Fig. 8. Density-dependent growth (19802003) and survival (19932003) in young-of-the-year Chesapeake Bay striped bass. A. Mean lengths in September in relation to abundance (catch-per-unit effort, Maryland Department of Natural Resources seine-survey data). Mean lengths at ~ 120 days posthatch vary inter-annually by ~50 mm. B. Instantaneous daily mortality from September to the following August in relation to abundance (cpue, MDNR seine-survey data). Mortality rates vary>2-fold inter-annually with respect to abundance. (Figure modified from Martino and Houde, 2004, Figs 14 and 15). |
