Abstract
Aquaculture apparatus includes an elongate tube of flexible translucent plastic material which extends longitudinally along level ground. The tube is inflated and air supported. At least the lower section of the tube defines a water course. The tube is closed at both ends to form a water enclosure. A number of such tubes are arranged in side-by-side relation and are covered by a plastic sheet cover layer. The cover provides an air gap to insulate the inner tubes and restrict heat loss. The tubes are used to form at least some of the modules of an aquaculture system for rearing fish and/or for effluent, waste or water treatment.

65. Aquaculture apparatus comprising
at least one tube of flexible translucent material, the tube extending longitudinally along a tube site and having a lower section defining a water course, the tube being of a material which is supported with gas inflation on level ground while avoiding the necessity for external retaining structure, and a cover extending externally over the tube, the cover being air supported and being spaced, at least partially, from the tube to provide an insulating space between the tube and the cover for insulating at least a substantial part of the tube.
