Copper alloys in aquaculture copper sheathed hulls. Many complicated factors influence the environmental performance of copper alloys in aquaculture operations. A technical description of antibiofouling mechanisms, fish health and welfare, fish losses due to escapes and predator attacks, and reduced life cycle environmental impacts is summarized in this reference. Copper–zinc brass alloys are currently (2011) being deployed in commercial-scale aquaculture operations in Asia, South America and the US (Hawaii). Extensive research, including demonstrations and trials, are currently being implemented on two other copper alloys: copper-nickel and copper-silicon. Each of these alloy types has an inherent ability to reduce biofouling, pen waste, disease, and the
Industrial rock sales and awards bands featured in this page, arranged by number of awards: The following list is composed by IFPI certificated albums only (no Soundscan): Industrial rock sales and awards This is a page containing all available sales and awards from industrial rock and industrial metal artists. This list is far from complete. Many countries were excluded from it because their Industry Associations lacked a searchable, online database. Belgium, Iceland and Mexico are some of them. Some European countries who do have it (Greece, Hungary and Spain) were excluded anyway, because their databases showed no relevant sales pertaining industrial rock and metal groups.
