Shallow-sea breeding method capable of removing benthonic organisms and improving bottom substrate

Abstract

The invention provides a shallow-sea breeding method capable of removing benthonic organisms and improving a bottom substrate. According to the technical scheme, a net pulling cable (1), a fixing plate (2), shovel needles (3), wheel axles (4), a rotation belt (5), a collecting net (6), box bodies (7), stand columns (8) and two-wheel connection chains (9) are included. According to the shallow-sea breeding method capable of removing the benthonic organisms and improving the bottom substrate, benthonic hostile organisms are removed, benthonic subsoil looseness is improved, the survival rate of shellfish fries is increased, and key factors for health growth of young shellfish are guaranteed. Generally, after the hostile organisms are removed, the yield of shellfish can be increased; organic matter which is not oxidized in the bottom substrate is oxidized, and nutrient substances in a water area are increased, and the method is beneficial for distribution growth of the young shellfish and improving of the quality, safe, reliable and beneficial for vigorous promotion of shallow-sea breeding.

Description

technical field [0001] The invention relates to the technical field of shallow sea culture, in particular to a shallow sea culture method for removing benthic organisms and improving bottom quality. Background technique [0002] In shallow sea shellfish farming, some benthic organisms have become harmful organisms to shellfish farming. They prey on shellfish seedlings, compete with shellfish seedlings for bait and growth bases, and cause environmental water quality deterioration. They must be removed. There are two general removal methods, drug poisoning and trapping. Drug poisoning pollutes the environment; trapping requires a lot of manpower and material resources, which is costly, labor-intensive and time-consuming. At the same time, the substrate condition of shellfish life also affects its growth. If the substrate is too hard, it is not conducive to the distribution and growth of shellfish; if the substrate is too soft, the content of organic matter is high, and harmful...

Problems solved by technology

There are two general removal methods, drug poisoning and trapping. Drug poisoning pollutes the environment; trapping requires a lot of manpower and material resources, which is costly, labor-intensive and time-consuming.

At the same time, the substrate condition of shellfish also affects its growth. If the substrate is too hard, it is not conducive to the distribution and growth of shellfish; if the substrate is too soft, the content of organic matter is high, and harmful substances will be produced.
