The eel manual, published by the environment agency (environment agency, 2011a), provides best practice guidance on protecting and enhancing eel populations, one of which is providing eel.
Eel Pass Casterbridge Fisheries Ltd Easy to install, maintain, and monitor for safety, these passes provide a seamless and reliable route for numerous elvers. the design and material choices ensure the longevity of the pass, contributing to the sustained success of elver migration in the face of contemporary challenges. This project reviewed how different designs of eel passes in england are working. the aim was to identify any problems with installed passes and consider how to improve the design and. Using controlled experiments and custom‐built eel passes with contrasting crest shapes (curved vs. sloped) and flow directions (ascending vs. descending), we quantified the effect of crest conditions on the attempt success, passage efficiency and speed of ascending juvenile eel. Huntons are able to offer the full design, build and installation package including eel tiles or brushes, fixed or opening walkways over the top, stoplogs or penstocks to allow maintenance, pumped solutions and the integration of underwater lights or cameras as is required.

Rip rap scour protection to extend minimum 1000m dn s of eel pass, at depth of minimum 450mm. ramped laterally at eel pass toe to marry with tile inverts. s3 consistency class Ɣ reinforcement: all steel reinforcement shall be deformed type 2 and shall be cut and bent to bs4466 or bs4449. Ɣ0lqlpxpfryhuwruhlqirufhphqw&min = 60mm. A structure that enables eels to bypass an obstacle in a channel such as a lock, weir or control gate. eel passes are displayed in aims om as a point in the centre of the structure. aims om. Fishtek uses innovative approaches to improving eel and elver passage and we are able to provide eel pass design for virtually any site, regardless of the size or location of the barrier. passes can be gravity or pump fed, with a wide range of designs and substrate types available. Employing an experimental setup that simulated gravity fed upstream eel passes, this study demonstrated that novel v profile passes, which incorporate two lateral slopes (15°), performed better than laterally flat passes over the flow rates tested (0.2–0.6 l s−1).
