Problems solved by technology

Since most seawater fish are injected with oxytocin drugs, the effect time is too long or the response is inconsistent, which affects the need for large-scale production. At the same time, due to the stress response of seawater fish or the process of egg squeezing, the broodstock is often damaged, and postpartum syndrome occurs, which eventually leads to Massive death of broodstock after birth

Embodiment Construction

[0006] The invention grinds 1 gram of pentoxifylline and 1 gram of calcium dobesilate as medical raw materials (the central particle size is 200 meshes), mixes them, packs them and melts them into ampoules, each ampule is 100-400 mg.

[0007] The mutual ratio of pentoxifylline and calcium dobesilate is generally equivalent to 2 mg of pentoxifylline and 2 mg of calcium dobesilate per kilogram of parent fish, that is, the dosage of oxytocin per kilogram of broodstock is 4 mg ; Male and female fish equivalent dose.

[0008] After the oxytocic aid is dissolved in normal saline, it can be injected intramuscularly with the main oxytocic drug at the same time. The oxytocin adjuvant of the present invention is used in cooperation with LHRH-A, HCG and the main oxytocin drug of the fish pituitary gland to accelerate the performance of the oxytocin drug.

[0009] After broodstock is injected with oxytocin drugs, the pituitary gland is induced to secrete gonadotropins, and the transmissi...

Abstract

A parturition hastening accessory ingredient used for artificially propagating briny fishes relates to medicine used for artificially propagating briny fishes. The invention aims to provide accessory medicine for artificially propagating briny fishes, which enables gonadotropic hormones to more quickly act on a target organ, shortens the effect time of ripe fishes, enhances the effect on promoting the sexual maturity and accelerating maturity, improves the rate for hastening parturition and simultaneously reduces the death rate in the post-partum period of the ripe fishes. Adopting hexanone theobromine and calcium hydroxybenzosulfonate which are medical raw materials in the technical scheme, the invention is characterized in that the hexanone theobromine and the calcium dobesilate which are the medical raw materials are finely ground and uniformly mixed to form the parturition hastening accessory ingredient and is used for artificially propagating briny fishes.

Description

technical field [0001] The invention relates to a medicament for artificial reproduction of seawater fish. Background technique [0002] The drugs currently used for large-scale artificial breeding of fish are luteinizing hormone releasing hormone analog (abbreviated as LHRH-A), fish pituitary gland, human chorionic gonadotropin (abbreviated as HCG) and mixtures thereof. In the broodstock gonad maturation season, the above-mentioned or their mixtures are used for injection to arouse sexual desire and induce labor, and then perform artificial egg squeezing and artificial insemination. Since most seawater fish are injected with oxytocin drugs, the effect time is too long or the response is inconsistent, which affects the need for large-scale production. At the same time, due to the stress response of seawater fish or the process of egg squeezing, the broodstock is often damaged, and postpartum syndrome occurs, which eventually leads to Postpartum broodstock die in large numbe...
