Figure 6 
Proportion of fish found in each habitat type by size class tested with Pearson’s chi-square 
(% 2 ) test for Opakapaka (Pristipomoid.es filamentosus), Kalekale (P. sieboldii), Onaga (Etelis 
coruscans), and Ehu ( E . carbunculus) within the preferred depths of each species in the main 
Hawaiian Islands. A baited stereo-video camera system (BotCam) was used to collect data from 
May 2007 to June 2009. The 4 habitat classifications used in our study were hard substrate 
with high slope (hard-high), hard substrate with low slope (hard-low), soft substrate with 
high slope (soft-high), and soft substrate with low slope (soft-low). <i=number of BotCam 
deployments; n=number of fish measured. References for size at maturity: Kikkawa, 1984 (Opa- 
kapaka); DeMartini and Lau, 1999 (Kalekale); Everson et al., 1989 (Onaga); Everson, 1986
