undervannsfôring

Undervannsfôring, also known as underwater feeding or subsea feeding, is a technique used primarily in aquaculture, particularly in salmon farming. It involves delivering feed to fish pens located offshore or in areas where traditional surface feeding methods are impractical or inefficient. The feed is transported through a pipeline from a shore-based facility or a feeding barge to the submerged cages.

This method offers several advantages. It can reduce feed loss due to currents and surface disturbances, leading to improved feed conversion ratios and reduced environmental impact. By delivering feed below the surface, it minimizes the attraction of unwanted species such as seabirds, which can also reduce disease transmission. Furthermore, underwater feeding can help to distribute feed more evenly within the water column, potentially improving fish growth and welfare.

The technology typically involves specialized feeding systems that can precisely control the amount and placement of feed. Sensors may be used to monitor fish behavior and feeding activity, allowing for automated adjustments to optimize the feeding process. Challenges associated with undervannsfôring include the engineering complexity of the feeding infrastructure, the potential for pipeline blockages, and the need for robust monitoring systems to ensure efficient and effective delivery. Despite these challenges, it is considered a valuable tool for sustainable and efficient aquaculture operations in many regions.
