Problems solved by technology

In addition, the hairtail is a scaleless fish, its body surface is easily scratched, and it is ferocious by nature. It can kill each other seriously, and it is not easy to domesticate. So far, there has been no report on the domestication method of hairtail, which has become a bottleneck in the study of hairtail breeding.

Embodiment 1

[0022] Adopt the method of the present invention to domesticate 1256 tails of hairtail juveniles, after 65 days of domestication, 856 tails survived, with a survival rate of 68.2%. The specific domestication method is as follows:

[0023] Breeding equipment: The breeding equipment selected for domestication is a corner-cut square pond with an area of ​​36m 2 , The depth of the pool is 1.8m, and two 1.2m long nanometer oxygenation tubes are laid diagonally on the bottom of the pool, and there is a 2% slope from the bottom of the pool to the center. 3 days before stocking, use an appropriate amount of sodium hypochlorite with a concentration of 40ppm to disinfect the whole pond for 48 hours, wash it with clean water after disinfection, and then add sediment and sand-filtered seawater to a height of 1.5m.

[0024] Hairtail feeding: When feeding, adjust the water temperature in the corner-cut square pool to 24°C-25°C, and use a bucket with water to gently put hairtails with good ...

Embodiment 2

[0029] Adopt the method of the present invention to domesticate 1256 tails of hairtail juveniles, after 65 days of domestication, 837 tails survived, with a survival rate of 66.6%. The specific domestication method is as follows:

[0030] Breeding equipment: The breeding equipment selected for domestication is a corner-cut square pond with an area of ​​40m 2 , the depth of the pool is 2m, two 1.2m long nanometer oxygenation tubes are laid diagonally on the bottom of the pool, and there is a 3% slope from the bottom of the pool to the center. 3 days before stocking, use an appropriate amount of sodium hypochlorite with a concentration of 30ppm to disinfect the whole pond for 50 hours, wash it with water after disinfection, and then add sediment and sand-filtered seawater to a height of 1.8m.

[0031] Hairtail feeding: When feeding, adjust the water temperature in the corner-cut square pool to 24°C-25°C, and use a bucket with water to gently put hairtails with good vitality, no...

Embodiment 3

[0036] Adopt the method of the present invention to domesticate 1256 tails of hairtail juveniles, after 65 days of domestication, 819 tails survived, with a survival rate of 65.2%. The specific domestication method is as follows:

[0037] Breeding equipment: The breeding equipment selected for domestication is a corner-cut square pond with an area of ​​35m 2 , the depth of the pool is 2.2m, and two 1.3m long nano-aeration tubes are laid diagonally on the bottom of the pool. There is a 4% slope from the bottom of the pool to the center. 3 days before stocking, use an appropriate amount of sodium hypochlorite with a concentration of 35ppm to disinfect the whole pond for 45 hours, wash with water after disinfection, and then add sediment and sand-filtered seawater to a height of 1.9m.

[0038] Hairtail feeding: When feeding, adjust the water temperature in the corner-cut square pool to 20°C-23°C, and use a bucket with water to gently put hairtails with a vigorous, undamaged anal...

Abstract

The invention relates to a hairtail domesticating method, and belongs to the technical field of aquaculture and transportation. The domesticating method comprises the steps of culture equipment preparation, hairtail putting, bait casting, daily management and screening. According to biological characteristics of hairtail, by selecting proper culture equipment and biological bait and performing daily management, the problem that the hairtail indoor culture death rate is high is effectively solved, meanwhile domesticating operation is easy and feasible, popularization is easy, the hairtail domesticating gap is filled, and the important breakthrough that hairtail is migrated from the sea to the artificial feeding environment is achieved.

Description

technical field [0001] The invention relates to a fish domestication method, in particular to a hairtail domestication method, and belongs to the technical field of aquaculture and transportation.
