To determine if the data from the trawl and seine programs were, 

 in fact, providing adequate information to meet the objectives, an evaluation 

 of these programs was undertaken. The results from this evaluation are pre- 

 sented in this report along with recommendations for changes necessary to 

 more efficiently meet the objectives.

MATERIALS AND METHODS 

 Sampling sites 



A total of eleven different sites have been sampled at one time or 

 another since 1973. They were designated 1, N2, 4, NB, JC, 7, TT, 9, 

 10, IN, and BR and are shown in Fig. 1. 



Collections 



Beginning in March, 1973, 15-minute hauls were made biweekly using 

 a 9.1m Wilcox otter trawl with a 0.6cm codend liner at stations 1, 4, 

 JC, 7, TT, 9 and 10. From March through May a single 15min tow was made 

 at each station. In an attempt to increase the precision of the catch 

 estimates, replication was begun in June 1974. During June and July 

 duplicate hauls were made at one station chosen randomly. In August, 

 three tows were taken at one randomly chosen station. 



About this time, investigations were being pursued to determine the 

 best location for the proposed intake of Unit 3. In September of 1974 

 station IN was added and duplicate tows were begun at TT, 10 and IN (all
