Interest in submersible or more rugged “offshore” (open ocean, high energy) pens has been increasing for the past several years because of the many benefits they bring to operator and the expansion potential they bring to the industry. However, they also can come with operational challenges like the risk of barotrauma in certain species due to cumbersome ascent/descent systems or the need to incorporate new feeding strategies when the pens are submersed. Innovasea’s designs incorporate features and capabilities to address many of these challenges.
