the English tagged in the San Francisco region, 11 moved an average 

 distance of 54 miles north, 17 stayed within 12 miles of tagging, and one 

 moved 25 miles northwest. Dover sole tagged off Eureka showed 16 fish 

 moving about 30 miles north, with 39 fish staying within 10 miles of 

 tagging. Six petrale sole moved 35 miles north from the point of tagging 

 in the Eureka region, and 19 stayed within 10 miles of release. 



The general pattern of migration indicates that the majority of the 

 soles are nonmigrants. Only a small interchange of English sole between 

 the Eureka and San Francisco region occurs with a slight northward 

 migratory trend in both regions for dover and petrale sole. 



The study of trawler boat logs was continued by the Bureau of Marine 

 Fisheries to follow changing trends in species caught, fishing localities, 

 depths, and fishery progress from year to year. The logs indicate that 

 many boats are now fishing in waters of depths of 300 fathoms and 

 over with good success. The general trend of the fishing effort is toward 

 the offshore deeper water.
