Proposal of Optimum Fishway System Based on Field Investigations
Proceedings of the International Symposium on Fishways '90
The purpose of this paper is to see what an optimum fishway system is, mainly, with water utilization facilities. To liquidate the dilemma between development and preservation, it is necessary to proceed with the design and construction of fishways, on one hand, and to seek, on the other hand, to secure fishery resources preserve the species by determining how far and how fast river development should go. This is only possible by developing optimum fishway systems according to field demonstrative studies. This paper describes the modelling of maintainable optimum fishway systems, mainly from the technical approach, and shows their predictability.
