were collected with a 9.1 x 1 . 2-m knotless nylon mesh (1.3 cm) beach 

 seine from October through December 1982, and from February through 

 September 1983. Triplicate 30-m hauls were made parallel to the beach 

 within the 2-h period before high tide at each station. These methods 

 were comparable to those used since October 1976. Fish in each haul 

 were identified to the lowest practical taxon, counted, and measured to 

 the nearest mm. From 1969 through 1980, only standard length 

 measurements were made. During 1981 through 1982 both standard and 

 total lengths were measured. Linear regression equations fitted to the 

 standard length data were used to estimate the total lengths for the 

 period 1976-1980. 



Ichthyoplankton sampling 



The eggs and larvae of various finfish were sampled from October 

 1982 through September 1983 using 0.333-mm mesh plankton nets. 

 Entrainment ichthyoplankton samples were collected at least weekly, 

 alternating between Units 1 and 2 discharge (EN) . Samples were 

 collected with a 1.0 x 3.6-m conical plankton net deployed using a 

 gantry system described previously (NUSCo 1978) . Volumes filtered 

 approximated 400 m^ and were measured with four General Oceanic 

 flowmeters (Model 2030G) arranged inside the net hoop to account for 

 vertical and horizontal flow variations. Volumes were calculated from 

 the four flowmeters and averaged for each sample. One day and night 

 sample was collected per week in October through December and four day 

 and four night samples per week in January through September. Offshore 

 ichthyoplankton samples were collected at NB (Fig. 1) with paired 0.61 x 

 3.3-m cylinder-cone plankton nets, mounted on an unbridled bongo frame. 

 Volumes filtered approximated 300 m^ and were determined with General 

 Oceanic (Model 2030G) flowmeters. Two bongo tows (1/day, 1/night) 

 were made biweekly September through March. Four bongo tows (2/day, 

 2/night) were made weekly from April through August. One replicate of 

 each tow was processed. The EN larval data used in this report are from 

 the period October 1976 through September 1983; the NB larval data are 

 from October 1978 through September 1983. Egg data are from May 1979 

 through September 1983.
