Embodiment Construction

[0038]The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the present invention will be further described in detail through and specific implementation.

[0039] From June 2009 to March 2012, the Chinese Sturgeon Research Institute conducted surveys and statistics on all fish found in the ship locks during the maintenance of the Three Gorges Ship Lock and the Gezhouba Ship Lock. Fish resource surveys were carried out in the waters between the dams.

[0040] 11 species of fish were collected during the survey of the 3 lock chambers of the ship lock on the south line of the Three Gorges, namely: bream, meal, yellow catfish, shellfish meal, crucian carp, squid, grass carp, squid bream, snout, silver squid and Purple thin loach, a total of 823 tails. Among the above 11 species of fish, 4 species are di...

Abstract

The invention discloses a fish-gathering and luring system and a fish-gathering and fish-lure method of a fish-passing ship lock, comprising: a discharge horizontal corridor located in the downstream approach channel; an inlet end in the upstream approach channel, and an outlet end in the downstream approach channel; Water replenishment corridor system; the entrance end is in the upstream approach channel, and the exit end is in the lock room of the ship lock. On the ship locks of existing barrage projects and new barrage projects on navigable rivers, the fish-collecting and luring system of this fish-passing ship lock can gather downstream migrating fish in the ship lock.

Description

technical field [0001] The invention relates to the fields of water conservancy engineering and environmental protection engineering, more specifically, it is a fish-collecting and luring system for a fish-passing ship lock, and the invention also relates to a fish-collecting and luring system for a fish-passing ship lock using the fish-collecting and luring system Fish method, it is to solve the technical problem that migratory fish can trace back to the ship lock and gather. Background technique [0002] Building dams on natural rivers blocks the migration passage of fish in the natural rivers. The remedial measures taken at home and abroad are mainly three types: one is to build fish passing facilities, mainly including fishways, fish locks, fish lifts, and fish collection boats; the other is to build artificial simulated spawning grounds in the river; The third is to carry out proliferation and release. [0003] Existing fish remedial measures all have certain effects,...
