| dc.description | Macrobrachium rosenbergii juveniles were fed hormone-free and hormone-treated diets at 30% crude protein. Methyltestosterone (MT) was incorporated in the diets at 3 levels (25 mg MT/ kg feed, 75 mg MT/kg feed and 125 mg MT/kg feed and administered for 60 days. Growth in all treatments after 30 days post-hormone treatment showed no significant differences (P 0.05) while sex ratios were significantly different in 3 treatments : control v diet I (25 mg MT/ kg feed); diet I v diet IV (125 mg MT/kg f eed) (P¡Ý 0.05). As artificial control of growth and monosex cultures through hormones are possible tools in any cultural management, this preliminary study may inspire further exploration along these lines particularly on the culture of the giant freshwater prawn. 1 Research conducted under the FAO/NACA Secondment for Young Scientists Program Bangkok, Thailand October 1985-September 1986. 2 Research Associate-Southeast Asian Fisheries Development Center (SEAFDEC - AQD) Binangonan Research S tation Binangonan, Rizal Philippines 3106. | |
