The Rivers and Fisheries Trusts of Scotland (Rafts) have set out a programme of action at a local level, reports BBC News.
According to the BBC, they include ways of improving habitats for fish and working with farmers, water and power firms whose industries may affect the health of rivers.
Rafts believes the plans will help ensure that Scotland's fisheries remain the envy of those across the globe.
The charity said the proposals would help protect and improve stocks of different species of fish.
Rafts has 22 fishery trust members covering more than 90 per cent of the country, and is currently engaged in about 70 projects including habitat restoration, rare species reintroduction, dealing with pollution and woodland management.
