Fishpond was the code name given to an extension to the British H2S airborne radar system fitted to Royal Air Force (RAF) Avro Lancaster and Handley Page Halifax heavy bombers during World War II. It was designed to give early warning of German night fighters approaching in the hemisphere below the carrying aircraft out to a range of 30 miles (48.2 km).

Fish cage farming is practiced all over the world. By keeping fish in cages, entire communities can share a body of water, while each farmer can tend to their own individual fish farm. Fish cage farming is attractive to many individuals because a large crop can be raised, tended and harvested in a small area. Since the fish are in a concentrated area, problems can be quickly recognized and addressed.




Harvesting

One of the benefits of fish cage farming is the ease of harvesting the fish. Fish may be removed with a hand-held net and processed or transported as they are removed. If the cage is large, nets may be used to move the fish toward one corner, where they may be more easily hand netted.
