Abstract
An artificial echolic method for golden tai includes such steps as choosing two years old golden tai, culturing ever year under a certain condition, feeding zazor clam, young squid, the sex gland of squid, or eel plus VE and VC, exchanging water by 1/3 every day, and injecting the prolan after injecting anaesthetic four times at intervals of 10 days. Said prolan is sequentially luliberin A3 for the first injection, and the second injection, and the luliberin A2 another component for the third and the fourth injections.
Description
Technical field:
The present invention relates to fish reproduction technology, especially yellow porgy (Dentextumifrons) artificial propagation techniques of mariculture.
Background technology
Yellow porgy generally has only 150 grams, individual less, inhabit in the bottom marine site of depth of water 80-250m, its life habit and residing ecotope are different from freshwater fishes such as green grass or young crops, grass, silver carp, flathead, and the porgy, the yellow croaker that go up water layer during near yellowfin porgy, black porgy reaches with inhabiting littoral zone simultaneously are also different.Yellow porgy belongs to the fish that the development of ovary is asynchronous, lay eggs in batches, and be spring and autumn breeding period, is respectively 3 to May and November.The breeding of various fish is to the requirement difference of physiological ecological, and hormonal medicaments kind and dosage that the accelerating in the propagation technique is hastened parturition used have nothing in common with each other, and the yellow porgy accelerating method of hastening parturition also is different from other fish.Yellow porgy lays eggs except that being subjected to the sex steroid hormone regulation and control, and is also in close relations with envirment factors such as water temperature, illumination, salinity and flowing water.At present, the domestic and international still unmatchful report that it is specialized in.
Summary of the invention
The present invention need solve the technical problem of artificial hastening spawning of yellow porgy, for the enforcement of artificial fry nursing of yellow porgy technology provides technical guarantee.
Technical scheme of the present invention adopts 2 ages above yellow porgies to raise and train at net cage or indoor pond, and the water temperature of surviving the winter keeps 17～20 ℃, intensity of illumination 1000Lx, salinity remains on 34～35 ‰, change water 30% every day, feed adds V for the razor clam of hanging, little squid, squid sexual gland and eel feed in the eel feed
E, V
CEach 10 days at interval of yellow porgy accelerating injection of hormone carries out drug anesthesia to parent population before the injection hormone; Inject for the first time luteinizing hormone releasing hormone A
3(LHRH-A
3), dosage 5 μ g/kg, luteinizing hormone releasing hormone A for the second time
3Injected dose 10 μ g/kg, injection is for the third time selected gonad development to IV phase, cloacal aperture rubescent raun and the milter that can extrude seminal fluid, injection luteinizing hormone releasing hormone A
2(LHRH-A
2)+maleic acid DOM (DOM) hormotone, dosage 10+5mg/kg, injection luteinizing hormone releasing hormone A on the 5th at interval
2(LHRH-A
2)+maleic acid DOM (DOM) hormotone, dosage 15+5mg/kg, yellow porgy promptly lays eggs after 28 hours.
The present invention takes to control illumination, water temperature, water quality, salinity, feed, accelerating technical measures such as hasten parturition, not only yellow porgy is raised and train to cultivate and laid eggs, egg-laying period reaches 68 days, in the egg-laying period, can both reap ripe fertilized egg every day, and cultivate juvenile fish, propagate artificially for marine fish and increased new kind.
Embodiment
Technical scheme of the present invention adopts 2 ages, 3 ages or more than 3 ages, the yellow porgy parent population of the long 14cm of body, body weight 110g is raised and train at net cage or indoor cement pit, artificial induced spawning, induced spawning, keep 17～20 ℃ of water temperatures, intensity of illumination 1000Lx, salinity remains on 34～35 ‰, change water 30% every day, feed adds V based on the razor clam of hanging, little squid, squid sexual gland and eel feed in eel feed
E, V
CDaily ration of feeding 6%～9%, cultivated through 100～120 days, raise and train sexual gland developmental state in the process according to yellow porgy, yellow porgy is carried out the artificial hormone medicine hastens parturition and induces, after making parent population injection hormone, normally ingest, move about, reduce damage, before each accelerating or the oxytocic hormone injection parent population is carried out drug anesthesia; At first yellow porgy is carried out the accelerating injection of hormone, inject luteinizing hormone releasing hormone A for the first time by short gonad maturity dosage
3(LHRH-A
3), be 5 μ g/kg by the dosage of fish body per weight, carried out the luteinizing hormone releasing hormone A second time every 10 days
3(LHRH-A
3) injection, dosage 10 μ g/kg, behind the accelerating injection of hormone, again every 10 days according to yellow porgy gonad development situation, select gonad development to IV phase, cloacal aperture rubescent raun and the milter that can extrude seminal fluid, injection luteinizing hormone releasing hormone A
2(LHRH-A
2)+maleic acid DOM (DOM) hormotone, dosage 10+5mg/kg injected luteinizing hormone releasing hormone A at interval again on the 5th
2(LHRH-A
2)+maleic acid DOM (DOM) hormotone, dosage 15+5mg/kg, oxytocic hormone are injected back 28 hours yellow porgies and are promptly laid eggs.Hormotone has good accelerating and the effect of hastening parturition to the yellow porgy gonad development, the effect of hastening parturition and egg mother cell developmental condition are closely related, under the control environment condition, single kind hormone or hormotone all can impel the above egg mother cell of yellow porgy parent population diameter 400 μ m to continue to reach maturity and induced spawning, generally speaking, hormotone induces effect better, and the above hormone induction of implementing of yellow porgy parent population egg mother cell diameter 500 μ m can obtain higher spawning rate.
Claims (1)
1, the method for artificial hastening spawning of yellow porgy is characterized in that adopting 2 ages above yellow porgies to raise and train 17～20 ℃ of the water temperatures of surviving the winter, intensity of illumination 1000Lx, every day is changed water 30% in salinity 34～35 ‰, feed adds V for the razor clam of hanging, little squid, squid sexual gland and eel feed in the eel feed
E, V
CEach 10 days at interval of yellow porgy accelerating injection of hormone carries out drug anesthesia to parent population before the injection hormone; Inject for the first time luteinizing hormone releasing hormone A
