Transcription of Aquaculture operations in oating HDPE cages
{{id}} {{{paragraph}}}
Cage Aquaculture has grown rapidly in recent decades, and there has been a move towards the development and use of more intensive cage-farming systems to access and expand into untapped open-water areas, particularly in marine offshore waters. Fish cages vary in design, size and materials used, as they have been designed for employment in diverse environments, ranging from relatively protected to highly exposed and dynamic sites, either as floating or fully submerged structures. This technical manual focuses on high-density polyethylene (HDPE) cages as they are widely used in modern industrial marine Aquaculture in many parts of the world. It provides the reader with highly practical and technical information on the design and components of a typical HDPE cage, and on how a cage collar is assembled and the net pen installed. Along with the structure of the cage, comprehensive information on the grid mooring system and installation is provided.
