In 2 trials during 1976-1979, juvenile red drum (Sciaenops ocellata) were reared to marketable size (454 g) in 0.08-ha, brackish-water ponds at the Claude Peteet MaricuIture Center. In Trial I, survivors from a nursery pond were stocked in 2 production ponds, fed a commercial feed, and harvested when 394 or 532 days old. Less than I% of drum from the first harvest were marketable, and yield was 787 kgl ha with 21O-g mean weight, 89% survival, and 2.8 feed conversion. Twenty-one percent from the second harvest were marketable, and yield was 1,062 kgl ha with 335-g mean weight, 75% survival...

Production of gulf killifish (Fundulus grandis) was investigated from 17 November 1977 to 10 July 1978 in 0.08 ha, brackish-water, earthen ponds at the Claude Peteet Mariculture Center. Gulf killifish averaging 30.7 g and stocked at 12,500fishjha deposited eggs on Spanish moss spawning mats from 21 March through 16 May 1978. Fifty mats with eggs were transferred to a hatching pond which yielded 82,500 juvenile killifish averaging 0.1 g at harvest on 16 May. Stocked at 250,000 fishj ha in 3 grow-out ponds on 19 May and fed a commercial minnow feed, the juveniles averaged 2.0 g (marketable...
