intervals for the impingement models (Fig. 11). Because the seine data 

 were not equally spaced in time as needed to forecast fluctuations using 

 time-series techniques, estimates were made for months not sampled using 

 techniques described in the Analytical Methods section. All seine 

 models included 6-mo harmonic components. Seine models had high R^ 

 values with only the model for station SS accounting for less than 80% 

 of the variation. Forecast errors were low for the 1983 seine data. In 

 two cases (JC, and SS) the forecast error was lower than the model 

 error. The 1983 seine data were all within the 95% confidence 

 intervals. Models for trawl-caught silversides showed lower R^ than 

 seine or impingement models. Because few silversides were trawled at BR 

 and TT, modeling was not done for these two stations. Annual cycles 

 were significant at all trawl stations modeled except JC and this 

 station had the highest model and forecast errors. The 1983 trawl data 

 for silversides exceeded the 95% confidence range at NR and IN (Fig. 12).
