Cephalopholis argus fish census and assemblage data from the West Hawaii Roi Removal Project 2010-2012 (NCEI Accession 0099263)

This on-going research project, which began in September 2010, evaluates the impact of roi removal by collaborating with local fishers to remove >90% of the roi from a patch reefs in Puako, West Hawaii. In situ observations of the introduced predatory grouper roi (Cephalopholis argus) were taken semi-annually within the coral reef ecosystem of Puako, northwest side of the Island of Hawaii October 2010 - July 2012.

Visual fish transects were made at a depth range of 10-20 m. Tow board and standard visual belt transects were employed at control, reference, and treatment sites. Data include biometrics (length and weight) and biomass of roi, as well as an assemblage of other fish and feed guilds.
