paperback. Zustand: Good. Moderate wear, binding sound, rear cover has slight damage from sticker removal, internally clean. The New Alchemy Back Yard Fish Farm Book, a nontechnical primer on small-scale aquaculture, offers information on the cultiva-tion of fish as a low-cost, high-quality protein food. The book contains sections on fish cage culture; cage design and construction; the selection, feeding and harvesting of fish; and a directory of available resources. Fish cage culture systems are analogous to home vegetable garden systems in their ability to produce healthful, abundant food for home consumption at low cost and minimal space requirements. Cage-grown fish, like their ocean counterparts, are a superb source of low-fat and low-cholesterol food. They are also less vulnerable to industrial and chemical pollutants such as PCBs and heavy metals than are wild ocean and freshwater fish. They are inexpensive, nutritious and fairly tasty! Enough is now known to enable fish and other aquatic crops to be grown cheaply for home use, using methods that are ecologically gentle and energy efficient. This book is about one method, cage culture of fish, which is potentially usable by every person who has access to a natural or artificial pond. If the New Alchemy Institute has its way, the day may come when the yellow bullhead, channel catfish, trout and carp are as common to the American back-yard as the tomato and cabbage!
