Resistance to viral nervous necrosis in European sea bass ( Dicentrarchus labrax L.): heritability and relationships with body weight, cortisol concentration, and antibody titer

Table 2 Univariate estimates of additive genetic variance (\({\sigma }_{a}^{2}\)) and heritability (\({h}^{2}\)) for the investigated traits

MORT post-challenge mortality (0: alive, 1: dead), BW body weight (g) at 548 days post-hatching, SRHC square root of serum cortisol concentration (ng^0.5/ml^0.5), AT antibody titer (sample to positive ratio of the optical density values, OD 450 nm)
^aThe median of the marginal posterior density has been used as a point estimate of the parameter
P (\({h}^{2}\)> 0.1): probability of \({h}^{2}\)> 0.1
