is located in a depth of 74 m and rises to about 6 m 

 above the substrata. 



Results 



TheHorrwt spent 18.2% of its total fishing time around 

 the platforms, compared with 18.4% over the 4 Mile 

 Reef and 2.4% over the 6 Mile Reef (Table 1). About 

 17% of all fish recorded at all 24 sites were taken 

 around the platforms, compared with 27.6% over 4 Mile 

 Reef and 3.2% over 6 Mile Reef (Table 2). 



Twenty-eight species were taken around the plat- 

 forms, compared with 34 and 17 species over the 4 Mile 

 and 6 Mile Reefs, respectively (Table 3). Rockfishes 

 (Sehastes sp.) predominated the catches at all sites in 

 both species numbers and abundance. Of all species 

 captured at the platforms, 53.6% were rockfishes, com- 

 pared with 50% at the 4 Mile Reef and 82.4% at the 

 6 Mile Reef. Of all fish taken around the platform, 83% 

 were rockfishes, compare with 96.0% and 90.8% at the 

 6 Mile and 4 Mile Reefs, respectively. Catch-per-unit-
