According to the calculation of Mr. Tran Quoc Duc - owner of the yellowfin white pomfret farming model in Vinh Thinh village, Thach Lac commune (Thach Ha, Ha Tinh), after 6 months of farming, the family will sell about 12 tons of fish, earning a profit of 350 - 400 million VND/ha.
The model of raising yellowfin pompano in a tarpaulin-lined pond of Mr. Tran Quoc Duc (in black shirt) was deployed from the beginning of 2023.
Mr. Tran Quoc Duc’s model of raising yellowfin pompano in a tarpaulin-lined pond is a new model in Thach Lac commune. Although it has only been raised since the beginning of this year and is about to harvest the first batch, the model has initially brought positive signals such as: good fish growth, high survival rate, stable consumption and price.
Sharing about the process of getting acquainted with this fish species, Mr. Tran Quoc Duc said: “Previously, my family specialized in raising white-leg shrimp, but the income was unstable, so we decided to change our livestock. In early 2023, after a tour to learn about the experience of raising yellow-finned white pomfret in Nha Trang city (Khanh Hoa), I invested nearly 1 billion VND to rent machinery to renovate the pond, line the pond with tarpaulin and import more than 30,000 fingerlings to release in 6 ponds with an area of 1.5 hectares.
"After 5 months of farming, up to now, the survival rate of the fish has reached over 85%, the weight is 0.4 kg/fish. It is expected that in more than 1 month, the fish will reach an average weight of 0.6 - 0.8 kg/fish; the estimated output is 12 tons, with a selling price of 140 - 150,000/kg, it will bring a profit of 350 - 400 million VND/ha" - Mr. Duc shared.
With 6 ponds, Mr. Duc uses 1 pond of over 2,500 m2 as a nursery area for fish under 1 month old since the import. The remaining 5 ponds with a total area of over 12,500 m2 are stocked with fish 1 month old or older and raised for another 5 months until sold.
Yellowfin pompano grows well after 5 months of raising.
Before stocking, Mr. Duc carefully renovated the pond, sprinkled lime, and treated pathogens and harmful microorganisms. To keep the pond clean and airy, and improve the water quality, he used probiotics to improve the water environment, limiting the growth of harmful fungi, bacteria, and algae.
Sharing about the farming process, Mr. Duc said: "White-finned pompano raised in tarpaulin-lined ponds must pay attention to ensuring the amount of oxygen; the suitable temperature for fish to grow and develop well is from 26 - 32 degrees Celsius. Fish food is industrial food in the form of floating pellets, algae, plankton, large fish can also eat chopped fresh fish and depending on the size of the fish, adjust accordingly."
Choosing the right feeding time is very important to ensure good fish growth.
In addition, he will feed the fish twice a day, in the morning and afternoon. On cold days (water temperature below 17 degrees Celsius) or hot days (water temperature above 36 degrees Celsius), he should not feed the fish.
After 5 months of farming, Mr. Duc assessed that yellowfin pomfret is an effective and stable income farming species. Although the profit is not as high as that of whiteleg shrimp farming, farming this type of fish is stable, has less risk, and is also very popular in the market. After selling this crop, his family will continue to raise it.
Ensuring the farming environment will help fish achieve high survival rate and rapid growth.
Mr. Nguyen Xuan Tung - Vice Chairman of Thach Lac Commune People's Committee said: "Mr. Tran Quoc Duc's model of raising yellowfin white pomfret is an effective way to change the livestock structure in the commune. The locality is mobilizing people to visit, learn and gradually convert shrimp farming areas that are often damaged to raising other economic fish species or intercropping a shrimp crop with a fish crop in a year for better profits."
