Fish pass manual

Fish passes can be designed using empirical methods and guidance outlined in the Fish Pass Manual from the Institute of Fisheries Management, but we have frequently found that there is a need for more detailed analysis. 3 General requirements for fish passes Optimal position for a fish pass Fish pass entrance and attraction flow Fish pass exit and exit conditions Discharge and current conditions in fish pass Lengths, slopes, resting pools Design of the bottom Operating times Maintenance. IFM-Guide-to-Stocking-Fish; IFM Fishery Maintenance Information; Managing-Fisheries-in-Prolonged-Dry-Weather; Fisheries and Nature Guidance; IFM Biosecurity Guide. We also hold the national Fish Pass Manual. This is the former EA Guide. The manual can be downloaded here.

Technical types such as Larinier, Denil, and pool-weir traverse passes often use series of metal, plastic, or wooden baffles attached to the bottom/sides of a constructed channel to create very specific flow conditions to allow their target species to pass.
