Limited information has become available on the survival of monosex (female) grass carp (Ctenopharyngodon idella) reared in earthen ponds. Monosex fish produced in 1975 (Stanley 1976) were reared 27 months in earthen ponds at the Fish Farming Experimental Station, Stuttgart, Arkansas. Periodic transfers of these fish to different ponds afforded the opportunity to obtain survival information. Thomas and Carter (1977) reported first-year survival percentages of 22.9 to 60.2% (average 34%) for fry stocked in six 0.1-ha ponds in June and July 1975 in a test of different stocking densities and pond conditions. Overall, of 31,887 3-mm fry stocked. 10,035 survived to reach the large fingerling stage (80-250 mm) when they were removed from the ponds in April 1976.
