Summary: The study showed that the hybrid abalone Haliotis discus hannai female x H. fulgens male has a growth advantage over one of its parents due to differences in feeding behavior and digestive physiology. Changes in feeding-related genes in the nervous and digestive systems correlated with the initiation of abalone feeding behavior.

Summary: This study identified the LFRFa and short neuropeptide F receptor in Pacific abalone, demonstrating their key roles in food intake and reproduction. The expression levels of LFRFa are significantly higher in mature female abalone, and injection of LFRFa induces egg release and spawning behavior while suppressing food intake.

Summary: A water-soluble polysaccharide (AMPP) was successfully isolated from abalone muscle, with high carbohydrate content and a homogeneous structure. The structural characteristics of AMPP were elucidated using various analytical techniques. Additionally, AMPP exhibited potential immunostimulatory activity.

Summary: In this study, a natural deep eutectic solvent (NADES) was used to extract polysaccharides from abalone viscera. The optimal extraction conditions were determined using a design and response surface methodology, resulting in a maximum predicted polysaccharide yield of 17.32%. The polysaccharides extracted by NADES had higher sugar content, lower molecular weight, more glucuronic acid, and stronger antioxidant capacity compared to those prepared by the conventional method.

Summary: The study revealed that H. gigantea, H. discus discus, and H. discus hannai are susceptible to Abalone asfa-like virus (AbALV), while H. diversicolor is not. Through experimental infection and immunohistological observations, it confirmed that AbALV is the etiological agent of abalone amyotrophia.

Summary: The study demonstrated that CB and 6-DMAP concentrations and treatment durations significantly affected the triploid rate and hatching rate of abalone larvae. The optimal treatment combinations for triploid induction in autotriploid and allotriploid abalone were identified. This method using chemical treatments could be useful for increasing triploid strains in abalone aquaculture.

Summary: This study investigated the properties of abalone foot muscle proteins and their hydrolysates obtained using different enzymes. The results showed that these proteins and hydrolysates have good solubility, hydrolysis, oil holding capacity, emulsion stability, emulsifying activity, and foaming stability, making them suitable as a source of nutritive proteins in the food industry.

Summary: This study investigated methods to reduce the immunoreactivity of alpha-TM. It was found that glycation of alpha-TM with xylose significantly reduced its IgG/IgE-binding capacity. Additionally, five epitope peptides were found to bind with the site-specific IgE prepared by the glycated alpha-TM. Two glycation sites (M68 and N202/N203) were identified to affect the immunoreactivity of alpha-TM, suggesting that glycation could be used to develop hypo-allergenic abalone products.

Summary: A 105-day feeding trial was conducted to investigate the effects of dietary lipid and bile acids on the growth, digestion, and lipid metabolism in abalone. The results showed that 6.3% dietary lipid decreased the weight gain rate, while increasing dietary bile acids level enhanced the weight gain rate. The expression of genes involved in lipid transport, lipolysis, and lipogenesis was influenced by dietary lipid and bile acids. In conclusion, excessive dietary lipid content negatively impacted abalone growth, while appropriate levels of dietary bile acids significantly improved growth and digestion.

Summary: This paper proposes a multi-source information fusion approach combining passive acoustics with videos to analyze the sound production mechanism and acoustic characteristics of Haliotis discus hannai during feeding. The eating acoustic signals of abalone were mainly concentrated in a frequency range of 9.49 kHz to 44.36 kHz. The eating rate decreased significantly from 0.61 +/- 0.04 times/min to 0.48 +/- 0.08 times/min after 60 minutes. This study provides the first report on the characteristic analysis of abalone acoustic signals during feeding and demonstrates the sound production process of scraping and grinding food with radula.
