- Cusk-eels and brotulas of British Columbia have been poorly studied, and until now, there were published records of only Spectrunculus grandis and Brosmophycis marginata from our waters. However, a single specimen of S. crassus has been identified from among the few S. grandis from British Columbia held at the Royal British Columbia Museum. Furthermore, increased sampling effort from deep-water surveys, shrimp surveys, and the commercial fishery revealed 5 additional cusk-eel species and 1 brotula offshore of British Columbia. Two specimens of Chilara taylori were collected from the southern Strait of Georgia at depths of 78 to 109 m. A single specimen of Acanthonus armatus was taken from near Triangle Island at 1778 m and is the 1st record for the eastern North Pacific Ocean. One specimen of Cherublemma emmelas was found at 1097 m in Kyuquot Canyon, west of Vancouver Island; 4 specimens of Bassozetus zenkevitchi were collected from depths of 1909 to 2125 m west of Vancouver and Graham islands; and a specimen of Cataetyx rubrirostris from 2000 m and a Porogadus promelas from 1967 m were taken in Queen Charlotte Sound, east of the Tuzo Wilson Seamounts. Because of increased sampling effort from 1999 to 2007, we now understand the number of cusk-eels and brotulas in British Columbia to be 9 species.
