Abstract

During the year of 2004, 747 landings of artisanal fishery with handline were sampled in San Andrés Island, revealing that wahoo, Acanthocybium solandri, is the second pelagic species in importance, contributing with approximately 14% of the production, as December, January and March are the months that have the highest contributions to the catches. In regard to the biological aspects, growth was analyzed from length and weight of 280 individuals, obtaining an average of 110 cm TL and 5 kg (PE), and with an asymptotic length of 159,3. As for the trophic habits, the stomach content of 43 individuals were analyzed, indicating that 93% of the alimentary items were fish and 7% mollusks, and with the Index of Relative Importance showing that the most representative preys in the diet correspond to pelagic fish of the families Carangidae, Exocoetidae and Scombridae. The presence of the parasite Hirudinella ventricosa in more than 60% of the stomachs is to note. In reference to the reproductive aspects, it was obtained a 1:1 sex proportion, an average length of first sexual maturity of 92 cm TL and the fecundity oscillated between 360.346 and 1´326586 oocytes for females of 105 and 128 cm TL respectively. Also, it is inferred that it reproduces all year long, with peaks in January and February.
