Marine biologists research finds over-hunting shark is detrimental to the food chain

A study by marine biologists at The University of Western Australia has found that fishing by Indonesian shark hunters may have resulted in changes to fish communities on a major reef off Western Australia’s North-West coast. The study, published in the journal Marine Ecology Progress Series, concluded that sharks may influence the number, kind and size of fishes on coral reefs and that they should be protected from overfishing.
