Summary: Aquaculture requires new, economical, and eco-friendly protein sources to replace traditional fisheries and plant ingredients. Using agriculture by-products as protein sources would reduce land-based feed production pressure and waste production, promoting a circular economy and sustainable aquaculture.

Summary: After a meal, physiological changes occur in animals to digest and assimilate the nutrients ingested. This study investigated the activity of digestive enzymes and protein degradation systems in meagre juveniles after a single meal. The results provide information on the short-term effects of feeding and can guide scientists in planning digestion and protein degradation studies, as well as fish farmers in managing feeding protocols for A. regius juveniles.

Summary: The study found that boat noise has a significant masking effect on the acoustic communication of meagre, reducing the ability to discriminate conspecific calls when exposed to boat noise. Additionally, passing boats also lead to a decrease in chorus energy of meagre, which may ultimately impact spawning.

Summary: This study investigates the development of Chronic Ulcerative Dermatopathy (CUD) in cultured meagre fish and finds that the use of borehole water and natural seawater has different effects on the development of the disease. The study also observes that pH and CO2 are not involved in the development of CUD. Additionally, the study shows that the lesions of CUD can be resolved when the fish are transferred to natural seawater.

Summary: Systemic granulomatosis is a mysterious disease affecting the important aquaculture fish species, Argyrosomus regius, and its etiology remains unknown. Through amplicon metagenomics analysis of the 16S rRNA gene in fish kidneys, it was found that all fish had similar bacterial communities. The presence of only three significantly enriched OTUs in sick individuals, none of which were known granuloma-causing species, supports the hypothesis of a non-infectious cause of this disease in this fish species.

Summary: The study assessed the reproductive maturation of meagre reared in sea cages under routine farming conditions. It was observed that meagre males and females, produced in hatcheries and reared in sea cages, are able to spontaneously produce and release gametes. This suggests that meagre reproduction under commercial conditions could expand meagre aquaculture production, which currently relies on limited fingerling production by a select few hatcheries.

Summary: The study evaluated the spoilage status of meagre caught in January and July through sensory, microbiological, 16S metabarcoding and VOCs analysis, revealing differences in shelf-life, microbial composition, and volatile profile between whole fish and fish fillets, as well as between the two seasons. Different microbial profiles and volatile compounds were found in the two seasons, with some compounds positively correlating with storage time and others showing a declining trend. The findings provide valuable insights for stakeholders to supply high-quality meagre products in the national and international market.

Summary: Meagre is a target species in European marine aquaculture due to its high growth rates and nutritional profile, but it is highly sensitive to low temperatures. This study examined the effects of dietary phospholipids (PLs) on the growth and cold tolerance of meagre, finding that a PL-enriched diet promoted faster growth and reduced the risk of death, as well as mitigated the negative effects of fatty liver during cold challenges. These results suggest that dietary supplementation with phospholipids could improve the cold tolerance of meagre in aquaculture.

Summary: The study aimed to trace the life history of escaped meagre through otolith microchemistry, finding similar patterns of strontium concentrations between farmed and escaped fish but differences in barium concentrations at specific periods. Differences in otolith Sr:Ba ratios between farmed and escaped meagre suggested they shared the same origin but inhabited different conditions from a certain time of their life. However, individual differences in core-to-edge Sr:Ba values among escaped fish indicated they escaped in different periods, showing the potential of otolith microchemistry as a tool to trace escaped fish.

Summary: The study found that chlorinated seawater at typical concentrations can affect the behavior of juvenile seabass, resulting in a decrease in the number of fish present. While seabass are attracted to areas with chlorination when food is available, they are more likely to move away once the food supply is reduced.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.

Summary: This study developed a centrifugal microfluidic chip with on-chip RPA to detect five pathogenic microorganisms. The chip enabled the parallel analysis of six genetic markers from a single sample and allowed for the highly automated detection of multiple samples. Compared with PCR and DNA sequencing, the on-chip RPA assay showed high sensitivity and specificity for detecting multiple pathogens in shrimp aquaculture.
