So catching 100 king fish, stressing them out out, then releasing is considered morally right. I'm not sure, I know C&R is considered a sport and sustainable but more and more evidence is coming to light that these stressed fish may not survive as much as we think. Personally I gave up throwing big barra a long time ago as got used to seeing crocs walk out onto the sand bank soon after throw back with a big barra in their jaws. Now I have no proof it is the one we threw back, just too many coincidences and I don't go out specifically to C&R as I don't believe in stressing an animal/fish purely for the purpose of enjoyment, I treat all fish caught with utmost respect, I even have a special rod for offshore work to release any unrequired fish down to the depths they were caught at as quickly as possible even though it may take time away from a hot bite.
I think Gazza you should care where your 1 fish for your meal comes from because in all probability 10 other undersized or undesirable fish possibly died in the process of catching that 1 fish.
Also go back a few posts and reread Disorderly's post and others about people catching their limit. There will always be a very small minority that are pure number crunchers but they are getting fewer and fewer.
Cheers
