Abstract
The present invention discloses a Hetang murrel fry rearing method. Said method includes the following steps: incubation pond selection, selecting water for incubation, fish roe incubation, fry rearing and breeding fish fry in later atage. Said invention also provides the concrete requirements and concrete measures of the above-mentioned every step.
Description
Technical field
The present invention relates to a kind of fish seedling-cultivating method, relate in particular to a kind of Hetangli fry culturing method.
Background technology
Hetangli has another name called bamboo shoot shell fish, formal name used at school Oxyeleotris marmoratus (Oxyeleotris marmoratus) is the torrid zone, semi-tropical high-quality freshwater fish, originate in states such as Cambodia, Thailand and Vietnam, it is the high freshwater aquiculture kind of a kind of economic benefit, this fish has the breed development prospect in China south, southwest and East China, is that the more new varieties that the soft-shelled turtle industry is created high benefit are again supported in freshwater aquiculture, greenhouse.As long as resolve the seed rearing in early stage and the cultural method in later stage, then can large tracts of land promote, this fish is since the eighties is introduced China, and artificial breeding technique fails to break through, show the open-mouthed bait and the fry rearing ecology that do not solve this fish prelarva, the survival rate of prelarva is extremely low.Fail to form the mass production fry, can't satisfy the demand of aquaculture, limited the development of this fingerling aquaculture this fry.
Application number is: CN02112675.5, denomination of invention is: biological engineering and the cultural method of murrel section fish, in the spawning and fertilization process, incubating oosperm after going out small fish is pulled parent population out.Parent population is to select stabilization characteristics of genetics, and the healthy and strong anosis nothing of physique is hindered, and more than the body weight 0.75kg, the age, ripe parent population was kind of a fish more than 2 years old, and female-male proportion is 1: 1.This method has been made contribution in the research aspect the fish-egg fertilization, but to after fertilization, feeding patterns before emerging and the not further investigation of collocation of throwing in bait well enlighten for the people.
Summary of the invention
The technical problem that the present invention solves is the defective that overcomes prior art, provide a kind of method of Hetangli fry culturing mass production, and integrated cost is low, the advantage that survival rate is high.
The present invention is for addressing the above problem, and the technical scheme that is adopted is as follows:
Hetangli fry culturing method, comprise that the hatchery is selected, the hatching water is selected, hatch fish roe and prelarva are cultivated, later stage puts in a suitable place to breed, it is characterized in that: the hatch fish roe process is gathered and is adhered to the artificial fish nest of fertilized egg, behind cleaning and sterilizing in parent fish pond natural propagation season, be suspended in the hatchery, inflate to the hatchery; The prelarva cultivating process is for hatching the back the 4th～8 day, throw something and feed every day ripe yolk and aquatic products particulate feed; The hatching back was risen to throw something and feed every day and is concentrated chlorella, grid algae algae liquid on the 4th day; Hatching back the 4th～12 day, the S type of throwing something and feeding every day arm tail wheel worm; Hatching back the 13rd～20 day, the L type of throwing something and feeding every day arm tail wheel worm, cladocera and copepod larva; Hatching back the 21st～45 day, throw something and feed every day cladocera and copepoda, and carried out blowdown and Jia Shui every 2-3 days; Later stage is put process in a suitable place to breed for growing to 1～1.2cm when fry, and the body surface scale is grown and finished, and the feature speckle is clear, changes 200～400m over to
2The specification fry is cultivated in large-scale cultivation pond after 15～20 days.
The present invention further can also adopt following technical scheme:
Hatch fish roe phase gas replenishment process is in 48 hours incubation periods, and total aeration quantity is 1～1.5L/h, 48～144 hours aeration quantity 0.2～0.25L/h, and 144～192 hours aeration quantitys are 0.5L/h.
Cement pit, area 8～12m are adopted in described hatchery
2, the degree of depth 60～80cm, gas stone evenly distribute by 1.5/square metre, and aeration quantity is 0.2～1.5L/h.
Described hatching water adopts the natural pool water of transparency greater than 40cm, through quartz sand cylinder cascade filtration, enters the hatchery behind the ultraviolet sterilization, water level 50cm first, and 26～30 ℃ of water temperatures, dissolved oxygen content is greater than 5mg/L, pH value 7.5～8.5.
Each pond hangs 5～8 artificial fish nests of quantity in the described hatch fish roe, and this artificial fish nest is length 30～40cm, the plastic tube of diameter 16 or 20cm.
Feeding volume was during described prelarva was cultivated: hatching back the 4th～8 day, and every day, 3 throw something and feed 1 in ripe yolk and aquatic products particulate feed 3g filtered through 100 order tulles; The 4th～12 day, the S type of throwing something and feeding every day arm tail wheel worm secondary, density is greater than 20/ml, and water level is progressively brought up to 70cm; Hatching back the 4th～12 day, the once concentration of throwing something and feeding every day chlorella and 1: 1 mixture 3L of grid algae algae liquid, rose on the 13rd day the hatching back, the once concentration of throwing something and feeding every day chlorella and 1: 1 mixture 5L of grid algae algae liquid, algae liquid density is no less than 20,000,000/ml; Hatching back the 13rd～20 day, the L type of throwing something and feeding every day arm tail wheel worm, cladocera and copepod larva secondary, density is greater than 30/ml; Hatching back the 21st～45 day, throw something and feed every day cladocera and copepod larva secondary, density is greater than 30/ml, blowdown in per 2 days, adds water once, and aeration quantity is progressively adjusted to 1～1.5L/h by 0.5L/h.
Compared with prior art, the present invention has following technique effect:
The present invention is from the selection of hatchery, the selection and the control of hatching water, the hatch fish roe aeration quantity rationally, the rational bait and the mode of throwing something and feeding all were that the inventor sums up through test of many times in good time putting in a suitable place to breed during prelarva was cultivated, have scientific and practice value, make the seedling raising manners of hetangli low, obtain large-scale mass production under the high prerequisite of survival rate at cost.
