The article surveys technologies intended to reduce environmental impacts in fish farming. For sea lice, it names Harbor’s electrical barrier, Stingray Marine Solutions’ machine-vision-guided lasers, Fishency Innovation’s SmartFunnel for imaging and lice monitoring, Plany’s shelter system for cleaner fish, and Blue Lice’s attract-and-capture trap. These company capabilities are presented by the source and not independently evaluated.

For feed, the page describes C-Feed’s land-based copepod production for fish larvae and Zooca’s ingredients from Calanus finmarchicus. It also points to software and systems for feeding management, including Spillfree and CageEye, and Gas 2 Feed’s fermentation-based feed ingredient.

Alternative farm designs include EVN’s autonomous offshore fish-farming vessel, with current deflectors for its pens; Bluegreen Technologies’ Marine Donut closed or semi-closed salmon system; FishGLOBE’s enclosed mobile units drawing water from below the sea-lice belt; and FiiZK’s closed pens and waiting pens. The article frames offshore and closed systems as ways to manage waste, escapes, parasites and local environmental effects. Benefits and specifications are claims from the source page.
