Embodiment 1

[0042] Collect the fertilized eggs of pike perch, place the fish nest with the fertilized eggs in the hatching tank at a water depth of about 0.3 meters, control the water temperature at 10-18°C, and about 15 hours after about 50% of the fertilized eggs lay eggs (approximately Laboratory conditions in similar environments shall prevail), and 35ppm of Rhodopseudomonas sphaericus ( Rhodopseudomonas sphaeroides ), 15ppm Rhodopseudomonas palustris (R. palustris ); on the 5th to 30th day thereafter, 12ppm Rhodopseudomonas sphaericus, 8ppm Rhodopseudomonas palustris, and about 20 / ml Brachionus citriformis were put in every day;

[0043] From the 31st day to the 40th day, a sufficient amount of rotifers and Artemia larvae were put in every day, and the pH of the water body was kept at 7.5-8.0 throughout the cultivation process, with a daily water change rate of 2-3%, circulating micro-flow water, sufficient oxygen, and pure water. Oxygenation, water oxygen content> 7.6mg / L, 30% wat...

Embodiment 2

[0050] Collect the fertilized eggs of pike perch, place the fish nest with fertilized eggs in the hatching tank at a water depth of about 0.3 meters, control the water temperature at 10-18°C, and wait for about 10 hours after about 50% of the fertilized eggs spawn (approximately Laboratory conditions in similar environments shall prevail), and 40ppm of Rhodopseudomonas sphaericus ( Rhodopseudomonas sphaeroides ), 10ppm Rhodopseudomonas palustris (R. palustris ); from the 5th to the 30th day thereafter, put 10ppm Rhodopseudomonas sphaericus, 7ppm Rhodopseudomonas palustris, and about 10 / ml Brachionus citriform rotifers per day;

[0051] From the 31st day to the 40th day, put enough rotifers and Artemia larvae every day, keep the pH of the water body at 7.5-8.0 during the whole cultivation process, change the water rate 2-3% every day, micro-flow water, sufficient oxygen, fry density 300-500 tails / m 2 ;

[0052] On the 41st day, when the fry grow to 3-5 cm, move the fry to t...

Abstract

The invention provides a cultivation method for purifying water and increasing the growth rate of fish fries, fish fingerling and adult fishes, and a six-level water processing method. By utilizing the appropriate ecological microorganism, the functions of regulating the water quality, purifying the water source and providing fish bait are played in the important period of different stages for the fish incubation, the fish fry growth, the fish fingerling cultivation and the adult fish growth. The fish growth rate is increased, the probability of the fish disease occurring is reduced, and therefore the production efficiency for the fish cultivation is improved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an aquaculture method for fry, fingerlings and adult fish. Background technique [0002] The breeding process of fry and adult fish is inseparable from the water body environment. Due to the development needs of intensive aquaculture, the self-pollution of aquaculture water is very serious. Water is the material basis of aquaculture, and the role of water environment in aquaculture water is getting more and more attention. In recent years, in order to improve the aquaculture water environment, fish farming in circulating water is used to avoid external pollution and reduce the cost of aquaculture. be spread. The microbial ecological breeding mode is also a biological control technology to prevent the pollution of aquaculture water bodies. It can control the reproduction of algae in eutrophic water bodies to a certain extent and reduce the turbidity of water bodies. Howe...
