From: What is the impact of kelp forest density and/or area on fisheries?
Category | Quality of evidence |
---|---|
I | Evidence obtained from quantitative, random and/or replicated studies. This include quantitative data obtained by estimates of abundance (biomass and/or percentage cover for seaweeds and abundance for fishes), along randomly chosen and appropriately replicated transects, sampling points and/or quadrats. |
II | Evidence obtained from quantitative not properly designed studies (failing randomization, replication and control when applicable). |
III | Evidence obtained from qualitative field evidence, descriptive studies or reports of expert committees. |
IV | Evidence inadequate owing to problems of methodology e.g. sample size, length or comprehensiveness of monitoring or conflicts of scientific evidence. |
