Abstract
Age, growth and mortality of the Striped mojarra (Eugerres plumieri) from the Cienaga Grande de Santa Marta (Colombia) and the catch's information from january to december 1997 were analyzed for sites 1 and 2, respective]y. By using the ELEFAN I, calculated asymptotic length (L¥) ranged 40.8 and 40.6 cm total length (TL) and growth rate (K) ranged 0.78 and 0.79 y-I. By using the Wetherall's method, L¥ ranged 45.7 to 41.7 cm TL. Applying Pauly's equation, the values for natural (M), fishing (F) and total (Z) mortalities ranged 1.439 to 1.453 y-1, 1.614 to 1.865 y-l and 3.053 to 3.318 y-l respectively. The length at capture (Lc) was 20.5 cm TL and the exploitation rates (E) were 0.53 and 0.57 and for both sites; this values confirm over fishing of resource.
