Use, respectively launched in experimental group and control group the female parent population of 500 tails (600 grams/fish or more), 500 tail hero parent populations (400 grams/fish with
On), above-mentioned fish species are Larimichthys crocea, and it is 15 DEG C hereinafter, every 1 ~ 2 day feeds feed 1 time that spring, which cultivates parent population water temperature, feeding rate
It is 1 ~ 2%, when water temperature is 15 DEG C or more, feeds daily 1 time, Feeding time is that at dusk, feeding rate is 3 ~ 6%, it cultivates 1 year,
To the maintenance of net cage routinely maintenance method in 1 year breeding process, and feed, temperature of cultivation, water body are fed in breeding process
Salinity etc. is consistent, net fishing is received after cultivation 1 year, and detect to net cage, situation is as shown in the table:
| Project | Survival rate of fish fry | Etting degree | Etting breakage | Aquaculture management and net cage maintenance cost |
| Experimental group | 96% | Substantially without microorganism adhering | Without breakage | No replacement is required for full-automatic charging, etting, convenient for management |
| Control group | 88% | Larger area adhesion of microorganisms, the blocking of part mesh | There is part etting little damage in two net cages | Net cage safeguards that the replacement of etting half a year is primary, and aquaculture management is cumbersome, and cost of labor is higher once in a while |
A kind of double harvesting system high efficiency trapping systems of water field of big area seining cultivation of the invention are found out through above-mentioned experiment, fry
High survival rate, etting surface is not easy adhesion of microorganisms and other ocean rubbish, and the capacity of anti-storm of platform is strong, maintenance cost
Low, maintenance times are few, have popularization, sustainability high.
Routine operation in above-described embodiment 1,2,3,4 is well known to those skilled in the art, herein without repeating.
Technical solution of the present invention is described in detail in embodiment described above, it should be understood that the above is only
For specific embodiments of the present invention, it is not intended to restrict the invention, all any modifications made in spirit of the invention,
Supplement or similar fashion substitution etc., should all be included in the protection scope of the present invention.
