Abstract
The invention relates to a feed additive for improving the fertility of parent fish of tilapia, characterized in that the feed additive comprises the following components by weight percent: 10-20% of fish meal, 1-5% of ragworm meal, 30-40% of soybean protein isolates, 10-20% of phospholipids, 5-10% of fish oil, 5-10% of L-ascorbate-2-phosphate, 10-15% of vitamin E, 1-5% of vitamin A, 1-3% of zinc-amino acid chelate and 0.5-1% of manganese-amino acid chelate. The feed additive has the following advantages of (1) obviously improving the body condition of the parent fish of the tilapia, (2) obviously enhancing the fertility of the parent fish of the tilapia and increasing the egg laying amount of the parent fish, the egg fertilization rate, the hatchability and the survival rate of larvae and juvenile, (3) the feed additive amount only being 1-3% when the feed additive is used in the feed of the parent fish of the tilapia, (4) having no adverse effect on the feed palatability, (5) the used raw materials having stable sources, low price and simple production technology.
Description
Technical field:
The present invention relates to a kind of feed addictive, particularly relate to a kind of feed addictive that improves fertility of parent fish of tilapia.
Background technology:
Tilapia mossambica is that Perciformes Callichthyidae Tilapia mossambica belongs to, and belongs to the tropical fish, has kind more than 100, and majority originates in Africa.Tilapia mossambica has grow fast, characteristics such as feeding habits are wide, reproductive capacity is strong, disease is few, meat is good, output height.The principal item of culturing at present has: more than 10 kinds such as Sarotherodon sp, lucky good fortune Tilapia mossambica, lucky Tilapia mossambica difficult to understand.Sarotherodon sp is the offspring of Oreochromis aureus and bolti hybridization, is the main at present Tilapia mossambica kind of culturing of China.It is regional wide that the suitable Tilapia mossambica in coastal areas of southern China area is cultured, and Tilapia mossambica is cultured has huge potentiality to be exploited and advantage.
Tilapia mossambica is for mouthful incubating property fish, and when water temperature reached more than 22 ℃, sexually matured female, milter began the pairing breeding, and final embryonated egg sucks in the raun oral cavity hatches.An about week, just hatch fry, fry spues from the raun mouth, and beginning is ingested in water, is grown.
Naturally hatching has following shortcoming: brooding time is long, and the parent population breeding cycle is long; The fry hatching rate is low, and survival rate is low, and regularity is poor.Some advanced factories of growing seedlings have begun to adopt the mode of artificial incubation for this reason.Promptly adopt manual type, the embryonated egg in the raun mouth is shifted out, change the artificial incubation workshop over to and hatch.This method has shortened the breeding cycle of raun greatly, and twice egg-laying time of parent population shortened to about 15-25 days by original 30-50 days at interval.Its consequence is that the lay eggs increase of number of times has caused the parent population endotrophic to be converted into sexual cell mostly growing; And make the parent population body condition descend, and reproductive capacity weakens, and egg laying amount reduces; Institute's protonatomic mass of laying eggs is not high, all in various degree the decline of rate of fertilization, incubation rate, young postlarva survival rate.Therefore be necessary form, improve the parent population body condition, improve its reproductive capacity, thereby improve egg laying amount and ovum quality, and then improve the survival rate of rate of fertilization, incubation rate and the young postlarva of ovum through feed addictive.
Summary of the invention:
The object of the invention provides a kind of feed addictive that improves fertility of parent fish of tilapia, and it can overcome above-mentioned defective.
A kind of feed addictive that improves fertility of parent fish of tilapia, its component and percetage by weight (%) scope is respectively: fish meal, 10-20%; The clam worm powder, 1-5%; Soybean protein isolate, 30-40%; Phosphatide, 10-20%; Fish oil, 5-10%; L-ascorbic acid-2-phosphate, 5-10%; Vitamin E, 10-15%; Vitamin A, 0.5-3%; Zinc-amino acid chelate, 1-3%; Chelating amino acids manganese, 0.5-1%.
The present invention has following advantage: the parent fish of tilapia body condition is obviously improved in (1); (2) obviously strengthened fertility of parent fish of tilapia, improve its egg laying amount, ovum fertilization rate, incubation rate and young postlarva survival rate; (3) use in Tilapia mossambica parent population feed as feed addictive, additive capacity is merely 1-3%; (4) the present invention does not have any harmful effect to the feed palatability; (5) its raw material source of the present invention is stable, cheap, and production technology is simple.
The specific embodiment:
Take by weighing the 20kg fish meal, 3kg clam worm powder, 40kg soybean protein isolate, 10kg phosphatide; 5kg fish oil, 10kg L-ascorbic acid-2-phosphate, 10kg vitamin E, 0.5kg vitamin A, 1kg zinc-amino acid chelate, 0.5kg chelating amino acids manganese.These 10 kinds of materials are evenly mixed the feed addictive that is raising Tilapia mossambica fertility of parent fish.It reaches modes such as vitamin relevant with breeding and mineral matter through additional good protein, polyunsaturated fatty acid, improve the parent population body condition, improves fertility of parent fish.
Case study on implementation:
Experiment in Zhanjiang and Maoming shows; But parent fish of tilapia uses this feed addictive egg laying amount to improve 16.14%-17.83% in the breeding cycle, and the ovum fertilization rate improves 9.35%-9.68%, incubation rate improves 11.3%-15.22%, young postlarva survival rate raising 11.30-11.36%.
Zhanjiang, Maoming hybrid tilapia fish larvae culture experiment result
