Problems solved by technology

[0004] Cage culture is one of the main methods of freshwater pomfret. However, during aquaculture, due to long-term immersion in water, moss is easy to grow on the nets at a depth that can be reached by light, which affects the exchange of water inside and outside the culture cages. Reduce the oxygen content in the water, thereby affecting the growth of freshwater pomfret, usually requires cleaning the nets within a certain p

Embodiment 1

[0050] A freshwater pomfret cultivation device: such as figure 1 , including a fishing net device 11, a buoyancy mechanism 10 is provided outside the fishing net device 11, the buoyancy mechanism 10 provides buoyancy for the entire cage to float on the water, and the buoyancy mechanism 10 includes buoyancy blocks 104 and buoyancy blocks arranged on both sides of the fishing net device 11 106 , the buoyancy block 104 and the buoyancy block 106 are fixedly connected with the cage device 11 , which have sufficient strength to prevent damage in wind and waves, and provide buoyancy support for the frame device 13 .

[0051] like figure 2 and image 3 , the frame device 13 supports the entire fishing net device 11 to ensure the internal space of the cage, and the frame device 13 includes a power source 201 and a telescopic mechanism 22 arranged on the left side of the fishing net 101 to control the depth of the entire cage and control the elevating mechanism 22. Adjustment mechan...

Embodiment 2

[0062] A method for culturing freshwater white pomfret in a cage, comprising the following steps,

[0063]a. Breeding conditions: Choose waters with leeward facing sun, open water surface, stable water level and fresh water quality. The pH value of the water body is 5.6-7.4, the water depth is 3-6 meters, and the most suitable water temperature is 28-30 °C. When the water temperature drops to 12 °C, most of the fish lose their balance and begin to die at 10 °C. When the water temperature exceeds 33 °C When the temperature of the water layer is different, the telescopic mechanism 22 is raised or lowered by controlling the adjustment mechanism 23, so as to control the lifting and lowering of the entire cage, so that the freshwater pomfret is in a suitable temperature water layer environment. The transparency of the water body is above 50 cm, and the dissolved oxygen is above 5 mg / L.

[0064] b. Cage setting: The cage specifications are generally length: width: depth = 4 meters ...

Abstract

The invention discloses a colossoma brachypomum culture method and a culture net cage, and relates to the field of aquaculture. According to the technical scheme, the colossoma brachypomum culture method is characterized in that the culture method for removing moss in the net cage is set according to the growth characteristics of colossoma brachypomum, and the culture method comprises the steps of a, breeding condition setting, b, net cage arrangement, c, fingerling putting, d, feed feeding, e, daily management and f, cleaning work; the invention discloses further comprises the clean culture net cage manufactured according to the culture method of the colossoma brachypomum culture method. The method and the culture net cage have the technical effects that the moss on the surface of the net cage is effectively removed, the permeability of the net cage is kept, normal exchange of water inside and outside the culture net cage is realized, the oxygen content required by the colossoma brachypomum in the water is maintained, the survival rate of the colossoma brachypomum is increased, the colossoma brachypomum grows quickly, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for culturing freshwater white pomfret and a cage device for culturing. Background technique [0002] The freshwater white pomfret is native to the Amazon River in South America. The new species introduced in recent years has a good market market due to its wide adaptability, mixed diet, fast growth, strong disease resistance, few bones and no muscle spines, and tender meat. Popular with farmers. [0003] Freshwater pomfret often lives in the middle and lower layers of the waters, likes to live in groups and swim in groups, and belongs to the middle bottom fish. Studies have shown that: the optimal growth temperature of freshwater white pomfret is 28-30 °C; when the water temperature is higher than 35 °C or lower than 20 °C, the feed intake decreases and the growth rate slows down significantly; when the water temperature drops to 12 °C, most fish The body loses its balance ...
