The method is convenient to operate and observe, and combines the characteristics of different biological characteristics under the same culture condition, so that the condition of germs in the culture water body can be more conveniently observed and judged, and the culture survival rate of verasper variegates is improved.
Description
Technical Field
The invention belongs to the field of aquaculture, and particularly relates to a method for polyculture of verasper variegates and turbot.
Background
Verasper variegates is a cold-warm bottom fish with oval body and scales on the surface, belongs to the plaice family, the platina subfamily and the verasper genus, has eyes growing on the right side of the body, has dark brown and grey-green body color on the eye side, is often mixed with light color areas with different sizes, and has the living temperature of 4-25 ℃ and the proper water temperature of 15-23 ℃. The verasper variegates breeding mode is various, and the industrial breeding is mainly adopted. If the management is not good in the industrial culture process, diseases such as fin ulceration, body surface ulceration and the like are very easy to occur, however, as the body color of verasper variegates is grayish green or dark brown, the condition that the verasper variegates has the diseases is difficult to find through characterization observation under the condition of no detection equipment, and therefore an indicating organism easy to observe is needed to judge the condition of the bacteria in the culture water body.
Disclosure of Invention
The invention aims to solve the technical problem of providing a method for polyculture of verasper variegates and turbot, and solves the technical problem that the verasper variegates are difficult to discover by characterization observation without detection equipment.
The invention provides a method for polyculture of verasper variegates and turbot, which comprises the following steps:
the number of the released turbots accounts for 4-5% of the number of the cultured turbots, and the polyculture water quality conditions are as follows: the water temperature for cultivation is 13-23 ℃, the salinity of the water for cultivation is 14-26 per mill, the pH is 7.5-8.5, the air is continuously inflated, the dissolved oxygen is kept at 6-8 mg/L, the ammonia nitrogen is less than or equal to 0.01mg/L, and the water is changed by 4-5 water volumes every day; feeding twice a day; and selecting the size in each pool every 2 months 6 months before the culture period, and selecting the size in each pool every 3 months after 9 months.
The feeding feed is prepared by granulating and air-drying fish meal and feed fish.
And the length of the seedlings is 6-8 cm during stocking.
The pond is cleaned once every month.
The invention can find the hidden danger of the disease attack of the aquatic animals by observing the real-time state of the cultured species based on that the disease is mainly prevented and the disease is treated as the auxiliary in the aquaculture process, and the disease can be effectively prevented by timely taking the medicine. In the field of fish culture, the scales are an important part of fish organism immunity and can resist pathogenic infection to a certain extent, and under the same condition, the organism immunity of the scaleless fish is slightly lower than that of the scaly fish. The invention selects the turbot which is also the cold-warm bottom layer fish from the same aspects of culture mode, culture condition and the like, and different aspects of body color, body surface scale and the like, is suitable for the industrial culture mode with the growth temperature of 7-22 ℃ and the optimal growth temperature of 15-18 ℃, has no scale on the body surface and light gray or brown on the body surface, and is used as an indicator organism for preventing the verasper moseri disease.
Advantageous effects
The method is convenient to operate and observe, and combines the characteristics of different biological characteristics under the same culture condition, so that the condition of germs in the culture water body can be more conveniently observed and judged, and the culture survival rate of verasper variegates is improved.
Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
Example 1
Industrial cultivation of 4 Tenghua of verasper platichthys in a cultivation base of certain flatfish in the sea of the Gancirus Ganggang, wherein 1 Teng of Tenghera adopts a mixed cultivation mode of verasper platichthys and turbot, and the water quality conditions and management are as follows:
the water temperature of the breeding is 13-23 ℃, the salinity of the breeding water is 14-17 per mill, the pH is 7.5-8.5, the breeding is continuously aerated, the dissolved oxygen is kept at 6-8 mg/L, the ammonia nitrogen is less than or equal to 0.01mg/L, 4-5 water amounts are changed every day, the breeding is carried out twice every day, the fed feed is formed by fish meal and feed fish through granulation and air drying, the body length of the fingerlings is about 7cm during stocking, the size of each pond is selected every 2 months before the breeding period, the size of each pond is selected every 3 months after 9 months, and the ponds are cleaned once every month. The number of the released turbots accounts for 4-5% of the number of the released turbots, and the release density of the released turbots and the turbots is shown in table 1.
TABLE 1 stocking density of verasper variegates and turbot
The pathogenic bacteria condition in the culture water body is judged by observing the characterization condition of the turbot, and compared with a method without adopting a mixed culture mode, the survival rate of the verasper variegates is improved by 15.3 percent by adopting the mixed culture mode.
Example 2
The method comprises the following steps of industrially culturing 5 Ten thousand tail of verasper circinelloides in a certain flounder culturing base in sunshine market, wherein 1 Ten thousand tail of verasper circinelloides is cultured in a mixed mode with turbot, and the water quality conditions and management are as follows:
the cultivation is carried out at the water temperature of 13-23 ℃, the salinity of the cultivation water is 23-26 per mill, the pH is 7.5-8.5, the air inflation is ceaselessly carried out, the dissolved oxygen is kept at 6-8 mg/L, the ammonia nitrogen is less than or equal to 0.01mg/L, the water is changed 4-5 water volumes every day, the feeding is carried out twice every day, the fed feed is a turbot feed of a certain brand, the body length of seedlings is about 5-7cm during stocking, the size of each pond is selected every 2 months before the cultivation period, the size of each pond is selected every 3 months after the cultivation period, and the ponds are cleaned once every month.
