Description
Technical field
The present invention relates to a kind of artificial raise seedling method of fish seedling-cultivating method, particularly a kind of industrial Tilapia of culture fishery
Background technology
Tilapia mossambica is the Perciformes Callichthyidae, belongs to tropic fishes, has kind more than 100, and majority originates in the African continent and Middle East.Tilapia mossambica has grow fast, characteristics such as feeding habits are wide, fertility is strong, disease is few, meat is good, output height, culture the area at present and reach more than 70 countries and regions, China began to introduce the sixties in 20th century cultures, now become important cultured fishes, main breed variety has: more than 10 kinds such as Sarotherodon sp, gift tilapia, 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 China south 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 to match the mating fertilization, and after forming fertilization and incubating, raun sucks fertilized egg in the oral cavity rapidly and hatches.An about week, just hatch fry, fry spues from female lymphogranuloma inguinale, and beginning is ingested in water, is grown.Naturally Fu Hua shortcoming be female lymphogranuloma inguinale incubate the time long, the fertilized egg hatching rate is low, survival rate is low, the specification of emerging is irregular; The nature hatching pattern, the fry of collecting at last is the fry that goes out the birthday from different parents, difference, can not know clearly the affiliation of every tail fish, so genetic background is unclear, can not carry out family selective breeding.There are problems such as Tilapia mossambica parent germplasm is degenerated, fertility descends, seasonal weather restriction Sarotherodon sp breeding coverage rate obvious, high-quality is low at present, restricted the development of Tilapia mossambica industrialization.
The patent application of the existing Tilapia mossambica crossbreeding and the aspect of growing seedlings, provide " tilapia male and female pairing propagation method " as patent application 200710133195.7, selecting ripe male Tilapia mossambica and raun places net cage to match cultivation, Tilapia mossambica is carried out family selective breeding, avoid because offspring's germplasm that inbreeding produces is degenerated.Patent application 200710133194.2 provides " artificial incubation method of tilapia oosperm ", tilapia male and female pairing breeding is carried out in net cage, break the raun lower jaw into two with one's hands with forefinger, fertilized egg in the raun oral cavity is poured out, through the salt water rinse, change over to and hatch the total man worker hatching that can realize tilapia oosperm in the incubator and Tilapia mossambica is carried out family selective breeding, avoid because offspring's germplasm that inbreeding produces is degenerated.Patent application 200710040190.X provides " seeding technique of a kind of hybridization fish-Ji Ao Tilapia mossambica ", it is maternal selecting JeFu luoluo fish for use, Israel's Oreochromis aureus is a male parent, carries out the combo breeding and obtains hybrid generation, and male ratio is stable, emergence rate is high, growth is rapid, strong stress resistance.Patent application 200810029159.0 provides " industrial Tilapia seedling-raising method ", by with the cultivation fish pond draining after the Microfilter in Microfilter pond filters, the biofilter is carried out biochemical treatment and is flowed into regulating reservoir, carry out temperature, O2, pH regulator, ultraviolet sterilization system and regulating reservoir parallel running simultaneously, the outlet pipe of regulating reservoir is transported to each fishpond with treated water, promptly capable of circulationly is used to cultivate the high density Tilapia mossambica and grows seedlings.Above technology solves some link problems that the Tilapia mossambica production of hybrid seeds is grown seedlings targetedly, not enough system and comprehensive.
Summary of the invention
The object of the invention is to overcome the defective of the above technology, and a kind of artificial raise seedling method that improves the industrial Tilapia of fry quality and survival rate is provided.
In order to reach above purpose, process equipment of the present invention is provided with and filters temperature regulating device, hatching apparatus, nursery pond device, filter temperature regulating device water is carried out at least 3 layers of filtration, water quality meets pollution-free food aquiculture fresh water water quality (standard No.: NY5051-2001), the temperature of control water is that 27～29 ℃, salinity are 5～8 ‰, pH value is 6.5～8.3, oxygen content 5mg/L, enters storage cistern and connects water supply piping system and supply water to hatching apparatus, nursery pond device; Hatching apparatus comprise taper shape incubate the bucket and collecting pit, incubating barrel top is provided with opening and receives reception tank by tank, water supply line through the valve straight cutting to incubating bucket bottom, tilapia oosperm put into incubate bucket, control the flow velocity of water well by valve, allow the current microshock make the fertilized egg hatching of fully rolling, brooding time is 60～75 hours, newly hatched larvae enters collecting pit from incubating a barrel upper opening with current, carries out the sex Screening Treatment; Prelarva is sent into nursery pond, cultivates and can carry out the thick or sale breed of pond mark in 15～18 days.Tank under collecting pit, the nursery pond connects the filter temperature regulating device through reflux line, and the water that tank flows out can be sent filter temperature regulating device cycle of treatment back to and be used.
The present technique methodological science installs reasonable in designly, practical, can realize batch production production, and for large-scale farming provides seed, and the fry quality of being cultivated is good, and the survival rate height has good economic benefit.
