 struction, the purse seine used in waters >30 m 

 by both NMFS and OSU was assumed to fish to 

 about 24 m deep. 2 



Personnel of NMFS, fishing in waters >30 m, 

 collected seven juvenile wolf eels in 1980 (232 

 sets) between Copalis Head, Wash., and Til- 

 lamook Bay, Oreg. These fish ranged in length 

 from 430 to 506 mm SL. 



One of these juvenile wolf eels had been tagged 

 on 24 October 1978 off Doyle Island near Port 

 Hardy, British Columbia (Fig. 1), by personnel 

 of the Canadian Department of Fisheries and 

 Oceans (Bailey 3 ). The tag was applied inciden- 

 tally to a purse seine tagging operation for chum 



MIGRATION OF A JUVENILE WOLF EEL, 



ANARRHICHTHYS OCELLATUS, FROM 



PORT HARDY, BRITISH COLUMBIA, TO 



WILLAPA BAY, WASHINGTON 



Juvenile wolf eels, Anarrhichthys ocellatus, 

 were rarely reported off the Washington-Oregon 

 coast prior to 1979. One 87 mm juvenile was col- 

 lected by midwater trawl in 1962, 80 km off 

 Newport, Oreg. (Wakefield 1980 1 ). Another 

 juvenile of 468 mm standard length (SL) was 

 caught in 1969 (51 sets) by personnel of the 

 Northwest and Alaska Fisheries Center, Nation- 

 al Marine Fisheries Service (NMFS), while 

 purse seining for juvenile salmonids in shallow 

 marine waters (<30 m in depth) adjacent to the 

 mouth of the Columbia River. 



While purse seining for juvenile salmonids in 

 these same waters, no wolf eels were caught in 

 either 1978 (49 sets) or 1980 (67 sets) by NMFS, 

 but in 1979 (109 sets), 19 specimens between 467 

 and 531 mm SL were collected. Oregon State 

 University (OSU) personnel caught 113 juve- 

 niles during a 10-d purse seine cruise for juvenile 

 salmonids in 1979 (56 sets) between the Colum- 

 bia River and Coos Bay, Oreg., in waters >30 m. 

 These fish ranged in size from 281 to 610 mm SL 

 (Wakefield 1980). The purse seine used in waters 

 <30 m deep fished to a depth of about 6 m (veri-
