Author(s): BK Mahapatra and Gopal Krishna
Abstract: The aim of this paper is to describe the development stages of the embryo and of larval period Indian ornamental fish,
Rasbora daniconius. Thus, has been characterized seven broad periods of embryogenesis - the zygote, cleavage, blastula, gastrula, segmentation,
pharyngula and hatching, respectively. These divisions highlight the changing spectrum of major developmental processes that occur since fertilization to hatching. Stages subdivide the periods and their names are based on morphological features, generally readily identified by examination in microscopy of the live embryo. The embryonic development lasted 23-24 hours in water temperature around 26-28 oC. During larval period, the main aspects were following: yolk resorption, body pigmentation and completed organogenesis, filled with gas of the swim bladder, fins differentiation, the appearance of active body movements and start of the exogenous feeding.
