Abstract
An apparatus for generating a current to guide fish includes a propeller; a device to rotate the propeller; and a frame to mount the propeller and the device to rotate the propeller. Fish may be guided from an intake area to a fish bypass by generating a current leading away from the intake area. The apparatus may also be used to guide fish through low velocity areas in river situations.
Claims20
A method of guiding fish through a body of water, comprising the steps of:
- providing a plurality of louvers in an area in the body of water;
- creating a stream of water in the body of water;
- and
- directing the stream of water across the plurality of louvers in the body of water by pushing the stream of water from a location upstream of the plurality of louvers so as to create turbulence in the area of the plurality of louvers so as to cause fish in the body of water to avoid the area.
An apparatus for guiding fish through a body of water, comprising:
- a plurality of louvers in an area in the body of water;
- and
- means upstream of the plurality of louvers for creating a stream of water in the body of water, wherein the stream is directed across the plurality of louvers in the body of water so as to create turbulence in the area of the plurality of louvers so as to cause fish in the body of water to avoid the area.
An apparatus for guiding fish away from an obstacle in a moving body of water that is flowing in a first direction, comprising:
- a frame mounted upstream of the obstacle;
- means for creating a stream of water and projecting the stream of water into the moving body of water at an angle with respect to the first direction in which the moving body of water is flowing so that the projected stream passes across the obstacle, wherein the creating means is mounted on the frame.
A method of guiding fish away from an obstacle in a moving body of water that is flowing in a first direction, comprising:
- creating a stream of water;
- and
- projecting the stream of water into the moving body of water at an angle with respect to the first direction in which the moving body of water is flowing so that the projected stream passes across the obstacle so as to guide the fish away from the obstacle along a predetermined path defined by the projected stream of water.
A method of operating an upstream fishway, comprising the steps of:
- arranging a pair of sets of louver bars at an entrance to the fishway passage and diverging therefrom;
- and
- inducing a current at an upstream side of each of the sets of louver bars so as to create turbulence at an upstream side of each of the sets of louver bars.
