The particular snake, which lives in Singapore, feeds on soft-bellied crabs by tearing them apart one bite at a time. According to New Scientist, within four generations of taking larger fish, individual adults averaged 1.05 grams compared with 6.47 grams if the tiddlers were taken. Conover believes that current policies of taking larger fish and throwing the smaller ones back is giving rise to a selection pressure for slower-growing fish. "That's bad news for fishery managers who throw back small fish to allow them to grow to maturity in the hope that it will keep fish populations at sustainable levels," the magazine says.
