| Importance | Zebrafish is an excellent model organism for the study of developmental biology and biomedical research, monitoring clinical trial for diseases and drug discovery and development. This species poses transparent embryo and larvae and highly fertile with up to 200 embryos every 7 days and undergo rapid external development. (Tavares and Santos, 2013). |
