Comparative Retina Stratification in Embryos, Larvae and Adults of Alburnus chalcoides
The present investigation considered retina structure in embryos, larvae and adult Alburnus chalcoides. Histological samples of retina were provided from adult fish, different stages of embryonic and larval development. Eye primordia formed from ectoderm at 16 hours after fertilization (16hAF) and then developed to eye cups. Initial eye cup which contained undifferentiated retina began to form ...
