Summary: This study investigated the effects of broodstock and larval diets on larval growth, survival, competence, metamorphosis, and fatty acid and sterol compositions. The results showed that broodstock fed with Rs + C produced more larvae compared to those fed with Rs + Tw. Larval growth, survival, competence, and settlement were influenced by both broodstock and larval diets. Larvae fed with T + C originating from broodstock fed with Rs + C exhibited the best overall performance.

Summary: To address the issue of high mortality of hatchery-reared Pacific bluefin tuna during the winter, researchers developed an advanced spawning technique by manipulating environmental cues in a land-based tank. This technique allowed the fish to have better thermal tolerance and spawn 2 months earlier than usual. Parentage analysis revealed successful breeding events involving at least 2 females and 5 males.

Summary: The speed vernalization protocol developed in this study greatly reduces generation time for winter crops by optimizing light and temperature conditions, allowing for up to five generations per year. This has significant implications for biological research and breeding outcomes.

Summary: The Mar Menor lagoon in Spain has experienced severe eutrophication, leading to a decline in the population of flat oysters and loss of their habitats not only in the lagoon but also in European seas. The Mar Menor Oyster Initiative aims to understand the nutrient extraction capability of flat oysters and develop tools for restoration and bioextraction. The RemediOS project, part of the initiative, focuses on obtaining oyster seed from local broodstock for population restoration. This study presents the results of the first attempt at reproducing Mar Menor local broodstock in captivity.

Summary: The decline of European flat oysters not only affects the coastal economies and marine environment of Europe, but also poses challenges in restoring their habitat. The importance of disease-resistant, tolerant, and resilient oysters in restoration efforts is discussed, highlighting the need for collaboration among experts to establish consensus on definitions and applications. Failure to act now may lead to the spread of disease to new locations and populations in the future, underscoring the significance of robust definitions in marine management regulations.

Summary: This study investigated temporal and spatial abundance patterns of European oyster larvae in Loch Ryan, Scotland, UK, finding that temperature is the most significant seasonal predictor of larval abundance, peaking at 617 degree-days. Additionally, oyster larval abundance did not significantly vary between habitats but was significantly higher in the mid and near-surface part of the water column.

Summary: This study used a flat oyster SNP array to validate outlier loci associated with Bonamia ostreae in European flat oysters. The results showed that there were differences in genetic diversity and differentiation between outlier loci and neutral markers, with outlier loci mainly located on chromosome 8 of the flat oyster genome. Genes in this genomic region may be associated with resilience mechanisms to the parasite.

Summary: The study evaluated the potential of genomic selection for improving growth traits in European flat oyster populations. The heritability of growth traits was low to moderate, and a polygenic architecture was observed. Genomic prediction accuracies using low-density SNP panels were high.

Summary: This study investigated the genetic and environmental signals that regulate heading date in barley. The results showed that vernalization substantially affected plant traits and antioxidant enzyme activity. The expression of key regulatory flowering genes confirmed their involvement in heading time regulation. These findings contribute to a better understanding of the complex mechanism of barley heading date.

Summary: The annual production of European flat oysters in Croatia is about 50 to 65 tons and has a long tradition. A national surveillance program detected the presence of Bonamia spp. parasite since 2016, with no mortalities reported, calling for further molecular and epidemiological studies.

Summary: Oyster reefs have suffered the greatest losses among all marine ecosystems. Efforts have been made to restore these ecosystems, and a recent study focused on the genetic differentiation among oyster populations in Europe. The study detected genetic differentiation between Atlantic and Mediterranean populations, identified potential aquaculture-related translocations, and found a parallel pattern of differentiation between certain populations. This information will be useful for the selection of animals for translocation and restocking.

Summary: The European flat oyster (Ostrea edulis), an endangered and economically important species, has been found to possess a high-quality chromosome-level genome assembly. The genome contains a large number of protein-coding genes and repeat sequences, and shows evidence of population shaping by breeding habit and historical climatic change. The genome also exhibits unique features, such as a novel Hox gene cluster rearrangement, which makes it valuable for evolutionary studies. Additionally, the genome expansion of O. edulis contributes to its adaptation to various ecological factors. This chromosome-level assembly provides valuable insights and resources for genetic research, evolutionary studies, and conservation efforts of O. edulis.

Summary: This study collected infected flat oysters (Ostrea edulis) with the pathogenic parasite Bonamia ostreae in the Dutch Delta area and successfully selected individuals with Bonamia resistance to produce Bonamia-free larvae. The results showed that it is possible to screen for individuals with resistance to Bonamia during the hatchery production of flat oysters. Evaluation: 8 points.

Summary: The study found that European flat oysters performed well in pilot projects in the Dutch North Sea, demonstrating good growth and reproductive capabilities. Translocated oysters showed a strong growth rate and were able to adapt to their new environment. No Bonamia virus was found in the pilot projects, indicating that the Dutch North Sea is still Bonamia-free.

Summary: The study identified, cloned, and characterized two complete cDNAs of mdr1 and mdr2 genes in the mussel Mytilus galloprovincialis, demonstrating their possible involvement in detoxification processes of toxins. The results suggest that P-gp and MRP proteins may play a crucial role in defending against xenobiotics and resisting DSP toxins in aquatic organisms.
