Description
Technical field
The present invention relates to a kind of domesticating method of fish, more particularly to a kind of domesticating method of hairtail, belong to aquaculture
With technical field of transportation.
Background technology
Hairtail category spoke fin net-rope, Perciformes, Trichiuridae, hairtail category, are commonly called as opotism fish, dental strip, hairtail etc..Build is flat-sided such as
Band, in silver gray, dorsal fin and pectoral fin are light grey, and with very tiny spot, tail is in black, and head sharp-crested is big, gradual to afterbody
Attenuate, height is long 2 times, 1 meter or so of total length, is all distributed at the Huanghai Sea in China, the East Sea, the Bohai Sea, the South Sea.Its meat is thin
The tender thick thorn of delicious, meat less, it is nutritious, and its method cooked is a lot of, is one of favorite seafood of common people, and large yellow croaker,
Little yellow croaker and inkfish and the four big marine products for being referred to as China.
Nowadays, large yellow croaker, little yellow croaker and inkfish are diplomatized by scientific research, have all broken through artificial breeding technology, and hairtail is still only
So there is be dead spell from water.After it is caught from water, because of the unexpected step-down of ambient pressure, fatal change can occur in vivo
Cause death.Along with hairtail is alepidote, body surface easily abrades, and natural disposition is violent, is cut one another's throats between similar serious, is not easy people
Work is raised and train, and does not have the report of hairtail domesticating method so far, and this also turns into the bottleneck that research hairtail breeds cultivation.Therefore, it is badly in need of one
The domesticating method of the effective hairtail of kind.
The content of the invention
The purpose of the present invention is to be directed to the above-mentioned problems in the prior art, it is proposed that a kind of high hairtail of survival rate is tamed and dociled
The method of supporting.
The purpose of the present invention can be realized by following technical proposal：A kind of domesticating method of hairtail, the domesticating method
Including：

Height >=1.5m of water；
Hairtail is launched：Adjust seawater water temperature in cultivation equipment and, to 20-25 DEG C, hairtail is put into cultivation equipment；
Bait throwing in：What hairtail was put into cultivation equipment starts to feed live bait on the 3rd day, after hairtail ingest live bait it is good after, start to throw
Chilled bait is fed, with the increase that chilled bait is ingested, gradually decreases live bait, until chilled bait of all ingesting；
Daily management：During raising and train, seawater water temperature is controlled at 15 DEG C -28 DEG C in cultivation equipment, at least changes water daily 1 time,
Whole day quantity of exchanged water is 50%-100%, changes water temperature difference≤1 DEG C；
Sub-sieve：Hairtail carries out sub-sieve per 30-40 days sub-sieves 1 time by the long size of anus.
In a kind of domesticating method of above-mentioned hairtail, the cultivation equipment depth 1.8-2.5m, the circumferential center in bottom four
There is the 2%-5% gradient.There is 2%- in the preferably circular pond of cultivation equipment of the present invention or the square pond of corner cut, four circumferential center of bottom of pond portion
5% gradient, which is set, can facilitate middle blowdown, during daily management, push away bottom daily at least 1 time, keep cultivation equipment bottom to do
Only.
In a kind of domesticating method of above-mentioned hairtail, the cultivation equipment carries out disinfection before seawater is added, after sterilization
Cleaned with clear water, the seawater added after cleaning is the seawater after precipitation, sand filtration.
In a kind of domesticating method of above-mentioned hairtail, the thimerosal that uses of sterilizing is sodium hypochlorite, the secondary chlorine
The concentration of sour sodium is 30-50ppm, and the time of sterilization is 40-50h.
In a kind of domesticating method of above-mentioned hairtail, the oxygen increasing tube is nanometer aeration pipe, is layed in cultivation equipment two
Side it is diagonal, length is 1.0m-2.0m.
In a kind of domesticating method of above-mentioned hairtail, the specification that the hairtail is launched is：The long 8cm-15cm of anus, body weight
6g-45g, hairtail vigor is good, not damaged.
In a kind of domesticating method of above-mentioned hairtail, the density that the hairtail is launched is 10-20 tails/m2。
In a kind of domesticating method of above-mentioned hairtail, the frequency of the bait throwing in is daily 2-5 times, and day feeding volume is hairtail
The 5%-10% of body weight.More preferably 3 times a day, the live bait fed is preferably prawn or small fish etc. to the frequency of bait throwing in,
Chilled bait is preferably minced fillet, shrimp etc., after feeding, clears up the bait do not eaten up in time.
Described to raise and train period in a kind of domesticating method of above-mentioned hairtail, the pH of seawater is 7.8- in cultivation equipment
8.5, salinity 22-26, dissolved oxygen >=5mg/L, ammonia nitrogen≤0.3mg/L, nitrite≤0.05mg/L.
Biological characteristics of the invention according to hairtail, by selecting suitable cultivation equipment, biological feed and daily management
Method etc., solve the problems, such as that the hairtail indoor culture death rate is high, while raise and train easy to operate feasible, easy to spread, fill out
The blank of hairtail artificial domestication has been mended, has realized the important breakthrough that hairtail migrates from sea to artificial feeding environment.
