The article below, by Jon McAllister, highlights the hazards of retaining fish for long periods and promotes nights shots of fish to help avoid this:
Whilst we of course have a vested interest in the welfare of our fish, fish welfare should be something that all anglers aspire too. Only by looking after the fish will they still be their the next time we want to fish, hopefully having put on a few pounds in the meantime!!
As a consequence we promoted the taking of night shots through our facebook page and the response from anglers has been fantastic. A massive “thank you” to all of you that have sent in night shots and please keep sending them in.
