Different species of fish have characteristic and predictable time and depth habits. Kelp 

 bass, Pardlabrax Clathrattis , (solid lines) show extensive vertical distribution at night. 

 During the day, however, they remain above the thermocline. (Curves based on 24-hour 

 summer TV observations taken on 2-minute counts at 5-foot intervals throughout the 

 water column.) Pile perch, Rhacochilus vaccO , (dashed lines) observed over the same 

 period reveal o diurnal distribution opposite to that of kelp bass. The perch show a wide 

 vertical daytime range, although the main population mass remains near the bottom. They 

 are rarely observed during the evening hours.
