...debris that it twice caught fire. Masses of dead alewives washed ashore in Lake Michigan, fouling beaches. Tangles of Cladophora, a smelly freshwater seaweed, clogged other beaches. Commercial fisheries, which had long flourished on the lakes, perhaps a bit too aggressively, began closing for lack of good fish and fear of DDT and mercury contamination...
Large game fish are making a comeback. Virtually wiped out by overfishing, pollution and the eellike sea lamprey (an ocean predator that apparently first migrated from the Hudson River into the lakes after man had opened the way with the Erie Canal, the native lake trout is again being pulled from the lakes by sports fishermen, who now can also catch coho and chinook salmon from the Pacific Ocean. Still, despite the fact that the waters are cleaner and the lamprey has been contained by a concerted attack on its breeding ground, the game fish population can be sustained only...
Toxic substances in the lakes are now the environmentalists' major concern The levels of such chemicals as mirex (an insecticide), PCBs and mercury are still too high to allow the resumption of commercial fishing, and Canada publishes a guide that warns sports fishermen which fish are unsafe to eat. Says Leila Botts, chairman of the Great Lakes Basin Commission...
...every scientist agrees. Says John Ryther, another Woods Hole biologist: "I don't believe drilling will cause mass mortalities of fish." The Government maintains that the leases cover no spawning grounds on Georges Bank, and that the prevailing currents could easily sweep an oil slick to sea. Secretary of the Interior Cecil Andrus notes that of 292 million bbl. of oil produced last year from off-shore U.S. wells, only two spills exceeded 50 bbl., the largest losing only 135 bbl. Besides, the oil revenues that could be realized even from a small reserve at Georges Bank are hard...
...deepest; one fisherman's tale has it that a ship's crew was able to play baseball on a shoal after a storm. The Gulf Stream and the Labrador Current converge at the site and circulate a hearty brew of nutrients on which plankton thrive and proliferate. Fish in turn feed on the plankton and spawn seasonally in the shoals, coming from as far north as the Arctic, as far south as the Carolina coast...
