Figure 18. Annual cumulative density (no./500 m ) of grubby larvae at EN and NB. 



impingement estimates for 1984 and 1985 were relatively low and did not include Unit 1 impingement 

 because the sluiceway was operational, but those estimated for 1976 and 1977 were smaller. 



The grubby was taken in trawls primarily from November through April except at JC where it was 

 taken throughout the year (Fig. 20). Almost 75% were caught at the nearshore stations JC, NR and IN 

 (Table 15). Total catch of grubby taken in trawl for the two-unit operational period was 5,483 fish (Table 

 14) and annual catches ranged from 191 to 866. Annual mean catches did not show any trend over the 

 1976-1985 period (Fig. 21) and the observed fluctuations could not be related to MNPS two-unit operations.
