The device of the present invention is operated one month before the domestication, the normal amount of seawater is added into the domestication pond 1, and 50g/m of seawater is added3The seawater nitrobacteria is characterized in that 1 small 2X 1m net cage is placed in a domestication pond, 50 tips of 20cm of jewfish are put in the net cage, and the seawater nitrobacteria are fed for 1 time every day by a satiation method (8: 00 in the morning). And monitoring the changes of ammonia nitrogen, nitrite and pH value in the domestication pond every day. After 30 days, the water quality indexes in the domestication pond comprise ammonia nitrogen, nitrite and stable pH, and the small net cages and the acutangular bass are moved out of the domestication pond. Thus, the domestication and cultivation of the juvenile tuna of the yellow fin can be carried out.
Capturing wild young tunas of the tuna yellowfin, which have the body length of 22-45 cm, in the overseas of the autonomous county of the Li nationality of the Ling-fishing mode, transporting to a domestication workshop, and adding 20ppm of hydrogen peroxide into a transport barrel in the transportation process. And (4) transporting the wild tuna larvae of the yellow fin to a trial culture workshop at 4-6 pm. After the young fishes are transported to a workshop, the young fishes are directly thrown into a domestication pond with water. And (3) moving the juvenile fish into the domesticating pond for the first time, and keeping the lamplight irradiation for 72 hours. And (3) starting domesticating the feed after the juvenile fish enters the domesticating pond for 72 hours: cutting the frozen fresh trash fish meat into strips with the length of 3cm and the width of 1cm, and throwing 3 strips each time for training the young fish to eat. 8 in the morning: 00, domestication is started, domestication is performed for 4 hours in the afternoon, and young fishes enter the domestication pond for 72 hours and then begin to actively feed.
And the illumination after 72h is changed into 14h illumination: dark for 10 h. After the young fishes enter the domestication pond for 6 days, domestication is completed, and then bait feeding is changed into a satiation method of 8 in the morning: feeding for 1 time 00.
The water temperature is 28 ℃, the ammonia nitrogen is less than 0.02mg/L, and the nitrite is less than 0.05mg/L in the domestication process. Dissolved oxygen >5.8 mg/L.
Comparative example 1
The same as example 1 was repeated except that the lighting unit was not used for supplementary lighting.
The results of statistics of survival rates of young wild tuna finches according to the methods of example 1 and comparative example 1 are shown in fig. 7. As can be seen from FIG. 7, 72h of light irradiation is required to improve the survival rate of the young tunas in the early stage of domestication and breeding of the young wild tunas. After the wild juvenile fish enters the domestication pond for the first time, the survival rates of the light and the dark are respectively kept to be 95.3 +/-1.5% and 41 +/-4.51% in the evening. Therefore, the survival rate of the juvenile fish can be obviously improved by keeping the light irradiation after the wild juvenile fish enters the system for the first time. The survival rate of example 1 after the young fish enters the domestication pond at 2d was 87.9 + -1.3%, while the survival rate of comparative example 1 was 32.5 + -8.5%. From day 4 onwards, example 1 survival rates remained between 81.8% and 80.5% without significant difference. Based on survival rate data, the domestication and culture method provided by the invention has the advantages that after juvenile fish enter the system for 72 hours, the natural illumination period, namely 14 hours of illumination, is recovered: and the fish larvae are dark for 10 hours and are used for ensuring the survival rate of the juvenile fish in the domestication system.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
