Open net pens

These pens are situated in coastal waters and allow fish to grow in an open ocean environment. Species such as salmon, trout, and tilapia are farmed using this method as it applies to both saltwater species as well as freshwater species. Nets pens are anchored to the bottom and allows for water to freely flow through them. Pens are typically constructed from welded steel pipes, heavy duty rubber hinges, and mesh/net screens.
