There are very strict International fishing laws for net fishing: The size of the holes in the net, the size of the net, how far from the shore it can be used, in what depth in the seas, what kinds of fish can be caught in what season, prohibitions on certain types of fish during breeding seasons, etc. etc. Are these rules followed by these expat fishermen who have very limited education? I see them selling ALL KINDS AND SIZES of fish as if they threw a net in an acquarium. If no one checks on them, very soon they will deplete the fish fauna of this wonderful country and its coastline.
