A kind of apple snail artificial feed and its preparation method and application

Abstract

The invention discloses an apple snail artificial feed, a preparation method and application thereof. Its steps are as follows: (1) Pick fresh wild rice stems, water hyacinth, rice seedlings, weeds and green duckweeds, chop them up, kill them, dry them, and crush them, and crush the complex vitamin B and vitamin C; (2) Mix the complex vitamins Put B and vitamin C into a beaker, add distilled water to dissolve, and use it as component A; (3) Mix well-weighed water hyacinth powder, water hyacinth powder, rice seedling powder, weed grass powder, green duckweed powder and shell powder, and use it as a component. Component B; (4) Heat and melt the agar with water, then add sorbic acid, boil, cool, and use it as component C for later use; (5) Pour component A into component B, stir evenly, then add component C, Continue to stir well, pour it into a fresh-keeping box, cool and solidify completely, and store it in a refrigerator at 4°C. The invention has the characteristics of low price, economical and practical, easy preparation and the like, and is suitable for large-scale, long-term and subculture breeding of standard test insects.

Description

technical field [0001] The invention relates to an artificial feed and a large-scale feeding method, in particular to an artificial feed for apple snails and its preparation method and application. Background technique [0002] Apple snails, also known as big bottle snails and apple snails, are native to the Amazon River Basin in South America. Around 1980, it was introduced to the Philippines and Japan as an aquatic economic animal because of its rich protein content, high nutritional content and strong reproductive capacity, and quickly spread to other countries in East Asia and Southeast Asia (Halwart, 1994). Later, due to the failure of marketization, apple snails were abandoned and spread rapidly, resulting in outbreaks and disasters, seriously endangering crop production (Naylor, 1996). In 2000, the World Conservation Union (World Conservation Union; International Union for Conservation of Nature and Natural Resources; IUCN) Expert Committee on Alien Invasive Species ...

AI Technical Summary

Problems solved by technology

At present, the artificial breeding of apple snails for testing mainly adopts natural feeds such as rice seedlings, wild rice stems, and Chinese cabbage. Natural feeds are greatly affected by the seasons, and are easy to rot and deteriorate, frequent refueling, and heavy workload. It is difficult to use natural feeds.
