Summary: This study evaluated the performance and economic benefits of producing hybrid Catfish and Nile tilapia in Pond Raceway systems (IPRS). The results showed that this farming method can achieve efficient feed conversion rates and yield high gross production. The inclusion of Nile tilapia in the IPRS systems resulted in increased net returns and improved financial indicators.

Summary: This study evaluated the feasibility of genotype imputation from medium density to sequence level in Nile tilapia and investigated the impacts of size and origin of reference population in the accuracy of imputation. The results showed that using more animals from the same population as reference improved the accuracy of imputation, while using information from other populations had minor effect on imputation accuracy.

Summary: In this study on the 16th generation of Genetically Improved Farmed Tilapia, clear genotype-growth associations were found in both normoxic and hypoxic environments. MAPK and VEGF signaling pathways were identified as important components in hypoxic environment, especially during the later growth stage. A meta-analysis showed shared effects across both environments, with functional pathways playing different roles in nervous system development, organ growth, and oocyte maturation at different growth stages.

Summary: This study evaluated the performance and cold tolerance of different Nile tilapia stocks at suboptimal temperatures and identified alleles of microsatellite markers associated with cold tolerance. Among the tested stocks, S5 and S7 tilapias showed lower mean death temperature in cold tolerance assay, while stocks S3, S6, and S7 exhibited higher growth rates at suboptimal temperatures.

Summary: This study investigates the factors that structure methane's biogeochemistry in the Santa Barbara Basin. Seasonal oxygen loss and episodic replenishment are found to be major factors in structuring the accumulation of methane and the rate of methane consumption by microorganisms. The study also reveals low methane oxidation rates in summer, increased rates in fall during methane buildup, and elevated rates persisting into spring even after methane concentration declines. Furthermore, a mixing event during fall drives spatial and temporal variability in oxygen, nitrate, and methane concentrations in the basin.

Summary: The study utilized a multi-trait genome-wide association approach to identify quantitative trait loci (QTL) and genes associated with body traits in Nile tilapia. By combining summary statistics from single-trait genome-wide association studies, the study increased the statistical power for detecting genetic associations with body traits. The high-resolution mtGWAS allowed the detection of significant SNPs linked to functional candidate genes, providing further insights into genetic variants underlying body trait variation in cichlid fish.

Summary: Survival analysis was applied for the first time in aquaculture to analyze the relationship between morphometric traits and spawning time in Nile tilapia females. The study revealed that the standard length of the female, egg mass weight, and male weight affected the presence of eggs up to 28 days, and could be used as selection criteria for early breeders. The survival analysis proved to be an accurate tool for tilapia breeding management in an intensive system.

Summary: Genotype by environment interaction (G x E) is important in aquaculture species breeding, as selection in one environment may not have the same response in other environments. This study used a multiple trait reaction norm model to analyze the genetic relationship between growth traits of Nile tilapia in a (sub)tropical environment and found the presence of G x E. The genetic correlations may differ across different environments.

Summary: In this study, an evolutionarily conserved interleukin-22 (IL-22) was identified from Nile tilapia and found to be expressed in lymphoid-related tissues. IL-22 was shown to participate in the adaptive immune response by promoting lymphocyte proliferation and survival through the JAK1/STAT3 signaling pathway.

Summary: The study found that glyphosate and its mixture had direct and indirect effects on the survival of L. fortunei. In experiments with air supply, the accumulated mortality rates were 20.0% for glyphosate and 10.0% for the mixture. In experiments without air supply, L. fortunei intensified the changes in DO fluctuation patterns driven by the herbicides, leading to system hypoxia.

Summary: Blueberries comprise a diverse group of perennial species that have adapted to different climates and growing conditions through the introgression of native species. Phenotypic variance among blueberry accessions is influenced by genetic differences and variability in geographic and climatic conditions. The phenotype of blueberries is determined by a combination of genetic background, environment, and their interaction, as well as other factors such as year and harvest time. Certain blueberry cultivars show stable phenotypic characteristics across locations and years, with clonal plant replicates and individual fruit measures being significant sources of variability.

Summary: Human disturbance and climate change have a negative impact on habitat integrity and size, leading to population decline and habitat fragmentation for wild fauna and flora. Analysis of the genomic data of the pygmy hog reveals a very small historical population size with no recent inbreeding, but evidence of harmful mutation accumulation exceeding purifying selection. Care must be taken in conservation efforts to prevent further inbreeding depression and mitigate potential environmental changes.

Summary: The evolution of the placenta in live-bearing fish in the family Poeciliidae is associated with parallel changes in protein-coding genes and noncoding regulatory elements, particularly in transporter- and vesicle-located genes and developmental regulatory genes. The high occurrence of GATA simple repeats in regulatory elements suggests an important role in developmental gene regulation. This distinction in molecular evolution highlights the potential for changing regulatory pathways to allow for the evolution of complex traits in organisms.

Summary: European wildlife has been impacted by human activities, but genetic partitioning of many species still reflects the glacial refugia. By analyzing the genetic structure of wild boar across Europe, we found population fragmentation, inbreeding, and hybridization with domestic pigs at the local scale. However, a deep genetic structure indicating a natural continental division was still present. Our findings suggest weaker evidence for glacial refugia, but support the importance of Southern France and the Balkans as recolonization routes.

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.
