Hawaiian deepwater bottomfish fishery target species referred to as the “deep 7” 
as recorded by BotCam in Hawaiian waters from depths between 100 m and 300 
m. (A) Etelis coruscans (longtailed red snapper or onaga), (B) Etelis carbunculus 
(red snapper or ehu), (C) Pristipomoides zonatus (Brigham’s snapper or gindai), 
(D) Pristipomoides sieboldii (von Siebold’s snapper or kalekale), (E) Pristipomoides 
filamentosus (pink snapper or opakapaka), (F) Aphareus rutilans (ironjaw snapper 
or lehi), and (G) Epinephelus quernus (Hawaiian grouper or hapu'upu'u). 
129 counted at the time of MaxNo (43%), and to mea- 
sure 78 P. filamentosus out of the 134 counted (58%). 
The ability to measure a fish was constrained by the 
angle of orientation of the fish to the camera, distance 
from the camera, amount of overlap with other fish, 
and video clarity. Etelis coruscans fork lengths ranged 
between 432 and 833 mm (mean ± standard deviation 
[SD] = 605.7 ±26.8 mm, Fig. 6A), and P. filamentosus 
fork lengths ranged between 344 and 660 mm (mean 
±SD = 518.0 ±10.9 mm, Fig. 6B).
