Biodegradable active substances with high efficacy against fouling organisms
Active substances for aquaculture is derived from the much larger industry of ship hull paints. When a biocide is to be used for net protection in fish farms it is important to consider not only environmental risks but also it's food near application. The solution must be safe for fish welfare as well as not accumulative in fish tissues. Modern antifouling technology has proven that it is possible to have fully functional biofouling protection systems without copper.
AquaNet Protect - an active coating
Mechanical wear and tear
AquaNet Protect is developed as an active coating. This means that it in addition to delay entry of biofouling also withstands light in-situ cleaning. Therefore, the need for in-situ cleaning operations can be reduced while the net remains protected even after the first cleaning.
Steen-Hansen has tested all active ingredients applicable and approved for use in the sea. In cooperation with Janssen PMP is Econea® identified as the best candidate. High efficacy, long protection time and that it is biodegradable - makes Econea® especially suited for aquaculture. Together with increased resistance to mechanical wear and tear and its own algae protection, copper free antifouling from Steen-Hansen make good choices for future fish farming.
AquaNet Protect is a copper free product range from Steen-Hansen based on Econea®.
