HABITAT FOR PROVIDING ECOSYSTEM ENVIRONMENT OF FISH

摘要

Habitat for providing an ecological environment for fishes is provided. Multistage fish shelter includes a plurality of shelves where fishes can spawn and hatch or hibernate. Each shelf provides different inhabitation environments in consideration to the inhabitation conditions to the preference to various kinds of fishes, and a muddy-stream blocking water gate blocking a muddy stream when water level of the inside of a body where multistage fish shelter is installed reaches a predetermined height. The present invention provides proper environments of inhabitation environments for structural particles of an underwater ecosystem and fishes for the structural particles of an underwater ecosystem and fishes which inhabit in an inhabitation environment damaged by artificial activities in a freshwater area or which are not sufficient, thereby providing an ecological environment for fishes to form an optimal inhabitation environment for structural particles of the underwater ecosystem by providing environments to stably spawn, hatch, flee for refuge from floods and natural enemies such as birds, and a resting place.
