Salmon industry to gain from £2.9 million cleaner-fish projects

A consortium of academic, government and aquaculture industry bodies have announced projects worth £2.9 million to increase the use of cleaner-fish in the Scottish salmon industry. Initiated by the Scottish Aquaculture Innovation Centre (SAIC), the research will focus on lumpsuckers, a species of fish that is known to eat sea lice, a natural parasite which feed on both wild and farmed...

Fish farming industry could benefit from keeping fish in semi-closed or closed systems for part of their life cycle

New research  conducted by scientists at Uni Research in Bergen, Norway has found that the  fish farming industry could benefit from keeping fish in semi-closed or closed systems for part of their life cycle.  Problems with lice and losses can be heavily reduced by placing farmed fish in closed systems until the fish reach a weight of one kilo.  "The open sea...

It has a considerable impact on the environment, which is largely due to three factors: the accumulation of food waste and faecal matter; the toxicity caused by the chemicals employed to clean the cages; and the drugs that are used. The impact of such farms on the coastal environment is...

This is important information because millions of farmed salmon escape into the wild –...
