Chronology of meiosis and spermiogenesis in a fresh-water teleost fish, Colisa fasciata (Bloch and Schneider)

Abstract

The duration of individual stages of meiosis and spermiogenesis in Colisa fasciata (Bloch and Schneider) was calculated autoradiographically by following the kinetics of H3-TdR labelled spermatocytes in vivo. The leptotene lasts for less than 0.5 day, zygotene even for shorter period and pachytene for 1.86 +/- 0.13 days. The transition from diplotene to anaphase II requires about a day. The spermiogenesis is completed within 6.43 days. The labelled spermatozoa were detected at 9.68 d post injection, which is the approximate total duration of meiosis and spermiogenesis.
