Submersible Net Pens

Underwater fish farm with circular net pens extending below the ocean surface, anchored by cables and weights.

Keep fish protected below the surface

Innovasea’s SeaProtean Pen is a fully submersible aquaculture solution that allows fish farms to utilize anywhere in the water column. Grow, feed, and protect fish by ensuring ideal conditions regardless of what’s happening at the surface.

Simple, precise movement for improved fish health

The SeaProtean net pen features the industry’s best buoyancy control system for smooth, steady movements when it matters most. Using a unique three-stage buoyancy chamber, the pen allows a single operator to effectively move fish to ideal conditions.

Seamless underwater operations

Maximize feeding days

Innovasea’s fully connected underwater network allows fish farms to conduct all critical farm operations beneath the surface.

Maximize feeding days and achieve consistent, reliable growth throughout the year.

Ensure consistency regardless of surface conditions 

By submerging both the pens and grid, farms gain peace of mind knowing their fish are protected regardless of storms or strong currents.

Easy operation and upkeep

A streamlined design keeps pens cleaner and allows a single operator to raise and lower the structure efficiently, without needing a crew or advanced training.

Meanwhile, the pen’s integrated mortality recovery system effectively traps dead fish, reducing the need for divers.

Unmatched fish protection

Safely move fish below the surface and out of harm’s way. With the ability to move the pen anywhere in the water column, farm operators can:

  • Avoid oxygen-depleting algal blooms and parasites.
  • Find optimal currents to keep fish active and healthy.
  • Prevent theft, vandalism, and escapes.
  • Avoid storms and rough surface conditions.
  • Locate ideal water temperatures to optimize growth and avoid thermal stress.

A long history of innovation

Our  SeaProtean Pen is the result of more than 25 years of innovation and evolution.

We’ve gone from the AquaSpar, a proven near-shore pen that’s still producing salmon, to the futuristic-looking Aquapod, a geodesic dome in use across the globe.

Now, with our fully submersible solution we are once again setting the standard for offshore fish farms.
