Abstract

The present invention relates to the technical field of aquaculture and particularly relates to a preparation method of a palatability-type insect powder feed for fish. Firstly, protein and various nutrient-enriched kitchen wastes are used as culture materials, the culture materials and lactic acid bacteria are mixed, the mixture is subjected to stack fermentation, and stacking is conducted at anoptimum temperature of the lactic acid bacteria, so that the lactic acid bacteria compete with other indigenous bacteria species in the kitchen wastes, the lactic acid bacteria become an advantage population in the kitchen wastes, smell-unpleasant substances produced by fermentation of the indigenous bacteria species are reduced, and thus a problem of poor self-smell of hermetia illucens caused bytaking the kitchen wastes with the smell-unpleasant substances is fundamentally avoided. In addition, the lactic acid bacteria are as a probiotic, can promote digestion of the hermetia illucens, shorten time of nutrient conversion, and improve production efficiency of the feed. In addition, an addition of the lactic acid bacteria can produce lactic acid and the production of the lactic acid can improve feed palatability.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for preparing palatable insect meal fish feed. Background technique [0002] With the increasing degree of intensification, the aquaculture industry has an increasing demand for high-quality protein sources, while traditional protein sources (such as fishmeal) have a shortage of resources, and the contradiction has become increasingly prominent. Therefore, in recent years, research on alternative fishmeal protein sources has been continuously focused at home and abroad to ensure the sustainable development of the aquaculture industry. In view of the amount of resources and availability, most of the protein used to replace fish meal comes from non-animal protein sources such as legumes, oilseeds, and grain proteins. However, there are many limiting factors in plant protein sources, such as poor palatability, amino acid Imbalance, presence of anti-nutritional factors,...
