The utility model provides an imitative nature fishway of narrow dark type that can adapt to multiple target population, includes side wall, side slope, pond room, main dividing pier, crowning dividing pier, low or middle dividing pier, bottom strip mound, cobble or piece stone. Through set up different types of water facilities of hindering inside the fishway to making to form in height, width and front and back between the various facilities and interlocking, thereby reach the interior cranky characteristic of rivers of imitative nature fishway on the one hand, on the other hand realizes flow field " vertically subregion, horizontal layering ", and fingerling crowd's migration needs are crossed to the sectionalized satisfied different swimming abilities of layering. The utility model provides a receive field condition restriction and higher to environment protection requirement, need richen under the condition of the imitative nature fishway of the narrow dark type of section construction section at fish resources, various migratory fish swimming capacity variance is great, the difficult problem hardly compromise provides new method and new thinking for imitative nature fishway construction.
