Description

Swimming training device and method for flounder fishes for improving body resistance

Technical Field

The invention relates to a fish training device, in particular to a flounder fish swimming training device for improving the resistance of fish bodies and a method for training by using the device.

Background

The flounder is the same city of many flatfish species, the morphological development is very rare, the flounder is in a bilateral symmetry form as the rest of the fish species at birth, one side begins to be thinned after a few days, so that the eyes of the side finally reach the upper side of the fish, the flounder is single-sided and lies on the sea floor when in daily perching due to the special structure of the flounder, in the breeding and releasing process of the fish fries, the fish fries are artificial breeding, the movement resistance of the fries is weak, the environment change is not easy to adapt after releasing, and the death rate is high.

If the constitution of the flounder can be improved before the flounder is proliferated and released, the problems can be effectively avoided. Conventionally, antibiotics, feed additives and the like are generally added into a seedling raising pond to improve the immunity of the fish body, and the aim of improving the immunity of the fish body is fulfilled by external elements or medicines, so that medicine residues are inevitably present. The traditional method for forcing the fishes to continuously swim in the seedling raising pond to improve the self resistance is difficult to directly apply to the cultivation and training of the flounder fishes, because the habit of the flounder fishes is benthonic, the flow velocity of water flow near the bottom of the cultivation pond can be greatly slowed down, and the flounder fishes cannot make corresponding movements due to the flow of the water flow.

Compared with the prior art, the invention has the following advantages:

The swimming training device in the structural form is designed for the special habit of the flounder fishes, the special structure capable of enabling the netting to continuously do the wavy fluctuation motion is designed, the motion is matched with water flow with a certain flow speed, the flounder fishes habitually inhabiting the bottom of a water body can be forced to swim against the direction of the water flow, and meanwhile, the flounder fishes can continuously swim in the cultivation period by being matched with a specific training method, so that the aim of enhancing physique is achieved. The method does not need to feed antibiotics and additives, not only can save cost, but also can fundamentally avoid medicine residues, and has remarkable progress compared with the traditional method. Therefore, the novel water purifier has various advantages, is particularly suitable for popularization and application in the field, and has very broad market prospect.
