composition of these fishes. This larval fish 

 survey offers some basic information relating 

 to the larval fish population in Humboldt 

 Bay. Further research is presently needed 

 for development of more efficient sampling 

 methods, for gathering information on the 

 distribution of fish larvae within the estuary 

 and how it changes with time, and for under- 

 standing how physical-chemical conditions 

 affect distribution. 



ACKNOWLEDGMENTS 



We wish to thank C. S. Apperson for his 

 assistance in the data acquisition, which often 

 took place under inclement conditions. We 

 also greatly appreciate the help provided by 

 E. H. Ahlstrom and his staff. Dr. Ahlstrom's 

 critical review and comments on the manu- 

 script were especially helpful. 



This study was supported by the California 

 Cooperative Fisheries Unit, Humboldt State 

 College, and was submitted in partial ful- 

 fillment of the Master of Science degree re- 

 quirement.
