| Research Abstract |
A fish population dynamics model was developed in this study. The model is specialized to the objective of contributing preliminary deliberation when re-networking projects by setting of fish-ways will be assumed for conservation of a fish population in fragmented habitats. The model is able to take account of fish individuals' movement, uses the parameter expresses the success rate in each passage blockage in addition to population ecological parameters such as a reproductive rate or a carrying capacity, and predicts reproductive processes of the local fish population. Operations of the model under various scenarios permit comparing results quantitatively.
