This report reviews available fish survey methods and the limitations and constraints presented by the lakes within the SSSI series, to design a standardised, practical, and representative method for fish survey which could be reasonably applied throughout the SSSI lakes to achieve comparable results.

This is part of our Good Practice Guidance for Fish, produced by Vaughan Lewis, Steve Coates and Kerry Sims.
