How to breed red eye trout artificially

Red eye trout is one of the high quality economic fish. Its meat is tender, delicious and nutritious. Red eye trout is a popular freshwater culture variety because of its fast growth, strong adaptability, miscellaneous food, low breeding cost and high price.

I. Pond conditions

The pond for breeding red eye trout requires sufficient water and good water quality. There is no pollution source nearby, the water retention performance is good, the water inlet and drainage are convenient, the bottom of the pool is flat and less silt, the area is about 1334~3335 square meters (2-5 mu), and the water depth is 1.2~2.0 meters. Pool water requirements "fat, live, tender, cool." The transparency of the pool water is maintained at about 25-40cm.

II. Pond disinfection influent

Excessive silt should be removed before the pond enters the water, and after the dry pond is exposed to sunlight in winter. 100 - 150kg quicklime slurry is used for disinfection per mu, 200- 300kg fermented and decomposed manure can be applied as base fertilizer per 667m2 after disinfection for 10 - 15 days, and then the water is filtered by 60 mesh silk screen.

III. Fish stocking

Select healthy and lively high-quality red eye trout fry, fry into the culture pond before the available 3%~5% salt water immersion for 5~10 minutes. The pond for main fish cultivation is used for stocking 800-1200 winter fish per mu and 100- 200 fish per mu in the mixed culture pond.

IV. Feeding management

1. Feed feeding. Algae, organic detritus and grass can be used as feed for red eye trout. Red eye trout like to eat artificial compound feed, the main pond, with complete compound feed feeding, red eye trout feed crude protein content is about 30%, but also can be used as fine green algae, water grass, ryegrass, vegetable leaves as auxiliary feed red eye trout. The daily feeding amount is 3%-8% of fish weight. Usually cast once in the morning and afternoon. Also according to weather, water temperature, water quality and feeding conditions of red eye trout, determine the reasonable feeding amount of feed. Feeds are more vigorous in June ~ July and September ~ October, and a little slower in midsummer.

2. Water quality control. Every day noon open 1-2 hours aerator, open aerator at night according to weather conditions, in case of red eye trout floating head. The pH of the pond water is maintained between 7 and 8.5. In the middle and late stages of breeding (especially in the high temperature season), new water should be replaced in time to keep the water fresh. Transparency is controlled at 25-40cm. Every 10-15 days, 10-15 kg of quicklime water per mu is sprinkled once in the whole pool to make the pool water slightly alkaline, so as to facilitate the growth of red eye trout and the prevention and control of fish diseases. Fish farmers with better conditions can apply EM solution, probiotics and other microbial preparations every 12-15 days according to the water quality and temperature of the culture pool to improve the water quality.

3. Daily management. In the breeding process, insist on frequent observation and frequent pond patrol. Observe water quality changes, fish activities, feeding, whether there is disease, etc., and find problems and deal with them in time. The garbage around the fishing pond, the residual bait on the feeding platform (field), the floating matter on the pond surface, etc. should be cleaned frequently.

V. Fish disease control

The red eye trout has strong adaptability, low infection rate and mortality rate. However, the prevention and control should still adhere to the principle of "prevention without disease, early treatment with disease, comprehensive prevention and active treatment". In addition to disinfection of fish species before entering the pond, fresh grass (bait), food field and tools should be disinfected. Fish medicine should be regularly used for prevention of red eye trout disease in summer and autumn.
