i personally wouldnt shoot a shark, wrasse, sunfish, smooth hound, dogfish, rockling or scad, but anything that is legal and sizeable is fair game as long as i can (or another family member) can and will eat it. on a side note, i personally think new spearos are mis guided as to the minimum size of fish they can shoot, mainly because of the size of the fish sold in supermarkets. i know most of these are farmed but ive often walked past and thaught surely that bass is below the minimum size, and that i would never shoot something "that small".
