Day samples only through the first week of April; day and night samples dunng the remainder 

 of April; night samples only duritig the remainder of the season. 



were made twice weekly (Monday and Thursday or Tuesday and Friday). In 1984 and 1985, from the 

 beginning of sampling (mid to late February) through the fu-st week in April, single tows were made during 

 the day twice weekly within 1 h of low slack tide. During the last 3 wk of April, single-bongo tows were 

 made twice weekly day and night. The day samples were collected within 1 h of low slack tide and the 

 night samples during the second half of a flood tide. During the remainder of the season until the 

 disappearance of larvae at each station, tows were made twice a week only at night during the second half 

 of a flood tide. 



laboratory sample processing has varied (Table 4). Through 1977, whole samples were processed 

 and all winter flounder larvae were measured. Subsequently, samples have been split based on the 

 abundance of larvae and up to 50 winter flounder larvae were measured. When a subsample of larvae 

 was measured, the length -frequency distribution was adjusted by sample density. Prior to 1983, measure- 

 ments were in total length and since then have been in standard length (tip of snout to end of notochord). 

 The difference between total and standard length measurements were only apparent for larvae in the latter 

 stage of metamorphosis when the caudal fin rays extended past the end of the notochord; these larger 

 larvae were collected infrequently. From 1973 through 1976, both paired 333- and 505-nm samples were 

 processed, but length measurements taken only in 505-|im samples m 1976. In 1977 and 1978, only the 

 333-nm samples from the paired 333- and 505-^im mesh nets were processed. From 1979 through 1982,
