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 metal collaborations with and remixes from industrial metal musicians. When industrial metal climbed the charts of the late 1990s, its sudden popularity was met with negative reactions from the early innovators of industrial music. Peter Christopherson told "The Wire" that he no longer felt any kinship with the industrial scene: "this is not me, this is not what I'm about". Lustmord, a prominent early industrial musician, declared that "Ministry just doesn't interest [him]" and "[he has] no time for all this rock and roll shit they're doing now." Skinny Puppy frontman Nivek Ogre dismissed Nine Inch Nails as "cock rock" but
