Pearl shell yield graph, 1890-1941

Pearl shell yield graph, 1890-1941. The yield per boat stands in an inverse relationship to the number of diving boats engaged in the pearling industry at Thursday Island, strongly suggesting that the resource was under stress from overharvesting, and that the best means of maximising profit would have been to limit the harvest.
