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.
In recent decades, the aquaculture industry has also intensified its production output per unit area of space or volume, mainly to compensate, among other things, for the growing competition for land and water surfaces for other uses. The expansion of fish farming in the sea, also referred to as “mariculture”, has happened as a result of several supporting factors. These include the acquisition of reproduction and ongrowing technologies for species of interest, and the development of physical structures to contain the cultured organisms. Modern marine cages, whether floating or submersible, represent one such development. These have evolved significantly from basic and rudimental systems to sophisticated and carefully engineered structures.
Many cage designs and models have been developed and are commercially available. Among these, high-density polyethylene (HDPE) cages 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.
HDPE cages are mainly used for shallow sea aquaculture, with good performance and the ability to cope with high wind and wave climate.This is a aquaculture project in Singapore. The customer chooses DN250mm, PN16 HDPE pipe and single and double brackets as the main pipe and frame, 110mm black pipe as the handrail, inside fishing net, outer net, and cover net as the bird proof net, including pipe fittings, bends, tees and other accessories, for tilapia. All the HDPE pipes have been added with black carbon and UV protection additives to extend the service life in the harsh using conditions.
We not only provide customers with pipe & fittings with other accessories, we also provide customers with butt fusion welding machines, our perfect supply chain system for customers not only save a lot of time, but also ensure that our pipes and pipe fittings can be a good match.
