Background/objectives: The Pacific abalone originated in cold waters and is an economically important aquaculture shellfish in China. Our goal was to clarify the current status of the genetic structure of Pacific abalone in China.
Methods: In this study, eighteen polymorphic EST-SSR loci were successfully developed based on the hemolymph transcriptome data of Pacific abalone, and thirteen highly polymorphic EST-SSR loci were selected for the genetic variation analysis of the six populations collected.

This study investigated microplastic pollution in the large mud snail Terebralia palustris (Linnaeus, 1767) (Gastropoda: Potamididae) inhabiting the Avicennia marina mangrove ecosystems along the Sea of Oman. A modified digestion protocol, combining two methods, was employed to improve the detection of microplastics within the snail tissue. Results indicated that 50 % of the examined snails contained microplastics, with significant variability observed among different lagoons.

Article Synopsis
- Awareness is growing about the threats to marine invertebrates like abalones, which are vulnerable due to slow growth and dense population needed for reproduction, compounded by fishing pressures and climate change.
- An IUCN Red List assessment revealed that 71.43% of commercially fished abalone species are classified as threatened, compared to only 15.15% of unexploited species, highlighting the severe impact of fishing practices.
- The North American Pacific coast shows the highest concentration of threatened abalone species, while areas like South Africa and Australia face issues with poaching and mass mortalities, prompting measures like ranching and stock enhancement to address these challenges.

In this study, we applied comparative transcriptomics and proteomics techniques to systematically investigate the dynamic expression patterns of genes and proteins at various stages of early embryonic development of the gastropod Neptunea arthritica cumingii. Twelve cyclin-dependent kinase (CDKs) genes and five downstream proteins associated with these CDKs were identified. Through techniques such as qRT-PCR, our data elucidate for the first time the regulatory functions of CDK family genes and establish CDKs as a pivotal gene cluster in the early embryonic development of N.
