White shrimp ( Penaeus vannamei ), blue shrimp ( P. stylirostris ), and Florida pompano ( Trachinotus carolinus ) were reared in 0.08‐ha, managed nursery and monoculture and polyculture production ponds in coastal Alabama. In Trial I during 1978, a white shrimp nursery pond culled for production stock then continued for 140 days produced 2,331 kg/ha of shrimp averaging 12.0 g with a feed conversion of 1.2. Yield of white shrimp from 3 monoculture production ponds stocked at 25,000 shrimp/ha and managed for 63 days averaged 193 kg/ha with 63% survival, 3.8 feed conversion, and 11.9 g mean weight. Yield of pompano from 2 monoculture production ponds stocked at 4,925 fish/ha and maintained for 33 days averaged 23 kg/ha with 38% survival, 5.5 feed conversion, and 15 g mean weight. In polyculture, yield of white shrimp and pompano averaged 265 kg/ha with 0.9 feed conversion. The shrimp averaged 11.2 g with 90% survival, and the pompano averaged 14 g with 21% survival. In Trial II during 1979, a blue shrimp nursery pond stocked at 500,000 postlarvae/ha and managed for 47 days produced 864 kg/ha of shrimp averaging 1.8 g with 96% survival and 2.1 feed conversion. Yield from one nursery pond stocked at 165,025 fish/ha with graded pompano and maintained for 55 days was 601 kg/ha of pompano averaging 5.1 g with 71% survival and 3.0 feed conversion. Yield of blue shrimp from 3 production ponds stocked at 82,813 shrimp/ha and managed for 149 days averaged 904 kg/ha of shrimp averaging 16.0 g with 70% survival and 4.5 feed conversion. Yield of pompano from 3 monoculture pompano ponds stocked at 10,000 fish/ha and managed for 106 days averaged 741 kg/ha with 67% survival, 3.9 feed conversion, and 106 g mean weight. In polyculture, yield of blue shrimp and pompano averaged 1,285 kg/ha with 3.0 feed conversion. The shrimp averaged 14.1 g with 63% survival, and the pompano averaged 75 g with 74% survival. Crops of blue shrimp in monoculture and blue shrimp and pompano in polyculture had positive economic returns.
