Summary: European grayling is an endangered salmonid fish species with decreasing populations in European waters. This study analyzed the reproductive parameters of grayling females in a hatchery, including fecundity, egg size, and embryo survival. The results showed significant differences between first time spawners and repeat spawners, with repeat spawners producing more eggs. Absolute fecundity was correlated with the total length and weight of grayling females, while relative fecundity was not. Heavier eggs had a higher rate of survival, particularly for first time spawners. This suggests that larger and older grayling females should be prioritized for hatchery reproduction.

Summary: Genetic analysis of the GIFT strain of Nile tilapia in Fiji revealed mild declines in genetic diversity, with some ponds showing signs of reduced effective population size and allelic diversity. Management practices and potential wild interbreeding were identified as factors influencing genetic structure and relatedness within the broodstock nucleus. Regular genetic monitoring and evaluation of performance are recommended to preserve valuable genetic diversity in the long term.

Summary: The banded carpet shell Polititapes rhomboides in NW Spain exhibits high genetic diversity but some population differentiation. Mass spawning leads to reduced allelic richness and increased genetic differentiation in the seed produced. Effective number of breeders in the seed sample is significantly reduced, with a high inbreeding rate attributed to variance in reproductive success.

Summary: A family-based breeding program was established at the Aquaculture Genetics and Breeding Technology Center in 2004, focusing on the Eastern oyster. Genetic variations were abundant and additive, allowing for genetic gains to be captured from previous work. The program has found utility not only in the Chesapeake Bay but also along the mid-Atlantic coast, presenting a common approach for breeding efforts for C. virginica along the east coast of the US.

Summary: The study analyzed the genetic diversity of Rutana, Gumuz and Washera sheep populations in Ethiopia using whole genome sequence data. Genetic diversity indices such as observed heterozygosity, expected heterozygosity, inbreeding coefficient, and nucleotide diversity were calculated. The results showed moderate levels of genetic diversity among the sheep populations. Population structure analysis indicated that there was no clear separation between the populations, suggesting gene flow due to geographical proximity. The high rate of inbreeding in the sheep populations emphasizes the need for timely intervention to prevent inbreeding depression and extinction. The study also highlighted the importance of further research to identify genomic regions and biological pathways associated with important traits for selective breeding programs.

Summary: Inbreeding in Pacific oysters was found to have negative effects on growth and survival traits, leading to lower heritability in growth traits but no significant impact on survival rate heritability. This suggests that there is potential for selection in survival traits in inbred populations, which could be valuable for shellfish breeding programs.

Summary: This study assembled mitochondrial genomes of Crassostrea virginica from Texas using pooled restriction-site-associated DNA sequencing (ezRAD), and compared them with the published genome from Delaware. Genetic differentiation was observed between Delaware and Texas populations, but not among the three bays in Texas. The study highlights the utility of mitochondrial DNA for comparing historic data and emphasizes the importance of reliable mitochondrial genome assembly to facilitate cross-study comparisons.

Summary: This study investigated the genetic structure and diversity of the mangrove oyster in wild and cultivated populations in Brazil. Two main genetic groups were identified, one from cultivated populations and the other from wild populations along the southern and southeastern Brazilian coasts. Despite variability, the cultivated population showed relatively high genetic diversity values. Monitoring and establishing reference values for genetic diversity can aid in the viability of cultivated populations and the management of wild populations.

Summary: Successful stock enhancement programs aim to maintain economic profit while minimizing negative genetic and ecological effects. In the case of black rockfish, a stock enhancement program in the Liaodong peninsula showed positive economic performance with a resource contribution rate of 39.30%. However, potential genetic introgression from hatchery-reared individuals should be a concern. The hatchery-reared fish showed good adaptability, but exhibited some differences in size and morphology compared to wild individuals.

Summary: This study investigated the relationship between genetic variation and population dynamics in Boechera fecunda. The results showed a weak positive correlation between genetic diversity and demographic performance. The inbreeding coefficient was not strongly correlated with demographic performance. Conservation of distinct B. fecunda populations is recommended.

Summary: Genetic diversity is crucial for species survival during environmental changes, and understanding the distribution and amount of genetic diversity across multiple species is essential for conservation. Rare oak species generally have lower genetic diversity than common oaks, with small population size and geographic range possibly correlating with genetic diversity.

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.

It also enhances immune homeostasis and controls the growth of pathogenic bacteria.
