Fish such as Atlantic salmon, sea trout and lamprey have been recommended for inclusion on a list of priority Scottish marine species.
Scottish Natural Heritage (SNH) is identifying wildlife and habitats that require conservation action.
SNH expects the list to be put out for public consultation before being considered for adoption by the Scottish government.
It contains 36 habitats and 46 species drawn from an original list of 324 species and 151 habitat types.
