Length-Weight Relationship and Growth of the Striped Seabream Lithognathus Mormyrus (Linnaeus, 1758) From Al Haneah Fish Landing Site, Mediterranean Sea, Eastern Libya

Length-weight relationship and growth characteristics of the striped Seabream Lithognathus mormyrus (Linnaeus, 1758) was established using 164 fish collected from Al-Haneah (eastern Libya, Mediterranean Sea) artisanal catch during March  to October 2015. The power relationship between total weight (W in gm) and total length (L in cm) for L.  mormyrus was highly isometric: W = _0.0132L^{^3.0008}   (R2 = 0.8291). The length based von Bertalanffy equation of the order: L_t = L∞ (1 – exp (-K (t –t₀ ))) was Lt = 30.465 (1 – exp (-0.159 (t + 2.5435))). The weight based equation was W_t =  374.2523  (1 – exp (- 0.159 (t  + 2.5435))) ^3.0008. The growth index was low: ɸ = 2.169.
