Micro-capsule starter feed for trachinotus ovatus fries and preparation method of micro-capsule starter feed

Abstract

The invention provides a micro-capsule starter feed for trachinotus ovatus fries and a preparation method of the micro-capsule starter feed. The micro-capsule starter feed comprises 20-25 parts of fish meal, 15-20 parts of artemia powder, 8-10 parts of microalgae powder, 0.6-1.0 part of a fermented flammulina velutipes bacterial liquid, 1.0-1.5 parts of fermented flammulina velutipes rod residues,3-5 parts of micronized bean dregs, 0.5-1.5 parts of a compound probiotic bacteria liquid, 0.1-0.5 part of lecithin, 2-6 parts of soybean oil, 1-3 parts of water chestnut powder,3-5 parts pf lotus root powder, 0.3-0.5 part of xanthan gum, 1-2 parts of sodium alginate and 15-25 parts of water. All the raw material components are scientifically blended, and sufficient nutritional ingredients are provided for the fries; and the feed is high in suspension stability, low in nutrient loss, high in food calling performance and high in digestibility and absorbability, the utilization rate of the feedby the fries is guaranteed, the start ratio and the growth effect are improved, the resistance is enhanced, healthy growth of the fry is promoted, the survival rate is high, and the water environmentis kept.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a microcapsule opening bait for golden pomfret fry and a preparation method thereof. Background technique [0002] Golden pompano, formally known as Trachinotus ovatus (Trachinotusovatus), belongs to one of the famous and precious high-grade edible marine fishes and has high economic value. With the breakthrough of golden pomfret breeding technology, artificial large-scale breeding has been developed rapidly. It has the characteristics of fast growth and short breeding cycle, and has good economic benefits in the field of aquaculture. But at the same time, with the continuous expansion of the scale of artificial breeding, the demand for golden pomfret seedlings has risen rapidly, and in the process of golden pomfret seedling cultivation, it is often limited by the difficulty of opening the golden pomfret fry. The poor stability of pomfret bait and the low utilization rate of...

Problems solved by technology

But at the same time, with the continuous expansion of the scale of artificial breeding, the demand for golden pomfret seedlings has risen rapidly, and in the process of golden pomfret seedling cultivation, it is often limited by the difficulty of opening the golden pomfret fry. The poor stability of pomfret bait and the low utilization rate of bait nutrition by fry lead to low controllability of fry cultivation, high nutrient loss rate, uneven seed quality, water pollution by bait, disease of fry, low survival rate, etc.
