Systems and methods for the cultivation of aquatic animals

An aquaculture system, comprising:

• a pen having a first compartment, a second compartment, and a channel disposed therebetween, the pen configured to at least temporarily store aquatic animals during development in the first compartment and the second compartment, the pen configured to be disposed in a body of water such that water is allowed to flow therethrough, the pen defining a longitudinal axis;
• a first buoyancy tank coupled to a first side of the pen, the first buoyancy tank configured to at least temporarily contain a volume of fluid;
• a second buoyancy tank coupled to a second side of the pen opposite the first side, the second buoyancy tank configured to at least temporarily contain a volume of fluid;
• and
• a control system in fluid communication with the first buoyancy tank and the second buoyancy tank, the control system configured to adjust a volume of fluid in at least one of the first buoyancy tank or the second buoyancy tank to adjust at least one of an amount of the pen submerged below a surface of the body of water or an orientation of the pen relative to the longitudinal axis, the pen configured to rotate 180 degrees about the longitudinal axis between a first orientation and a second orientation when the control system adjusts the orientation of the pen.

• a first buoyancy tank configured to at least temporarily contain a volume of fluid and coupled to a first side of the pen;
• a second buoyancy tank configured to at least temporarily contain a volume of fluid and coupled to a second side of the pen opposite the first side;
• a third buoyancy tank configured to at least temporarily contain a volume of fluid and coupled to the first side of the pen in a stacked arrangement with the first buoyancy tank relative to the pen;
• a fourth buoyancy tank configured to at least temporarily contain a volume of fluid and coupled to the second side of the pen in a stacked arrangement with the second buoyancy tank relative to the pen;
• and
• a control system in fluid communication with each of the buoyancy tanks, the control system configured to:
• in response to a first input, adjust a volume of fluid in at least one of the buoyancy tanks to adjust an amount of the pen submerged below a surface of the body of water, and
• in response to a second input, adjust a volume of fluid in each of the first buoyancy tank, the second buoyancy tank, the third buoyancy tank, and the fourth buoyancy tank in a predetermined sequence to rotate the pen 180 degrees about the longitudinal axis between a first orientation and a second orientation.
