Recovering wasted nutrients from shrimp farming through the combined culture of polychaetes and halophytes

Abstract The bioremediation and biomass production of organic extractive organisms (polychaetes Arenicola marina, Hediste diversicolor and halophyte Salicornia ramosissima) was assessed in an integrated multi-trophic aquaculture (IMTA) framework. Culture trials were performed outdoors using the nuti...
