Problems solved by technology

There are many disadvantages in this farming model: 1. The water quality cannot be guaranteed, and there is no countermeasure if pollutants flow into the sea area; 2. Due to the limitation of the water temperature in the sea area, the water temperature in spring and winter is low, which affects its growth, and the water temperature in summer is high, so fish must be produced; 3. Affected by corresponding pathogenic microorganisms and parasites, it cannot be controlled; 4. The amount of feeding is difficult to control, and the corresponding bait coefficient will be very high. The bait coefficient of the compound feed is as high as 2 or more, which not only causes waste, but also pollutes the sea area; 5. Time to market and fish size are greatly affected by seasons

Embodiment Construction

[0026] Below in conjunction with embodiment describe in detail:

[0027] A closed circulation aquaculture method for Otaki hexalis, including selection of aquaculture water source, establishment of aquaculture environment, control of aquaculture density and aquaculture water temperature, regulation of aquaculture water quality, regulation of aquaculture water dissolved oxygen, and selection of aquaculture bait and feeding, the management of breeding sub-ponds, and the prevention and treatment of breeding diseases, the specific conditions are as follows:

[0028] (1) The selection of the aquaculture water source is to use well seawater, the suspended particles in the well seawater are less than 3mg / L, the pH value is 6.7-8, and the salinity is above 25.

[0029] In the embodiment of the present invention, pollution-free deep well seawater is used as aquaculture water source. The deep well is within one kilometer from the seaside. There is no industrial wastewater, no domestic s...

Abstract

The invention discloses a closed type circulating water breeding method of hexagrammos otakii. The method includes the steps of selecting a breeding water source, establishing a breeding environment, controlling the breeding density and the breeding water temperature, adjusting the breeding water quality, adjusting and controlling breeding water oxygen dissolution, selecting and putting in breeding bait, managing breeding sub-ponds, and preventing and controlling breeding diseases. An oxygen and water mixer is added to the tail end of a water processing device, an oxygen dissolution probe and an emergency gas chamber are added in a breeding pond, and an ultraviolet lamp box is communicated between a biological pond and the oxygen and water mixer. The breeding environment is controllable, closed type circulating water processing facilities are complete, the continuous optimism of the breeding environment is ensured, the water temperature is controllable, the fluctuation of the breeding water temperature is avoided, matched feed is put in, bait waste is avoided, the bait coefficient is decreased, the breeding economic benefits are improved, fish separating operation is conducted at the right moment according to the breeding conditions, polarization is avoided, the yield is increased, the breeding cycle is shortened, the time to market can be controlled, and economic benefits are improved.

Description

technical field [0001] The invention relates to a closed-type circulating aquaculture method for Otaki hexaline, belonging to the field of aquatic product cultivation. Background technique [0002] Hexagrammosotakii Jordanet Starks, also known as Hexagrammosotakii Jordanet Starks, is commonly known as yellow croaker and yellow stick. Otaki hexagram belongs to the order Scorpaeniformes, the suborder Hexagrammoidei, the family Hexagrammidae, and the genus Hexagrrammos. Otaki hexaline fish is a cold-temperate bottom fish in the coastal waters. It is active in the area near rocky reefs. It is distributed in the Yellow Sea, Bohai Sea, Japan, North Korea and the Far East of Russia. Its meat is delicious and it is called "Northern Grouper". . The body of the fish is elongated and slightly flattened, the head is small, and there is a small feathery protrusion on the back of the nape. The body is covered with small ctenoid scales, which are not easy to fall off. There are 5 latera...
