Size of wild and hatchery chum salmon (Oncorhynchus keta) fry caught by 
beach seine in littoral habitat of Taku Inlet, Alaska, by year during the out- 
migration 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; and (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. 
P= 0.028), but no significant differences were found in 
2005 (P-0.54). 
Distribution, size, and condition of wild chum 
salmon fry in relation to temperature, salinity, 
and chum salmon abundance 
Sea surface temperature and salinity followed patterns 
expected in Southeast Alaska in the spring during 
snowmelt (Meehan and Siniff, 1962; Murphy et al., 
1997). Sea surface temperature generally increased 
throughout the season in littoral and neritic habitats 
in all locations and was warmer in the outer inlet than 
the inner inlet. Sea surface temperature ranged from 
3° to 8°C in late April and increased to 7-12°C in late 
May and June in the inner inlet; in the outer inlet, it 
ranged from 4° to 9°C in late April and increased to 
9-14°C in late May and June. Sea surface temperature
