Table 3. — Comparisons of catches and lengths (mm SL) of walleye pollock 

 larvae with gear, time of day, and depth from the vertical distribution study, May 

 1983. 



Stable at 6.90°-6.15°C (Fig. 8). Nearby, salinity 

 and density showed a very gradual increase with 

 depth. 



The pattern of water movement in the survey 

 area, derived from the temperature and salinity 

 observations, indicated a general southwest flow 

 of water at all depths. In the area of larval concen- 

 tration, most of the flow tended southward, fol- 

 lowing the deep trough from Shelikof Strait 

 across the continental shelf between the Semidi 



Islands and Cherikof Islands (S. Kim^). 



Diet and Feeding of 

 Walleye Pollock Larvae 



Eighteen different food items were identified in 

 walleye pollock larvae sampled at the diel sta-
