If, like me, you're not a professional angler, have a job and other commitments, you often have to squeeze a few hours fishing in when and where you can.
When I can only spare a few hours I head for the local river. Fish roam around but fishing the same stretches you're bound to bump into the odd fish more than once, but I wonder how often it happens?
Some fish are specimens, with closely studied photos, some have distinctive marks and are easy to recognise. But would you recognise an average size, none distinctive fish next time you caught it? Probably not.
How many fish have you caught? Probably a lot less than you think...
