and McAlister. 1959) and since Kulm and Byrne 

 (1967) found that marine sand was transported 

 by strong currents 6 miles up the Yaquina Bay 

 estuary during the winter, the season when P. 

 vetulus enter the estuary, then descent of larvae 

 into deep water, where net transport exists up 

 the estuary, may result in transport into and re- 

 tention within estuaries of English sole and 

 other species, as found for other larval fish 

 (Pearcy, 1960; Pearcy and Richards. 1962; and 

 Graham, 1972). 



In conclusion, Yaquina Bay, like many east 

 coast estuaries, is an important nursery for 

 the young of several species of marine fishes. 

 This was not apparent from a survey of plank- 

 tonic larvae, however. Only the larvae of Pacific 

 herring, a species that spawns in bays, were 

 abundant in our plankton collections in Yaquina 

 Bay. Although the pelagic larvae of flatfishes 

 were much more common in offshore than 

 estuarine waters, the juveniles of several species 

 move into the estuary in large numbers. 



ACKNOWLEDGMENTS 



We are indebted to H. F. Frolander who has 

 tenaciously conducted the plankton survey of 

 Yaquina Bay since 1960 and provided the 

 11-yr series of collections and to Joan Flynn 

 who curated these collections. We are also 

 grateful to William Johnson, University of 

 Rhode Island, who generously supplied his 

 data on juvenile fishes, to Peter Rothlisberg, 

 Greg Lough, and Dean Satterlee who were 

 essential for field sampling in 1969 and 1970, to 

 Elbert AhLstrom, Elaine Sandknop, Maxwell 

 Eldridge, and James Blackburn who helped to 

 identify fish larvae and to Sally Richardson, 

 Charles Miller, and William McNeil for their 

 helpful criticisms of the manuscript.
