Figure 2. Abundance of the major items in the diet of juvenile (1-10 cm) <strong>and</strong> adult (11-40 cm) scup collected during<br />
NEFSC bottom trawl surveys from 1973-1980 <strong>and</strong> 1981-1990. Abundance in the 1973-1980 samples is defined by mean<br />
percent prey weights, <strong>and</strong> in the 1981-1990 samples as mean percent prey volume. The “Arthropoda” are almost entirely<br />
crustacea; see text for discussion of specific taxa involved. The category “animal remains” refers to unidentifiable<br />
animal matter. Methods for sampling, processing, <strong>and</strong> analysis of samples differed between the time periods [see Reid et<br />
al. (1999) for details].
