Colossoma brachypomum culture method and culture net cage

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 ...

AI Technical Summary

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 period of time

[0005] At present, to remove the moss in the net cage, it is necessary to manually use physical methods to pull the fishing net out of the water and remove it with chemical reagents. It requires many people to work together, and the work efficiency is very low. Freshwater pomfret is particularly sensitive to drugs, and the use of chemical reagents will cause freshwater pollution. Pomfret death, lower survival rate
