| Sumario: | The aquaculture industry is a complex sector that offers challenges largely unknown to other traditional livestockagriculture operations. Hundreds of species are cultivated on a commercial scale using a wide variety of productionsystems. Rearing animals in an aquatic environment greatly complicates monitoring of growth, standing biomass,feed delivery, and waste outputs. Feed delivered but not consumed by the animals cannot be recovered or evenappropriately quantified. The nutritional composition of fish feeds varies considerably which complicatescomparison of feed efficiency values amongst operations and even, to some extent, between production cycles.Wastes produced by fish culture operations are often difficult to contain and may, potentially, contribute toenvironmental degradation of fragile aquatic ecosystems.
