Field Studies of Corrosion Behaviour of Copper Alloys in Natural Seawater

Field Studies of Corrosion Behaviour of Copper Alloys in Natural Seawater

July 4, 2013

Eight copper alloys were tested in a one-year field deployment in the North Atlantic Ocean. The corrosion behaviour was characterized by weight loss, optical and electronic microscopy analyses. The biofouling performance was quantified in terms of the biomass accumulation. The testing program included specimens in tensioned and untensioned configurations, as well as a set for seasonal deployments. The seasonal corrosion[...]

Copper Alloy Mesh Pens Easily Meet Stringent Water Quality Standards for Copper in British Columbia

Copper Alloy Mesh Pens Easily Meet Stringent Water Quality Standards for Copper in British Columbia

June 4, 2013

Researchers monitoring copper concentrations from two copper-alloy mesh (CAM) pens installed in the Fortune Channel in British Columbia (BC), found full compliance with strict BC environmental regulations. The International Copper Association worked with Mainstream Canada to install the copper alloy mesh pens in the Fortune Channel near Tofino, B.C. in November of 2012. An aquatic chemistry team[...]

Van Diemen Aquaculture Study

August 27, 2012

There is a great deal of complexity associated with the analysis of performance of Atlantic salmon in brass nets at Van Diemen Aquaculture (VDA) and it is challenging to succinctly portray the advantages of brass nets based on VDA performance over the last six years – having said that VDA would no longer be a commercially viable Atlantic salmon farm[...]

Effect of Netting Materials on Fouling and Parasite Egg Loading on Offshore Net Pens in Hawaii

Effect of Netting Materials on Fouling and Parasite Egg Loading on Offshore Net Pens in Hawaii

July 17, 2012

Parasitic skin flukes, primarily Capsalid Monogeneans, Benedenia sp. and Neobenedenia sp. are a scourge to the marine aquaculture industry worldwide. These parasites infect a wide range of hosts in tropical and temperate waters, causing immediate irritation and stress to the animal and, if levels are left unchecked, can lead to bacterial infections and eventual death. The life cycle and physiology[...]
