Figure 3 
Length-frequency distributions of adult female Argentine hake ( Merluccius hubbsi) collected from the Patagonian stock off 
Argentina in January during the years 2005-2013. The black shaded area visible beyond the gray area represents the frac- 
tion of females that would skip spawning during the spawning peak of the stock. The length-at-maturity model was applied 
in 2 ways to create the 2 overlapping areas: females in the resting stage were considered mature (black) or functionally 
immature (gray).
