Northern range extensions and habitat observations for blackeye goby Rhinogobiops nicholsii and kelp perch Brachyistius frenatus in southeastern Alaska
Csepp DJ and Wing BL. 2000. Northern range extensions and habitat observations for blackeye goby Rhinogobiops nicholsii and kelp perch Brachyistius frenatus in southeastern Alaska. Alaska Fishery Research Bulletin. 6(2):78-84
Blackeye goby Rhinogobiops nicholsii (Bean 1882) and kelp perch Brachyistius frenatus (Gill 1862) were caught or observed from April to September 1998 and 1999 with beach seines and a remotely operated vehicle at 20 locations near Sitka, Craig, and Klawock in southeastern Alaska. This is the first verified account of blackeye goby (Gobiidae) and kelp perch (Embiotocidae) in Alaska. We captured blackeye gobies as far north as lat 57°17'26"N, long 135°35'14"W, near Sitka, and kelp perch at lat 55°34'38"N, long 133°05'42"W, near Klawock; these may be the northern range limits for these species. Blackeye gobies were found in greater ranges of temperature (9.5° to 17.0°C) and salinity (13 to 27 on the Practical Salinity Scale) than kelp perch (10.0° to 13.2°C, salinity 22 to 28). Specimens of both species have been deposited and cataloged in the Auke Bay Laboratory fish collection.
