Stations 10, 11, <strong>and</strong> 13 corresponded to those areas sampled in 1983 for the <strong>Knik</strong> <strong>Arm</strong><br />
<strong>Marine</strong> <strong>Studies</strong> Report. Two beach seine sets were made at each station. Table 1 lists all<br />
species/life history stages of fish captured.<br />

The composition <strong>and</strong> abundance of fish in beach seine catches had shifted relative to the<br />
summer sampling events. Juvenile salmonids were no longer abundant, <strong>and</strong> of those<br />
observed, most were small sockeye between 53 <strong>and</strong> 63 mm fork length. The dominant<br />
species was larval longfin smelt, which were observed at all but one station. Most of these<br />
fish were transparent, measuring between about 50 <strong>and</strong> 75 mm fork length, <strong>and</strong> were quite<br />
abundant at some of the stations. Adult smelt up to 160 mm were also observed at most
