Abstract
The present invention relates to a kind of seedling culture methods that more squamas shovel jaw fish comprising：(1) flowing water culture；(2) after fry hatching comes out, in hatchery after 2 days full, before opening, the water temperature for adjusting hatchery is consistent with the water temperature in outdoor seedling pond, then fry is transferred to seedling pond from hatchery；(3) feed improvement is fed with seedling.A kind of seedling culture method of more squama shovel jaw fishes disclosed by the invention has the advantages that：1. fry survival rate is increased to 40%~80%；2. fry abnormal rate declines；3. fry growth speed is fast.
Description
Technical field
The invention belongs to fish reproduction fields, and in particular to a kind of seedling culture method of more squama shovel jaw fishes.
Background technology
Jaw fish --- body is long for more squama shovels, and slightly flat-sided, the back of the body slightly swells, abdomen circle.Short, kiss is blunt, and mouth is the next, transverse fissure, bicker
Extend to the lateral margin of an outside of belly.Mandibular border has sharp keen cutin；Must be 2 pairs, the upper jaw must be superfine small, and bicker must be also very short.Dorsal fin is without hard
Thorn, outer rim are recessed slightly within.Chest scale is smaller, is embedded in subcutaneous.Body carries on the back dark brown, and abdomen is greyish white.The base portion of each scale in side has
There are crescent blackspot, dorsal fin and tail fin grey black, other each fin larks, outer rim is golden yellow, and dorsal fin and anal fin have a tangerine
Flammulation.
More squama shovel jaw fish tradition fries use flowing water culture mode culture at present, but can be divided into three kinds according to the difference of bait
Breeding way：
The first breeding way：It is whole after fry opening to be raised using mixed feed.Mode is fed to be open according to fry
When floating characteristics generally by the way of dry spread.
Second of breeding way：Animal bait defibrination, generally opening stage begin to use a period of time water earthworm,
The defibrination object of yellow meal worm etc. is fed.It is to splash to feed mode.Later stage uses mixed feed culture instead.
The third breeding way：Living body bait generally mostly uses artemia as open-mouthed bait.Feed mode：Buy artemia
Egg hatching goes out artemia larvae and launches in seedling pond.Later stage also uses mixed feed culture instead.
The place but above-mentioned three kinds of breeding way all come with some shortcomings：
The first breeding way：Survival rate is extremely low.
Since parent is wild, first filial generation wild nature is not removed, excessively poor to the adaptability of mixed feed, in this way
Survival rate is usually no more than 5%, and abnormal rate is high.
Second of breeding way：Survival rate is low, and easily sends out intestines problem.
Animal bait single varieties, unbalanced nutrition, and animal feed disinfection is not thorough, itself poor quality etc. all can be straight
Connecing leads to the death of fry, and general survival rate is 8%~12%.
The third breeding way：Survival rate is high early period, and the later stage drastically reduces.
Artemia is zooplankter inside seawater, and meeting fresh water can faint, and the cultivation generally directed to fresh-water fishes is only suitable for making early period
For open-mouthed bait, and it is of high cost, the time is short, and the hatching of artemia and the removal technology of dead ovum are most important.It is general using the method
Survival rate is between 15~20%.
