trawling surveys indicate pandalid shrimp are 

 very low in abundance in outside waters (Schae- 

 fers and Smith 1954; Hitz and Rathjen 1965; 

 Ronholt et al.^). From 1969 to 1975, no pandalid 

 shrimp were commercially landed in this area 

 (Ronholt et al. footnote 1). However, in the inside 

 waters of southeastern Alaska around Petersburg, 

 near the southern portion of my sample area, pan- 

 dalid shrimp have been fished commercially since 

 1916 (Barr 1970). In northern inside waters, pan- 

 dalid shrimp have also been reported as abundant 

 (Ellson and Livingstone 1952). Similarly, since 

 commercial fishing records were first kept in the 

 1920's, Pacific herring have been abundant in in- 

 side waters south of Cape Spencer (Reid 1971). No 

 catches of Pacific herring have ever been reported 

 for outside waters north of Cape Spencer appar- 

 ently because of the scarcity of Pacific herring in 

 this area.
