Feed for artificial breeding of bullacta exarata and preparation method thereof

Abstract

The invention discloses a feed for artificial breeding of bullacta exarata. The feed is prepared from, by weight, 21 to 25 parts of flour, 10 to 13 parts of soybean meal, 7 to 9 parts of corn flour, 5to 10 parts of squid powder, 8 to 12 parts of silkworm cocoon powder, 4 to 6 parts of shrimp shell powder, 3 to 8 liver powder, 25 to 28 isochrysis galbana, 17 to 22 parts of chaetoceros, 15 to 19 parts of euphorbia thymifolia, 2 to 9 parts of artemisia argyi, 1 to 6 parts of bidens pilosa, 11 to 15 parts of calcium dihydrogen phosphate, 7 to 13 parts of zeolite powder, 1 to 4 parts of montmorillonite, 1 to 4 parts of bentonite, 3 to 6 parts of choline chloride, 5 to 7 parts of betaine, 16-22 parts of percarbonamide, 6-10 parts of methyl cellulose and 7-9 parts of complex minerals. The feed can improve the survival rate of the artificial breeding of the bullacta exarata, shorten the breeding time of the bullacta exarata, and increase the yield of the bullacta exarata.

Description

technical field [0001] The invention relates to the field of mud snail culture. More specifically, the present invention relates to a feed for artificial breeding of mud snails and a preparation method thereof. Background technique [0002] Mud snail belongs to mollusk phylum and genus Mud snail. It is widely distributed in the north and south coasts of China. It is a typical benthic reptile in the intertidal zone. Especially dense in bays with slow tides. The snail body is rectangular, the head plate is large and thick, and the mantle is underdeveloped. The lateral feet are well developed, covering part of both sides of the shell. The shell is oval, the larval shell is thin and brittle, the adult is hard and white, the surface seems to be carved with spiral rings, the inner surface is smooth, there is a yellow-brown skin, no snail tower and navel, and no horn. Because the mud snail meat is refreshing and rich in protein, calcium, phosphorus, iron and multivitamins, the ...

AI Technical Summary

Problems solved by technology

Because the mud snail meat is refreshing and rich in protein, calcium, phosphorus, iron and multivitamins, the mud snail meat can be preserved for a long time after being processed into canned mud snails by salting and wine soaking. Therefore, mud snails are sold in some large and medium-sized cities. The price is tight and expensive, but the existing mud snail breeding technology is not perfect, and the output of mud snails cannot fully meet the market demand
