SeaProtean Pen

SeaProtean Pen

Affordable, easy-to-operate submersible net pen features the industry’s best buoyancy control system for smooth, steady vertical movement to alleviate fish stress.

Simple, Precise Movement

The SeaProtean Pen is an affordable submersible fish pen designed for sites that experience occasional weather events, such as strong storms or surface currents. Made from high-density polyethylene, it features a unique three-stage buoyancy chamber for smooth, steady movement when raising and lowering. This prevents fish stocks from experiencing barotrauma and gives operators the precision needed to find the ideal thermocline to maximize fish health.

Improves operations

The SeaProtean pen is designed so a single operator can raise or lower it simply by opening a valve, which improves farm efficiency. The pen also reduces operational costs with its unique, integrated mortality recovery system, an optional feature that reduces the need for divers.  

The pen can also incorporate Innovasea’s underwater feeding solution, which allows operators to feed fish stocks while the pen is submerged, reducing missed feed days, boosting growth rates and improving feed conversion ratios.   

The SeaProtean Pen features a unique, three-chambered buoyancy system.

Tough and versatile

Safe and secure with rugged netting, SeaProtean is ideal for: 

  • Farms looking to diminish surface presence due to aesthetic concerns.  
  • Areas susceptible to algae blooms or other surface-based threats.  
  • Locations that could be subject to theft, vandalism or sabotage.
