Abstract
The present invention relates to an artificial incubation method of fertilized egg of tilapia mossambica. It is characterized by that the male and female paired breeding of tilapia mossambica is implemented in net cage, then said invention adopts the following several steps: checking mouth cavity of female fish, if in the mouth cavity of female fish the fertilized eggs are existed, opening mouth cavity of female fish, taking out fertilized eggs and pouring them into a landing net; using saline water to wash said fertilized eggs and placing said fertilized eggs into an incubator; making the fertilized eggs be floated in the water of said incubator and making incubation for 2-7 days so as to obtain the tilapia mossambica fries.
Description
Technical field
The present invention relates to a kind of artificial incubation method of tilapia oosperm, the total man worker of tilapia oosperm hatching specifically belongs to the aquatic fry growing technical field.
Background technology
Tilapia mossambica is for mouthful incubating property fish, and when water temperature reached more than 22 ℃, sexually matured female, milter began the pairing breeding, the raun ovulation, and after milter row essence fertilized an egg, raun promptly sucked fertilized egg in the oral cavity and hatches.In an about week, fry can hatch.Raun spues fry this moment, and fry promptly begins to ingest in water, grow.
Because the mouth that female Tilapia mossambica will carry out about a week is incubated, raun can not ingest during this period, therefore influences growing of raun.Simultaneously, because raun dissolved in oral cavity oxygen is insufficient, the fertilized egg hatching rate is affected.In addition, during incubation, if raun is alarmed, the fertilized egg in the mouth can be spued, then these fertilized eggs will be all dead.By this hatching pattern, the fry of collecting at last can not know clearly the parent of every tail fish from different parents, so genetic background is unclear, can not carry out family selective breeding.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of artificial incubation method of tilapia oosperm, can know clearly the affiliation between offspring and the parent, set up the family of Tilapia mossambica, Tilapia mossambica is carried out family selective breeding, and can control inbreeding, avoid because offspring's germplasm that inbreeding produces is degenerated.
Main solution of the present invention is achieved in that
The artificial incubation method of tilapia oosperm of the present invention adopts following processing step:
Tilapia male and female pairing breeding is carried out in net cage, in indoor net cage, a male Tilapia mossambica and a female Tilapia mossambica matched breeding, the oral cavity of raun is checked in the pairing breeding after 7～10 days, if fertilized egg is arranged in the raun oral cavity, break the raun lower jaw into two with one's hands with forefinger, the fertilized egg in the raun oral cavity is poured in the diddle-net; Through the salt water rinse, change in the incubator; Make fertilized egg at the incubator water float, hatch; Hatched 2～7 days, fertilized egg can be hatched into fry; The fry that hatches advances in the collection container with current from the opening part on incubator top.
Described pairing breeding coolant-temperature gage: 25 ℃～32 ℃.
Described brine strength: 0.5～0.7% (percentage by weight).
Described hatching coolant-temperature gage: 27 ℃～35 ℃.
Described incubator is shaped as drum shape, and the bottom is a hemispherical, and volume is about 5～7L.
Compared with the prior art the present invention has the following advantages:
The present invention can realize total man worker's hatching of tilapia oosperm, can reduce the influence that hatching is ingested to raun; Utilization the method can be set up the family of Tilapia mossambica, and Tilapia mossambica is carried out family selective breeding; Can know clearly the affiliation between offspring and the parent, thereby can control inbreeding, avoid because offspring's germplasm that inbreeding produces is degenerated.
Description of drawings
Fig. 1 is an incubator structural representation of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
Embodiment one:
The artificial incubation method of tilapia oosperm of the present invention adopts following processing step:
The present invention mainly adopts 1 hero, the 1 female mode of joining to carry out the pairing breeding of Tilapia mossambica in net cage, pairing breeding coolant-temperature gage: 25 ℃.Check the oral cavity of raun after 7 days,, then one hand dab net if fertilized egg is arranged in the raun oral cavity, another holds raun, and forefinger is broken the raun lower jaw into two with one's hands, and (about 800) pour in the dab net with the fertilized egg in the female lymphogranuloma inguinale, through brine strength: after 0.5% rinsing, change in the incubator.There is a plastic water pipe to feed the nearly bottom of incubator in the incubator, regulates current, make fertilized egg, carry out the flowing water hatching at water float.After 5 days, fertilized egg can be hatched into fry.Incubating oosperm goes out about 700 tail fries.Hatching water temperature: 27 ℃.
As shown in Figure 1: described incubator material is a duroplasts, is shaped as drum shape, and the bottom is a hemispherical, and volume is about about 6L.One plastic water pipe feeds the nearly bottom of incubator as water inlet; An osculum is left far from top 10cm place in incubator top, connects a hard plastic tube as delivery port, and delivery port is placed a container down and is used to collect the fry that hatches, and the fry that hatches enters in the collection container with current from an opening part on incubator top.
Embodiment two:
The total man worker of tilapia oosperm of the present invention is hatched and is adopted following processing step: place 1 male 1 female Tilapia mossambica and match breeding in indoor net cage, match and breed coolant-temperature gage: 30 ℃.Check the raun oral cavity after 8 days, find fertilized egg.One hand-held dab net, another holds raun, and forefinger is broken the raun lower jaw into two with one's hands, and (about 2000) pour in the dab net with the fertilized egg in the female lymphogranuloma inguinale, behind 0.6% salt water rinse, change in the incubator.Regulate current, make fertilized egg, carry out the flowing water hatching at water float.After 5 days, incubating oosperm goes out about 2000 tail fries.30 ℃ of hatching water temperature range.The structure of incubator is seemingly with embodiment one.
Embodiment three;
The total man worker of tilapia oosperm of the present invention is hatched the following processing step of employing:
Place 1 male 1 female Tilapia mossambica and match breeding in indoor net cage, coolant-temperature gage is bred in pairing: 28 ℃.Check the raun oral cavity after 7 days, find fertilized egg.One hand-held dab net, another holds raun, and forefinger is broken the raun lower jaw into two with one's hands, and (about 1000) pour in the dab net with the fertilized egg in the female lymphogranuloma inguinale, behind 0.7% salt water rinse, change in the incubator.Regulate current, make fertilized egg, carry out the flowing water hatching at water float.After 7 days, incubating oosperm goes out about 800 tail fries.32 ℃ of hatching water temperature range.The structure of incubator is seemingly with embodiment one.
Carry out first total man worker from June 21st, 2007 and hatch by in by the end of July, 2007, hatch 105 batches altogether, the overwhelming majority is hatched the fry number more than 300 tails, maximum 2000 tails that reach.Hatch about 49000 tails of fry altogether.
