Female condition and fecundity estimation 
Batch fecundity estimates obtained for Argentine 
Hake females collected during January 2010 and 2011 
ranged between 40,500 hydrated oocytes (29 cm TL) 
and 2,550,000 hydrated oocytes (95 cm TL). The anal- 
ysis of covariance applied to compare the coefficients 
of the relationship of BF to TL obtained for each year 
did not show statistical differences (P>0.01); therefore, 
data from 2010 and 2011 were pooled to estimate all 
the regression analyses. The relationship between BF 
and TL was curvilinear, fitting better to a power model 
(Fig. 2A, Table 1). The relationship of BF to GW was 
linear, and, in the case of BF to age, a power model was 
fitted (Figs. 2B and C, Table 1). 
A positive power relationship was observed be- 
tween BF and the HSI (Fig. 2D, Table 1). In the case 
of BF and Kn, the relationship was linear and sig- 
nificant (P<0.01), but a low r 2 was obtained (Fig. 2E, 
Table 1).
