Spermatophore regeneration in black tiger shrimp.

Abstract

Reproduction is a main area where science can contribute to the growth of aquaculture and provide effective solutions for industry problems. Thus, many research projects have focused on the reproductive biology of farmed species. However, most researchers focused on female reproduction – possibly due to the obvious reproductive dysfunction of females under captivity. In female shrimp, vitellogenesis and oocyte maturation are processes that demand high levels of energy. Conversely, in males, sperm production is believed to consume less energy. Males use up more energy for sex competition and female guarding. Yet male-related reproductive dysfunction and infertility have been increasingly reported in commercial The authors recently carried out a series of studies at the experimental shrimp hatchery facility of the Central phore regeneration in black tiger shrimp Institute of Brackishwater Aquaculture to characterize the reproductive capability of male black tiger shrimp, Penaeus monodon, by documenting changes in sperm quality in relation to consecutive regeneration, molting cycle and length of rearing period.
