A full-cycle self-adaptive fish passing system and method

Abstract

The present application belongs to the technical field of ecological fishery, and relates to a full-cycle self-adaptive fish passing system and method. The system comprises a detection module, a self-adaptive fish luring pool, a fish passing channel, and a V-shaped water channel flap. The detection module comprises an entrance detection unit arranged at a downstream entrance and an exit detection unit arranged at an upstream exit. The self-adaptive fish luring pool is arranged at the downstream entrance. The water inlet of the fish passing channel is in communication with the water outlet of the self-adaptive fish luring pool. The fish passing channel comprises a water channel body and a partition plate arranged in the water channel body. The partition plate is arranged along the length direction of the water channel body, and divides the water channel body into multiple parallel sub water channels. The V-shaped water channel flap is arranged on the side wall of the sub water channel. The V-shaped opening of the V-shaped water channel flap faces the upstream direction of the water flow. A water passing fence is arranged on the V-shaped water channel flap. The present application realizes the full-cycle self-adaptive passing of fish with different habits, greatly improves the fish passing efficiency and the level of biodiversity protection.
