Abstract

The invention discloses a nutrient capable of promoting the health of crusts of aquatic crustacean, as well as a preparation method and use method of the nutrient. The nutrient capable of promoting the health of crusts of aquatic crustacean comprises the following raw materials in percentage by weight: 5-25% of microelement nutrition sources and 75-95% of a synergist, wherein each kilogram of thenutrient capable of promoting the health of crusts of aquatic crustacean comprises the following microelement nutrition sources of copper, iron, zinc, manganese, iodine, cobalt, selenium, potassium, magnesium, sodium and calcium. The nutrient capable of promoting the health of crusts of aquatic crustacean integrates the functions of promoting exuviation, enriching the calcium, strengthening shells, preventing diseases and resisting stress, provides quality calcium sources and other mineral substances for the aquatic crustacean, and improves mineral substances of water bodies; the nutrient hasthe characteristics of being multiple in effects, safe, quick, high in absorption and utilization rate, convenient to use and the like; and the nutrient is directly put into the water bodies, the shells of the aquatic crustacean after exuviation can become hard quickly, the phenomenon that the shells are difficult to become hard is reduced, the nutrient has the efficacy of consolidating body resistance, strengthening bodies, defending virus invasion and promoting growth, and the survival rate of the aquatic crustacean is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a nutrient for promoting the health of the shell of aquatic crustaceans and a preparation and use method thereof. Background technique [0002] The growth of aquatic crustaceans (such as shrimps, crabs, etc.) is completed through continuous molting and hard shells, so it is necessary to absorb a large amount of mineral elements from water or feed to meet growth needs. However, in the growth of aquatic crustaceans, problems such as difficulty in molting, inability to harden the soft shell after molting, and stress diseases caused by failed molting are prone to occur. There are many reasons for this, such as: germplasm degeneration, affecting growth ;Water quality deteriorates, manifested in the fact that only half of the old shell is sloughed out or the body shrinks after the old shell is sloughed out; long-term lack of bait, showing starvation state; poor quality of feed, low...
