Descripción: Biological parameters and spatial variation of H. arguinensis were estimated inside the Ria Formosa, Portugal. Data collected during visual census (November 2012 to March 2014) and random samplings (February to March 2014) were analyzed. The average sizes were estimated in six localities with a total range between 4 and 48 cm. Three sites showed significant diferences in the average size: Armona, showing the highest mean and Barinha and PFE with the smallest mean (27.4, 17.5 and 21.7 cm respectively, p < 2.2e-16) Asymptotic population length L?=70 cm and growth coeficient k=0.87 were estimated. The growth pattern showed seasonality using Hoenig’s function. The coverage of mud and sea grass (Z. Noltii, and C. nodosa) were the variables explaining better the diferences in abundance of H. arguinensis among sampled sites, demonstrating the importance of these sea grass species in the persistence of the species in the Ria Formosa.
