between HL and FL and between ML and FL for 

 sablefish, Greenland turbot, and arrowtooth floun- 

 der are shown in Figures 5—7. 



Length-frequency distributions from the 1988 sur- 

 vey data for sablefish, arrowtooth flounder, and 

 Greenland turbot are shown in Figures 8-10. Each fig- 

 ure depicts three different length-frequency distribu- 

 tions for each species: 1) those for all areas fished (EA, 

 B-I, B-II, B-III, and SH) including stations that had 

 reports of killer whale interference with longline op- 

 erations without estimated length specimens (all ar- 

 eas; Figs. 8A, 9A, and 10A); 2) size distributions of un- 

 damaged fish for all stations (station numbers are pre- 

 sented in Table 3) that reported killer whale depreda- 

 tion (all stations; 8B, 9B, and 10B); and 3) size distri- 

 bution of partially consumed fish and whose estimated 

 length was based on the calculations made through the 

 above formula of HL and ML (partially consumed fish; 

 Figs. 8C,9C, and 10C). 



Average length of sablefish was 635.7 mm FL for 

 all areas fished, 607.5 mm FL for undamaged fish at 



stations where killer whale depredation was evident, 

 and 633.1 mm FL for the partially consumed fish 

 (Fig. 8, A, B, and C). Significant differences were 

 found between average lengths of damaged fish and 

 undamaged fish for all stations where killer whale 

 predation was evident (£=19.65, P<0.05). However, 

 no significant differences were found between aver- 

 age lengths of damaged fish and undamaged fish for 

 all areas fished (£=0.43, P>0.05). The average length 

 of damaged fish was significantly larger than that of 

 undamaged fish at stations where killer whale dep- 

 redation was evident (£=19.65, P<0. 05), but the total 

 average length was about equal to that for all areas 

 fished. 



Average length of arrowtooth flounder was 528.3 

 mm FL for all areas fished, 506.5 mm FL for sta- 

 tions fished where killer whale depredation was evi- 

 dent, and 575.2 mm FL for fish that were preyed 

 upon. Significant differences were found between 

 average lengths of damaged fish and undamaged fish 

 (£=7.71 and £=10.99, P<0.05). The average size of
