I haven't seen the it yet.
To be honest, before I joined I hadn't given much thought to a lot of the points raised within the club on conservation/sustainability/dispatching etc... having been brought up in France until my early teens and then on to Spain, they certainly didn't seem to have the same respect as far as I recall. It's great that the club raises the profile of these issues.
I use to enjoy spearfishing as a teenager and always though of it as giving the fish a sporting chance... well in fact a GREAT sporting chance as I never managed to catch many. Now, if I ever did this again I would certainly dispatch any catch asap and as for gaffing and returning, shocking!!! I can't see any excuse for that.
I do wonder were the line is drawn on dispatching though? For instance, why dispatch a bass but not mackerel? I am yet to understand the difference.
