Summary: In this study, the morphology and structure of the nerve ganglia of the scallop were investigated, and the ORF of GnRH gene was cloned and its expression patterns were studied. Tissue expression analysis revealed that GnRH was highly expressed in the parietovisceral ganglion. In situ hybridization further confirmed the distribution of GnRH mRNA in certain neurons in the posterior and lateral lobes. Additionally, higher expression of GnRH was found in female scallops during gonadal development, particularly at the growing stage in the parietovisceral ganglion. This study contributes to understanding the reproductive neuroendocrine regulation by GnRH in scallops.

Summary: Genetic improvement through image-based traits is crucial for meeting the increasing demand for high-quality, sustainably produced meat in the scallop industry. X-ray technology can provide non-invasive muscle imaging traits. This study showed that genetic breeding values based on image traits have the potential to enhance meat quality in Zhikong scallops.

Summary: The scallop Chlamys farreri is an important bivalve species cultured in northern China, but has suffered mass mortalities since 1996, likely caused by an intracellular Rickettsiales-like prokaryote (RLP). Through analysis of the 16S rDNA sequence, a novel prokaryote named Sinorickettsia chlamys sp.nov. was identified as the causative agent. Specific DNA probes were designed for detection, confirming the presence of the RLP in infected tissues of C. farreri.

Summary: This study genotyped six natural populations and artificially selected populations of Chlamys farreri and found high levels of genetic diversity in all populations. Artificially selected populations showed significant genetic differentiation from natural populations. Selective sweep analysis identified genes related to growth, reproduction, and stress resistance in the artificially selected populations. This study provides valuable information for resource management and germplasm improvement in C. farreri.

Summary: The changes in seawater temperature due to global warming have profound influences on the growth, survival, and production of aquatic species. This study focuses on improving the heat tolerance of Zhikong scallops through genomic selection. The study identified SNPs and genes associated with heat tolerance in scallops and demonstrated the potential of genomic prediction in breeding tolerant strains.

Summary: In this study, the researchers identified and characterized 17 TRP channels in the genome of the Zhikong scallop. These channels were found to participate in the early embryonic development and sensory processes of scallops, with C.FA TRPM3 and C.FA TRPC-alpha showing significant expression in the species. Additionally, under high temperature stress, specific TRP channels in scallops were upregulated, suggesting their role as thermoTRPs channels in scallops.

Summary: The study demonstrated that the addition of 4g/100g SPI combined with 0.4g/100g TGase significantly improved the gel properties of Zhikong scallop adductor muscle, enhancing gel strength and water holding capacity while optimizing textural profiles. The results also indicated that TGase facilitated protein cross-linking and network structure formation, mitigating the negative effects of excessive SPI.

Summary: Semicarbazide is considered a characteristic metabolite of nitrofurazone and is used as a marker for monitoring illegal nitrofurazone use in foods. Recent studies have shown that semicarbazide pollution can accumulate in aquatic organisms and threaten marine shellfish, ecological balance, and human health. The research found that scallops can uptake semicarbazide from seawater, potentially impacting the quality and safety of products used as food sources.

Summary: This study investigated the bioaccessibility and speciation of cadmium in scallops during gastrointestinal digestion and its implications for evaluation of biological effects and human safety. The results showed that steaming reduced the bioaccessibility of cadmium in different tissues of scallops. Based on the bioaccessible total cadmium and cadmium ions, the muscle, gonad, and mantle of steamed scallops were considered safe for human consumption according to the cadmium intake standards established by WHO and EFSA.
