Figure 7. Abundance of juvenile <strong>and</strong> adult scup relative to bottom water temperature <strong>and</strong> depth based on Massachusetts<br />

inshore bottom trawl surveys (spring <strong>and</strong> autumn 1978-1996, all years combined). Open bars represent the proportion of<br />

all stations surveyed, while solid bars represent the proportion of the sum of all st<strong>and</strong>ardized catches (number/10 m 2 ).<br />
