Population dynamics of yellowtail scad, Atule mate (Cuvier 1833) in Marudu Bay, Sabah, Malaysia

The yellowtail scad, Atule mate, forms important fisheries throughout the Indo-Pacific region. To know about the stock status of A. mate in Malaysia, various population parameters were measured, by utilizing length-frequency data, that included asymptotic length (L∞), growth coefficient (K), mortali...
