage of the available potential of the locality.

The successful trial farming of commercial spotted fish in the pond has not only brought about high economic efficiency, contributed to diversified farming forms, opened a new direction for freshwater fish farming in Quang Binh but also contributed Preserving wild rare and precious fish breeds.
