The structure of fish assemblages accounted for by different sampling methods (e.g., net types, visual surveys) can differ significantly, even among similar ones, in terms of species composition, functional groups (ecological and trophic guilds), and fish size distribution. Consequently, a cross-validation of fish sampling methodologies is necessary to ensure standardization and comparability of monitoring methods.
Biomonitoring and bioassessment of fish community structure in a marine protected area with environmental DNA metabarcoding: a pilot EDNAM project
The ongoing HMPA monitoring project monitors surf-zone fish community composition and species abundance with seine net and tag-and-release surveys. Given that structure of fish assemblages accounted for by different sampling methods (seine net and tag-and-release surveys) can differ significantly, Reel Science Co. aims to apply marine environmental DNA metabarcoding as an alternative, non-invasive sampling method, to get a near-comprehensive snapshot of fish species composition and community structure, and site occupancy rates in the HMPA, and illuminate the strengths and limitations of each sampling approach.
