P^IGURE 3.-Number of successful 30-mm bottom trawl sets per (rectangle) in NAFO Div. 2J, 3K, and 3L by Canadian research vessels 



from 1977 to 1983. 



15 fish. The highest mean catch was 23 and oc- 

 curred in rectangle W27. This was based upon 

 only 1 set however (Fig. 3). On the other hand, the 

 second highest mean catch per set was 15 fish in 

 the adjacent rectangle V27, based upon 47 sets 

 (Figs. 3, 4). It should be noted also that some of 

 the highest mean numbers per set occurred due 

 east of Cape Freels along the dividing line be- 

 tween Div. 3K and 3L. Catches in the southern 

 portion of Div. 3L were insignificant with most 



rectangles having mean catches of about 0.1 fish/ 

 set. 



Distribution by Depth and 

 Temperature 



Distribution by 100 m depth intervals of witch 

 flounder is presented in Figure 5. For Div. 2J, 

 witch flounder were caught in depths ranging 

 from 101 to 900 m. However, only the depth range
