Age O black drum (Pogonias cromis) were stocked in polyculture with age O Florida pompano (Trachinotus carolinus); age O striped mullet (Mugil cephalus); and in monoculture in 0.1 ha flow‐through ponds. Densities were 5,000 fish/ha each for Florida pompano and black drum and 500 fish/ha for striped mullet. Pompano were harvested after 5 months of culture leaving black drum counterparts to continue in monoculture. After approximately 278 days, production of drum was 66% greater when initially grown with pompano for 145 days than for those maintained in monoculture throughout the study. The small number of striped mullet served as feeding stimuli for black drum, thus improving production 40% over drum kept in monoculture.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
