| Research Abstract |
This project aimed to develop a habitat evaluation system that can deal with spatiotemporal dynamics of fish habitat preference. Two hybrid models of a genetic Takagi-sugeno fuzzy model and a fuzzy neural networks model were developed and evaluated for its accuracy and applicability in ecology. Four major achievements in this project are as follows :(1) laboratory experiment on the diurnal changes of habitat preference of Japanese medaka,(2) new method for optimization of a genetic Takagi-sugeno fuzzy model,(3) evaluation of effects of data quality on a habitat preference model,(4) application of fuzzy habitat preference model to topmouth gudgeon.
