Figure 8.— (A) Log length (TL, mm) versus age (0-40 d) of laboratory-reared giant kelpfish 

 larvae. * = one fish. N = 130. Regression equation: Log TL = 0.814 + 0.013 (days). 

 F = 1,211.9, P < 0.0001. (B) Growth of laboratory-reared giant kelpfish (0-9 mo), length 

 (cm) versus age (months). * = one fish. N = 100. Regression equation: TL = 0.379 + 

 1.482 (months). F = 2,230.8, P < 0.0001. 



pling (Fig. 13). Contingency tests of independence 

 showed that numbers of individuals in various size 

 classes differed significantly with season in 1981-82 

 and 1982-83. Juveniles appeared in significant num- 

 bers during the spring and summer months. These 

 data agreed with observations on spawning and 



appearance of larvae in the water column, indicating 

 that most Catalina Island kelpfish in these years 

 spawned from January through May. During spring 

 and summer, a large portion of the population was 

 estimated to be 1 and 2 yr old, composed of in- 

 dividuals of reproductive age. During the fall
