Description
Technical field
The invention belongs to aquatic products and fishery field, further relate to the related fieldss such as hydraulic and hydroelectric engineering, environmental science, specially
A kind of fish are temporarily feeding, swimming behavior is observed and tests structure with Burden-Swimming Ability of KM.
Background technique
Construction of hydropower plant, especially huge high-head power station construction, inevitably destroys original river
Connectivity blocks the channel of fish upstream or downstream, destroys habitat of fish.Fish pass structure slows down as river connectivity is restored
The important measures of dam blocking effect, pay close attention to by domestic and foreign scholars.Fish pass structure import is nearby and its interior flow field is recognized
To be the key that fish pass structure design and running.And fish swimming capacity and behavior as fish pass structure import and inside flow velocity,
Fluidised form design considerations is tested particularly important with the accuracy of observed result.
Currently, fish swimming capacity test carries out usually in laboratory, experimental rig is usually annular water tank, will be tested
It is strapped in small space with fish, drives water body in annular water tank to form different flow rate environments by propeller, by observing fish
Class walk time and swimming state variation in small space, establish fish swimming capacity index.Since wild fish is to environment
Factor variation is very sensitive, is detached from natural surroundings and is easy to cause fish dead, the fish for Burden-Swimming Ability of KM test are usually to support
It grows or the fish by raising and train for a long time, rather than wild fish.Studies have shown that the Burden-Swimming Ability of KM of fish under field conditions (factors) is wanted
It is better than fish swimming capacity in laboratory, the Burden-Swimming Ability of KM of wild fish is also better than fish swimming capacity after domestication relatively.Obviously,
The fish swimming capacity index system that the test of fish swimming capacity is set up is tested indoors to raise and train fish for a long time, not
It can truly reflect Burden-Swimming Ability of KM of the fish under natural endowment.
There is following some problem mostly in existing fish swimming capability measuring device and means:
1. experimental rig narrow space is usually only capable of one fish of receiving and is tested, fish movement is limited in scope, and is difficult to reflect fish
Class hides the behavior of high flow rate.
2. experimental rig is simply possible to use in fish individual Burden-Swimming Ability of KM testing experiment, it is impossible to be used in fish group Burden-Swimming Ability of KM and
Measuring behavior test.
3. fish swimming process can make corresponding adjustment, experimental enviroment flow velocity list according to water environment situation under natural surroundings
One, the case where being different from reservoir, lake and river there are change in flow, it can not accurately observe fish swimming behavior change and convection current
The Burden-Swimming Ability of KM index of the selection course of fast environment, foundation not can accurately reflect fish swimming capacity and swimming behavior.
4. experimental rig do not have fish temporarily support environment, only fish swimming capacity test environment so that test with fish with
It raises and train based on fish and cultivation fish.
Therefore, it is necessary to develop it is a kind of can be used to wild fish and temporarily support test structure with Burden-Swimming Ability of KM, it is natural accurately to establish
Wild fish Burden-Swimming Ability of KM index.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of fish temporarily to support, swimming behavior observation is surveyed with Burden-Swimming Ability of KM
