Description
Technical field
The present invention relates to technical field of aquaculture, more particularly to a kind of red claw crayfish in-vitro hatching device.
Background technology
Red claw crayfish artificial propagation at present all uses traditional approach, i.e., female shrimp oogenesis hatching, the female shrimp isolation of oogenesis is put
Enter spawning pond, progressively deepen with the color of ovum, eyespot appendage occurs and formed, and eventually forms young shrimp and leaves parent, traditional approach
Problems with and shortcoming be present：
1. water quality can not be controlled, change of water quality is caused to be influenceed by extraneous factor change during hatching, such as water temperature.Suitable
In suitable water temperature range, temperature is higher, and brooding time is shorter.If meeting low temperature, during as little as 20 DEG C of water temperature, amplitude of variation is big, fertilization
Ovum is easy to fall off, or long water mold causes embryonic death.
2. disease can not be controlled.Embryonated egg is easily infected and taken with parent during incubation with parent in same environment
The bacterium of band, virus, parasite etc., while the pathogen such as various bacteriums, virus, parasite can also be threatened in by water body, lead
Cause shrimp seedling unhealthy, in shrimp seed rearing and not high into susceptible disease during shrimp aquaculture, survival rate.
3. gene can not be controlled.Shrimp seedling gene is unknown, can not avoid inbreeding during Selection parent after its sexal maturity, lead
Offspring is caused constantly to degenerate.
4. can not accurately know the quantity for hatching shrimp seedling, cultivation density can not be learnt and shrimp seedling size specification is without legally constituted authority
One, later stage needs constantly carry out a point pond and raised, and expend a large amount of manpower and materials, because shrimp seedling quantity is unknown, cause feedstuff feeding not
Foot, shrimp is slow-growing, or feeds excess, waste feed increase cost, polluted water, can not also estimate output.
5. incubation rate is low.Due to being caused conventional method incubation rate low by the interference of various outside environmental elements in hatching process,
It is usually no more than 30%.
