Science. 10 SOUTHERN CALIFORNIA ACADEMY OF SCIENCES 1200 i 1000 - ⦠Bycatch O Fishery âPredicted. 200 -i 100 > |-ioo H ^-200 â 300 -400 J 8 e Age (yrs) Fig. 5. (top) Age at length data by source and the von Bertalanffy growth model calculated from 492 samples of Gulf corvina. (bottom) Plot of residual values by source for length at age (observed-predicted) data included in the growth model. (F-ratio = , p < ) and GFW(F-ratio , p < ) (Figure 9). However, in 2010, BF was not significantly related to TL (F-ratio = p = ) or GFW (F-ratio = , p = ). For the combined 2009 and 2010 data BF was again significantly dependent on both length (F-ratio = , p < ) and GFW (F-ratio = , p < ). The interaction term of the ANCOVA comparing BF and length between years was not significant (df = 54, F-ratio = , p = ) but the subsequent analysis without the interaction term indicated that BF was significantly correlated to year (df = 55, F-ratio = , p < ) and length (df = 55, F-ratio = , p < ). The interaction term of the ANCOVA comparing BF and GFW between years was not significant (df = 54, F- ratio = , p = ) but the subsequent analysis without the interaction term indicated that BF was significantly correlated to year (df = 55, F-ratio = , p < ) and GFW (df = 55, F-ratio = , p < ). Discussion The collective results of this study indicate that the Gulf corvina is a fast growing sciaenid fish that attains sexual maturity at a relatively small size (200 mm) and young age (2 yrs). With respect to reproductive pattern, the species is best described as a.
