AI Article Synopsis

  • The study focuses on Pacific abalone, a key mollusk in commerce, and aims to enhance its growth and quality through understanding lipid changes during its developmental stages.
  • Using advanced lipid profiling techniques, researchers identified 132 lipid types across various abalone developmental stages and 21 lipids in the hemolymph of mature abalones.
  • Key findings highlight triglycerides and phosphatidylcholines as major lipid components, while specific lipids like lysophosphatidylcholine were unique to mature abalone tissues, paving the way for improved abalone aquaculture practices.

Article Abstract

Pacific abalone () is a commercially important mollusk; therefore, improvement of its growth performance and quality has been emphasized. During embryonic development, abalones undergo a series of distinct larval stages, including swimming veliger larvae, juveniles, and mature individuals, and their biomolecular composition varies depending on the developmental stage. Therefore, in the present study, we performed untargeted lipid profiling of abalone tissues at different developmental stages as well as the hemolymph of mature female and male abalones using ultrahigh-performance liquid chromatography-tandem mass spectrometry. These profiles can provide meaningful information to understand compositional changes in lipids through abalone metamorphosis and development. A total of 132 lipids belonging to 15 classes were identified from abalone tissues at different developmental stages. Moreover, 21 lipids belonging to 8 classes were identified from the hemolymph of mature abalones. All data were processed following strict criteria to provide accurate information. Triglycerides and phosphatidylcholines were the major lipid components identified in both tissues and hemolymph, accounting for, respectively, 27% and 15% of all lipids in tissues and, respectively, 24% and 38% of all lipids in the hemolymph. Of note, lysophosphatidylcholine was only detected in the tissues of mature abalones, paving the way for further analyses of abalone lipids based on developmental stages. The present findings offer novel insights into the lipidome of abalone tissues and hemolymph at different developmental stages, building a foundation for improving the efficiency and quality of abalone aquaculture.
