Problems solved by technology

In addition, when golden pomfret is cultured in cages, the nets are soaked in seawater for a long time, and many kinds of moss and other algae will grow attached to them, which will block the mesh holes, thereby affecting the exchange of seawater inside and outside the cages, resulting in poor water quality for breeding. In the breeding environment of ...

Embodiment 1

[0010] (1) Sea area selection: In this example, the southwestern coastal area of ​​Tieshangang District, Beihai City, Guangxi Zhuang Autonomous Region is selected as the sea area for cultivating golden pomfret. The depth of the sea area is 20 meters. , The water exchange is sufficient, not affected by fresh water and pollution sources in the inner harbor, the water quality is refreshing, and the water quality environment is relatively stable in the sea area, put 50 deep-water cages, and the distance from the bottom of the cage to the bottom of the sea is 3 meters. The water quality conditions of the tested aquaculture sea area are: Salinity 25‰, water temperature 25°C-30°C, pH 7-9, transparency 8m-15m, dissolved oxygen 5 mg / L; (2) Cage preparation: the size of the cage for breeding golden pomfret is 4m×4 m x 4 m. In the deep sea area, deep-water cages made of high-strength polyethylene (PE) with a diameter of more than 20 meters are used for cultivation. Multiple cages form a n...

[0014] (1) Sea area selection: In this example, the southwestern coastal area of ​​Tieshangang District, Beihai City, Guangxi Zhuang Autonomous Region is selected as the sea area for cultivating golden pomfret. The depth of the sea area is 10 meters. , The water exchange is sufficient, not affected by fresh water and pollution sources in the inner harbor, the water quality is refreshing, and the water quality environment is relatively stable in the sea area, put 30 small cages, and the distance from the bottom of the cage to the bottom of the sea is 2 meters. The water quality conditions of the tested aquaculture sea area are: Salinity 28‰, water temperature 28°C-32°C, pH 7-9, transparency 8m-9m, dissolved oxygen 5mg / L; (2) Cage preparation: the size of the cage for breeding golden pomfret is 3m×3 M x 4 m, multiple net cages form a net row, and the distance between the net row composed of multiple net cages should be kept at 3 meters to ensure the smooth flow of water;

Abstract

The invention discloses a mixed culture method of golden pomfret. According to the mixed culture method, based on conventional culture of golden pomfret, the golden pomfret is mixed with siganid for culture; through the technical measures of sea area selection, net cage preparation and fingerling stocking, a new mixed culture mode is adopted; by utilizing the characteristic that the siganid likes algae, the siganid eats all algae attached to the netting, the problem of mesh blocking by algae is solved, and the manpower and material resources for cleaning the netting are saved; the siganid in mixed culture mainly eats the algae on the netting, and only a little feed is needed; and therefore, the culture cost is very low, and the economic benefits of the culture are increased. Meanwhile, by utilizing the characteristic that the body fluid of the siganid contains antagonistic component against melon seed worms, after the mixed culture of siganid and golden pomfret, the problem that the golden pomfret is susceptible to the melon seed worms is solved, and the harm of the melon seed worms against golden pomfret is restricted by use of biological factor, thereby killing two birds with one stone.

Description

technical field [0001] The invention relates to a mixed culture method of golden pomfret, which belongs to the technical field of seawater culture. Background technique [0002] Oval Pomfret ( Trachinotus ovatus ) is commonly known as golden pomfret. It has the characteristics of special umami taste, fast growth, simple feeding habits, suitable for high temperature, high-salt culture, etc. It is one of the main economic fishes cultured in seawater cages in coastal areas such as Guangdong, Guangxi, Hainan and Fujian. , the local fish farmers have extensively cultivated it, and the benefits are remarkable. However, in the breeding process, pests and diseases have become the main factors affecting the culture of golden pomfret, especially the small melon worm disease, which is particularly harmful. The causative agent of cucurbitosis is Cryptocaryon stimuli (seawater small cucurbit worm). When the fish body is parasitized by a large number of stimulant Cryptocaryonia, it can ...
