For assessment purposes, the Hawaiian bottomfish stocks
are considered a single, archipelago-wide, multi-species
complex. Scientific analysis of bottomfish catch data for
the Hawaii Archipelago indicate that, at current levels,
the amount of fishing effort on bottomfish in the main
Hawaiian Islands (MHI) will not be sustainable in the long
term. In other words, if no action is taken to reduce the
fishing effort and mortality of MHI bottomfish,, declines
in the populations of seven commonly caught deepwater
bottomfish species—opakapaka, onaga, kalekale, hapuupuu,
ehu, lehi and gindai (the “Deep 7”) will continue. The
amount of fishing effort occurring in the Northwestern
Hawaiian Islands, on the other hand, has been determined
to be operating at sustainable levels.
