It is always interesting to hear about work being done in the field of fish pass design and fish passage, particularly high quality research investigating the effectiveness of solutions to improve fish passage. A team at the University of Durham have recently conducted some work quantifying the effectiveness of various solutions to improve the passage of brown trout at in-stream structures.
The results mirror those from the Fishtek study last year into the effectiveness of LCBs at improving fish passage at gauging weirs, where LCBs were found to be an efficient solution for permitting the upstream passage of both coarse fish and brown trout. The results are summarised in a poster presentation, available at the link below:
