PROTECTION FOR FARMS FROM HARMFUL ALGAL BLOOMS

PROTECTION FOR FARMS

Protection for farms from harmful algal blooms, with Garware Skirt X12 anti bloom. Innovative technology applied to anti bloom fabric has proven 100% blocking efficacy of Heterosigma Akashiwo and Alexandrium Catenella, along with other microalgae from 1 to 10 microns.

We know that harmful algal blooms cause high fish mortality in both Norway, Canada and Chile. To prevent this problem, Garware Technical Fibres – as an international provider of aquaculture innovations for profitable and sustainable growth – develops and markets the Skirt X12 AB anti bloom in the global market. “Our Skirt X12 AB protect aquaculture centres from microalgae blooms. Our particular anti bloom fabric – tested in the Chilean laboratory of the University of Concepción, Faculty of Natural and Oceonographic Sciences – prevents microalgae from 1 to 10 microns from passing through, with a blocking efficiency of 100% of Heterosigma Akashiwo and also of 100 % of Alexandrium Catenella ”, specifies Gopakumar Menon, Americas General Manager, who emphasises that in Canada this solution is already operating successfully in farming centres.

Thus, Garware’s Skirt X12 anti bloom is capable of blocking harmful algae cells, protecting fish; provides a long service life, has good wear resistance compared to other HDPE, polyester and nylon fabrics. It is also easy to install and clean and is friendly to the environment

Harmful algal blooms (FANs)

Around 4,000 species of marine phytoplankton have been described worldwide, around 300 of them “flourish” regularly with adverse effects and 80 have the property of producing toxins. Harmful effects occur when these algae synthesize toxic secondary metabolites that cause harmful effects to fish and humans.

Recently, the algal bloom in the Comau fjord in southern Chile – Los Lagos region, Palena Province – puts salmon companies in the region on alert, precisely because of a harmful algal bloom of the microalgae Heterosigma akashiwo. Events like these also produce economic losses, losses in harvest estimates and the consequent work of moving the surviving fish. www.garwarefibres.com
