Abstract

ABDO-DE LA PARRA, María Isabel et al. Embryonic Development of Pargo Colorado Lutjanus colorado (Jordan & Gilbert, 1882). Int. J. Morphol. [online]. 2014, vol.32, n.3, pp.902-908. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022014000300025.

The Colorado snapper (Lutjanus colorado) is one of the most commercially important fish species in México and it is considered a suitable candidate for culture. Until now, no research has been carried out on its reproduction, larviculture and fattening in captivity. This study is the first description of embryonic development of this species under controlled conditions. Fertilized eggs of Colorado snapper are pelagic, spherical and transparent and contain one drop of oil. Eggs measured 0.77±0.09 mm and the drop of oil 0.14±0.01 mm. First cell division occurred at 0.05 h post-fertilization (HPF), hatching at 17.22 HPF under the above described conditions. Larvae total length (LT) was 1.8±0.1 mm. Embryonic development of this species was similar to other lutjanidae species. These results provide basic information for developing the necessary biotechnology for commercial seed production of the Colorado snapper.

Keywords : Blastulation; Gastrulation; Organogenesis; Hatching; Lutjanus colorado.
