were recaptured. Recaptures were reported for up 

 to 6 years following the year of tagging (Table 2). 

 Of the 149 lingcod with known tagging and recap- 

 ture locations, 75 were recaptured <8.1 km from the 

 tagging location and judged to be nonmigratory, 

 whereas the remaining 74 were judged to be migra- 

 tory, having been recaptured at distances >8.1 km 

 from the tagging location (Table 3). Of the 74 that 

 migrated, 61 were recaptured 8.1-50 km from the 

 tagging location and 13 were recaptured farther 

 than 50 km from the tagging location. The extent 

 of migration depended on the location of the tag- 



ging site. Only one of 15 recaptured lingcod tagged 

 in San Juan Channel migrated, whereas 70 of 117 

 (60%) tagged at Middle Bank and Hein Bank 

 migrated (Table 3). 



The predominant pattern of movement was west 

 and south through the Strait of Juan de Fuca; 65 

 of the 74 migratory lingcod were recaptured south 

 and west of the tagging site, but only 9 were re- 

 covered north and east of the tagging site (Table 

 3). The null hypothesis that lingcod were as likely 

 to go south/west as north/east was rejected (x^ = 

 42.4 with 1 df; P < 0.001). Five recaptures from the 

 Pacific Ocean were reported; the one farthest from 

 the tagging location was caught off Newport, OR, 

 a migration of 564 km.^ The longest migration to 

 the north/east was to Porlier Pass, BC, Canada, 

 about 75 km from the tagging site. The greatest 

 number of recaptures (34) was from Constance 

 Bank, located in Canadian waters about 18 km west 

 of Middle Bank. Most of the Constance Bank recap- 

 tures were made by Canadian trawlers. About one 

 third of the total reported recaptures were taken 

 in Canadian waters and two thirds in U.S. waters, 



^This unusual recovery location was verified by follow-up corre- 

 spondence. The fish was recaptured 6.5 yr after tagging by a small 

 coastal trawler that usually fished 3-8 mi off Newport's south jetty.
