Wet biomass of each fish species harvested in each fishpond design (in kg per pond), their initial stock in brackets (kg per pond), and fish yield at the end of the experiment (kg ha−1). Total dry biomass per m2 was estimated based on a conversion factor of 5 (i.e., 1 g of dry mass per 5 g of wet mass) to compare it more easily to that of invertebrates (Cresson, 2017). Adapted from Jaeger et al. (2021).
