Evaluation of the Combined Administration of and in Diets for : Effects on Growth, Metabolism, and Digestive Functionality.

This study aimed to evaluate the combined effect of dietary and ethanol-inactivated DCF12.2 (C + V diet) in juveniles, highlighting their nutritional, physiological, and morphological effects. The results showed that the combined dietary inclusion of and significantly enhanced growth performance and feed utilization compared to the control group.

Long-Term Effects of a Short Juvenile Feeding Period with Diets Enriched with the Microalgae on the Subsequent Body and Muscle Growth of Gilthead Seabream, L.

Currently, microalgae are used in fish diets, but their long-term growth effect is unknown. In this experiment, juvenile seabream specimens were fed with microalgae-enriched diets for three months, and then transferred to a microalgae-free diet for 10 months to assess long-term effects up to commercial size (≈27 cm and ≈300 g). The juvenile diets contained at 2.

Cultivated and Wild Juvenile Thick-Lipped Grey Mullet, : A Comparison from a Nutritional Point of View.

The thick-lipped grey mullet () is a nominee fish species for aquaculture diversification in Spain because it is an omnivore and euryhaline species, but limited knowledge about the nutritional attributes of this species is available. This study aimed to characterize the chemical composition of wild and cultured fish. The muscle proximate composition, and fatty acid and amino acid profiles were assessed.

Low dietary inclusion of nutraceuticals from microalgae improves feed efficiency and modifies intermediary metabolisms in gilthead sea bream (Sparus aurata).

The aim of this work was to evaluate two functional feeds for the gilthead seabream, Sparus aurata, containing low inclusion of two microalgae-based products (LB-GREENboost, LB; and LB-GUThealth, LB). Fish (12-13 g) were fed for 13 weeks a control diet or one of the four diets supplemented with both products at 0.5% or 1%.

Partial Characterization of Protease Inhibitors of and Their Effect on Digestive Proteases of Marine Fish.

This piece of research evaluates the presence of protease inhibitors in the macroalga and provides an initial overview of their mode of action. The ability of protease inhibitors to inhibit digestive proteases of three marine fish species, as well as their capacity to hamper the hydrolysis of a reference protein by those fish proteases, were assessed. In addition, thermal stability and the mode of inhibition on trypsin and chymotrypsin were also studied.
