Effects of ecological restoration for habitat of the Cobitis sinensis at Jie-Mei spring channels of Miaoli

Abstract

In these recent years, the developing pattern of the farmland's waterway is not only seeking a better way for irrigating, people are paying much more attention to the ecological construction, all the living animal in the water and surrounding plants, they could have their living environment restored due to the ecological construction. Miaoli city irrigation association's first period of the ecological construction, they broaden the waterway, try to have a deeper water living environment, also set up some stones to reduce the water flow, this construction was successfully creating a habitation environment of food, breeding and avoid attacking for Cobitis, a genus of ray-finned fish. After researched in May and July of 2009, compared to the waterway without ecological construction, we found out the Cobitis love to live in the environment that we created, because it has slower water flow and deeper water, the result showed us that the ecological waterway is a great achievement, beneficial result between the waterway and farmland. After the research, laboratory analyzing of water quality and soil, we could see Cobitis is partial to the environment with this construction, avoid the quick water flow living area.
