UK: Study to assess hemp as fish food

Researchers in the UK are looking into hemp as a potential source of protein in aquafeed. However, salmon lovers hoping that this might add an extra mood-altering kick to their favorite fish are set for disappointment.

Rare Earth Global, growers of industrial hemp for a range of sustainable products, has received £50,000 in funding from the UK Seafood Innovation Fund (SIF) to explore how hemp seeds could be integrated into the diets of farmed salmon in Scotland.
