4 Found at only one station in 1991. 
of total abundance, the 45 species captured in 1990 
fell into four general categories: category 1 (extremely 
abundant) consisted only of B. saida and made up 
76.1% of total abundance and 61.3% of total biomass; 
category 2 included five moderately abundant species 
( Myoxocephalus verrucosus, Myoxocephalus sp., E. gra- 
cilis, Gymnocanthus tricuspis, and Hippoglossoides 
robustus) and made up 18.4% and 25.8% of total abun- 
dance and biomass, respectively (Table 1); category 3 
included 13 occasional species and made up 5.9% and 
13.7% of total abundance and biomass, respectively; 
and category 4 included 26 rare species that accounted 
for only 0.46% of the abundance and <5.0% of the bio- 
mass in 1990 (Table 1). The fish in the first two catego- 
ries accounted for more than 94.4% and 87.1% of the 
total abundance and biomass, respectively. This pat- 
tern was generally reflected in the 1991 catches. 
In 1990, there was a tendency for abundance and 
biomass of all species combined to be greatest in the 
southern part of the study area and lowest in the 
northern part of the study area (Fig. 2). Seven sta- 
tions south of Ledyard Bay yielded more than 50,000 
fish/km 2 . In contrast, many stations off and north of 
Icy Cape had fewer than 10,000 fish/km 2 .
