The presence and impact of nonindigenous (introduced) marine organisms in Kaneohe Bay, Oahu, Hawaiian Islands are evaluated using a combination of historical records and on-site surveys. Findings are compared with the results of similar studies conducted in Hawaii and the Pacific.
Observations and collections were made in November 1999 to January 2000 at 24 stations from variety of habitats and environments throughout the bay and from one site at Moku Manu Island outside the bay. A comprehensive literature review of published papers and books and unpublished reports was conducted to develop a listing of previous species reports, and the marine invertebrates, fish, mollusk and algae collections at Bishop Museum were queried for information regarding all organisms that had been collected from Kaneohe Bay. The assembled data were developed into a relational data base used to determine the 1999-2000 percent component of the total biota that was non indigenous or cryptogenic, the number of new reports for the bay versus the number of previous reports not found, and a chronology of first reports of introductions. Data are in .xls and .csv files with a complete included .pdf report.
