Brown shrimp (Penaeus aztecus) were grown at densities of 3000/ha in polyculture with fish in flow-through 0.1 ha ponds. Shrimp, 104.8 † 6.81 mm in total length, were stocked with Florida pompano (Trachinotus carolinus), 67.6 † 9.32 mm in standard length (SL); Florida pompano, 58.0 † 6.13 mm SL, and black drum (Pogonias cromis), 91.9 † 11.17 mm SL; black drum, 86.3 † 10.65 mm SL; and black drum, 93.7 † 7.92 mm SL, and striped mullet (Mugil cephalus), 74.5 † 26.36 mm SL. Densities were 5000/ha for Florida pompano and black drum, and 500/ha for striped mullet. Shrimp survival ranged from 19.0 to 63.3%. Average survivals, all treatments, were poorest with Florida pompano and best with black drum in fish monocultures. Growth was excellent, averaging 0.17 g/day and similar with all fish species and combinations. |
