Summary: Despite limited research, this study found that vitamin K is important for growth and bone health in gilthead seabream larvae. Feeding larvae with 4.98 mg kg(-1) of vitamin K-3 resulted in the highest growth, while higher levels of vitamin K-3 reduced growth and survival. The incidence of bone anomalies decreased as the level of vitamin K-3 increased, with the optimal level being 5 mg kg(-1). However, high levels of vitamin K-3 (22.9 and 58.51 mg kg(-1)) caused deformities, reduced mineralization, and imbalances in bone health-related gene expression.

Summary: This study evaluated the effects of adding crude or hydrolysed Arthrospira platensis biomass to the diet of gilthead seabream fry. The results showed that the inclusion of A. platensis in the diet had positive effects on fish growth, muscle composition, digestive functionality, and immune activities. It reduced muscle lipid oxidation, increased digestive enzyme activities, improved gut morphology, and enhanced lysozyme activity in the liver, suggesting improved protection against infectious diseases.

Summary: Swimming has physiological effects on farmed fish, but the potential link between swimming and oxidative stress is still poorly understood. This study investigated the impact of different moderate swimming conditions on the antioxidant status of gilthead seabream, revealing that swimming modulated the activity of antioxidant enzymes in the liver and skeletal muscle. Adequate swimming conditions were found to minimize oxidative stress in gilthead seabream.

Summary: The present study aimed to evaluate the effect of dietary supplementation using bile salts on growth and feed performance, fat accumulation and tissue condition in gilthead seabream. It was found that the supplementation of 0.06% bile salts in the diet significantly increased the fish's body weight and decreased the level of perivisceral fat. Furthermore, the bile acid profile in the gallbladder and anterior intestine was modified by the dietary supplementation of bile salts.

Summary: The gilthead seabream, as a prominent species in Mediterranean aquaculture, has gained increasing research attention due to its growing production volume and aquafarming technologies. Various studies have contributed to the understanding of its functional and biological characteristics, resulting in improvements in reproductive success, survival, and growth in aquacultural practices. Despite the progress made in the industry, challenges remain in hatchery conditions, leading to significant economic losses during intensive culture initiation. Given the importance of this species and the persistent challenges, a thorough review is necessary to consolidate knowledge and address distribution, life cycle, genetics, aquaculture methodologies, economic dimensions, and cultivation challenges.

Summary: This study evaluated the effects of dietary protein/carbohydrate ratio and feeding frequency on the growth, metabolism, and economic efficiency of gilthead seabream juveniles. The results showed that feeding a diet with a protein/carbohydrate ratio of 40%/20% twice a day was the most suitable strategy, as it improved fish growth and economic efficiency.

Summary: The study found that replacing fish meal with poultry by-product meal did not significantly affect growth performance, feed digestion, digestive function, and intestinal microbiota of gilthead seabream juveniles, but it did improve the economic efficiency of the diets.

Summary: This study evaluated the effects of feeding frequency and dietary protein/carbohydrate ratios on intestinal histomorphology, microbiota profile, and digestive and oxidative stress-related enzyme activities of gilthead seabream. The results showed that feeding frequency and diet composition had no significant effects on intestinal histomorphology and microbiota, but influenced the activity of digestive enzymes. It is recommended to feed gilthead seabream juveniles with a diet containing 40% protein and 20% carbohydrates, twice a day.

Summary: Juvenile fish body shape experiences rapid change followed by a stable period before becoming adults. The correlation between juvenile and adult body shapes ranges from 0.22 to 0.76. The heritability estimates of the final phenotype ranged from 0.370 to 0.511, with a heritability of 0.173 for the phenotypic integration rate. The study demonstrates a substantial additive genetic component in the variance of ontogenetic trajectories.

Summary: This study assessed the effects of dietary vitamin D-3 on the growth, calcium absorption, mineralization, and skeletal anomalies in gilthead seabream larvae. The results showed that an optimal level of vitamin D-3 improved larval survival, calcium and phosphate levels, and vertebral mineralization while reducing the incidence of skeletal anomalies.

Summary: The study evaluated the effect of dietary protein source and protein/carbohydrate ratio on gilthead seabream appetite regulation and metabolism. It found that fishmeal-based diets promoted brain gene expression, while plant-based diets promoted liver lipid deposition and carbohydrate metabolism.

Summary: It is known that intensive farming exposes fish to multiple sources of stress, increasing their susceptibility to pathogens and disease outbreaks, which can lead to economic losses. In recent years, research has focused on using bioactive compounds from microalgae, plants, and microorganisms as dietary supplements to improve fish growth performance, health, and immune system. The use of natural immunostimulants is considered a promising alternative to promote fish health, productivity, and sustainability. This study evaluated the effects of adding Halobacterium salinarum, a potential probiotic strain, in the diet of farmed gilthead seabream on growth and immune responses.
