Shore-zone Seines , 1969 - 1982. 



The seine sampling program, established in 1969 to monitor the 

 shore-zone fish, consists of triplicate collections taken in the two 

 hours preceding high tide at six stations in February, May, June, July, 

 August, September, October and December. This report is an evaluation 

 of the seine program to determine if the shore-zone finfish assemblages 

 are sampled adequately enough to describe their long term natural 

 fluctuations and to distinguish these from plant induced changes. The 

 analyses indicated that the data base has a highly skewed distribution 

 due to a high frequency of small catches and a low frequency of large 

 catches. In addition, significant autocorrelations exist in the data 

 base as well. These two characteristics limit the application of appro- 

 priate normal-theory statistical tests in detecting year to year changes. 

 Further, during three-unit operation on the ebb tide, the thermal plume 

 is expected to encompass nearby shore zones that previously were uninflu- 

 enced by this effect. A redistribution of sampling effort is suggested 

 so that potentially impacted areas can be more intensively studied prior 

 to the start-up of Unit 3. 



Trawls , 1973 - 1982. 



The trawl sampling program, established in 1973 to monitor the 

 demersal fish, consists of triplicate collections taken biweekly at six 

 stations. This report is an evaluation of this program to determine if 

 the demersal finfish assemblages are sampled adequately enough to describe 

 their long term natural fluctuations and to distinguish these from plant 

 induced changes. It was determined that the program provided long term 

 and seasonal estimates of finfish that were typical of the benthic and
