of water sampled was estimated from a TSK flowmeter. During 1974, studies were conducted to compare 

 the catches from the 0.333-mm mesh offshore sampling net and the net used at EN, and to evaluate 

 laboratory processing techniques. Results indicated that there was no significant difference between the 

 abilities of the two nets to catch eggs or larvae nor in the techniques used to process the samples (NUSCo 

 1983). Beginning in .luly 1975, an electronic flowmeter was used to measure volume of entrainment 

 samples. Sampling was limited to the discharge station, where flow velocities were high cnougli to eliminate 

 problems of poor flowrrieter response and net avoidance. Although the exact location of this station was 

 somewhat different from that used previously, a comparability study revealed that there were no significant 

 differences among density estimates made from samples collected simultaneously at the two sampling 

 locations at the discharge (NUSCo 1976a). The sampling frequency was changed from one-day and 

 one-night set of samples per week to three days and three nights per week (three replicates each, for a
