The Atlantic Horse mackerel Trachurus trachurus (Linnaeus, 1758) is subject to considerable fishing pressure. under strong fishing pressure, the objective of the research is to establish the species morphological characterization: the growth model, sex-ratio and the body condition factor, using standard morphometric methods and truss network analysis. 1494 samples were collected from the North Moroccan Atlantic coast, sampling was carried out from July 2021 to July 2022 at the port of Tangier and Larache (35°47, 33°89), indeed individuals total length measured between10 and 41 cm and the body weight presented between 35 and 500 g, All morphometrical analyses showed similar results, The values for males, females and the total sample showed that the growth of T. trachurus was minor, which that mean the weight grows less quick than the length, The condition factor was calculated indicating the smallest values were observed in the range of Total length between 10 and 19 cm.
