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 the Mediterranean gilthead seabream (GHSB; Sparus aurata) industry (S1)—stepped entry of juveniles throughout the year with several production cycles and fish ages overlapping in a single farm—with that used in the salmon industry (S2)—the whole...
