Dataset: Fish community surveys at artificial reefs in Kāneʻohe Bay, Oʻahu conducted in 2022 and 2023 as part of a reef halo dynamics study

Fish community surveys were conducted monthly at the same time as nutrient sampling and vegetation transects. Surveys were conducted by the same observer each time who would sit ~3m away from the reef to minimize disturbance, and record all fish seen within 1m of the reef for three minutes. After that time, the observer would move to the reef and attempt for another two minutes to record any fish that may not have been initially visible. This was repeated at each of the three artificial reefs.  Surveys were conducted with mask and snorkel.
