Abstract
The invention discloses a kind of Crab Portunus trituberculatus Larvae and cultivate feed, this feed is made primarily of the raw material of following weight portion: spirulina powder 15-25 part, shrimp med 5-15 part, dusty yeast 1-5 part, bacillus subtilis powder 1-5 part, oyster shell powder 1-5 part, micro-0.1-0.5 part, mineral matter 0.1-0.5 part, phagostimulant 1-5 part, soya-bean milk 17-25 part.Spirulina in feed of the present invention is the planktonic algae of the most eating of Crab Portunus trituberculatus Larvae, meets the feed feature of Portunus trituberculatus Miers most; Dusty yeast and bacillus subtilis powder, can regulate probio flora in swimming crab intestines body, strengthens irritability and the autoimmunity of swimming crab; Phagostimulant is pure natural plant pulvis, not containing any additive, is conducive to the appetite improving swimming crab, has significant effect to the growth rate improving swimming crab.After edible feed of the present invention, survival rate and the body weight of Portunus trituberculatus Miers all increase significantly.
Description
Technical field
The present invention relates to the feed of a kind of swimming crab, specifically, relate to a kind of Crab Portunus trituberculatus Larvae and cultivate feed, belong to field of feed processing.
Background technology
Portunus trituberculatus Miers (
portunus trituberculatus) belong to Crustachia, Decapoda, Portumidae, be the maximum and foremost ocean crab class again of China.The meat flavour of Portunus trituberculatus Miers is delicious, nutritious, since the eighties, has had a sudden rise in social status.The Portunus trituberculatus Miers that China fishes for every year is mostly for foreign exchange earning, and only have little part to be supplied to domestic market needs, due to overfishing, the natural resources of Portunus trituberculatus Miers is day by day deficient, and annual catch is difficult to the demand meeting domestic market especially.In order to make up the deficiency of natural resources, meeting the needs of domestic market, carrying out propagating artificially of Portunus trituberculatus Miers one after another both at home and abroad.
Portunus trituberculatus Miers personality is violent, very bellicose, inhabits marine site bottom, hides by day and comes out at night, have obvious phototaxis, just has mutual pincers food phenomenon, when especially occurring in shell and serious scarce bait from megalopa stage; Tradition cultivation is thrown something and fed and is frozen mixed feed that trash fish, shrimp, nutrition composition and phagostimulating effect and Portunus trituberculatus Miers do not conform to as bait, and the survival rate of swimming crab is lower, increases weight not obvious.Along with propagating artificially on a large scale, this year, the mixed feed of swimming crab more and more came into one's own, but current mixed feed is mainly based on fish meal and dregs of beans, and adding portion plant or animal protein, protein raw materials is single.
Summary of the invention
For the defect that prior art exists, technical problem to be solved by this invention is to provide a kind of feed be specifically applied in Crab Portunus trituberculatus Larvae cultivating process, not only promote that Portunus trituberculatus Miers feed reduces internecine phenomenon, and the formula of uniqueness significantly improves the weightening finish of swimming crab.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of Crab Portunus trituberculatus Larvae cultivates feed, and the raw material primarily of following weight portion is made: spirulina powder 15-25 part, shrimp med 5-15 part, dusty yeast 1-5 part, bacillus subtilis powder 1-5 part, oyster shell powder 1-5 part, micro-0.1-0.5 part, mineral matter 0.1-0.5 part, phagostimulant 1-5 part, soya-bean milk 17-25 part.
Further, described trace element is nicotinic acid, folic acid, vitamin A, vitamin C, Cobastab
2mixture, weight ratio is 1:1:1:1:1.
Further, described mineral matter is the sulfate of iron, magnesium, manganese, zinc, and weight ratio is 6:2:1:4.
Further, described phagostimulant be Kelp Powder, bovine bone powder, tangerine peel powder, degreased pupa powder any one or a few.
Further, described Crab Portunus trituberculatus Larvae cultivates feed, and the raw material primarily of following weight portion is made: spirulina powder 18 parts, shrimp med 7 parts, dusty yeast 2 parts, 4 parts, bacillus subtilis powder, oyster shell powder 2 parts, trace element 0.4 part, 0.4 part, mineral matter, phagostimulant 2 parts, soya-bean milk 19 parts.
Further, described Crab Portunus trituberculatus Larvae cultivates feed, and the raw material primarily of following weight portion is made: spirulina powder 20 parts, shrimp med 9 parts, dusty yeast 3 parts, 3 parts, bacillus subtilis powder, oyster shell powder 2 parts, trace element 0.3 part, 0.2 part, mineral matter, phagostimulant 3 parts, soya-bean milk 20 parts.
Further, described Crab Portunus trituberculatus Larvae cultivates feed, and the raw material primarily of following weight portion is made: spirulina powder 22 parts, shrimp med 11 parts, dusty yeast 4 parts, 2 parts, bacillus subtilis powder, oyster shell powder 2 parts, trace element 0.4 part, 0.3 part, mineral matter, phagostimulant 2 parts, soya-bean milk 22 parts.
The present invention also provides a kind of method preparing above-mentioned feed: spirulina powder, shrimp med, dusty yeast, bacillus subtilis powder, oyster shell powder, trace element, mineral matter and phagostimulant are combined, be put in mixer and stir, the pulvis stirred is taken out, put into container to add after soya-bean milk stirs and put into dryer, between temperature 50 C ~ 60 DEG C controlling dryer, baking time is 60min, expanded after taking out, granulation.
The present invention compared with prior art, has following beneficial effect:
(1) spirulina is the planktonic algae of the most eating of Crab Portunus trituberculatus Larvae, meets the feed feature of Portunus trituberculatus Miers most;
(2) dusty yeast and bacillus subtilis powder, can regulate probio flora in swimming crab intestines body, strengthens irritability and the autoimmunity of swimming crab;
(3) phagostimulant is pure natural plant pulvis, not containing any additive, is conducive to the appetite improving swimming crab, has significant effect to the growth rate improving swimming crab.
