This study provides the first detailed table of normal development of the rosy barb embryo, from fertilization to post-hatching. We define six broad periods of embryogenesis, i.e. the zygote, cleavage, blastula, gastrula, segmentation and larval periods. These divisions highlight the changing spectrum of major developmental processes occurring during these periods. Stages that subdivide the periods are named, not numbered as in most other series. The stages and their names are based on morphological features usually readily identified by examination of the live embryo under a stereomicroscope. These provide a detailed embryological staging by morphological criteria for future studies on molecular biology and biotechnology in this species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
