Abstract
Disclosed is a phagostimulant for sole larvae which comprises inosinic acid, clam worm extract, oxyneurine, alanine, arginine and Sunset yellow by the weight ratio of 25-35, 25-35, 15-20, 10-15, 8-10 and 1-3.
Description
Technical field
The present invention relates to a kind of feed addictive, particularly relate to a kind of phagostimulant of sole larvae.
Background technology
At present, the sole class has become the novel kind in China's culture fishery, all is the famous and precious kind of China as Cynoglossus semilaevis, expanded letter tongue sole etc.Because it is individual greatly, growth is rapid, meat flavour is delicious, is described as " noble fish ".In recent years, the artificial propagation of sole classes such as Cynoglossus semilaevis is succeedd, and its aquaculture has also obtained rapid popularization.Yet in the cultivating process of sole class, remain fresh foods such as relying on wheel animalcule and halogen worm, this has not only improved seedling cost greatly, and since fresh food have nutritional imbalance sometimes, carry shortcoming such as germ, thereby caused the seed quality to descend, have a strong impact on the breed of adult fish.In this case, exploitation sole larvae micro-granulated feed is imperative.
Sole larvae has the characteristics slowly of ingesting, and its grazing rate is relatively low.And artificial micro-granulated feed attractant for fresh and alive biological feed is relatively poor, therefore, must develop out effective sole larvae phagostimulant.Adding phagostimulant in artificial micro-granulated feed not only can make animal obtain feed in the short period of time and the bait behavior is taken the photograph in promotion, reduce food consumption, and phagostimulant can also promote the secretion of digestive ferment, improve the digestion and absorption function of sole larvae, thereby promote survival of Cynoglossus semilaevis postlarva and growth.
Summary of the invention
The purpose of this invention is to provide a kind of sole larvae phagostimulant, it can promote the sole larvae artificial microparticle mixed feed of ingesting, and reduces the production cost of growing seedlings, and keeps the sustainable development of sole class aquaculture, to satisfy the demand of prior art.
A kind of sole larvae phagostimulant, it is characterized in that being made up of the yellow institute of inosinic acid, clam worm extract, betaine, alanine, arginine and the setting sun, their percetage by weight scope is respectively: 25-35,25-35,15-20,10-15,8-10 and 1-3.
The preparation method of above-mentioned phagostimulant is characterized in that taking by weighing inosinic acid, betaine, alanine, arginine and setting sun Huang, and these five kinds of compositions are worn into fine powder (crossing 500 orders), mixes in mixer then, adds the clam worm extract again.
The present invention has following advantage: use as feed addictive in the sole larvae feed (1), and addition (percetage by weight) only is 0.5-1.5%; (2) obviously promote sole larvae to ingest, promote growth; Reduce residual bait simultaneously, help protecting environment; (3) can increase substantially the survival rate of sole larvae; (4) its raw material source of the present invention is stable, cheap, and production technology is simple.
The specific embodiment
Embodiment 1: take by weighing yellow 1 kilogram of inosinic acid 25kg, betaine 15kg, alanine 15kg, arginine 10kg and the setting sun respectively, these five kinds of compositions are worn into fine powder (crossing 500 orders), in mixer, mix (requiring the coefficient of variation≤5%) then, add 34 kilograms of clam worm extracts again, be the phagostimulant of sole larvae of the present invention.Clam worm extract preparation method wherein is: take by weighing a certain amount of fresh clam worm, after smashing to pieces, ethanol water extracting 48h by adding 70% (percetage by weight) at 1: 1 evaporates the second alcohol and water fully by rotary evaporation at last, can obtain the clam worm extract.
Carry out the Cynoglossus semilaevis postlarva 18 days～December 18 November in 2004 (initial weight: 0.82 ± 0.02g) cultures in the Jiangnan, Qingdao, do not add phagostimulant of the present invention in the control group feed (3 repetitions), simultaneously in contrast with a kind of commercial feed (day clear feed).Add the sole class phagostimulant (product of the present invention) of 0.5% (percetage by weight) in the experiment feed (3 repetitions), behind 30 days raising experiment, discovery throw something and feed the experiment feed Cynoglossus semilaevis postlarva average survival be 29.3%, specific growth rate is 5.08%/day, is significantly higher than control group (16.3% and 4.69%/day) and commercial feed group (26.3% and 4.86%/day).
Embodiment 2: take by weighing yellow 3 kilograms of inosinic acid 35kg, betaine 20kg, alanine 9kg, arginine 8kg and the setting sun respectively, these five kinds of compositions are worn into fine powder (crossing 500 orders), in mixer, mix (requiring the coefficient of variation≤5%) then, add 25 kilograms of clam worm extracts again, be the phagostimulant of sole larvae of the present invention.
Carried out the Cynoglossus semilaevis postlarva (initial weight: 0.82 ± 0.02g) culture experiment has obtained the result similar to embodiment 1 by adding this phagostimulant in the Jiangnan, Qingdao in 2004.
Claims (2)
1, a kind of sole larvae phagostimulant, it is characterized in that being made up of the yellow institute of inosinic acid, clam worm extract, betaine, alanine, arginine and the setting sun, their percetage by weight scope is respectively: 25-35,25-35,15-20,10-15,8-10 and 1-3.
2, the preparation method of the described phagostimulant of claim 1 is characterized in that taking by weighing inosinic acid, betaine, alanine, arginine and setting sun Huang, and these five kinds of compositions are worn into fine powder, mixes in mixer then, adds the clam worm extract again.
