highlights the relevance of the nose-to-tail concept as a strategy to improve resource efficiency and promote circularity in aquaculture. Within this context, the biochemical composition of the liver, gonads [...] small fraction of the nutrients supplied through feed into biomass, with nitrogen retention efficiencies ranging from approximately 14 to 30 %. In addition, only about 40 % of the harvested biomass in [...] African catfish and up to 60 % in Atlantic salmon is recovered as edible fillet. The remaining fractions, including the head, skin, liver, gonads, and other tissues, are often treated as low-value byproducts
