Estudio del desarrollo embrionario del pez amatitlania nigrofasciata (Perciformes: Cichlidae)

Abstract

Embryonic development in fish makes it possible to determine the chronological process of the morphological formation of a new organism. In previous studies, they show that between species of the same order or the same family of fish there are differences such as the time it takes to develop embryonic development, which makes it necessary to perform studies to know the embryology of each species in particular. Therefore, the objective of the present work was to describe the most important stages of the embryonic development of the convict cyclic (Amatitlania nigrofasciata), through optical microscopy. This species was kept in the ichthyology - embryology laboratory of the El Bosque University under controlled conditions for its reproduction (Valbuena et al., 2012). The result was the description of 24 stages of embryonic development from cleavage to brood, a new record was obtained for this species of oral suckers and segmental circulation after hatching; The study culminated in the development of a table of the embryonic development of the aforementioned stages.
