AI Technical Summary

Technical Problem

Existing artificial compound feeds for marine fish farming are insufficient to effectively reduce nitrogen emissions and lower farming costs while ensuring fish growth. Furthermore, the function of chrysanthemum in reducing nitrogen pollution has not been fully utilized.

Method used

This artificial compound feed for marine fish farming uses fish meal and pork meal as animal protein sources and hives as a palatability enhancer. Fish meal accounts for 60-80% of the animal protein source, pork meal accounts for 30%, and hives accounts for 1.0% of the total feed weight, in order to reduce nitrogen pollution.

Benefits of technology

This method significantly reduces the concentrations of ammonia nitrogen and nitrite in aquaculture water, while maintaining normal fish growth performance and reducing feed costs, providing an effective way to control nitrogen pollution at its source.

Abstract

The application discloses an artificial compound feed for reducing nitrogen pollution of seawater fish culture water, which comprises an animal protein source and a feeding attractant, wherein the animal protein source is composed of fish meal and pork meal, the fish meal accounts for 60-80% of the mass of the animal protein source, and the pork meal accounts for 20-40% of the mass of the animal protein source; and the feeding attractant is fishy odor, and accounts for 0.5-2.0% of the total weight of the artificial compound feed. Compared with the artificial compound feed using fish meal as the animal protein source, the artificial compound feed not only has the same performance of maintaining normal growth of the cultured fish, but also reduces the feed cost, and more importantly, can significantly reduce the ammonia nitrogen and nitrite concentration in the cultured water, thereby providing an effective method for controlling nitrogen pollution from the feed source.
