They ranked eighth among trawl-caught fish. Anchovies were most 

 abundant in trawl catches at NB and IN (Table 3) . Impinged fish (modal 

 length of 80 mm) were primarily adults, while trawled fish (modal length 

 of 30 mm) were young of the year (Fig. 5).

Fluctuations in log-transformed anchovy catches in various 

 monitoring programs were modeled using harmonic regression techniques. 

 Data from the trawl and seine programs were insufficient for modeling. 

 The egg and larval models included season (see Table 4) and the 

 impingement models included flow, as multiplicative regressors (Table 

 6) . The models of egg and larval abundance explained over 90% of the 

 variation during the modeling period; the impingement models explained 

 less variation (73-76%) . The forecast errors for the impingement models 

 (42-48%) were higher than those resulting from the egg and larval models 

 (8-21%). Some 1983 data exceeded the 95% confidence limits; the eggs 

 appeared earlier than predicted and impingement levels were two orders 

 of magnitude higher than forcasted (Figs. 6 and 7).
