Summary: This study investigated the epigenetic mechanism of phenotypic plasticity in marine invertebrates using Pacific oysters, revealing divergent methylation patterns between intertidal and subtidal oysters with different responses to high temperatures. The results suggest that DNA methylation mediates phenotypic divergence in oysters adapting to different environments, providing new insights into the epigenetic mechanisms underlying phenotypic plasticity in marine organisms adapting to rapid climate change.

Summary: Oxidative stress was observed in Pacific oysters (Crassostrea gigas) exposed to high temperature both in indoor experiments and during outdoor aquaculture period. The oxidative stress indicators (SOD, CAT, POD, T-AOC, MDA, and GSH) showed significant changes, with a decrease observed at 28°C in the high-temperature treated groups. During the outdoor aquaculture period, MDA content decreased significantly with increasing temperature. Overall, these findings provide valuable insights into oxidative stress in Pacific oysters exposed to high temperature.

Summary: Early exposure to an environmentally relevant pesticide mixture induces multi-scale latent effects possibly affecting life history traits in the Pacific oyster, Crassostrea gigas. The study found that exposure to a combination of 18 pesticides and metals at environmental concentrations during the embryo-larval stage resulted in disturbed swimming behavior, increased size and weight at specific time points, and altered expression of development-related genes. Additionally, DNA methylation analyses showed significant modifications in exposed larvae, marked by a demethylation trend.

Summary: The study evaluated the impact of larval stocking density on larval yield, competent larvae, and larval shell length of Crassostrea gigas in a recirculation aquaculture system (RAS). Results indicated that the optimal densities for larval rearing were 50 and 75 larvae mL-1, leading to the best growth and highest proportion of competent larvae. This RAS approach could enhance resource efficiency and profitability for commercial hatcheries.

Summary: This study investigates the IgE sensitisation profiles of patients with oyster allergy to raw and heated Pacific oyster extract. Tropomyosin is identified as the major allergen responsible for oyster allergy, and the study also reveals partial cross-reactivity and/or co-sensitisation between oyster, prawn, and dust mite allergens. This research emphasizes the importance of using recombinant tropomyosin in improved diagnostics and immunotherapy.

Summary: This study identified 66 TRP genes in Pacific oyster with significant gene expansion and tandem duplication. The analysis of RNA-Seq data after acute heat stress revealed a set of heat-inducible TRPs. Further study under chronic heat stress and comparison between two oyster species led to the identification of TRPC3.6, TRPC3.7, and TRPV4.7 as important TRPs involved in thermal regulation in oysters.

Summary: This study investigates the effect of all-trans retinoic acid (ATRA) on the transcriptome of the Pacific oyster Crassostera gigas. A total of 586 differentially expressed genes (DEGs) were identified, with ATRA affecting the development, metabolism, reproduction, and immunity of C. gigas. Several tyrosinase genes and Tyr-related genes were upregulated by ATRA, and the DNA-binding activity of the RA receptors CgRAR and CgRXR, as well as their interaction with RAREs in the Tyr-2 promoter, were confirmed.

Summary: This study investigated the effects of temperature on the bioaccumulation and depuration processes of Crassostrea gigas exposed to Cd, as well as its molecular responses. The results showed that the concentration of Cd in different tissues varied at different temperatures, and both uptake rate and elimination rate were influenced by temperature. Additionally, the expression of metallothionein and P-glycoprotein also showed temperature-dependent changes.

Summary: Many marine invertebrate phyla undergo indirect development, transitioning from planktonic larvae to benthic spats through settlement and metamorphosis. Understanding the molecular regulation dynamics during metamorphosis is crucial for understanding the origin and evolution of indirect development. This study examined the gene expression patterns and open chromatin region changes during metamorphosis using metamorphosis-competent pediveligers of the Pacific oyster. The findings revealed significant differences in gene regulation networks before, during, and after metamorphosis, suggesting the involvement of various genes and molecular processes in oyster metamorphosis.

Summary: The study reveals that Pacific oysters have a certain sensitivity to paralytic shellfish toxins, with a micromolar range of sensitivity to saxitoxin but less sensitivity to tetrodotoxin. Oysters can be categorized into STX-resistant and STX-sensitive groups regardless of the diet they consume. Additionally, the study highlights the potential of cerebrovisceral nerves of Pacific oysters for electrophysiological and pharmacological studies and demonstrates that the STX sensitivity of oyster nerves can decrease upon exposure to dinoflagellates.

Summary: The Yaqui catfish, a native ictalurid species in Mexico and the USA, is endangered due to competition and hybridization with non-native channel catfish. Research found evidence of hybridization between Yaqui catfish and channel catfish in a remnant population, highlighting it as a major threat. Urgent evaluation of remnant populations and conservation status of native catfish is recommended.

Summary: The study highlights the global introduction and establishment of Pacific oysters for aquaculture, with varying impacts on local ecosystems and economies. Economic factors such as GDP per capita and geographic location play a significant role in the introduction and establishment of oysters, while commercial production is influenced by coastline length and established populations. Efforts to study and mitigate the impacts of feral oyster populations are ongoing in several countries, with implications for coastal management worldwide.

Summary: Microplastics in marine ecosystems serve as microhabitats for diverse toxic plankton species, including viable resting cysts of dinoflagellates. The diversity of plankton communities on the plastisphere is influenced by anthropogenic factors. This study highlights the importance of plastics as vectors for the transport of harmful opportunistic species in the marine environment.

Summary: The Barents Sea, as the largest Arctic shelf region, plays a vital role in supporting commercial fisheries. The ecosystem of this region is significantly influenced by both warm Atlantic Water (AW) and cold Arctic Water (ARW), resulting in distinct frontal zones. This study found that copepod populations, particularly herbivorous copepods, were most abundant and productive in the Polar Front, as well as in the eastern frontal zones. The geographic positions of sampling stations, depth, and chlorophyll a concentration were identified as the main factors influencing copepod biomass and production.
