iv  Science Manual – Using Video Images for Fisheries Monitoring   
Acknowledgements 
The Project owes a big “thank you” to Jim Gregory, Emma Washburn and Peter 
Clabburn of Environment Agency Wales (EAW). The latter pair spent a year each on 
assignment, devising ingenious ways to combine lighting and camera arrays, deploying 
equipment and talking already overworked colleagues into helping out and analysing 
results. Thanks also goes to the Fisheries Assessment Team of EAW for the loan of 
their equipment and experience and to three of the aforementioned overworked 
colleagues, Adrian Fewings, Paul Elsmere and Mick Donkin of Environment Agency. 
The project also received the help and support of Pembrokeshire Anglers Association, 
Salmonsoft Inc., Radiant Inc., and Perceptive Solutions Ltd. We have tried to distil 
from all the above sources as much of the collective expertise as possible and 
reproduce it in this manual.
