High-density polyethylene (HDPE) cages are widely used, because of the versatility of the materials used
Global aquaculture production has been steadily growing in recent decades, increasingly contributing fish and other edible aquatic organisms of commercial importance entering national, regional and international markets.
The growing demand for such products has stimulated the development and expansion of aquaculture production systems both on land and in all waterbodies, covering technologies ranging from the production of seed material to ongrowing structures and other farming support facilities.
High-density polyethylene (HDPE) net pens are widely used, because of the versatility of the materials used, the relative simplicity in the performance of the various farming operations, and the comparatively limited investment capital required.
Technological improvements of HDPE cages are evolving with the availability of new materials and the various equipment items needed to service all farming operations.
Benefits polyethylene cage fish farming:
Low cost relative to fish farming in earthen ponds or CCTV system;
Management easier and less costly;
Ease of observation and study of fish nutrition and health;
Easy and economical treatment against parasites and diseases;
Compared to earthen ponds and CCTV system requires less investmen;
In the case of environmental pollutants and suspended solids, which can be problematic for the cage, the cage can be moved.
