Traditionally, manual selection of males during farming has been practiced but is labour-intensive and often fails to achieve a male-only population. The androgenic gland (AG) is pivotal for sexual differentiation and the development of male characteristics. Microsurgical removal of the AG (andrectomy) during early development can transform male prawns into fully functional neo-females. The androgenic gland-specific insulin-like hormone (Mr-IAG) is crucial for male spermatogenesis and sexual development in M. rosenbergii. RNA interference (RNAi) offers a precise method to silence gene expression post-transcriptionally, effectively inducing complete and functional sex reversal by silencing Mr-IAG. Both microsurgery and RNAi target the AG to achieve efficient sex reversal. Neo-females resulting from these methods can mate with normal males to produce all-male prawn offspring, thereby enhancing production efficiency and profitability in commercial prawn farming. <\/p>\n","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","issues_type":[34],"class_list":["post-6210","jsri-issue","type-jsri-issue","status-publish","hentry","issues_type-vol-10-1-2024","has-post-title","has-post-date","has-post-category","has-post-tag","has-post-comment","has-post-author",""],"ptb_metabox":{"ptb_jsri_issue_upload_pdf":{"url":["https:\/\/www.bhumipublishing.com\/jsri\/wp-content\/uploads\/2024\/11\/7.-Suvadip-Ghara.pdf"],"title":[""]},"ptb_jsri_issue_author":"Suvadip Ghara and Sayan Biswas","ptb_jsri_issue_keywords":"Freshwater, Prawn, Genetic Modification, All-Male Population, Selective Breeding, Monosex-Culture, Sex Reversal"},"ptb_taxonomy":{"issues_type":[{"term_id":34,"name":"Vol. 10 (1) 2024","slug":"vol-10-1-2024","term_group":0,"term_taxonomy_id":34,"taxonomy":"issues_type","description":"","parent":0,"count":13,"filter":"raw"}]},"ptb_featured_image":null,"builder_content":"","_links":{"self":[{"href":"https:\/\/www.bhumipublishing.com\/jsri\/wp-json\/wp\/v2\/jsri-issue\/6210","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.bhumipublishing.com\/jsri\/wp-json\/wp\/v2\/jsri-issue"}],"about":[{"href":"https:\/\/www.bhumipublishing.com\/jsri\/wp-json\/wp\/v2\/types\/jsri-issue"}],"wp:attachment":[{"href":"https:\/\/www.bhumipublishing.com\/jsri\/wp-json\/wp\/v2\/media?parent=6210"}],"wp:term":[{"taxonomy":"issues_type","embeddable":true,"href":"https:\/\/www.bhumipublishing.com\/jsri\/wp-json\/wp\/v2\/issues_type?post=6210"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
