I'm not sure why it is even an issue.
All you need is, the rule must say that no dead fish are weighed and must be released alive. If the fish doesn't make it then tough, you are out of the running, the fish is disqualified.
I've been advocating this for years and got a lot of resistance from the don't cares. To them a fish is something you throw in a bucket and weigh so you can get something. A bit of a mind change is required. The time when our natural resources existed in abundance is gone forever, and if the little bit left is not taken care of then it may be lost also.
Imo, if a person can afford the boat, tackle and especially the fuel (4 5 c) to take part in such a competition then surely the required equipment to treat his fish with a bit of respect is in order.
Weigh no dead fish !
Illegal gill netting is supposed to be taken care of by the authorities. The problem with these gill netters is they have also - same as the 'authorities' no sense of responsibility (typical) - the nets are put out and never recovered, resulting in dead fish in these nets. Sorry to say, but it falls in perfectly with so many wrongs in this FANIE up little coutry of ours as the authorities just turns a blind eye. If you however does same you will make TV news headlines, ok, so a bit of discrimination there as well.
It will in the end - as so many things before - be the few caring FANIE that has to take control to save the buggered up issue - and probably get blamed for the situation also.
