The International Copper Association, (ICA), the leading organization for promoting the use of copper worldwide, announces the deployment of four copper-alloy cages by EcoSea S.A. in Puerto Montt, Chile. Each of the four circular cages measures 40 meters in diameter and is comprised of approximately 18 tons of copper mesh.

Chile has recently suffered fish losses due to virus attacks and bacteria. Copper alloy meshes stay naturally clean in a marine environment, preventing nets from clogging with organic matter and providing improved circulation and water flow. This improved water circulation leads to healthier fish and cleaner oceans. The growing global population requires additional protein sources, and fish farmed in 100 percent recyclable copper-alloy nets represent an environmentally friendly and economically feasible solution. In 2009, more than 12 percent of Chilean fish harvested were exported to the U.S. for a total of $737 million.

According to Rodrigo Sanchez, EcoSea’s general manager, “In the future, the strength and durability of copper alloy meshes will allow the development of new enclosure designs that can be deployed in deep offshore waters, reducing the stresses to inshore environments associated with current aquaculture enclosure designs and operational practices.” The cages are constructed from UR30™ mesh (65 percent copper, 35 percent zinc). The strength of copper alloys also prevents attacks from predators such as seals and sharks, preventing fish escape.

Copper is an essential micro-nutrient, helping achieve good health and development in all organisms. Due to its natural metallurgical and biological properties, copper alloys are a perfect material for both surface and submersible marine aquaculture enclosures for near- and off-shore sites. In the U.S., copper-alloy technology is used in the Northeast and Hawaii.

EcoSea Farming S.A. was formed via funding by CORFO/CONICYT (Chilean technological development agencies) and through efforts by Codelco, the International Copper Association, the University of Conception, the Catholic University of Valparaiso, Foundation Chile and Sitecna.
The International Copper Association increases awareness and usage of copper by communicating the unique attributes that make this sustainable element an essential contributor to the formation of life, to advances in science and technology, and to a higher standard of living throughout the world. The ICA's 37 members represent a majority of the world's refined copper output and are among the largest copper producers, fabricators, and wire and cable companies.
