Differential Reshaping of Skin and Intestinal Microbiota by Stocking Density and Oxygen Availability in Farmed Gilthead Sea Bream (): A Behavioral and Network-Based Integrative Approach.

Fish were kept for six weeks at three different initial stocking densities and water O concentrations (low-LD, 8.5 kg/m and 95-70% O saturation; medium-MD, 17 kg/m and 55-75% O saturation; high-HD, 25 kg/m and 60-45% O saturation), with water temperature increasing from 19 °C to 26-27 °C. The improvement in growth performance with the decrease in stocking density was related to changes in skin and intestinal mucosal microbiomes.

Successful cryopreservation in biodegradable containers of sperm from aquaculture Mediterranean fishes.

We aimed to evaluate the efficiency of hard-gelatin and hard-hydroxypropyl methylcellulose (HPMC) capsules as biodegradable alternative containers to plastic straws in European eel (Anguilla anguilla), gilthead seabream (Sparus aurata) and European sea bass (Dicentrarchus labrax) sperm cryopreservation. Sperm samples from each European eel (n = 12) were diluted 1:8:1 (sperm: extender P1+5 % egg yolk: methanol). Gilthead seabream (n = 12) samples were individually diluted in a cryoprotectant solution of 5 % MeSO + NaCl 1 % plus BSA (10 mg mL) at a ratio of 1:6 (sperm: cryoprotectant solution).

Understanding how high stocking densities and concurrent limited oxygen availability drive social cohesion and adaptive features in regulatory growth, antioxidant defense and lipid metabolism in farmed gilthead sea bream ().

The study combined the use of biometric, behavioral, physiological and external tissue damage scoring systems to better understand how high stocking densities drive schooling behavior and other adaptive features during the finishing growing phase of farmed gilthead sea bream in the Western Mediterranean. Fish were grown at three different final stocking densities (LD, 8.5 kg/m; MD, 17 kg/m; HD, 25 kg/m).

The potential of a combination of pungent spices as a novel supplement in gilthead seabream () diets to aid in the strategic use of fish oil in aquafeeds: a holistic perspective.

This work studied the potential of a combination of pungent spices (capsicum, black pepper, ginger, and cinnamaldehyde) to be used as a supplement in diets of gilthead seabream (; 44.1 ± 4.2 g).
