PISCO: OSU: Subtidal: Community Surveys: Fish Survey

This metadata record documents the fish surveys for PISCO subtidal community surveys. Fish sampling consists of recording the number and size of all non-cryptic fishes on transects (each "transect" includes both a 2m x 2m x 30m "bottom" transect, "mid-water" transect and "canopy" transect at each site). Subtidal community structure surveys are conducted annually at all sites during the summer or early fall, and quantify substrate type and relief, benthic cover, abundance of major groups of macroalgae and invertebrates, and abundance and size of fishes. Spatial allocation of sampling is designed to measure year-to-year site-wide variability in community structure and the spatial scales at which such variation occurs. A site is defined as a fixed stretch of coastline, occupying approximately 500m. Each site is divided into 2 halves (areas), which comprise random factor stratified sampling over the entire site.
