Weight-Length Relationships of Seven Fish Species (Teleostei: Sparidae, Mullidae, Carangidae) of Western Mediterranean Sea (Oran Bay, Algeria)

No information currently exists on the weight-length relationships of Sparidae: Axillary seabream Pagellus acarne (Risso, 1827), bogue Boops boops (Linnaeus, 1758); Mullidae: Red mullet Mullus barbatus (Linnaeus, 1758), surmulet Mullus surmuletus (Linnaeus, 1758) and Carangidae: Atlantic horse mackerel Trachurus trachurus (Linnaeus,1758), Mediterranean horse mackerel Trachurus mediterraneus (Steindachner 1863), Blue jack mackerel Trachurus picturatus (Bowdich 1825), seven commercial fish species of Oran Bay in Western Mediterranean Sea.Data are presented for the first time for that region of the Mediterranean Sea to contribute and help comparative growth studies.Samples were collected from commercial catches at Oran Bay fisheries in Algeria.The values of the slope b in the lengthweight relationship, W=aL b ranged from 2.841 to 3.296.The coefficients of correlation r 2 were comprised between 0.85 and 0.97."a" and "b" parameters were compared with other fishing sites for the same fish species with Froese plot [Log a=ƒ(b)].
