throughout the northeastern Pacific east of long. 

 155°W. 



The distribution of coho salmon in areas from 

 southeast Alaska (Chatham District) southward to 

 Rivers and Smith inlets (Figs. 98-100) was generally 

 east and south of the distribution of stocks from more 

 northern areas. 



The returns to areas near Vancouver Island and 

 Puget Sound were, with few exceptions, from nearby 

 tagging areas, and the distribution of stocks was 

 shown to be not as widespread as other coastal stocks 

 (Fig. 101). 



Washington coast to California. — Coho salmon 

 tag returns to the coastal areas of Washington, 

 Oregon, and California are illustrated in Figure 101. 

 Fish returning to coastal Washington streams showed 

 the widest ocean distribution of the three States; the 

 most distant returns were from off southeastern 

 Alaska and from the northeastern Pacific Ocean near 

 long. 143°W, lat. 47°N. Most returns were from tag- 

 ging off Vancouver Island. Columbia River returns of 

 tagged coho salmon were from releases off the river 

 itself and from near Vancouver Island. Oregon and 

 California coastal returns with two exceptions came 

 from tagging locations off Washington and Vancouver 

 Island. One Oregon return was tagged due west of the 

 northern part of the State about 670 km offshore. The 

 single tagged coho salmon recovered in California was 

 tagged in the northeastern Pacific near long. 133°W 

 and lat. 45°N. 



High-Seas Recoveries in Years Tagged 



The only high-seas recoveries of tagged coho salmon 

 in the year tagged were those in the Japanese high- 

 seas fishing area south of the Aleutian Islands and 

 west of long. 180°. These, of course, would be matur- 

 ing fish. Recoveries of tagged coho salmon in the 

 northwest Pacific Ocean (areas 27, 29-30) were, with 

 one exception, fish tagged within the recovery area 

 (Fig. 102). One coho salmon was tagged in the adja- 

 cent area to the east. Recoveries near the central 

 North Pacific (areas 28, 31-34) were mainly from a 



group of fish tagged in the same area between lat. 

 45°N and 42°N and between long. 169°E and 177°E 

 (Fig. 102). No inshore recoveries have been made from 

 this particular tagging area. 



Coastal Recoveries Subsequent to 

 Year of Tagging 



Asian stocks. — To our knowledge, no age .0 coho 

 salmon were tagged in coastal waters of Asia; conse- 

 quently, no recoveries were made of tagged coho 

 salmon following the year of tagging. 



North American stocks (Figs. 103, 104). — During 

 purse seine fishing along the coast of North America 

 juvenile coho salmon were tagged resulting in several 

 returns of tagged maturing fish in the following year 

 (Hartt, Smith, and Dell 1967; Hartt, Smith, Dell, and 

 Kilambi 1967; Hartt et al. 1969, 1970; Rothschild et 

 al. 1971). These coastal recoveries were reported only 

 from tagging locations relatively close to the shore of 

 Washington, British Columbia, southeastern Alaska, 

 and central Alaska. 



Cook Inlet to California. — Recoveries of tagged 

 coho salmon subsequent to the year of tagging were 

 made in areas from Cook Inlet in central Alaska to 

 California (Figs. 103, 104). Generally only a few 

 recoveries were made in each area and with very few 

 exceptions, the tagging locations were north or 

 westward along the coast from the point of recovery. 

 Some of the tagging locations and subsequent 

 recoveries indicated fairly long coastal migrations 

 during the juveniles' first summer at sea. Fish return- 

 ing to northern and central British Columbia (Fig. 

 103) showed juvenile migrations to the northern Gulf 

 of Alaska. Similarly, returns to southern British 

 Columbia and the Puget Sound area were tagged as 

 far north as off southeastern Alaska and the northern 

 Gulf of Alaska. Several tagged coho salmon that had 

 been tagged as juveniles in northern coastal areas 

 were taken along the west coast of Vancouver Island 

 and from Washington to California (Fig. 104).
