Summary: Low salinity negatively affects growth and survival in the eastern oyster, which decreases aquaculture productivity. With increased heavy rainfall events, coastal aquaculture operations face higher risk of prolonged exposure to extreme low salinity conditions. Experimental challenges investigate the importance of challenge duration and temperature on survival phenotype and genetic parameters.

Summary: This study examined the impact of oyster aquaculture on the benthic community of Delaware Inland Bays and found no significant effects on polychaetes abundance and richness. Little Assawoman Bay had significantly higher polychaetes numbers and species richness compared to other bays. A bloom of Ulva lactuca in 2016 may have negatively impacted the polychaetes community.

Summary: Tidal impoundments, specifically lobster pounds, have the potential to bridge the gap between the fishing and aquaculture industries. Lobster pounds are uniquely positioned to overcome barriers to aquaculture entry and provide suitable spaces for oyster growth, as shown by the successful growth of oysters within the study pound.

Summary: This study investigated the impact of intermittent heat stress on the mitochondrial functions of the eastern oyster, revealing that oysters acclimated to 22.5 degrees C struggled more with heat shocks. However, both acclimated populations showed signs of potential recovery after the second heat shock.

Summary: The salinity conditions in oyster breeding grounds in the Gulf of Mexico are expected to change drastically due to climate change and human-induced alterations in local hydrology. This study investigated the adaptive capacity of eastern oysters to low salinity through genetic variation and transgenerational plasticity. The results suggest that genetic variation, with a heritability estimated at 0.68 +/- 0.25, plays a key role in evolving traits for future salinity changes.

Summary: The Eastern Oyster Breeding Consortium has developed two SNP arrays for the eastern oyster, enabling efficient genotyping and selection. These arrays provide easy identification and separation of selected stocks and can also be used for pedigree monitoring, assessment of oyster restoration success, and genetic improvement. The arrays will advance genomic research and accelerate the breeding of eastern oysters.

Summary: This study quantifies the ability of Eastern oysters to excrete microplastics in their biodeposits, finding that oysters of all sizes can excrete environmental microplastics, with smaller oysters being more efficient. These findings are important for resource managers and contribute to our understanding of microplastic accumulation in wild oyster populations, as well as their implications for oyster consumers.

Summary: The study focused on the establishment of a sperm repository for the Eastern oyster Crassostrea virginica to support breeding programs in the Gulf of Mexico. Fresh sperm samples were collected from wild populations along the U.S. Gulf of Mexico coast and cryopreserved for future use. The streamlined process demonstrated in the study can serve as a template for constructing similar oyster germplasm repositories.

Summary: The study investigated the effects of environmental conditions and oyster phenotypes on the composition and diversity of oyster larval microbiomes. It found significant differences between larval and water microbiomes, with hatchery and spawning having the most impact on microbiome composition. Despite no significant effect on microbiomes, larval developmental stages showed a decrease in species richness and a shift towards a more selective microbiome.

Summary: A high-density SNP array (200K) was developed for the Eastern oyster (Crassostrea virginica) using low-coverage whole-genome sequencing. The array was validated and found to be a necessary tool for genomic approaches, including genomic selection, in C. virginica selective breeding programs.

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.
