were collected on rising tides during daylight hours 
by using a modified 3.7-m plumb staff beam trawl 
with a double tickler chain (Gunderson and Ellis,

proximate speed of 0. 5-1.0 kn from both the skiff 
and the trawler. 
Sample processing 
Substrate type, water depth, bottom temperature, 
bottom salinity, and distance from the mouth of the 
nearest bay were evaluated for each station. Sedi- 
ment samples were analyzed, as in 1991, by means 
A 
Rock sole 
B
