Preparation method of environment-friendly bait for pinna

Abstract

The invention discloses a preparation method of environment-friendly bait for pinna and belongs to the field of aquaculture. The method is characterized in that high quality benthic diatom is cultured by an optimized culture medium, magnetized water, green light, palm bark, a glass goldfish bowl and the like, and then the mixed bait for the pinna is prepared by taking the benthic diatom as a major component and adding a small amount of sheep manure, rabbit manure, porcine blood powder, yeast powder, corn distiller, potamogeton malaianus powder, water caltrop powder, hydrilla varticillata powder, bone tankage, earthworm powder, fly maggot powder, artemia powder, kelp powder, garlic powder, methionine, lysine, potato powder, locust powder, lucerne meal, clam worm powder, trash fish and spiral shell meat meal. The bait is scientific and reasonable in formulation, nutrient-rich and lower in cost, is used for feeding the pinna and does not pollute water, the pinna grows quickly, has a strong constitution and is high in survival rate, and the yield is increased by 160%.
