People have relied on the world’s oceans, seas and rivers as sources for fish for thousands of years. As the global population continues to grow, so does the demand for protein, especially meat and fish.

Aquaculture is the farming of aquatic organisms, such as fish, shellfish and plants – in water off land or in the open ocean. The health and growth of fish are actively managed to improve production and profitability. The $43 billion marine aquaculture industry produces 19 million tons of fish and shellfish annually and supplies almost half the world’s demand for fish, according to a United Nations study, titled the State of World Fisheries in Aquaculture 2012.

The use of copper alloy mesh in aquaculture helps promote a clean energy economy. From decreased CO2 emissions to decreased fish mortality, copper alloys promote “green” living and help fish farmers realize greater cost savings. Copper and its alloys are 100 percent recyclable, unlike other net materials. Copper-alloy nets are durable, so they last longer.

Environmentally friendly fish nets offer significant advantages. Their natural ability to stay clean prevents them from clogging with organic matter, improving water circulation and leading to healthier fish, higher yields, lower costs and reduced environmental impacts. The strength of copper alloys aids in fish development and keeps predators away. Copper-alloy mesh is successfully used in Australia, Chile, Japan, Canada, Scotland and other countries worldwide.

As we look to feed the world in the future, the use of copper alloy mesh in aquaculture exemplifies the philosophy of “People, Planet and Profit.” Its unique model gives fish farmers worldwide the ability to safely produce high yields of fish while protecting the environment.

Copper Netting Impact: Improved Fish Harvest

Aquaculture is the fastest growing animal-food producing sector worldwide. Copper alloy netting improves fish production, leading to healthier fish, higher yields, and lower costs. In addition, copper netting:

  • Resists storm damage and lasts longer than traditional netting.
  • Reduces predator attacks and fish escapes.
  • Stays naturally clean, reduces drag and maintains cage volume.
  • Decreases impact of pathogens and parasites, as monitored by farmers.
  • Supports sustainable fish farming and is 100% recyclable.
  • Minimizes maintenance cost and efforts.
