Jaenicke and Celewycz: Marine distribution and size of juvenile Pacific salmon 



89 



ters et al. (1978) noted that production predictions 

 were critically sensitive to the width of the coastal 

 band within which salmon migrate during their first 

 summer at sea. We recommend additional sampling 

 be conducted from June through September to bet- 

 ter document 1) the width of the coastal band of ju- 

 venile salmon migrations through the summer and 

 2) the timing of offshore migrations beyond 37 km 

 from the outer coast. 



Acknowledgments 



We thank the biologists and technicians who helped 

 in the field and laboratory. We also thank the crew 

 on the NOAA RV John N. Cobb and FV Bering Sea 

 for their cooperation during seining operations. The 

 FV Bering Sea cruise was part of a cooperative 

 coastwide survey from California to Southeast 

 Alaska with W Pearcy, Oregon State University. 



We especially acknowledge the review of the 

 manuscript by A. Wertheimer.
