creased to peak values in deeper strata ( 111-185 m, great- 

 er than 10 times the catches in the shallowest strata), 

 and were low in the deepest stratum (>185 m). Converse- 

 ly, autumn survey catches were highest in the shallowest 

 stratum (27-55 m) and lowest in the deepest stratum 

 (>185 m). These patterns were also generally significant 

 within both geographic regions (Table 4). 



In the pairwise comparisons of the winter and spring 

 surveys, catches were significantly greater at 111-185 m 

 than in other depth zones. In the 27-55 m depth zone, au-
