No. 36 Yankee Shrimp Trawl Combined 

 with No. 41.5 Yankee Otter Trawl 



Division 4R, North of Lat. 50° N, 1980. The 

 median of juvenile distribution was located in the 

 240-260 m interval while that for adults was located 

 in the 180-200 m depth interval (Table 3, Fig. 

 3). 



Discussion 



The results of the analysis do not statistically sup- 

 port the hypothesis that juvenile witch flounder 

 prefer a deeper water habitat than adults, although 

 the median usually shows adults shallower than 

 juveniles. Only the shrimp trawl catches in NAFO 

 Division 4R, 1980 show juveniles shallower than 

 adult witch flounder (Fig. 2C). Combining the data
