Datagov Opendata Platform

This dataset mainly includes the survey of the basins, rivers, sampling points, dates, species, methods of use, and quantities of fish. The dataset is provided by the River Situation Survey Database Management System of the Water Resources Agency's Water Resources Planning and Experimental Institute, integrating the river situation data completed by the Water Resources Agency over the years. It serves as a unified management and inquiry website for river situation survey data. It is hoped to be used as reference data for river water resources management, ecological environment maintenance, and environmental improvement planning for river region structures. The key content of this dataset lies in the species, locations, and time of fish, allowing users to further analyze the spatiotemporal distribution of species. According to the operational points of the river situation survey, the survey should be carried out for at least one year, with a minimum of once per quarter, and the survey frequency should try to avoid using adjacent months as data for two seasons. The survey time should grasp the spawning period, migration period, and activity period of each fish species.
