Although I agree with the above, it always seems a double-standard exists 
in many MPA's where collecting tropical fish is banned but recreational 
line fishing is not. As a diver I enjoy seeing large fish not just small 
tropicals. Sometimes political and special interest influences can outweigh 
the overall environmental benefits.
