Results from the growth model indicated that growth rates in males and females were similar. However, the asymptotic length (Loc) predicted for females (1086 mm) was higher than that for males (913 mm). Offish sampled, about 75% were greater than 600 mm and over 65% were age 5 or older. These results are likely a product of the narrow size range (c. 650-1013 mm) offish captured by the commercial gill net fishery, which targets adult rh â n 1-2,2-3 2-3,3-4 3-4,4-5 4-5,5-6 5-6,6-7 6-7,7-8 Width Differences Assessed Fig. 7.
