Fork length (FL, mm) and weight (g) of hatchery and wild chum salmon 
( Oncorhynchus keta) fry caught by Kodiak trawl in neritic habitats of Taku 
Inlet, Alaska, during the outmigration period for wild fry (late April to 
mid- June): (A) fork length (mm), inner inlet; (B) fork length, outer inlet; 
(C) weight (g) inner inlet; (D) weight, outer inlet. Early hatchery chum 
salmon were released near the inlet on 10 May and 17 May 2004 and 
9-12 May 2005. Late hatchery fry were released 22-26 May 2004 and 
22 May to 3 June 2005. No late hatchery fry were caught in the inner 
inlet in either year. 
wild fry abundance had no significant effect on weight, 
whereas hatchery fry abundance had a significant posi- 
tive effect on weight (Table 2). Sea surface temperature 
and salinity were positively and negatively correlated 
with weight, respectively, but neither variable was sig- 
nificant in the multiple regression analysis. 
Condition factor of wild fry in the inner inlet was not 
correlated with either wild or hatchery fry abundance 
in 2004 (Table 3). In the multiple regression analysis, 
however, when salinity (which had the highest bivariate 
correlation) was included into the model, wild abun- 
dance had a significant and positive effect on condi- 
tion factor. Hatchery abundance was not significant in 
the model. In 2005 in the inner inlet, condition factor 
was significantly correlated with wild fry abundance, 
but not with hatchery fry abundance (Table 3). In the
