| Resumo: |
Growth parameters based on age assignation, length-weight relationship and mortality rates of castañeta Cheilodactylus bergi were studied. Samples came from landings at Mar del Plata Port(Buenos Aires province, Argentina) during 1989, and from a research cruise carried out in the Argentine-Uruguayan Common Fishing Zone(CFZ) during 1991. Castañeta is a longeval demersal species. The growth parameters of von Bertalanffy special model were: 1) Lý 31.95,34.69, 32,30; 2) K 040, 033, 039; and 3) t0 0.00, -0.16, 0.03 corresponding to males, females and all fish respectively. The rates of total mortality (Z) were 0.18, 0.16 and 0.17 for males, females and all fish, respectively. Because of the low rate of exploitation during the study, this values can be used as indicators of natural mortality (M)
