G─ůsior W., Kompowski A., 1982. Biological and fishery-related observations on jack mackerel, Trachurus declivis (Jenyns, 1841) stock during spawning of south-east Australia. Acta Ichthyol. Piscat. 12 (2): 3-20.

Modal individual length in a spawning population of Trachurus declivis observed was 31 cm. Age groups III and V were found to dominate in the stock. The following parameters of the von Bertalanffy growth equation were estimated: L = 47.18 cm; K = 0.166; to = -1.966 yr. Total mortality (F + M) was 0.343, 0.397, or 0.453 depending on the estimation method adopted and length at first capture assumed. The stock contained more males than females.
