Description
Technical field
The invention belongs to ecological water conservancy project technical field, be specifically related to a kind of packaged type demersal fishes and lure acquisition means and method.
Background technology
The development of the nearly many decades of China's river construction, while bringing tremendous economic interests and social benefit, the ecotope of also depending on for existence on us causes and affects significantly.Especially the building of barrage building, directly blocks former river course, destroys the normal communication between material in natural water area, energy, biocoenosis, causes that river is connective constantly to decline.
For solving the problem, from last century, starting Foreign Experience, attempting having built a collection of fish pass structure based on fish pass.But in the engineering operation of reality, the operational effect of fish pass structure is not very desirable, and a lot of fish pass has to go out of use because result of use is not good.In the last few years, domesticly fish lift has been attempted again, the various new fish pass structures such as boat for collection and transportation of fish.But no matter be which kind of fish pass structure, namely affect its key factor crossing fish effect is that can Fish of interest find the import of tracing back passage.Especially in the section based on benthic fishes, how to lure that shoal of fish migration is to fish gathering region into, a great problem urgently to be resolved hurrily in engineering especially.
Fish pass structure is entered for impelling more Fish of interest, and then successfully traced back its history of life, have employed both at home and abroad to lure in a large number and drive fish measure, comprising sound, optical, electrical, gas and current in interior non-structural measure with lead fishing net, the structural type facilities such as waterpower grid.Wherein, current attracting be utilize fish side line perception water (flow) direction and fish in migration process upstream characteristic to reach a kind of technological means helping fish to cross dam object.It is feasible as one, and energy-conservation attracting mode, has application in engineering at home and abroad more.
But it is comparatively large that traditional current attracting means or measure are often subject to the impact of local flow condition, and flow control is restricted, there is water consumption large, the defects such as fish gathering scope is little.
In publication number CN102524146A, disclose a kind of oceanic pasture fish lure acquisition means, what it mainly utilized the mode of acoustic control to carry out fish lures collection, the shortcoming existed is that its apparatus structure is comparatively complicated, be only applicable to whole device in marine site, ocean and use procedure and can only swim in the water surface, be not suitable for the induction of demersal fishes.
A kind of artificial poly-fish protective device is disclosed in publication number CN103070097A, although this device structure is simple, easy to use, have certain limitation in use procedure, and the gathering effect of fish not that clearly the scope of application is less.
Summary of the invention
