Influence of Production Strategy on Gross Waste Output and Temporal Pattern of Gilthead Seabream (Sparus Aurata) Farming: Implications for Environmental Management

This study compares the farm management model used in Mediterranean gilthead seabream (GHSB; Sparus aurata) industry (S1)—stepped entry of juveniles throughout year with several production cycles and fish ages overlapping a single farm—with that salmon (S2)—the whole is filled are same age at once fallowing period between rearing cycles—in terms waste by coupling digestibility coefficients growth, feeding, eating behavior models into mass balance model. We considered total C, N, P content different fractions (particulate dissolved wastes). The model, which simulated real farming conditions, showed relevant quantitative qualitative differences both strategies, stocked biomass water temperature as main drivers, amount feed wasted chewing most fraction differentiating distinguishing feature. discuss influence strategies on some key performance environmental aspects, such benthic recovery, breakdown life cycle pathogens, adaptability to climate change. Our results suggest changing GHSB industry’s necessary for its sustainability.
