The monkey fish of Australia live in holes in the coral reefs. One way if procuring these otherwise difficult-to-catch fish is to force them to use up their oxygen. The method is straightforward, though less than sporting.
At low tide, a thick layer of a native grass is placed over the fish’s hole and then secured with a large rock. Upon returning at the next low tide twelve hours later, the fisherman should find the monkey fish floating at the top of its borrow, asphyxiated.
