Abstract

NAVIA, Andrés F; GIRALDO, Alan  and  MEJIA-FALLA, Paola A. Notes on the biology and diet of Mustelus lunulatus in the central fishing zone in the Pacific Ocean off Colombia. Investig. mar. [online]. 2006, vol.34, n.2, pp.217-222. ISSN 0717-7178.  http://dx.doi.org/10.4067/S0717-71782006000200024.

Specimens of Mustelus lunulatus captured in the trawling fishery of a shrimp vessel in the central zone in the Pacific Ocean off Colombia were analyzed. The size, weight, growth pattern, sexual proportion, stages of maturity and diet were determined. The captured specimens were between 50 and 125 cm, the sexual proportion was 1:1, and the isometric-type length-weight relationship was described by WT = 0.005·LT2.92. In all, 13 food items were identified in the stomach content, with the stomatopods (Squilla panamensis and S. parva) being the dominant taxonomic group in number and weight
