Description

Multi-party stream impact training-based fry adaptive domestication system and method Technical Field The invention relates to the technical field of fishery cultivation, in particular to a multi-party bit stream impact training-based adaptive domestication system and method for fries. Background The poor adaptability of the fries in land-sea relay transition is still a key problem for restricting the deep-open sea cultivation. At present, the sea water fry domestication mainly has two technical schemes, namely a traditional static domestication device, wherein salinity gradient adaptation is realized through single water environment simulation, but active exercise on fry motion capability is lacking, and the sea water fry domestication mainly has two technical schemes, namely a simple running water domestication system, wherein the sea water fry is stimulated to swim by adopting unidirectional water flow, and the 'running water intensive exercise method' recorded in the encyclopedia of China can only improve the endurance of young carps, but cannot realize multidimensional motion training. In the disclosed related patent, CN219146453U (a mandarin fish seedling domestication device) only solves the problem of quick replacement of moving parts, the core domestication mechanism still depends on water flow impact in a single direction and does not relate to multi-azimuth flow field design, while the domestication technology of famous and precious fingerlings such as eleutheronema tetradactylum realizes food domestication breakthrough through bionic baits, but the fries are slow to adapt due to insufficient backflow resistance and osmotic pressure regulation in the domestication process, so that the survival rate of mariculture is low. The structural cause of the core defect of the prior art is as follows: 1. The existing device mostly adopts a unilateral or unidirectional water flow design, fish fries can only perform directional swimming exercise, the development of tail handle muscles is unbalanced, the explosive force and steering capacity are not effectively improved, and the device is difficult to adapt to a complex non-directional flow field after entering the sea; 2. Land-sea transition faults, namely salinity regulation and exercise are mutually independent, and cooperative control of gradient domestication and flowing impact strength of low-salt-medium-salt-high-salt is lacking, so that a fry osmotic pressure regulating system and a moving system cannot be synchronously adapted to marine environments; 3. The suitability is poor, the stream impact strength cannot be dynamically adjusted according to the growth stage of the fries, and the targeted design of the fries with different sizes is lacking, for example, small-size fries are easy to be impacted and injured by strong water flow, and large-size fries have insufficient exercise strength; The monitoring is lack, namely linkage monitoring of flow field parameters and the physiological state of the fish fry is not set, and the domestication process cannot be accurately and scientifically controlled, so that the domestication period is long and the success rate is unstable.
