Feeding and growth dataset of Gilthead Seabream (Sparus aurata) fed with local shellfish in diets of juvenile

The data were collected from an experiment carried out on juveniles of Gilthead Seabream (Sparus aurata), reared in a Recirculating Aquaculture System composed of three fish tanks. Gilthead seabream were fed three treatments, one per tank: a control commercial feed (with fishmeal and fish oil) (C), a plant-based feed (P), or P + fresh mussel flesh (M). The dataset presented is composed of: 1. Individual fish growth parameters (live weight, length at fork, Fulton’s condition factor (K)), at stocking (S, May 9th 2019) and harvest (June 24th 2019) for each treatment (C, P and M). 2. Overall fish performances measured in group (batch weight, mean weight). 3. Daily quantities of feed delivered for each treatment.
