Abstract
We conducted the histological observations on development of sperms in white leg shrimp L. vannamei, a prime aquaculture species. The testes have three distinctive stages of sperms, spermatogonium, spermatocytes and spermatids, in addition the nurse cells. The spermatozoa were observed in distal vas deferens (DVD) and in ejaculatory duct. The spike of the spermatozoa is prominent. We concluded that development of the sperms is a continuous process all along the reproductive tract.
