Phu Tho has successfully researched and produced rare and precious fish

The topic "Application of artificial reproduction technology and testing of commercial fish farming in Phu Tho province" conducted by Phu Tho Fisheries Department has been bringing about high efficiency in propagation and develop this kind of fish for farmers to raise commercial products.

The initial success of the project has contributed to the regeneration of precious genetic resources, as well as the protection of natural resources that are in danger of depletion.

The project has successfully received 3 technological processes, including the breeding program of broodstock, the process of artificial reproduction of fish and the process of raising fish suddenly . Based on that, Phu Tho Department of Fisheries organized the study of this species in two types of models: Fish farming in earthen ponds using green food combined with industrial feed, as control Fully using green food and cage farming model using green food combined with industrial food, control is to use green food completely.

After 20 months of raising, raising fish suddenly becomes strong and fast, average weight is nearly 2kg / head.

Through acceptance and evaluation, fish farming suddenly in earthen ponds using green food combined with industrial feed, control is to use green food completely; Fish cage culture model using green feed combined with industrial feed, control is to use green food completely. The results are 100-142% compared to the target.

After 2 years of implementing the model of goby seed production: The rate of maturation is over 50%, the laying rate is more than 73%, the fertilization rate is over 55%, the hatching rate is 62%, the rate of fertilizing from the to reach 51% .

According to the actual assessment, the model of commercial fish farming in earthen ponds using green feed combined with industrial feed gains profit of more than 126 million VND / ha. The model of commercial fish farming in cages using industrial feed combined with green food earned a profit of 172 million VND / cage of 100m ³ in the same 20-month culture period.

Mr. Thieu Minh The, Xuan Loc commune, Thanh Thuy district, said that the Phu Tho Department of Fisheries supported 100% of the seedlings (800 heads / cage) and 50% of the cost of making cages. Raising pilot cage 1 cage. After 20 months of raising, raising fish suddenly becomes strong and fast, average weight is nearly 2kg / head.

If selling at the current market price from 250,000 to 300,000 / kg, it will also earn hundreds of millions of interest, 5 to 6 times higher than other fish varieties.

Raising fish suddenly in commercial cages is more economical than farming in earthen ponds, 1 cage with volume of 100m ³ gets higher profit when raising in an earthen pond with an area of ​​1ha.

The project has also trained 7 technicians who are proficient in the model and it is important to complete the seed production processes suitable to the province. Thereby contributing to restoring fisheries resources by stocking fish suddenly back to the natural environment on the Lo River from artificial fish sources, and the potential of raising freshwater fish on the river to replicate the model effectively. bring high profits to the people.
