0 Not pertinent - No information, or no + Present, or yes ? Unknown, or questionable Abundance trend (surveys) Historical trends Routine monitoring Impacts assessed Feedback into management

2 b. Fishery, legal Sweden Effort, graph over time
Catch, graph over time 0 Not pertinent - No information, or no + Present, or yes ? Unknown, or questionable Mortality, graph over time Historical trends: Routine monitoring Impact assessed Feedback into management

3 c. Fishery, recreational
Sweden Effort, graph over time Catch, graph over time 0 Not pertinent - No information, or no + Present, or yes ? Unknown, or questionable Mortality, graph over time Historical trends Routine monitoring Impact assessed Feedback into management

4 d. Fishery, illegal, unreported
Sweden Effort, graph over time For illegal fisheries, this graph is probably irrelevant. Leave it out, but do not change the outline of the sheet as a whole. Catch, graph over time 0 Not pertinent - No information, or no + Present, or yes ? Unknown, or questionable Mortality, graph over time Historical trends Routine monitoring Impact assessed Feedback into management

5 e. Upriver migration, habitats
