Problems solved by technology

In the stage of psyllium larvae and mysis larvae, many live baits are used, but there are many unfavorable factors in the use of live bait: affected by environmental and management conditions, the production and quality of live bait tend to be unstable, and it is difficult to synchronize supply and demand; The cultivation of bait needs to occupy a lot of water facilities, which consumes a lot of financial resources, manpower and material resources, resulting in high seed production costs; in addition, live baits may carry pathogenic bacteria, which poses a biological safety hazard
[0004] There have been some attempts to develop artificial microparticle feeds for seedlings on the market. According to their different manufacturing processes, they can be divided into micro-adhesive feeds, micro-film feeds, and micro-encapsulated feeds, but they are all deficient in nutrition or technology. Problems such as nutritional mismatch, easy loss of nutrients, and easy water damage cannot meet the nutritional and feeding needs of shrimp larvae

Abstract

The invention relates to a microcapsule feed and a preparing method thereof, in particular to a microcapsule feed for cultivating juvenile penaeus vannamei and a preparing method thereof. The particlesize of the feed is 5-50 micrometers, and the feed is prepared from, by weight, 15-25% of white fish powder, 10-25% of squid powder, 5-10% of artemia powder, 5-10% of a fish hydrolysate, 5-10% of a clam hydrolysate, 4-8% of a yeast hydrolysate, 1-6% of schizochytrium limacinum, 2-6% of spiral seaweed, 1-2% of wall-broken haematococcus pluvialis, 3-10% of vital gluten, 5-15% of corn gluten meal, 2-5% of gelatin and the balance multi-vitamin premix and multi-mineral premix. The microcapsule feed gets rid of the passive situation that the early seedling growing production completely depends on natural baits, the situation that negative influence on the water is caused due to the use of the natural biological baits is avoided, the seedling growing cost is reduced, the survival rate is increased, the production of penaeus vannamei seedlings and the healthy development of the breeding industry are promoted, and the feed and the preparing method have important significance.

Description

technical field [0001] The invention relates to a microcapsule feed and a preparation method thereof, in particular to a microcapsule feed for cultivating Penaeus vannamei larvae and a preparation method thereof. Background technique [0002] Penaeus vannamei, commonly known as Penaeus vannamei, has quickly become the largest prawn in my country due to its large output, high meat yield, delicious meat, fast growth, adaptability to a wide range of salinity, and easy intensive farming. Breeding species. The annual demand for seedlings of Penaeus vannamei is huge. According to the 2018 Fishery Statistical Yearbook, the output of shrimp seedlings is about 400-500 billion. The supply of healthy seedlings directly affects the development of this breeding object. [0003] In the early seedling production process, live baits such as microalgae, rotifers and Artemia larvae and artificial particulate feed are mainly used to cultivate larvae. In the stage of psyllium larvae and mysis ...
