Description
Technical field
The present invention relates to a kind of wild Odontobutis obscura hatching method, especially Odontobutis obscura Ecology factory hatching method.
Background technology
Odontobutis obscura is a kind of small-sized food meat fish of fresh water, favored by consumers because of its fine and tender taste, full of nutrition, wild
Its living environment of Odontobutis obscura is constantly on the hazard, and natural water area yield is more and more lower.As the improvement of people's living standards, market
The demand of Odontobutis obscura is increasingly increased, it is impossible to which the main reason for meeting market needs is that the incubation rate of wild state is very low, no
30% survival rate of foot.The reason for causing incubation rate low, there are a variety of situations, one, the water mo(u)ld of natural water area to be stored in fresh water extensively
In, the infection of water mo(u)ld is easily met with to fish-egg and saprolegniasis must be gone up, declines its incubation rate；Second, pond environment cannot fit
The hatching of Odontobutis obscura ovum is answered, pond bottom mud is too thick, and enviromental conditions for spawning does not possess, third, other fish in wild pond are to ovum
Directly infringement and situations such as cross-infection.Thus it is the primary of raising cultured output to solve and improve Odontobutis obscura incubation rate
Condition.
The content of the invention
It is an object of the invention to provide a kind of presence for preventing saprolegniasis, improve Odontobutis obscura of the incubation rate more than 80%
Ecology factory hatching method.
What the purpose of the present invention was achieved through the following technical solutions：The Odontobutis obscura Ecology factory hatching method include with
Lower step：
1. insulation workshop builds pond, the depth 70-90cm of tank water, pond is provided with water inlet and water outlet, water inlet and
Water outlet is same direction, same upright position, and upper and lower standoff distance is 40-60cm, keeps the micro water flowing in pond；
2. placing hard net cage in pond, hard net cage net bottom is in 20-30cm, the mesh number of net cage from basin bottom distance controlling
20-30 mesh；One layer of net of collecting seedling of basin bottom place mat, the mesh number of net of collecting seedling are 70-80 mesh, and the distance between net cage wall and pool wall are
30-40cm；
3. setting multiple inverted " t " type ovum pieces in net cage, ovum piece is made of straight panel, mounting hole and transverse slat, between each ovum piece transverse slat
Gauge is from for 8-10cm；
4. ripe parent's pairing:Male Odontobutis obscura and female Odontobutis obscura 1:30 pairs -50 pairs husky pools are placed in 1 pairing, every cube of pond
Murrel；
5. feed:Parent culture is carried out using freshwater shrimp and pseudorasbora parva before oviposition, palatability earthworm is fed once a day, after oviposition
Forbid feeding earthworm, based on freshwater shrimp and pseudorasbora parva；
6. lay eggs：Nursed and hatched by milter after oviposition, hatching water temperature steps up 26-27 DEG C, and ovum removes hero after there is eyespot
Fish, will retract twitch installed in the agitation slide plate of bottom of pond, the excreta and dirt of bottom of pond be removed by current, from water outlet stream
Go out；The amplitude of agitation cannot be excessive；
7. seedling taking：Collecting seedling in net for bottom of pond is fallen directly into after postlarva membrane, postlarva, while place mat were taken out by net of collecting seedling in every two days
New net of collecting seedling, the convenient postlarva taken out with batch same specification size.
The water inlet and water outlet of the Odontobutis obscura Ecology factory hatching method are arranged on hard net cage wall and pond
Gap position between wall, water outlet are installed on the position between hard net cage bottom and basin bottom.
The straight panel of the Odontobutis obscura Ecology factory hatching method and transverse slat intersection form hemidome.
The hard net cage bottom of the Odontobutis obscura Ecology factory hatching method and basin bottom can set it is multiple go out
The mouth of a river.
The Odontobutis obscura Ecology factory incubation method, before nursing, freshwater shrimp and pseudorasbora parva are placed on light salt brine
In sterilize, when disinfecting time 2-3 is small.
According to above technical scheme it can be seen that the present invention hatches Odontobutis obscura using Ecology mode, underground water manufacture is taken certainly
Right streams phenomenon, the oviposition of self-control ovum piece, protect fish, raising incubation rate with reference to parent.Prevent the generation of saprolegniasis first, by clean
Underground water source as pond Spawning water, intake-outlet is set, keeps the current fine motion in pond, the excreta of fish and dirt
Dirt is twitched it from water outlet discharge back and forth by stirring slide plate, keeps clean pollution-free in pond；The design of ovum piece is pond point
Multistage water environment is cut into, avoids mutually infecting；The bottom of hard net cage is laid with dish seedling net, this is for timing seedling taking, specification
Size is identical, and reduction cuts one another's throat.Ecology factory hatching method not only increases incubation rate up to more than 80%, while also improves
The quality of postlarva.
