Tarletonbednia crenularis was the only spe- 

 cies of mesopelagic fish collected in large 

 numbers at stations 8 and 17. About 84 percent 

 of the total catch was taken at the surface 



(table 10). Similarly, Pearcy (1964) found high 

 concentrations of this species at the surface 

 off the coast of Oregon.
