The method is simpler, but the labor intensity of manual seedling picking is high, and the labor intensity is intensive; moreover, the manual fishing of the seedlings has higher requirements on the frequency of fishing the seedlings and the fishing skills of operators, if the fishing of the seedlings is incomplete, the larger seedlings which survive under the pond condition due to the baits and the like catch the smaller seedlings, so that the survival rate of the seedlings is greatly reduced. Meanwhile, under natural conditions, artificial induced spawning is not carried out, and gonad development of female fishes and male fishes is asynchronous, so that the breeding efficiency is low.
The second method is to use hormone to perform artificial spawning, and then to perform artificial fertilization on sperms and ova obtained by the artificial spawning, and then to perform artificial hatching by using a hatching device. The breeding method has certain defects, mainly because the freshwater groupers are of a type of spawning for multiple times, the efficiency of artificial spawning is low, and the spawning amount at one time is low; meanwhile, artificial fertilization is carried out by extruding mature eggs and sperms of female and male fishes, and particularly mechanical damage to the eggs to a certain extent can be generated in the artificial egg extrusion process, so that the reproduction efficiency is reduced.

After the fries in the spawning pond 1 are all led into the first cultivation pond 3, the separation net 1e is placed at the position shown in fig. 4 through the lifting rope, at the moment, the water flow direction of the system is shown in fig. 3, the valve of the transition pipe 13 is opened, because the inlet position of the transition pipe 13 is higher than the outlet position, and the interception of the separation net 1e is added, parent fishes can be led into the separation pond 2, then the extraction net 2e is taken out through the rope, so that the spawned parent fishes can be replaced, the working intensity of fishing the parent fishes for a plurality of times by a worker is reduced, and mechanical damage to the parent fishes is avoided. The parent fish and the fry are separated in time, so that the situation that the big fish eat the small fish is avoided, the traditional manual egg taking operation is avoided, the fishing workload is reduced, the production efficiency is improved, and meanwhile, the survival rate of the fry is also improved.
The individual size difference of the fries after a period of cultivation in the first cultivation pond 3 can occur, and since the groupers are meat-eating fishes, the same type of feeding can occur, so the groupers should be separated according to the individual sizes of the fries in time, at this time, the water flow direction is as shown in fig. 5, the second water drain pipe 9 connected with the first cultivation pond 3 is closed, the partition 33 is opened, so that the fries of smaller individuals positioned on one side of the partition 33 can enter the fry pipeline 8 along the water flow direction through the set screening net 36, and thus flow into the adjacent next cultivation pond 3. Separating fish fries with different sizes, avoiding the condition of mutual residual food among the fish fries, and enabling the fish fries with different sizes to enter different cultivation ponds 3 for cultivation until commercial fish fries are sold. The whole system adopts a water circulation system, so that the inside of each device is flowing water, the unit modularization is not needed for culturing the freshwater groupers on the premise of simulating the breeding condition of the groupers in the natural environment, the workload and the working strength in the freshwater groupers culturing process are greatly reduced, and the freshwater groupers breeding productivity is ensured.
