Problems solved by technology

[0005] However, the existing flounder farming methods generally adopt the relatively traditional shallow sea cage culture method that is highly dependent on the coastal natural environment and climate. In actual production and farming, it is easily affected by natural disasters and the growth process It has a strong seasonality and is easily affected by the decline in the quality of the coastal ecological environment, resulting in the problems of high risk of breeding, long breeding cycle and low breeding efficiency

Embodiment 1

[0075] 68,500 fish fry were invested, the survival rate reached 92.8%, and the breeding area was 500m 2 , the water depth is 5.0m, and the output of adult flounder fish is 31,400 kg.

[0076] The preset breeding indicators adopted are: temperature 25℃~30℃, pH value 7.8~8.5, salinity 26%~28%, dissolved oxygen>6mg / L, chemical oxygen demand ≤2mg / L, biochemical oxygen demand ≤ 1mg / L, inorganic nitrogen ≤0.2mg / L, non-ionic ammonia ≤0.02mg / L, active phosphate ≤0.015mg / L, coliform bacteria ≤5000 / L.

[0077] From Example 1, it can be seen that when the preset breeding index is adopted, the breeding density is 27.4 tails / m 3 After that, the survival rate of 92.8% can still be achieved.

Embodiment 2

[0079] 69,100 fry were invested, the survival rate reached 96.7%, and the breeding area was 500m 2 , the water depth is 5.0m, and the output of adult flounder fish is 31,700 kg.

[0080] The preset breeding indicators adopted are: temperature 25℃~30℃, pH value 7.8~8.5, salinity 26%~28%, dissolved oxygen>6mg / L, chemical oxygen demand ≤2mg / L, biochemical oxygen demand ≤ 1mg / L, inorganic nitrogen ≤0.2mg / L, non-ionic ammonia ≤0.02mg / L, active phosphate ≤0.015mg / L, coliform bacteria ≤5000 / L.

[0081] Among them, fresh water is used to clean the flounder fish every 20 days to 30 days.

[0082] From Example 2, it can be seen that when adopting the preset breeding index and regularly adopting fresh water to clean the flounder fish, its breeding density is 27.7 tails / m 3 After that, the survival rate of 96.7% can still be achieved.

Embodiment 3

[0084] 69,300 fry were invested, the survival rate reached 95.4%, and the breeding area was 500m 2 , the water depth is 5.0m, and the output of adult flounder fish is 32,100 kg.

[0085] The preset breeding indicators adopted are: temperature 25℃~30℃, pH value 7.8~8.5, salinity 26%~28%, dissolved oxygen>6mg / L, chemical oxygen demand ≤2mg / L, biochemical oxygen demand ≤ 1mg / L, inorganic nitrogen ≤0.2mg / L, non-ionic ammonia ≤0.02mg / L, active phosphate ≤0.015mg / L, coliform bacteria ≤5000 / L.

[0086] Among them, oxytetracycline is added to the bait, and the mass ratio of bait to oxytetracycline is 1000:1.2-2.3.

[0087] From embodiment 3, it can be seen that when adopting the preset breeding index and adding oxytetracycline, its breeding density is 27.7 tails / m 3 After that, the survival rate of 95.4% can still be achieved.

Abstract

The invention discloses a paralichthys olivaceus cultivating method. The paralichthys olivaceus cultivating method comprises the following steps of mixedly cultivating male and female parent paralichthys olivaceus to obtain paralichthys olivaceus fertilized eggs; hatching the paralichthys olivaceus fertilized eggs to obtain paralichthys olivaceus fry; washing and immersing a cultivation system by fresh water after sterilizing the cultivation system; processing natural sea water, enabling the natural sea water to reach a preset cultivation index, obtaining cultivation sea water, and injecting the cultivation sea water in the cultivation system; putting the paralichthys olivaceus fry in the cultivation system for cultivating, carrying out bait feeding and pest control and prevention, and monitoring the water quality of the cultivation sea water in real time; processing cultivation waste water, and enabling the cultivation waste water to reach the preset cultivation index so as to be used as the cultivation sea water which can be recycled; injecting the cultivation sea water into the cultivation system. The paralichthys olivaceus cultivating method disclosed by the invention is relatively environment-friendly and has smaller pollution on the environment; in addition, the paralichthys olivaceus can be cultivated by utilizing the natural sea water which can reach the preset cultivation index after being processed, the cultivation risk is lower, the cultivation period is shorter, the cultivation efficiency is higher, and the cultivation quality is better.

Description

technical field [0001] The invention relates to the technical field of cultivation, in particular to a method for cultivating flounder fish. Background technique [0002] At present, the mariculture industry has always been one of the fastest-growing industries in agriculture and the rural economy. It has created a large number of employment and income-increasing opportunities for the transfer of rural labor force, and has become an important industry to promote the development of the rural economy. Comprehensive economic development has played an important role. Therefore, vigorously developing the marine aquaculture industry is an important direction for the future development of my country's marine fishery. [0003] Among them, in the marine aquaculture industry, famous and high-quality new species and high-value-added aquaculture are important ways to rapidly develop the marine aquaculture industry. However, in fact, my country's freshwater aquaculture has always been ...
