Eel passage manual
1. To critically review published and unpublished literature on eel and elver passes, taking into account the issues of hydraulics, exit, entrance and approach, installation, robustness, maintenance and location. 2. To critically review the published and unpublished literature on the swimming speed of eel and elver and the factors affecting it. www.doorway.ru Size: 1MB. levels of water on each side, under either manual or automatic control. There are of course situations where these structures are located away from tidal influence, and they are used to isolate the area to be drained from high river levels in the channel to which they drain. The issues for eel passage are similar to those in tidal water. This manual sets out design criteria for upstream passage facilities at obstructions for eels and elvers, based upon assessments of the migratory behaviour and ecology of Anguilla spp. It is intended for use by fisheries managers with responsibility for or an interest in the management of stocks of eels and elvers. It is largely based upon.
