Background
The water conservancy and hydropower engineering brings considerable influence on the ecological environment, particularly on the blocking influence on a fish migration channel while giving full play to the benefits of flood control, power generation, shipping and the like; the fish passing facility is used as a fish protection measure for relieving the barrier effect of the dam for more than 300 years internationally, and the main types of the fish passing facility comprise a fishway, a fish elevator, a lifting lock chamber, a fish transporting system and the like; the fish passage effect of the fish passage is optimal, the application range is wide, and the fish passage accounts for about 90% in the established fish passage facilities in China.
The fishway monitoring is always an important link for fishway operation, and as the history of developing fishway construction research in China is short, fish passing objects are greatly different from foreign objects, and foreign monitoring data has a limited reference value for fishway design in China, the fishway monitoring method is particularly important for monitoring data of fishway operation effect in China.
At present, the domestic and foreign monitoring schemes are basically that an observation room is directly arranged on the side wall of a fishway to observe migration fish schools in the fishway, only observation and counting can be carried out, fishes cannot be collected and sorted, and the types of the fishes cannot be identified and measured; the currently used video and infrared monitoring can not realize the work of identifying and measuring the fish species and the like.
According to the prior art, when the fish species and specification are identified, the method generally comprises two methods: firstly, a plurality of pool rooms need to be intercepted by using a net, and fishes in the pool rooms are fished out by using a fishing gear and a fishing net; closing the exit gate of the fishway, emptying part of the pond-type water, taking out the fish, sorting and counting; the above two methods have the following disadvantages: (1) only the fishes in a plurality of instantaneous pond chambers can be sorted and analyzed, the sorting quantity is small, the sorting efficiency is low, and if the fishes need to be completely sorted and counted, the fishes need to be fished for many times; (2) in the sorting process, the net is easy to damage the fishes, and the fishes are easy to die due to dehydration operation; (3) the work of sorting, identifying and measuring after fish collection needs to lift the fish out of the fishway, and the lifting process is time-consuming and labor-consuming.
How to make the fish collection and identification of the fishway more efficient, reduce the injury and death rate of the fish and better realize the multi-functionalization of the fishway observation room is a technical problem; the invention can improve the fishway monitoring efficiency, better protect the fishes and provide important reference for other engineering fishway designs.
