Closing the Sluices. Over the years, the pollution has taken an ecological as well as esthetic toll. The Rhine salmon, once a river staple, has long since disappeared from the murky waters, as has the sturgeon. The hardy varieties of fish that remain-bream, carp, perch and pike-cannot be sold because the river's high phenol content makes them smell and taste foul. Last week even the survivors were imperiled. Millions of dead fish floated to the surface, victims of the worst case of pollution in the river's history...

Why had the Germans failed to sound the alarm sooner? The North Rhine-Westphalian state government explained that a warning was issued to all German waterworks along the river.

Once sharks and other predators that normally swim singly or in small groups can be concentrated into selected areas, it may become profitable for commercial fishermen to "harvest" them, thereby tapping a rich new source of protein. Similar tactics might be used to satisfy less adventuresome tastes in seafood. "If we can make this little damselfish twist and turn around in the open sea," says Myrberg, "maybe some day we can make a snapper jump into...
