Station, which had the highest forecast error, the 1983 data were above 

 the 95% confidence interval. 



The grubby was found throughout the year near MNPS . They spawn 

 locally throughout the winter and attach eggs to bottom substrates 

 (Table 2). Thus, grubby eggs were not identified in plankton samples 

 although larvae were abundant. Abundance of grubby in the trawl and 

 impingement programs was seasonal with high numbers occurring during 

 winter. All regression models provided a description of the observed 

 fluctuations of grubby. However, the high model errors associated with 

 trawl models produced very wide confidence intervals and limited the 

 validity of these models. Entrainment and impingement models were more 

 accurate and suggested no change had occurred in the 1983 abundance of 

 grubby compared to previous years.
