ANOVA. The parametric ANOVA are robust tests which aren't affected by 

 slight departures in normality and are much more powerful than non- 

 parametric tests (Sokal and Rohlf 1969; Green 1979). The differences 

 between these two analytical approaches should be examined further and 

 conflicting viewpoints should be reconciled with one approach recommended. 

 This suggested evaluation should also take into account a third viewpoint 

 expressed in NUSCo (1982) , namely that these data are autocorrelated and 

 that a time-series analysis is the most appropriate technique of all. 



IMPINGEMENT MONITORING PROGRAM 

 An analysis of the impingement program from its inception in 1971 

 through the present has been recently prepared and has details regarding 

 changes in sampling methodology and frequency and data collection (see 

 Impingement Program Evaluation) . The winter flounder was one of the 

 most abundant fishes impinged at Millstone with an estimated total of 

 71,653 from 1972 through 1981 at Units 1 and 2. It was particularly 

 abundant in 1979 with 24,076 (33.6% of the total) taken. Estimates from 

 1977 through 1981 ranged from 6,181 to 9,631. Most were taken during 

 the winter when they were particularly abundant in local waters. 



Since 1977, three samples per week have been taken to estimate the 

 impingement of species collected at Millstone. Since the current program 

 was designed to determine the number of organisms of all species impinged 

 at Millstone, sampling effort was equally distributed throughout the 

 year. If, however, one or more species are deemed more important than 

 others because of abundance or value to a fishery, then it would be 

 possible to redistribute sampling effort to the match the changing 

 temporal abundance and variability of these species. Abundance and
