Flying fish biometrics dactylopterus volitans (linnaeus, 1758) (pisces: Dactylopteridae) around cubagua island, Venezuela

Abstract:

Channel flyer Dactylopterus volitans is a fish that posses great commercial attractiveness mainly due to its muscle quality, this is why studying its biometrics is very important in order to regulate its exploitation. In present study a total of 345 specimens were examined. Fish were collected monthly from March 2002 to March 2003. The population sample was constituted by organisms of different size groups with a range between 71 and 363 mm total length (TL), with the highest percentage for the size class between 120-200 mm TL. The relative growth of the species was characterized by generally not be uniform, as some relationships majorant showed allometric growth (body width vs. total length: 4,013***), others had minorante allometric growth (head length vs. total length: -6,144*).). The species D. volitans introduced an isometric length-weight relationship, registering no change in Kn per month or by size groups.
