Fish meat is more prone to carrying certain "other types" of toxins. Majority of fish are still caught from the sea/water bodies (not fish farms), which means the various, erm, industrial discharges into water bodies may enter the bodies of fishes (depending on relative locations of fishing and factories, of course). So you can be pretty sure they weren't reared on traditional agricultural steroids to boost flavour of meet or health of fish.

Having a teacher-ful weekend... parents brought me out to novena square for lunch, and saw ms. melissa lim shopping in $1.99 shop (where i got my new pencilcase). Then saw edward nathan marketing at cold storage there. Today when i was walking down mt. sinai to school, mr. kamal stopped to give me a lift. Hrrmmm.
