In situ observation data from the grouper roi (Cephalopholis argus) removal project in West Hawaii from 2010-2011 (NCEI Accession 0082197)
In situ observations of the introduced predatory grouper roi (Cephalopholis argus) were taken within the coral reef ecosystem of Puako, northwest side of the Island of Hawaii in 2010-2011. Baseline surveys before roi removal were made in November 2010 and March 2011. After roi removal, a final survey was made in June 2011. A total of 47 transects were surveyed at control, reference, and treatment sites. Observations were made by experienced marine biologists using SCUBA at a depth range of 10-20 m. Tow board and standard visual belt transects were employed.

Supplemental Information | Hawaii Coral Reef Initiative Grant Number: NA09NOS4260242 NODC Accession 0002172 (Data related to feeding biology of the introduced fish roi (cephalopholis argus), and its impact on Hawaiian reef fishes and fisheries between January 2004 and January 2005) contains complementary information. |
Purpose | To test the ecological effects of the introduced predatory grouper roi on a native reef-fish assemblage in Puako, west Hawaii. Objectives: a. Quantify effort required to reduce roi populations. b. Determine immigration patterns of roi into a cleared area. c. Compare fish census and survey methods with catch data to determine fish population abundance. d. Detect any change in the native reef-fish assemblage through a predator removal experiment. e. Collaborate with the fishing community to strengthen partnerships. |
