BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block for an open channel in which living things coexist.

[0002]

2. Description of the Related Art In the past, the concept of directly extracting only available elements from nature in economic growth and using them for direct judgment was dominant. Today, some of the natural environment has been destroyed and the country is facing ecological destruction.

[0003] In order to cope with this ecological environment and seek the coexistence of living things and to enrich life, activities rooted in the local natural environment have become active in various places. As part of this, fireflies, dragonflies and mizusumashi have been established in small rivers The creation of a communal zone of waterside insects, such as stag beetles, and small fish, such as medaka, has begun to shout.

The inventor has been involved in the propagation of fireflies and the like for many years as a volunteer, but according to his experience, fireflies live in the waterside grassland, their larvae eat Kawaninina conch, and Kawanina conch lives in the mud. Like dragonflies eating flies and mosquitoes, dragonfly larvae goats eat small fish and daphnia and other small fish and worms eat diatoms, and all these waterside insects and small fish are unicellular. We focused on using diatoms as the starting point of the food chain.

[0005] Therefore, the inventor has laid or stacked pebbles and gravel on the bottom and wall surfaces of the open channel of irrigation and industrial water, to form a portion where water stagnates, and this portion promotes the propagation of phytoplankton, The present invention has been completed in which zooplankton that feeds on the zooplankton, insects, small fish, and the like are attracted and stayed here, and the vegetation grows so that living organisms coexist and the flora and fauna are diversified.
