The use of marine aquaculture solid waste for nursery production ofthe salt marsh plants Spartina alterniflora and Juncus roemerianus

---

Recent technological advances in marine shrimp and finfish aquaculture alleviate many of the envi-ronmental risks associated with traditional aquaculture, but challenges remain in cost-effective wastemanagement. Liquid effluent from freshwater aquaculture systems has been shown to be effective inagricultural crop production (i.e., aquaponics), but few studies have explored the potential for reuse ofmarine aquaculture effluent, particularly the solid fraction. The purpose of this study was to investigatethe use of marine aquaculture solid waste as a nutrient source for the nursery production of two salt toler-ant plants commonly used in coastal salt marsh restoration, Spartina alterniflora (smooth cordgrass) andJuncus roemerianus (black needlerush). Specifically, measurements of plant biomass and tissue nitrogenand phosphorus allocation were compared between plants fertilized with dried shrimp biofloc solids andunfertilized controls, as well as between plants fertilized with dried fish solids and unfertilized controls.In both experiments, S. alterniflora plants fertilized with marine aquaculture solids showed few significantdifferences from unfertilized controls, whereas fertilized J. roemerianus plants had significantly greaterbiomass and absorbed and incorporated more nutrients in plant tissue compared to unfertilized controls.These results suggest that J. roemerianus may be a suitable plant species for the remediation of marineaquaculture solid waste.
