See below brief introduction:The novel technology: Gene silencing and the BGU line:-The technology was developed at the National Institute of Biotechnology at Ben Gurion University of the Negev (BGU) in the laboratory of Prof. Amir Sagi. It is based on a recent finding of a new gene encoding an insulin-like androgenic gland hormone from M. rosenbergii (termed Mr-IAG and fully patented).The patent is licensed to Tiran Shipping (1997) Ltd with exclusive, worldwide rights to utilize the IP and to commercialize the licensed products.Silencing of this gene could cause complete sex reversal of a male into a functional neo-female. The neo-females are grown and bred to produce all-male populations. The technology does not use hormones or chemicals and it is not producing genetically modified prawns. Thus this is a completely non-GMO technology. Because it does not involve genetic modification of the organism, thereby bypassing the regulatory pipeline required of genetically-modified crops, this is a boon for monosex biotechnology. As the intervention is temporal, it is not transmissible to next generations. Indeed, this approach may be of tremendous applied merit in the aquaculture industry. Moreover, it could also form part of a sustainable solution for the management of invasive and/or pest crustacean species, where the production of non-reproducing male or female populations is sought.Experiment conducted in M. rosenbergii monosex populations resulted with significantly higher yields when all-male populations were cultured. An economic analysis of all-male population culture showed income increase by ~60% over mixed and all-female populations.
