Abstract
The present invention provides a kind of artificial fecundation method of red fin jenoar, comprising the following steps: Juvenile stage, parent population cultivation net cage, parent population reinforced cultivating, sexual gland hasten parturition, be fertilized ovum collecting and hatching, the cultivation of fry；Science collocation bait of the invention and from water quality management to parent population reinforced cultivating, hastened parturition hatching by sexual gland, control the salinity and temperature of water body, so that the prelarva hatching rate hatched reaches 80% or more, survival rate reaches 90% or more.
Description
Technical field
The present invention relates to aquatic products Cultivating techniques field, in particular to a kind of artificial fecundation method of red fin jenoar.
Background technique
Red fin jenoar, scientific name: Lutjanus erythropterus (Bloch, 1790), be Lutjanidae, Lutianus one
Kind fish.Side is flat, and mouth is big, and eye is big.Body carries on the back rufous, and juvenile fish has a dark-coloured wide angled tape by dorsal fin starting point to kiss end.It is subordinate to
Lutjanidae fish, fish body is micro- to be commonly called as snapper since its body takes on a red color in flat-sided shape, for wide warm eurysaline fishes, has become in recent years
It for the new fish kind of the ground sea-farming such as Fujian, Guangdong, Hainan, and quickly grows, the demand of seed is constantly expanded.But it plants
The demand of seedling is to each place because season, temperature, cultivation etc. require different, and China area of largely bordering on the sea requires manually
Propagation method.
Summary of the invention
For mirror with this, the present invention proposes a kind of artificial fecundation method of red fin jenoar, solves above-mentioned technical problem.
The technical scheme of the present invention is realized as follows: a kind of artificial fecundation method of red fin jenoar, comprising the following steps:
(1) Juvenile stage: normal well-balanced, disease-free, energetic, the good red fin flute of gonad development of selection health, figure
Porgy is that the ratio of parent, wherein milter and raun are 1:2~4；
(2) the cultivation net cage of parent population
It is 4000~6000m in area2Sea pond in be arranged 3~5 mouthfuls of net cages, specification be 4~8m × 4~8m × 2
~4m, has abundant water resources, water nonpollution, and each net cage puts 150~230 tails in a suitable place to breed, and net cage is equipped with disengaging discharge outlet；
(3) parent population reinforced cultivating
Water quality management: 25~32 DEG C of summer water temperature, 12~25 DEG C of winter, salinity 16~35, ammonia nitrogen 0.1~0.3mg/L, it is molten
5~10mg/L of oxygen, pH value 7.0~8.0,1000~2000Lux of illumination, noise 40~65db are solved, every 5~7d changes a water, changes
Water is 20~50%, keeps water transparency in 20~40cm；
Bait is made of following parts by weight: 29~43 parts of oyster, 17~25 parts of soybean peptide, 1~48 part of Catergen, dimension life
Plain E28~52 part, 6~8 parts of spirulina polysaccharide, 12~26 parts of growth accelerator, injected volume are 3~5 times of parent population；
(4) sexual gland is hastened parturition
The parent population for having entered the yolk early development stage to gonad development carries out exogenous hormone, uses the first of 1~4mg/kg
Base testosterone and 2~8mg/kg steroid hormone androstenedione are injected every 10~15d, are continuously injected 5~8 times, so that raun
Genital gland indices reach 21.52~29.24%,
(5) fertilization ovum collecting and hatching
Male and female parent population is 20~45 in salinity in voluntarily oviposition, sperm drainage, ovum, is completed in the water body that water temperature is 20~30 DEG C
Fertilization, obtains fertilized eggs, is placed in 50~80 mesh screens and is filtered cleaning 1~3 time, removes sundries, fertilized eggs are placed on room
Hatch in interior nursery pond, water temperature is kept for 25~27 DEG C, and continuous oxygenation changes water 1~3 time, quantity of exchanged water 15~25% daily, keeps water
Body transparency in 30~50cm, addition mass ratio be 1:3~5:2~8:3~9 penicillin, bovine serum albumin, polyethylene glycol,
Seawater, additional amount are 0.2~0.3 times of fertilized eggs；
(6) cultivation of fry
It embathes fry: fry temporarily being supported to 3~5d to antisecosis and embathes 10~25min using fresh water, fry is rapid
Net cage in fishing, every 3~5d fresh water embathe fry, reach 0.5~0.8kg to fry weight, and every 13~18d fresh water embathes fry,
Reaching 1~1.2kg to fry weight, every 25~32d fresh water embathes fry, reach 1.8~2.8kg to fry weight, every 50~
80d fresh water embathes fry；
The bait of prelarva is made of following parts by weight: 25~35 parts of roe powder, concentration 22~60 parts of green alga, precious jade column powder
11~39 parts and surplus seawater, feeding volume are 1.5~3.2 times of prelarva.
Compared with prior art, the beneficial effects of the present invention are:
(1) artificial fecundation method of the invention selects the red preferable parent of fin jenoar to cultivate, parent's bait raw material group
At science, ingredient collocation rationally, and from water quality management each process conditions and breeding environment can matching coordinative, promote parent
This fish body constitution；
(2) rationally science screening drug hormone is hastened parturition by sexual gland so that parent's gonad development under conditions of artificial breeding
Maturation, control fertilization water body incubation condition, be added containing penicillin, bovine serum albumin, polyethylene glycol filtering sea, reduce sea
The surface tension of water, the floating water surface is lethal after avoiding prelarva from hatching, so that the hatching rate of parent is higher.
(3) fry is embathed by time setting, under the alternating of the flushing of fresh water and seawater hatching, enhances fish body
Immunity, and fry bait raw material is reasonably combined, bait scientific matching is mutually coordinated, promotes the appetite of prelarva, using the present invention
The prelarva hatched, growth is fast, nutrition is balanced, and immunity is strong, survival rate is high.
Specific embodiment
In order to be best understood from the technology of the present invention content, specific embodiment is provided below, the present invention is described further.
Experimental method used in the embodiment of the present invention is conventional method unless otherwise specified.
Material used in the embodiment of the present invention, reagent etc., are commercially available unless otherwise specified.
The present invention is that green alga is concentrated in fresh long day board using concentration green alga, is purchased from local aquaculture shop.
