 water occurred close to shore around Anacapa 

 Island, while cooler (perhaps upwelled) conditions 

 occurred slightly offshore to the east. 



Fish Distribution 



Data from our study suggest that the fish com- 

 munities of the northern Channel Islands resemble 



those of the central and southern California main- 

 land. San Miguel and Santa Rosa harbor a more 

 temperate fauna than Santa Cruz and Anacapa. A 

 number of species characteristic of southern Califor- 

 nia (i.e., Sarda chiliensis, Scomber japonims, 

 Seriola lalandei, SphyraeTia argentea) were not 

 found off San Miguel or Santa Rosa, while other 

 southern California species {Scorpaena guttata and 

 Paraiabrax dathratits) were less abundant around
