Mono-sex culture of giant freshwater prawns (Macrobrachium rosenbergii) gives more benefits than mixed-sex culture because of high market demand for male prawns. Unfortunately, sex differentiation in crustaceans could not obviously be observed in their early larval stage. Therefore, sex segregation or sex reversal techniques need to be developed and timing for sex differentiation in M. rosenbergii during larval development needs to be examined. In this study, three genes related to male reproductive hormone (IAG, MRR and MAL) were isolated and amplified from terminal ampulae (TA) of adult male M. rosenbergii. The male specific transcripts demonstrated that they could be used …
