Embodiment Construction

[0017] The key to raising aquatic animal seedlings is to provide high-quality feed, improve the survival rate of seedlings, and reduce the production cost of seedlings.

[0018] The ingredients, formula and preparation method of the present invention are described in detail below: First, according to the nutritional requirements of larvae such as prawns, we have selected various animal and plant powders, animal pulp, spirulina, fish oil, and seaweed for feed types and nutritional components. Polysaccharides, cholesterol, lecithin, chitosan and various vitamins and mineral elements are selected from the test to select the best solution. The following are the screening tests carried out through 7 kinds of formulations with different ingredient ratios. The test formulations and results are shown in Table 1 and Table 2.

[0019] As can be seen from the test results, 2 groups (No. 2 side) and 5 groups (No. 5 side) seedling survival rate are higher, slightly inferior to the control ...

Abstract

A bittern worm tablet as the feed of young prawn is prepared from powdered material, bittern worm pulp, fish paste, fish oil, minerals, vitamines, cholesterol, lecithin, chitosan, polymycose and spirulina through superfine pulverizing, proportionally mixing, colloid grinding, homogenizing and tabletting. Its advantages are high effect, low cost and no pollution to water.

Description

technical field [0001] The invention belongs to an artificially compounded microparticle feed for breeding aquatic animal larvae, and is a technology for preparing artemia shrimp chips that simulates the nutrition and properties of natural animal feed (artemia nauplii). Background technique [0002] Before the present invention was made, the larvae of aquatic animals were cultivated, and live artemia nauplii were first used as feed for feeding. Due to the unstable production of Artemia eggs and the high price in the early stage, researchers and aquaculture experts began to study substitutes (such as milk powder, egg yolk, soybean milk, etc.) to replace part of Artemia nauplii to cultivate aquatic animal larvae. By the eighties of the 20th century, began to study artificially compounding micro-particle feeds, there were bonded micro-particle baits, micro-particle encapsulated feeds, etc., which had better seedling raising effects than milk powder, egg yolk, etc. (survival rat...
