Problems solved by technology

[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 sea, which brings great harm to the farmers. Economic losses

Embodiment 1

[0011] Get 37kg of tung oil, 35kg of asphalt, 25kg of lithopone, and 3kg of triphenyltin chloride and mix them uniformly in a reaction kettle at normal temperature to prepare the coating for marine aquaculture net cages for preventing shellfish parasitism. Soak the net rope in the net cage in the above-mentioned prepared coating, then take it out to dry and then put it into seawater for normal use.

Embodiment 2

[0013] Get 20kg of tung oil, 40kg of asphalt, 36kg of lithopone and 4kg of tributyl tin chloride and mix them uniformly in a reaction kettle at normal temperature to prepare the coating for sea culture cages preventing shellfish parasitism. Soak the net rope in the net cage in the above-mentioned prepared coating, then take it out to dry and then put it into seawater for normal use.

Embodiment 3

[0015] Take 35kg of tung oil, 30kg of asphalt, 30kg of lithopone, and 5kg of triphenyltin chloride and mix them uniformly in a reaction kettle at normal temperature to prepare the coating for marine aquaculture net cages for preventing shellfish parasitism. Soak the net rope in the net cage in the above-mentioned prepared coating, then take it out to dry and then put it into seawater for normal use.
