Within the preferred depths of a species, either BRFA location, habitat type, or the interaction of these 2 factors had an effect on the relative abundance of 3 of the 4 species studied (Table 1).
BRFA location, habitat type, and the interaction of these 2 factors were significant for Ehu.
In our evaluation of mean lengths, BRFA location, protection, and habitat type were all important factors, and the interactions between them were sometimes significant (Table 2).
BRFA location, habitat type, and the interaction of BRFA location and protection were significant for Kalekale.
The Niihau BRFA has been closed to fishing since 1998.
To address this problem, the WPRFMC turned to the DAR, which created 19 bottomfish restricted fishing areas (BRFAs) and prohibited bottomfishing in them (Div.
Habitat was classified at a resolution of 200x200 m for areas in and around BRFAs. Polygons for high and low slopes and hard and soft substrates were generated with the Raster calculator in ArcGIS 9.1.
