Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to an ecological breeding method for breeding copper fish in an indoor cement pool. Background Art

[0002] Copper Fish ( Coreius heterodon ), belongs to the Cypriniformes, Cyprinidae, Gobioidea. There are three species of copper fish in China, namely northern copper fish, round-mouth copper fish and copper fish. Copper fish are mainly distributed in the Yellow River and Yangtze River systems in my country. They grow fast, have tender meat, high meat content, delicious meat, and rich nutrition. They are deeply loved by people and have high economic value and good breeding prospects. Copper fish is a Chinese endemic species, and there are few related research reports abroad. Domestic research on copper fish mainly focuses on basic biology such as classification, distribution, resources and their changes, early development, and genetic diversity characteristics, and they are relatively sporadic and lack systematic research. There is less research on the artificial domestication and reproduction of copper fish.

[0003] In recent years, affected by water conservancy project construction, environmental pollution and overfishing, the current situation of copper fish is worrying. The northern copper fish is on the verge of extinction, and the resources of round-mouthed copper fish and copper fish have sharply decreased. In the newly published "National Key Protected Wildlife List" in 2021, the northern copper fish is listed as a national first-class aquatic wild protected animal, the round-mouthed copper fish is listed as a national second-class aquatic wild protected animal, and the copper fish is included in the 2020 "National Key Protected Economic Aquatic Animal and Plant Resources List". How to explore and develop and utilize high-quality aquatic germplasm resources is one of the hot issues in the research of fishery development and water environment protection technology.

[0004] The existing technology lacks reasonable and standardized technology for artificially breeding copper fish. The survival rate of existing artificially bred copper fish to sexual maturity is low, which cannot cope with the situation of sharp decline and scarcity of existing copper fish resources, and it is difficult to meet market demand and people's demand for high-quality fish consumption. Summary of the invention

[0005] The present invention aims to at least improve one of the technical problems existing in the prior art. To this end, the present invention proposes an ecological breeding method for breeding copper fish in an indoor cement pool.

Based on the ecological breeding method, the artificial domestication of copper fish can be carried out in a standardized manner, and the copper fish can be bred to sexual maturity and then artificially propagated. On the one hand, a new excellent breeding variety can be developed for aquaculture to meet market demand and people's needs for high-quality fish consumption; on the other hand, it is conducive to reducing overfishing, restoring fishery resources, better maintaining the ten-year fishing ban in the Yangtze River and Poyang Lake, and generating huge social, economic and ecological benefits.

[0023] In a possible implementation of the first aspect, the aquaponics board is a hollow PVC board, so that after water is filled in, the aquaponics board floats on the water surface, and water lilies are planted in the aquaponics board to purify the water quality.

[0024] In a possible implementation manner of the first aspect, the first preset range specifically includes:

[0025] Micro-flow water flow rate is 50 L / h~150 L / h, and micro-flow water volume is 2 t / d~3t / d.

After draining the pool water for 24 hours, inject well water again. Maintain the water level at 45cm and turn on the aeration pump for oxygen aeration for standby use.

[0071] Micro-flow aquaculture:

[0072] The test water source used in this embodiment is groundwater, and the water temperature is 18-25°C all year round. Automatic water flow is set, and the cement pool maintains a water level depth of 40-70 cm, a micro-flow flow of 50-150 L / h, and a micro-flow volume of 2-3 t / d. The pH value, ammonia nitrogen and nitrite water quality of the cement pool aquaculture water body are tested once every Wednesday, and according to the changes in the water quality indicators of the cement pool aquaculture water body, the requirements of Ph: 7-8, ammonia nitrogen content in the water <0.2 mg / L, and nitrite <0.05 mg / L are met. The pool water is changed once every Sunday morning at 9:00, and the amount of water changed is 1 / 2 to 2 / 3 of the total amount of pool water.

Dissolve 1ppm trichloroisocyanuric acid in water and evenly sprinkle it on the cement pool to disinfect the cement pool. Drain the pool water after 48 hours. After draining the pool water for 24 hours, inject well water again. Keep the water level at 45cm and turn on the aeration pump for aeration and standby.

[0084] Micro-flow aquaculture:

[0085] The test water source used in this embodiment is groundwater, and the water temperature is 18-25°C all year round. Automatic water flow is set, and the cement pool maintains a water level depth of 40-70 cm, a micro-flow flow of 50-150 L / h, and a micro-flow volume of 2-3 t / d.

The pool water is changed once every Sunday morning at 9:00, and the amount of water changed is 1 / 2 to 2 / 3 of the total amount of pool water.

[0086] Release of reserve parents: 6 cement pools were prepared. On September 7, 2023, the team released 10 copper fish into each pool. After the water temperature of the transported copper fish reserve parents was slowed down, they were soaked in 5% salt water for 15 minutes.
