Some morphometric features and length - weight relationships of F1 hybrid juveniles (Umbrina cirrosa ♀ Χ Argyrosomus regius ♂)
Abstract
In this study, length-weight relations and some morphometric characteristics of hybrid juveniles obtained by crossing of Umbrina cirrosa (Linnaeus, 1758) and Argyrosomus regius (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 * TL3.006 r= 0.99). Individuals have shown isometric growth (b=3) according to the results of regression analyze by b 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
