AQUAVITAE_Fish key performance indicators for diets from fisheries by-catch valorisation

This dataset contains the key performance indicators associated with a nutritional trial performed at the Centro de Ciências do Mar do Algarve (CCMAR, Faro, Portugal) within the framework of the Cross-cutting Case Study on by-products of the AquaVitae project (New species, processes and products contributing to increased production and improved sustainability in emerging low trophic, and existing low and high trophic aquaculture value chains in the Atlantic) funded by the European Union’s Horizon 2020 Research and Innovation Programme (GA 818173). This study aimed to assess the effects of no-fishmeal (FM) diets and fish protein hydrolysates (FPHs) produced from fisheries discards on the growth performance of gilthead seabream (Sparus aurata). Two FPHs were prepared from the enzymatic hydrolysis of discards from whole-body blue whiting (Micromesistius poutassou) and gurnard heads (Trigla spp.); the former contained a higher proportion of large peptides (LP), while the latter had more small peptides (SP). Gilthead seabream juveniles (initial weight ± 8.0 g) were reared on four isoproteic (48%) and isolipic (16%) diets for eight weeks. Basal diets were a commercial-like diet (COM) and a diet based on ingredients not used directly for human consumption (FUTURE diet - FUT), without FM or soy protein concentrate. The FUT diet was further supplemented with one of the FPHs (FUTLP and FUTSP diets).
