Abstract

PROBLEM TO BE SOLVED: To provide a fish reef capable of artificially raising a tidal current in the vicinity of the bottom of the sea, inducing the upwelling of nutritious materials, plankton, etc., in the bottom of the sea and improving the effect of a fish gathering and of a fry growing rate. SOLUTION: This fish reef having a characteristic of an upwelling flow is obtained e.g. by taking a tidal current into a bank having a taking in port for the tidal current and constructed as a double structure, for changing the direction of the current to upward and discharging from an upper part thereof, and next, installing a joining wall to make a bank having a cross shape or a three arrows shape for taking in the tidal current from all directions. Further, a cave of the bank produces an effect as a fish reef, and also, the fish reef is preferably made from a steel or a concrete.

It attracts the upwelling of plankton, etc., and enhances the fish collection effect and the fry breeding rate. In order to attract upwelling currents, we have invented a fish reef that enables upwelling by taking in tidal currents from all directions so that it can catch and rise regardless of which direction the tidal current is flowing. First of all, the tidal current was taken into a bank constructed in a double structure with a tidal current intake port, and the flow was changed upward so that it was discharged from above. Next, in order to allow the tidal currents to be taken in from all directions, various combinations were possible, such as combining levees with cross-shaped or three-arrow joint walls and combining them. The levee cavities and the central cavities that can be formed by combining them produce the effect as a fish reef. According to the present invention, in order to artificially induce an upwelling current, a tidal current can be taken in from all directions, and a fish reef featuring upwelling utilizing the tidal current is manufactured from steel or concrete.
