Abstract

A buoyancy system is for a fish pen. The fish pen has an enclosure for keeping fish confined in the fish pen, the enclosure being secured to an inner flexible buoyancy body floating on a water surface. The buoyancy system has an outer buoyancy body on the outside of the inner buoyancy body. The inner buoyancy body is attached to the outer buoyancy body with a mooring so that the outer buoyancy body and the inner buoyancy body move independently of each other relative to waves.

Abstract

An outlet basin for a fish pen is provided with at least one outlet hose extending from the outlet basin to a surface. The outlet basin includes a cylinder-shaped housing which is provided, at its upper portion, with a mounting collar arranged to be attached to a bottom portion of the fish pen, and which is provided, at its lower portion, with a through opening. The outlet basin further includes a cylinder-shaped outlet channel which, in a portion, is housed in the housing, the outlet channel is provided, at its upper portion, with a strainer covering the cross section of the outlet channel, an elongated annular space between the housing and the outlet channel, a slanted grating covering the entire annular space, the lowermost portion of the slanted grating being positioned just below the opening of the housing, a slanted bottom plate sealingly covering the entire annular space, and a lower through opening at the lowermost portion of the bottom plate.

Abstract

A buoyancy element is for constructing a modular buoyancy system for a circularly shaped net cage. The buoyancy element includes a cage side, an opposite straight long side, and coupling sides between the cage side and the straight long side. The cage side is curved, following the periphery of the net cage.
