Marine aquaculture net cage coating for preventing shellfish colacobiosis

Abstract

The invention discloses a marine aquaculture net cage coating for preventing shellfish colacobiosis, which is prepared by mixing tung oil, asphalt, lithopone and a poisoning material, wherein the poisoning material is triphenyltin chloride or tributyltin chloride. The coating has simple preparation technology, low cost and convenient use, utilizes organic tin to obstruct and poison marine shellfish, effectively prevents shellfish colacobiosis to net cages, has good effects and does not cause undesirable effects to the growth and reproduction of fishes and shrimps.

Description

technical field [0001] The invention relates to a coating for net cages, in particular to a coating for net cages for marine aquaculture to prevent parasitism of shellfish. Background technique [0002] The use of cages to breed various seafood has the advantages of fresh seawater, less loss of breeding feed, stable output, and strong risk resistance. Foraging needs, it is easy to parasitize on the net cage to receive bait. These shellfish parasitize and reproduce on the net cage. The normal exchange of seawater inside and outside the net cage, when this happens, the net cage is generally cleaned by high-pressure water washing, but this may cause the escape or death of fish and shrimp, what’s more, due to parasitic shellfish The fish grows up gradually, and its sharp shell and the net rope of the net cage are constantly rubbing for a long time, and the effect of wind and waves can easily cut the net rope, causing the fish and shrimp cultured in the net cage to escape to the...
