The experiment was conducted in two phase. In phase-I, two experiments were performed in six aquaria (50fry\/aqurium) with two replicates. In experiment A, aquarium -1 was used as control in which no hormone was given while in aquaria 2 and 3, the MT were given@ 60 and 70 mg MT\/ Kg of feed containing 30 % crude protein.  In experiment B, aquarium - 4 was used as control in which no hormone was given while in aquaria 5 and 6, the MT were given@ 60 and 70 mg MT\/ Kg of feed containing 40 % crude protein. Both the experiments were run parallel in six aquaria for 30 days. After that, the fry were shifted to 6 earthen ponds (phase-II) in which feed was given without hormones on the same protein level as in phase-1, to monitor their growth performance for 183 days. At the final harvest frequency of males and females was determined by morphomatric characteristics and examination of gonads.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783846510018\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783846510018","offer_id":39485476929629,"sku":"9783846510018","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/40bd584c-8f56-4a21-b703-5d83464e8322.jpg?v=1770363112","url":"https:\/\/shop.autorenwelt.de\/products\/masculinization-in-nile-tilapia-oreochromis-niloticus-von-farkhanda-khan","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
