scientist are giving “ sex changes ” to prawns so Farmer can reap the economical benefits of producing faster growing and substantive male . Just a twelvemonth after the process made it possible , Asian farmers have fully bosom this offbeat method to increase profits .
The subprogram requires two chief stagecoach so as to make an all - male family of gargantuan freshwater prawns ( Macrobrachiumrosenbergii ) . It all starts with the androgenic gland , an organ unique to crustaceans that produce a hormone that regulates sexual differentiation and the production of manful reproductive organs . The endocrine is suppressed by put in a corpuscle that silences the expression of the cistron that codes for its product . This cutting - border proficiency is called temporal gene quieten .
This subroutine allows scientists to create “ neo - females , ” essentially prawn that are genetically manful but with all the lady prawn bits needed to reproduce . These neo - female person are then breed with normal males , which makes all of their offspring male .
The project was developed by a squad of scientist at the Ben - Gurion University of the Negev in Israel . Thescientific researchwas nail and bring out last twelvemonth , howeverReutershas reported that this new proficiency is take hold in the Asiatic food industry .
Professor Amir Sagi , who channelise the research group , said prole can inject around 2,000 prawn a twenty-four hour period by hand in Israel , where they are then embark out to Vietnam , China and India . The prawn can resign thousands of egg each , so over several round , millions of male prawns can be get – although only the inject generation will be affected from the gene silence . It ’s estimated that the development could help increase a James Leonard Farmer ’s income by 60 % .
“ The vantage of this technology is that with using all male with that technology is that we do not have to employ any chemicals nor any endocrine and it is a non - GMO , saying that it is not genetically modifying the organism , ” Sagi toldReutersin book of facts to the all - virile contemporaries that hatch .
