flatfishes (Wakefield 3 ). Trawl samples collected 

 from this area between May 1977 and September 

 1979 were utilized for our work. A 1.5 m beam 

 trawl fitted with a recording odometer wheel 

 and a 7 mm stretch mesh liner was employed for 

 all but one of these collections. On one occasion, 

 22 March 1979, we obtained samples using a 

 small otter trawl which also had a 7 mm stretch 

 mesh liner. On each sampling date, 10-min tows

covering about 750 m 2 surface area were made at 

 several depths between the 9 and 30 m isobaths 

 (0.9 and 2.7 km offshore, respectively). Fish were 

 preserved in 10% buffered Formalin 4 immedi- 

 ately upon collection. No regurgitation of gut 

 contents was observed. The daily time of sam- 

 pling varied between 0830 and 1800 h. 



From the 85 trawl collections obtained during 

 this 29-mo period, we selected 31 for examina- 

 tion. Several criteria were used in choosing these 

 samples. In keeping with an overall goal of the 

 Pleuronectid Project to obtain detailed informa-
