SUMMARY 



1. The NUEL seining program has provided both long term and seasonal 

 estimates of the kinds and numbers of finfish inhabiting the shore 

 zone near the MNPS . Their patterns of abundance are now well 

 documented. 



2. The program has provided information on species potentially impacted 

 by impingement (silversides) , entrainment (sand lance) and the 

 thermal plume (silversides, sand lance, killifishes and fourspine 

 stickleback) . 



3. The seine data base can be characterized as having a highly skewed, 

 non-normal distribution. It cannot be characterized as having a 

 negative binomial or a log-normal distribution. Thus appropriate 

 transformations would not normalize the data for the application of 

 parametric statistical tests. Even though normal-theory assumptions 

 were violated, the program was able to detect large ( > 50%) 

 changes in shore-zone finfish populations which might be the result 

 of power plant impact. Nonparametric tests and time-series 

 (forecasting) analysis were also found useful for detecting changes 

 in the shore-zone finfish. 



4. Within the framework of the cost of the current program, modifications 

 to the seining program would not improve the detectability of the 

 program. 



5. Under three-unit operation, conditions may exist such that the 

 shore-zone finfish assemblages in Jordan Cove will be exposed to 

 the thermal plume. These conditions would exist on ebb tides 

 throughout the year, and would be unsampled under the current 

 program of sampling two hours before high tide during only eight 



months .
