Description

A kind of abalone bait and preparation method thereof
Technical field
The present invention relates to aquaculture field, be specifically related to a kind of abalone bait and preparation method thereof.
Background technology
Abalone is the monoshell mollusk in ocean, and its delicious meat is nutritious, is precious seafood delights.Approximately there are 90 kinds of Baos in the whole world, and their footprint spreads all over the Pacific Ocean, the Atlantic Ocean and the Indian Ocean.Produce in bay, China Bohai Sea is haliotis discus hannai Ino, and individuality is larger; Southeastern coast is produced cries Haliotis diversicolor, and individuality is less; Half line Bao, the sheep Bao that produce in the Xisha Islands are famous edible Baos.Due to natural output seldom, therefore expensive.Nowadays, the country that produces in the world Bao all propagates artificially in development, and China cultivates Haliotis diversicolor seedling at 20 century 70s, propagates artificially and succeeds.Traditionally, abalone breeding mainly adopts the marine algas such as sea-tangle, fragrant plant mentioned in ancient texts, Shi Water-shield, sargassum as bait, is subject to the restriction in season of these seaweed growths, and supply and the cost fluctuation of bait are large, has also restricted the sustained and rapid development of this industry simultaneously.Therefore, develop and prepare efficient Articial bait making, must become the key of this industry development.
Chinese invention patent application number is 95110304.0, mixed bait of the short long diseases prevention of a kind of abalone and preparation method thereof is disclosed, bait has animal and plant raw material and several additive, according to raw material screening, be dried, pulverize, sieve, mix, add the operations such as water stirring, moulding, oven dry and process.Solved the development along with abalone culture industry, abalone natural bait can not meet the problem of supply.
Application number is that 200710158205.2 Chinese invention patent discloses compound Chinese herb food calling and immunopotentiator for a kind of haliotis discus hannai Ino, it is characterized in that its each component weight percentage respectively: Radix Codonopsis 10%-30%; Radix Astragali 20%-30%; Dried orange peel 5%-15%; Divine Comedy 5%-15%; Hawthorn 10%-20%; Fructus Hordei Germinatus 5%-15%; Bighead atractylodes rhizome 5%-15%.The effect of this invention is to use in haliotis discus hannai Ino feed as feed addictive with overflowing, and addition is 1%-5%, cheap, raw materials enjoy stable sources; Obviously strengthen the immunity of organisms of haliotis discus hannai Ino, improve survival rate; This invention has good food calling effect, improves efficiency of feed utilization, reduces feed coefficient, alleviates harmful effect water quality being caused because of residual bait, without any harmful effect, obvious to the gaining effect of haliotis discus hannai Ino to the palatability of feed; This invention production technology is simple, easy to use.
Chinese invention patent application number is 201010112350.9, a kind of compound feed for shellfish is disclosed, protein feeds 30%-70%, energy feed 30%-50%, mineral matter 0.1%-9%, vitamin 0.001%-0.01% and composite bacillus preparation 2%-10%, consist of, crude protein content is higher than 15% homogeneous powder.
It is a kind of for processing the pre-mixing agent of shellfish active bait that application number is that the Chinese invention patent of 03116966.X discloses.By protease, the mineral elements such as iron, zinc, manganese, copper, cobalt, selenium, the material that the B family vitamins such as thiamine, riboflavin, nicotinic acid, calcium pantothenate, pyridoxamine, cobalamin, biotin, folic acid and anticorrisive agent form, the pre-mixing agent through fully mixing; For fishes and shrimps protein feeds Raw material processing, become shellfish active bait.While being processed into shellfish active bait for plant protein feed sources such as dregs of beans, Cottonseed Meal, rapeseed dregs, in above-mentioned pre-mixing agent formula, increase amylase.Premix can become macro-molecular protein, starch degradation micromolecular little peptide, amino acid and oligosaccharides, monose, promote the absorption of filter-feeding shellfish, supplementary minerals and vitamins promotes the utilization ratio of shellfish to nutriment, accelerate the growth of shellfish, can promote the growth of unicellular alga, reduce the pollution level of bait to environment simultaneously.
Wu Yongpei, Chen Changsheng, Cai Huinong etc. have compared nutritional labeling and the amino acid content of the haliotis diversicolor Reeve muscle of artifical compound feed and natural raising, simultaneously, measured the content of trace element in shell, the shell that nursing seaweed fodder is occurred splits mouth and middle damaged abnormal Bao, do trace element analysis, inquired into the reason of growth failure.[Marine Sciences, 2000,2(9): 4-6.]
Zhang Hanhua, Li Min, Zhu Changbo etc. have inquired into the impact on black Bao children Bao survival and growth of stone Water-shield, asparagus, sea-tangle, Gracilaria Tenuistipitata V. Liui, livid grateloupia and artifical compound feed.[Chinese aquatic science, 2007,14(6): 903-910]
Wang Bo, You Weiwei, king's item are willing to etc. to select 4 kinds of tangleweed Gracilaria tenuistipitatas, chrysanthemum fragrant plant mentioned in ancient texts, asparagus and sea-tangle, and research is in single bait, mixed feed, the impact on Haliotis diversicolor children Bao Shengchang, survival under 3 kinds of different modes of throwing something and feeding of bait in turn.[Xiamen University's journal (natural science edition), 2010,49(2): 286-292]
At present, abalone bait mainly adopts various fresh and alive algae, powdery algae powder bait, or the sheet bait of algae powder, fish meal and binding agent mixed-forming.There is following problem in these bait: fresh algae mainly exists the low long problem of growth cycle that causes of protein content in the process of feeding; Powdery bait exists easily and runs off, and the problem that utilization rate is low, is mainly used in young abalone culture; Sheet bait is owing to being the mixture of several composition powder, and pellet hardness is high, is difficult for imbibition, and rehydration is poor, causes the edibility of abalone poor; Exist the water dispersible of binding agent strong, poor water resistance, causes easy disintegration to be run off, and finally causes the problem that bait utilization is low simultaneously.
