The fish has the advantages of fast growth, large size, high yield, wide eating habits, easy feeding, white and tender meat, delicious taste, rich nutrition, no muscle thorn, easy processing and so on. The fry can grow to 500-800g in one year, 1500-2000g in the second year, and the maximum individual can reach 15kg.
Basha fish is an important freshwater aquaculture species in Southeast Asian countries. It belongs to Silurus, and Paugusiushamiltoa, which belongs to Silurus, is a scaleless fish. It is a high-quality economic fish unique to the Mekong River Basin. In Vietnam, it is transliterated as "CABaSa", which means "three-fat fish", because this kind of fish accumulates three kinds of fat in its abdominal cavity during its growth, accounting for about 58% of its weight.
The suitable water temperature for the growth of Basha fish is 20℃~32℃, and the optimum water temperature is 24℃~30℃. When the water temperature drops to 16℃, stop eating. When the water temperature is lower than 10℃, it will cause frostbite and even death. Overwintering and heat preservation should be done well in parent culture of Basha fish. From late June to early April of the following year, the water temperature was kept above 20℃, and the feed was 1%~ 1.5% of the fish weight. From early April to mid-May, the cultivation was strengthened, and the feed was 2% ~ 2.5% of the fish weight. Tilapia or pond fish puffed material with protein content of 28%~32% can be used instead of feed.
The water temperature of the incubation pool is basically the same as that of the parent pool to avoid excessive temperature difference; The bottom of the microporous aeration tube pool is aerated and oxygenated, and a slight water wave is formed on the water surface; When the water temperature is 28℃, the fertilized egg can hatch out of the membrane after 20 hours, and the hatching rate is 80% ~ 90%. The seedlings that just came out of the film crawled on the bottom of the pool, with no pigment on the body surface, and turned light gray after one day, concentrated in the corners around the bottom of the pool.
