Fig 5. Change in distribution of adult Urophycis chuss (Red Hake) in the Northeast U.S. Shelf Ecosystem.

Locations of strata with significant differences in annual relative proportions of adult Urophycis chuss between 1977–1987 and 1999–2008 in the spring (A) and fall (B) were used to examine directional shifts. Linear regressions of the Kruskal-Wallis chi-square (Chi H) for each stratum were tested for each direction: along-shelf (C), cross-shelf (D), and depth (E) to determine if slopes were significantly different than zero for each season, and classify the significant directional shifts. Adult Urophycis chuss shifted significantly northward, inshore, and deeper in the spring and fall.
