I go back to "too little land, too many people" . I'm not sure, from a morality point of view, that dynamiting fish is worse than catch and release? One is to feed ones family, one is not. Now, if the fish are being stolen from another persons land, thats theft and is plain wrong. If its their pond though? In my head your land = your business.
Well think of it from a conservation point of view if you are feeding your family with everything from your lake you will eventualy run out of the bigger fish if you kill all the smaller fish my problem with explosive (and poison fishing) is it's indiscriminate in it's results. It's effective unquestionably but rappidly becomes too effective and does not allow the environment and stocks to replenish if over used.
Realy? couldn't find any legislation could you provide some
Various paching laws and a few fish and fisheries ones. Spear gun fishing is allowed but only just a man driven spear used while wading is definitely covered under a poaching law.
I think in the case ASM was referenceing the "damage" was as much, or more, to the reef itself as to the fish taken.
This as well, I would rather enjoy longer lasting fish stocks than a quicker result with no lasting reward (poor wording sorry). And if you kill the environment off the fish just wont come back.
