Biomethric Parámeters of Wild Wreckfish (Polyprion americanus)

Abstract

The wreckfish (Polyprion americanus) is a much appreciated species from the gastronomic point of view. The renowned quality this fish is well known, both nationally as in the international market. This makes wreckfish a good candidate for marine aquaculture diversification. Preliminary results on the biology (Wakefield et al., 2013) and culture (Peleteiro et al., 2014) of this species suggest that this is a fast grower. Wreckfish also acclimates easily to captivity and handling, and despite their large sizes, no mortality related to handling has been observed. This species readily accepts prepared diets in captivity, and is characterized by its low metabolism and inhabiting great water depths. The present research was designed to obtain information on biochemical composition, biometric parameters, sexual differentiation and maturity of wild caught wreckfish, which are important for a success culture of this species.
