A double pipe cultivation system which enables the reduction of falling the mussels cultivated with the effect of vertical and horizontal forces that would occur due to wind, wave and tides that can be received in all directions in mussel farms established in sea and lake areas, and the losses that can occur due to similar reasons.

A system (100) and method for attaching an aquatic basket (102) to a longline in an aquaculture farming environment. The system includes the basket (102), a longline engagement means (104, 105), and a locking bar (106) configured for slidable engagement with one or both of the engagement means and basket (102).

A pen system is for farming aquatic organisms. The pen system has an outer surrounding rigid structure and an internal, closed enclosure. The outer surrounding rigid structure forms an upper portion and a lower portion. The pen system further has: an internal surrounding connecting element, the closed enclosure being attached to the connecting element; and a heave-compensation system having a plurality of fluid-filled cylinders, each fluid-filled cylinder being hingedly attached, in a first end portion, to the connecting element, and being hingedly attached, in a second end portion, to the inside of the rigid structure.

A controllable and stable sinking/floating system for cage aquaculture is illustrated, which has a net cage and the sinking/floating units. The net cage comprises a frame and a net body installed on the frame. The sinking/floating units are installed on the frame, each of the sinking/floating units comprises a water storage chamber and a liquid flow controller, the water storage chamber has an inlet and an outlet, and the liquid flow controller controls water to flow out via the outlet from the water storage chamber or to flow into the water storage chamber via the inlet. When the water flows out via the outlet from the water storage chamber, the sinking/floating unit floats; and when the water flows into the water storage chamber via the inlet, the sinking/floating unit sinks.

An upweller array configured to be disposed in a body of water and that has one or more upweller systems. The one or more upweller systems include a buoy configured to float on the surface of the body of water, a tether coupled to the buoy and a hydrofoil rotor coupled to the tether. The hydrofoil rotor is configured to be disposed in the body of water based on a length of the tether.
