When the stake stretched into submarine, the pointed end of stake bottom can insert the seabed, inserted certain degree of depth after, can touch T shape support, made T shape support drive blend stop upwards squint, by the suppressed spring can release elasticity in the twinkling of an eye, pop out the steel fork from the pipeline, in the bed of a sea is followed in the nail, this design can directly promote whole device's stability, unrestrained ability of anti-wind, has ensured the normal operating of whole device, is applicable to shallow sea large tracts of land purse seine engineering.
Example 3:
in the actual use process of the large-area water area purse net culture double-lifting-catching system, a culture worker fixes the pile 2, can operate according to the culture and trapping requirements, puts the fish fries into a culture area for culture, firstly puts the submerged net 1 and the trapping device 9 into the water bottom when net collection is required, quickly lifts the peripheral submerged net 1 to the water surface after a plurality of intelligent bait feeding systems feed baits to attract a large number of fish swarms, and traps the fish swarms below the platform. And meanwhile, the catching mechanical cantilever slowly rises, the catching mechanical cantilever and the catching mechanical cantilever are cooperatively operated, the catching frame device slowly sinks, the plugging screen plate 8 is gradually opened to enable fish shoals to enter the catching device 9, after the frame device sinks into the water bottom, the plugging screen plate 8 is quickly closed, small fish are automatically filtered through the grading deleting a7 and automatically return to the culture sea area, the fixed platform type catching operation is completed, after catching, the catching mechanical 29 rotates leftwards and rightwards, the caught fish is placed in the grading area 20, the small fish are automatically filtered through the grading grid b and return to the culture sea area through the fish returning pipeline 27. The catching machines 29 can be arranged in plurality on the seine piles 2, or tracks can be arranged to realize a movable catching system.
Example 4:
selecting 5 groups of the purse net culture double-start catching system high-efficiency trapping system (experimental group) and 5 other culture start catching systems (control group), carrying out culture experiments in a certain culture sea area in a Zhoushan fixed sea area, putting the 10 net platforms into use at 3-4 months, respectively putting 500 female parent fishes (more than 600 g/tail) and 500 male parent fishes (more than 400 g/tail) in the experimental group and the control group, wherein the fish variety is large yellow croaker, the temperature of the parent fishes cultured in spring is below 15 ℃, feeding 1 time every 1-2 days, the feeding rate is 1-2%, when the temperature is above 15 ℃, feeding is carried out 1 time every day, the feeding time is evening, the feeding rate is 3-6%, culturing is carried out for one year, the net cage is maintained in a conventional manner in the one-year culture process, and the feeding conditions such as feed, culture, water body salinity and the like are consistent, harvesting the net after one year of cultivation, and detecting the net cage, wherein the conditions are shown in the following table:
| item(s) Eyes of a user | Fish fry Survival rate of adult Rate of change | Degree of fouling of netting | Damage of netting | Cultivation management and net cage maintenance cost |
| Fruit of Chinese wolfberry Test (experiment) Group of | 96% | Substantially free of microbial adhesion Attached with | Without damage | Full-automatic feeding and netting do not need to be replaced and managed Convenience of use |
| To pair Light block Group of | 88% | Large area adhesion is little Biological, partial mesh plug Plug for medical use | Two net cages Slight breakage of the netting | Occasionally maintaining net cage, replacing net clothes by one half year Secondly, the cultivation management is more complicated, and the labor cost is biased Height of |
The experiments show that the efficient trapping system for the large-area water area purse net breeding double-catching system has the advantages that the survival rate of fish fries is high, microorganisms and other marine garbage are not easily adhered to the surface of a net, the wind and wave resistance of a platform is strong, the maintenance cost is low, the maintenance frequency is few, and the popularization and the sustainability are high.
