Summary: This study demonstrates that juvenile sea bass exposed to oil spills exhibit transient behavioral impairments, with a dose-response relationship observed. Recovery capacities were seen within the first 10 days post-exposure, although fish may require more time for full recovery. The alterations in behavior may be attributed to neurosensory or physiological defects caused by oil exposure, leading to sedative behaviors resembling anesthesia.

Summary: This study examined the phenotypic changes and divergence of escaped sea bass from farmed conspecifics. The study found that most escapees had sizes overlapping with farmed fish, but some grew larger in the wild. Feral sea bass tended to converge towards a similar body shape, possibly due to initial starvation, phenotypic plasticity, and selection against maladapted phenotypes.

Summary: The present study aimed to determine the effectiveness of genetic selection for growth in European sea bass in response to a challenge with an alternative diet. The results showed that European sea bass selected for 7 generations performed better in terms of growth, with decreased fat content and increased nutritional value of flesh. The dietary treatment had little effect on fish growth performance, indicating successful replacement of fishmeal and fish oil. Therefore, multi-trait genetic selection can improve the ability of European sea bass to adapt to alternative feeds with low fishmeal and fish oil.

Summary: Functional ingredients, such as nucleotides and nucleic acids, have shown potential for improving fish meal aquafeed formulation in Mediterranean aquaculture. In a study on European sea bass juveniles, the addition of nucleotides and nucleic acids to the feed increased growth performance and enhanced lipid efficiency. These ingredients also had prebiotic effects on the gut microbiome, promoting beneficial bacteria. However, the optimal dosage and combination of nucleotides and nucleic acids in fish meal require further investigation.

Summary: This study aims to investigate the effects of a 100% plant-based diet on hepatic DNA methylation in trout and evaluate whether these changes depend on fish genetic background. The results show that a plant-based diet induces changes in the hepatic DNA methylation of two trout lines, which may be attributed to either decreased feed intake or the dietary composition effect.

Summary: Genetic improvement of feed efficiency in fish farming is crucial for its economic and environmental sustainability. This study validated a method to evaluate individual feed efficiency based on individual rearing in aquariums under restricted feeding. The results showed that individual feed efficiency had an impact on group feed efficiency, and feed efficiency was heritable but did not have significant associated QTLs. Additionally, feed efficiency was genetically negatively correlated to viscera yield. These findings support the use of individual feed efficiency measurement in aquariums as a reliable phenotyping method for genetic improvement of feed efficiency.

Summary: Global warming is expected to increase heatwaves in fish farms, leading to more frequent and intense occurrences of acute hyperthermia and hypoxia in fish. These conditions can result in growth losses, increased pathogens pressure, and mortality. Selective breeding shows promise in improving resistance to non-optimal water quality, but the specific traits need further characterization before inclusion in selection programs. This study found significant variation in resistance to acute hyperthermia and hypoxia among genotypes of rainbow trout, with stability in rankings observed over a year. There was no overall relationship between resistance to these two stressors, suggesting no strong genetic trade-offs.

Summary: Hypoxia poses a significant threat to the aquaculture sector and results in economic losses. This study focused on exploring the genetic potential for improving hypoxia tolerance in rainbow trout through a genome-wide association study. Several quantitative trait loci (QTLs) were identified, but they explained a relatively small percentage of the variance. However, the heritability of hypoxia tolerance was estimated to be moderate, suggesting the possibility of genetic selection to improve this trait. Additionally, potential candidate genes related to hypoxia tolerance were proposed.

Summary: Selective breeding programs have been initiated for the Pacific oyster Crassostrea gigas, using genomic tools to improve growth and disease resistance. The study evaluated the potential of genomic selection (GS) for growth-related and shell color traits in commercially selected populations. The results showed a high correlation between growth-related traits and low correlation with color traits. The accuracy of prediction was higher with the genomic model compared to the classical model, indicating the potential of GS in mixed-family breeding programs for C. gigas.
