...effrontery. In Arizona a mutant Chinese grass carp, the sterile triploid amur, has been released into the ponds and water hazards of golf courses to keep the water free of entangling weeds lest golf balls be lost or the scenery spoiled. An African fish, the tilapia, cruises irrigation canals devouring any growth that might impede the water flow, but it endangers the Colorado River's sport fish. Coast to coast, European starlings darken the skies. A century ago, the first few were released in New York City by a reader of Shakespeare bent on sharing with the New World every...
...oyster on its bed of ice could have been pampered like an orchid in Quilcene Bay on the Hood Canal in Washington, or in Tomales Bay near Marshall, Calif. The two fish that Jesus served to the multitude in the New Testament parable may well have been mild-flavored tilapia. The species is native to the Sea of Galilee, but it is now farmed in increasing numbers in Caldwell, Idaho, where a large potato-processing company feeds it the leftovers...
...Nomenclature is central to fish marketing," says Bob Rubin, a partner in the Chicago Fish House, a wholesale distributor. "The name has to sound good. You could have a perfect fish that tastes like candy, but if it's called a ratfish, it won't sell." Speaking of the tilapia, a prolific and delicately flavored fish, he says, "It doesn't sound like something you'd want to eat." Bill Demmond is not so sure. "Fishermen couldn't give away amberjack," he says. "Now it sells for $1 a pound wholesale. We can't keep enough seafood. If they catch...
...McLarney have created a prototype agricultural "ark," a self-sufficient food-producing complex involving greenhouses, fish ponds, solar heaters and a windmill. The odd layout is clustered around three greenhouse-covered ponds built on an incline. The lowest pond contains a variety of edible fish, mostly the tasty tropical tilapia (somewhat like the sunfish). Pumped by the windmill, the water from this pond is passed through a solar heater, then circulated through a bed of crushed, bacteria-laden shells in the topmost pond. The bacteria not only detoxify the fish wastes but convert the ammonia in them to nitrites...
Full Diet. Then the algae-enriched water is fed into the middle pond, where the microscopic plants provide feed for tiny crustaceans called daphnids, or water fleas. Finally, water containing fleas and algae flows back into the bottom tank, where it provides a full diet for the tilapia. Nothing is wasted: in the warm greenhouse space above the ponds, the new alchemists grow vegetables even in the dead of the New England winter. The plants are fertilized by the nutrient-laden fish water. To protect their harvests against bugs, the scientists have brought insect-eating frogs, spiders and chameleons instead...
