Dong Nai still has a lot of room to break through to become a high-tech seafood production area.

With advantages in water surface area, large agricultural land fund and sustainable development orientation, Dong Nai province has a lot of room to break through and become a high-tech aquaculture production area in the South.

Thanks to bold application of science and technology in production, many aquaculture households in Dong Nai have improved productivity, reduced costs and increased profits.

With advantages in water surface area, large agricultural land fund and sustainable development orientation, Dong Nai province has a lot of room to break through and become a high-tech aquaculture production area in the Southern region.

High technology applications

To meet market demand, many aquaculture households in Dong Nai have boldly invested in high-tech aquaculture systems to help manage the environment and livestock, increase the number of crops per year, and bring outstanding economic efficiency to farmers.

Thanh Cong Agricultural and Aquatic Services Cooperative (Phuoc An commune, Dong Nai province) has been implementing high-tech shrimp farming for many years. This model is applied quite synchronously from selecting quality breeds to investing in a tarpaulin-lined pond system, with a water treatment system, waste treatment in the pond, ensuring a good environment for shrimp growth, and good disease control.

Mr. Nguyen Huy Binh, Director of Thanh Cong Agricultural and Aquatic Service Cooperative, said that applying high technology to brackish water shrimp farming brings economic efficiency thanks to the shrimp yield being many times higher than the traditional farming model.

When applying high technology to production, the pond system is invested more systematically, helping to increase the number of crops per year, increasing the yield of each crop. In particular, diseases are well controlled so farmers do not worry about crop failure.

“Thanks to the high economic efficiency of the farming model, the cooperative members have now expanded the high-tech shrimp farming area to more than 30 hectares. This model has also been encouraged by the local government to be replicated, with many support policies; in which, the most favorable is the local government's interest in investing in roads and electricity systems to serve production,” said Mr. Binh.

Not only shrimp farming is applied high technology in production, many aquaculture households and fish farms on rivers are also gradually applying science and technology to increase output, reduce costs and improve production efficiency.

Mr. Nguyen Ngoc Thanh's family, owner of Phu Dien Fish Aquaculture Farm (Phu Hoa commune, Dong Nai province) has a 40-hectare fish farm and a system of 166 fish rafts on La Nga river.

In addition to common freshwater fish, he also raises specialty fish such as catfish, catfish, and goby fish, which bring high economic efficiency. On average, each year his facility supplies about 2,000 tons of freshwater fish to the market for major wholesale markets in many provinces and cities across the country.

Mr. Thanh said that he inherited the secrets of raising fish in rafts from previous generations in his family. Every day, he researches, improves, and applies new science and technology to production.

He designed a chain of sturdy fish rafts with wide railings for workers to move around easily. The rafts are covered with shade nets. When feeding the fish, the food must be spread slowly, divided into several batches during the day, and the amount of food must be adjusted according to the weather each day. The shade nets help the fish avoid heat and sunlight shock when they come up to the surface to eat.

Thanks to that, during the rainy season, many fish farming areas on La Nga River cannot release fish, but Mr. Thanh's fish farms still maintain a stable fish supply year-round, without cutting off the market supply, earning billions of dong in profit each year.

Mr. Nguyen Van Vien, Chairman of the People's Committee of Phu Hoa commune, said that the whole commune has nearly 10km of La Nga river flowing through it, and about 200 hectares of ponds and lakes raising freshwater fish.

Currently, freshwater aquaculture in the locality brings high economic efficiency with stable output. This is an advantage for the locality to continue to develop in the future.

The commune's orientation is to develop safe freshwater aquaculture, high-tech aquaculture associated with tourism development; in which, it pays attention to and supports fish farmers to continue expanding the consumption market and diversifying aquatic products.

In particular, La Nga River has many delicious fish specialties, especially catfish. Therefore, the locality wishes to build a brand for this fish that brings high economic value.

Lots of room for development

According to the Department of Agriculture and Environment of Dong Nai province, the locality has a lot of room to develop the aquaculture industry, with nearly 10,000 hectares of ponds, more than 1,500 rafts and more than 6,000 fish cages on the river.

In addition, the whole province has 20 aquaculture reservoirs with an area of ​​nearly 52,000 hectares. The total aquatic product output in the area is estimated at more than 82,000 tons, of which the output of farmed fish accounts for about 89%, shrimp accounts for 8%...

Currently, the province has 27 domestic-invested enterprises and 18 foreign-invested enterprises operating in the aquaculture sector. In addition, Dong Nai province has established 8 aquaculture cooperatives, forming linkage chains; in which, there are many aquaculture cooperatives applying high technology.

Mr. Nguyen Truong Giang, Head of the Department of Animal Husbandry and Fisheries of Dong Nai province, said that although Dong Nai is a coastal province, the river and lake system in the area is quite rich, with notable examples being Tri An Lake, Dong Nai River and La Nga River.

In particular, after the administrative merger, the water surface area and rivers of the province were expanded, creating more favorable conditions for people to develop aquaculture; at the same time, the consumption market was also diversified and the room for development was increasingly large.

According to Mr. Nguyen Truong Giang, in the coming time, Dong Nai's seafood industry will develop in a sustainable direction, based on the production value chain and market demand.

The province will focus on raising specialty aquatic species, promoting intensive farming models applying high technology. Currently, some high-tech aquaculture models in Long Thanh and Nhon Trach have brought positive results, and in the coming time will be replicated throughout the province./.
