Monthly visual SCUBA transects were conducted at two sites, Intake Pipes and Pumpernickel Cove, at Santa Catalina Island (Figure 1) while on SCUBA from . Fixed transects 100 m in length were established at both sites at 9 m and 18 m depth.

To collect a whole lot more real investigation to your certain habits and you will relevant colour models, 108 (fifty boys, 58 female) grownups had been grabbed from 20 so you can and you can listed in a great 700 [yards.sup.3] outside, drifting web-pen situated in Catalina Harbor, Santa Catalina Island, Ca (Figure 1). grams. Quast 1968), and you can away from several observations regarding aggregations held into Scuba out-of 2000 so you’re able to 2002.

Kelp trout was basically intimately monochromatic for most of the entire year. Adults and you may teenage some body gathered and noticed inside slip, cold weather, and you can spring season weeks was basically basically olive-green to help you khaki brownish towards the their top, dorsal, and you may lead part.
