Nitrogen removal techniques in aquaculture for a sustainable production (2007, background): “Around 75% of the feed N and P are unutilized and remain as waste in the water (Piedrahita, 2003; Gutierrez-Wing and Malone, 2006).”
The impact of stocking density and dietary carbon sources on the growth, oxidative status and stress markers of Nile tilapia (Oreochromis niloticus) reared under biofloc conditions (2020, background): “Intensive farming depends on high fish densities with the use of large quantities of high-protein levels diets (25–55%) aiming for increasing productivity in closed or semiclosed systems to overcome the limit of water and lands resources (Avnimelech et al., 2008; Dawood, 2016; Delong et al., 2009; P”
Sustainable Intensification of Aquaculture through Nutrient Recycling and Circular Economies: More Fish, Less Waste, Blue Growth (2021, background): “Released ammonia can also be further broken down into nitrite (NO2 -) and nitrate (NO3 ) by biological activities occurring in the water column (Piedrahita 2003; Dauda et al. 2019).”
Discharge of nutrient wastes from salmon farms: environmental effects, and potential for integrated multi-trophic aquaculture (2012, background): “…technologies of cage culture have been significant in European aquaculture over recent decades; for instance, the mean economic feed conversion ratio (FCR) for the Norwegian salmon industry was 2.08 in 1974 but can now reach as low as 1.0 to 1.1 (Enell 1995, Piedrahita 2003, Islam 2005).”
Treatment of fishpond water by recirculating horizontal and vertical flow constructed wetlands in the tropics (2011, background): “These fish species are relatively tolerant to poor water quality such as low DO and high TAN concentrations (Piedrahita, 2003).”
Integrated Dynamic Aquaculture and Wastewater Treatment Modelling for Recirculating Aquaculture Systems (2009, background): “This will be 10 especially relevant in areas where water supply and/or effects of nutritional 11 loads on surrounding aquatic systems limit the present scope for aquaculture 12 production (Piedrahita, 2003).”
Biofloc technology in aquaculture: Beneficial effects and future challenges (2012, unknown): “of uneated feed + excretion) (Piedrahita, 2003)”
Anaerobic digestion of sludge from intensive recirculating aquaculture systems: Review (2010, background): “The solids originating in the RAS are composed mainly of fish excretions and a small percentage of uneaten feed; and its volatile (organic) fraction ranges from 50 to 92% (Gebauer, 2004; Gebauer and Eikebrokk, 2006; Mirzoyan et al., 2008; Piedrahita, 2003).”
Bio-flocs technology application in over-wintering of tilapia (2009, background): “Holding dense fish populations with limited water exchange gives rise to a substantial build up of waste, comprising uneaten feed and feces, as well as other metabolic residues including ammonia excreted by the fish (Read and Fernandes, 2003; Piedrahita, 2003; Sugiura et al., 2006).”
Environmentally sustainable land-based marine aquaculture (2009, background): “RAS ability to effectively m anage, collect and tre a t n u tr ien t w astes th a t accum ulate during th e fish grow th, is a key factor in th e ir future developm ent as m ainstream env ironm en tally sound fish p roduction system s (Piedrahita, 2003; van Rijn, 1996).”
