How do you rescue fish? Electric Fishing is a good place to start of course. www.bbc.co.uk/news/magazine-17212119 Have a look at the BBC magazine you may see yourself here who knows?
"We started having to do a few rescues in November and December last year, which is almost unheard of. We are expecting to do a lot more over the next few months and over the summer."
Only approved operators can use the equipment, which is described as very "fish-friendly". There are few mortalities, says David Rogers, professor of freshwater biology at the University of Derby.
"The fish recover quite quickly. It's like us going in for an operation and being anaesthetised and coming round afterwards, you feel a bit groggy."
