characteristics of hybrid juveniles obtained by crossing of <i>Umbrina cirrosa </i> (Linnaeus, 1758) and <i>Argyrosomus regius </i> (Asso, 1801) via
artificial fertilization under aquaculture conditions were investigated.
Lengths, weights and condition factors of 39 hybrid juvenile specimen varied
between 26.12 and 48.67 mm, 0.7 and 0.99 g, 0.81 and 1.09 respectively.
Length-weight relationship (W) was calculated (0.000009 * TL <sup>3.006 </sup> r <sup> </sup>= 0.99). Individuals have shown isometric growth ( <i>b </i>=3) according to the results of regression analyze by <i>b </i> value. All 10 morphometric
measurements presented significant differences between the examined species in
this study at the end of biometrical analyses except distance of maxilla and
pectoral fin (MPL) (P<0.05). However, the strongest correlation was found
between head length (HL) and total length (TL) (P<0.05). As a result, body
height of hybrid fish was respectively lower than the parent species and length
was shorter compared to Mediterranean populations indicating growth values were
equal to those of natural populations </span> <span style="font-size:8pt;font-family:’Arial Narrow’, sans-serif;"> </span> </p> <p> </p> </div>}, number={3}
