Praneeth Silva, unless I am mistaken what you are referring to, the dark pigments are melanocytes. They occur frequently in wildtype zebrafish embryos, even in the yolk sac. Here is some more information about the genetics of melanocyte formation in zebrafish: Article Genetic Analysis of Melanophore Development in Zebrafish Embryos
