The bronze featherback fish model currency interest rate over 110 million VND/0,7ha

Evaluating the intensive bronze featherback fish farming model after 9 months deployed, initial results show positive results.

Cu Chi is a suburban district of Ho Chi Minh city (TP.HCM) that has an East canal water system flows all year, farming fish effectively, include to bronze featherback fish. This is one of kind of freshwater fish that has a high economic value, high meat quality, popular with the customer; At the same time, with simple technical nourish, less disease… is an advantage for farmer invest this model.

The weight of fish via 9 months of farming reach 500-600 grams/fish, with medium length from 34-36 cm/fish. The total production of the model reaches 8.700 kg fish, with medium price from 72.000-75.000 VND/kg, after deducting expenses, the model of average interest income reached more than 110 million VND/ 0.7 ha/4 households.

Therefore, the households suggest that when transporting fish breed, the fish should be put in the bag, the farmer will soak the bag with water in 10-15 minutes and then drop the fish, it helps fish less thermal shock, reduces undergo some loss rate, help farming process more propitiously, more high effection.

Besides that, in the farming process, the household always keeps a close eye on the model, in addition to the basic techniques supported and advised by extension technicians, each household also has farming methods suitable to the effective model reach increasingly high. For example, the household of Mr. Hau said that at the begin of drop breed, the fish still small, but the pellets supported by extension workers are in large in size, the fish cannot eat too much, so he ground the bran very small to make the fish more efficient. About the household of Mr. Lan has another way is to bring bran to soak out and drop for fish eat…
