Abstract
The invention discloses a phagostimulant for fish larvae and juveniles of spotted maigre and a preparation method thereof. The phagostimulant comprises the following compositions in portion by weight: 0.05 to 0.1 portion of dimethyl-beta- propionic acid thetine, 0.1 to 0.2 portion of kanirin, 0.1 to 0.3 portion of glycine trimethylpropyl, 20 to 30 portions of inosinic acid, 25 to 35 portions of clamworm extracting solution, 1 to 5 portions of betaine, 10 to 15 portions of lactamine, 8 to 10 portions of glycin, 26 to 28 portions of internal organ powder of cuttlefish, and 1 to 3 portions of lycopene. The preparation method of the phagostimulant comprises the following steps: raw materials are weighed according to weight portions and are mixed, and then the clamworm extracting solution produced by the mixing extraction of alcohol is added into the mixture. The phagostimulant has the advantages that the phagostimulant has small using amount, apparent effect, steady sources, low price, and simple production technology, can effectively improve survival rate, reduce the waste of baits, can also improve the high temperature resistance and the anti-anoxia ability of fish, strengthen the endurance of the fish to the change of water environment, and can improve the meat quality of breed varieties.
Description
Technical field
The present invention relates to a kind of additive of spotted maigre feed, particularly a kind of spotted maigre young postlarva feeding promoting agent and preparation method thereof.
Background technology
Spotted maigre, delicious meat, nutritive value is abundant, liked by broad masses.But because the nutrition sometimes of fresh and alive biological feed is unbalanced, portable pathogenic microorganism, thus cause the seed quality to descend, have a strong impact on the breed of adult fish.Therefore, the artificial pellet of spotted maigre of exploitation high-efficiency high-quality is imperative.
Phagostimulant belongs to a kind of non-nutritive additive, in aquatic feeds, add the palatability that can improve feed in right amount, improve the bait grade, can stimulate sense of smell, vision and the sense of taste of aquiculture animal, make they accumulate in bait around, thereby improve the appetite of aquatic livestock, keep high nutrition and take in, change the situation of ingesting under disease or the stressed condition, alleviate some state of an illness, breeding fish for health provides safeguard; And can strengthen aquatic livestock to the digesting and assimilating and promote growth of artitificial food, improve feeding efficiency, shorten the time of searching for food, reduce feed waste, reduce residual bait in the water, alleviate the pollution of residual bait corruption, keep the clean of water body environment water quality.In addition, the development and use of phagostimulant can improve the local flavor of fish-meal, solve protein feeds problem in short supply, for the development and use of new feedstuff resource provide wide prospect.Some mainly is exactly to extract the composition with food calling effect with the method for chemistry from animals and plants.But many shortcomings are also arranged, and as the food ration of animal, trophic level and bait utilization are not high.Single L-amino acid or its mixture also once became the food calling additive of fishes and shrimps, but owing to not low, the top grade price of its cost is higher its use is restricted, so the phagostimulant that food calling is effective, cost is low become problem and the research and development focus that faces the needs solution.
Existing artificial micro-granulated feed is not obtained ideal effect in spotted maigre seed rearing process, this mainly is owing to compare with fresh and alive biological feed, there is big defective in the attractant of existing artificial granular bait for fish, and exist chemistry and vision to urge to ingest material in the fresh and alive biological feed, as free amino acid etc.It is exactly artificial micro-granulated feed because young postlarva not ingests that young postlarva utilizes a relatively poor major reason to artificial micro-granulated feed, and therefore, developing effective young postlarva feeding promoting agent is to improve the important step that young postlarva utilizes artificial micro-granulated feed.
Summary of the invention
The purpose of this invention is to provide a kind of spotted maigre young postlarva feeding promoting agent and preparation method thereof, promote the spotted maigre young postlarva artificial microparticle mixed feed of ingesting, reduce the production cost of growing seedlings, keep the sustainable development of spotted maigre aquaculture with this.
A kind of spotted maigre young postlarva feeding promoting agent, it contains by weight: 0.05 part to 0.1 part dimethyl-β-DMPT (DMPT), 0.1 part to 0.2 part TMAO (TMAO), 0.1 part to 0.3 part glycine front three third fat, 20 parts to 30 parts inosinic acids, 25 parts to 35 parts clam worm extracts, 1 part to 5 parts betaine, 10 parts to 15 parts alanine, 8 parts to 10 parts glycine, 26 parts to 28 parts squid visceral meals and 1 part to 3 parts tomato red.
A kind of preparation method of spotted maigre young postlarva feeding promoting agent comprises the steps:
1. take by weighing by weight: 0.05 part to 0.1 part dimethyl-β-DMPT (DMPT), 0.1 part to 0.2 part TMAO (TMAO), 0.1 part are to 0.3 glycine front three, third fat, 20 parts to 30 parts inosinic acids, 1 part to 5 parts betaine, 10 parts to 15 parts alanine, 8 parts to 10 parts glycine, 26 parts to 28 parts squid visceral meals and 1 part to 3 parts tomato red, mix, obtain intermediate product;
2. choose fresh clam worm, after smashing to pieces, with etc. the ethanol of weight mix, extracting 48 hours is evaporated ethanol fully by rotary evaporation at last, can obtain the clam worm extract;
3. take by weighing 25 parts to 35 parts of clam worm extracts, mix with intermediate product.Ethanol is that percetage by weight is 70% ethanol water.
Compared with prior art, the invention has the advantages that:
(1) use in the spotted maigre young larvae forage as feed addictive, addition (percetage by weight) only is 0.5-1.5%, measures for a short time, and effect is obvious.
(2) show through the prelarva experimental verification, obviously promote the spotted maigre young postlarva to ingest, promote growth, improved survival rate with phagostimulant of the present invention; Reduce residual bait simultaneously, help protecting environment.
(3) its raw material source of the present invention is stable, cheap, and production technology is simple.
(4) DMPT has strong luring to fish and ingests and promote mushroom effect, can also improve high temperature resistance and the anoxic ability of fish, strengthens the endurance that fish change water environment.
(5) TMAO not only has strong luring and short food effect; The adjusting of osmotic pressure in the marine animal body can also be participated in, survival rate and the anti-stress ability of aquatic livestock can be improved; Albumen is played folding effect, can improve the breed variety meat.
