1. The proportion of the rod catch accounted for by catch and release has generally increased since 1994, when such information was first recorded. In 2020, 93% of the annual rod catch, and 99% of the spring rod catch, were released. Salmon fishery statistics: 2020 - gov.scot (www.gov.scot)
2. In 2015, a new set of rules came into force in Norway to regulate the collective responsibility for recapturing farmed fish that have escaped and ended up in rivers.

OURO is financed by the industry and involvement is compulsory for farmers.
