Summary: This study evaluated the correlation between water changes and quality deterioration of Litopenaeus vannamei during partial freezing storage. The results showed significant increases in cross-sectional area and equivalent diameter, but irregular growth in roundness and longiness of the ice crystals. Bound water and immobilized water decreased significantly, while free water increased significantly during storage. Quality determination revealed a significant decrease in total sulfhydryl and Ca2+-ATPase, but a significant increase in disulfide bonds. Correlation analysis showed significant correlations between cross-sectional area and total sulfhydryl, Ca2+-ATPase, and disulfide bonds, respectively. Additionally, significant correlations were found between water distribution index and Ca2+-ATPase, disulfide bonds. Predictive models for ice crystal growth were developed based on cross-sectional area and equivalent diameter using the Arrhenius model.

Summary: The combination of citric acid and rosemary extract showed synergistic effects in inhibiting microorganism growth, lipid and protein oxidation, and maintaining sensory and texture profile of Pacific white shrimp during chilled storage. The treatment extended the shelf life of shrimp up to 8 days at 4±1°C. This combination has potential as a bio-preservative for shrimp.

Summary: This study evaluated the dietary requirement of niacin and its effects on the growth, feed utilization, immunity, and disease resistance of Pacific white shrimp. The results showed that increasing niacin levels in the diet improved the growth performance, feed utilization efficiency, and disease resistance of the shrimp. The optimum niacin requirement for Pacific white shrimp was estimated to be around 130 mg/kg diet.

Summary: A novel food processing technique combining cold atmospheric plasma (CAP) and chitosan oligosaccharide treatment (COS) was developed to enhance antibacterial performance and extend the shelf life of Pacific white shrimp. The synergistic effects of COS and CAP were found to inhibit the growth of microorganisms, with improvements in physicochemical properties and post-storage behaviors observed. Compared to the control group, the treated shrimp had a longer shelf life and inhibited the growth of the predominant microbial group. This study suggests that the combined use of COS and CAP is an effective technique for extending the shelf life of shrimp.

Summary: The study found that freeze-chilled storage can retard bacterial growth and the accumulation of putrescine in shrimp, but aggravate melanosis and lipid oxidation. The incorporation of tea polyphenol can preserve shrimp, alleviating melanosis and lipid oxidation.

Summary: This study aimed to determine the dietary riboflavin requirement and its effects on the growth performance, feed utilization, innate immunity, and diet digestibility of Litopenaeus vannamei. The results showed that riboflavin significantly improved the growth performance, non-specific immunity, and intestinal morphology of the shrimp, with an optimal riboflavin requirement of approximately 40.9 mg/kg diet.

Summary: Combining the carbon source and feed in one pellet in shrimp culture can improve shrimp performance, particularly when adding corn starch separately, leading to higher biomass gain and protein efficiency ratio. Carbohydrate addition resulted in a significant decrease in inorganic nitrogen and orthophosphate concentrations in water, while having no effect on biofloc and periphyton growth or the proximate composition of shrimp, biofloc, and periphyton.

Summary: This study examined the relationship between collagen degradation and changes in textural properties of Pacific white shrimp during 6-day storage at 4 degrees C. It was found that the texture of shrimp gradually decreased as muscle tissues were disrupted and that the chewiness of the muscle was linearly related to collagen contents. Collagen in shrimp muscle could be hydrolyzed by endogenous proteinases, with serine proteinase playing a critical role in the process. These findings suggest a close association between collagen degradation and the reduction in shrimp quality during cold storage.

Summary: This study investigated the effects of nanoplastics on Litopenaeus vannamei. The results showed that nanoplastics exposure activated the lysosome pathway and affected the PI3K-Akt signaling pathway. In addition, nanoplastics disrupted hepatic lipid metabolism, caused oxidative stress, and damaged tissue structure in L. vannamei.

Summary: This study investigated the impact of Vibrio alginolyticus on the intestinal histomorphology and microbiome composition in Litopenaeus vannamei. The results showed that Vibrio alginolyticus infection caused exfoliation of intestinal mucosal epithelial cells and altered the tissue morphology of the intestine. It also affected the abundance and diversity of intestinal microbiome.

Summary: This study describes a simple bioassay to estimate the relative attractability of feeds in Pacific white shrimp, Litopenaeus vannamei, by quantifying feed intake. Protein ingredients, especially squid meal and fish protein hydrolysate, significantly increased feed intake rates, indicating a potential for enhancing nutrient availability in shrimp diets.

Summary: In this study, the toxic effects of NOD on shrimp were investigated. Exposure to NOD resulted in significant histopathological damage, elevated oxidative stress, altered gene transcription, disturbed metabolism, and changes in intestinal microbiota. These findings provide valuable insights into the harmful effects of NOD on shrimp and identify potential biomarkers.

Summary: Creatine supplementation did not affect the growth performance or the content of guanidinoacetic acid in muscle and hepatopancreas, but significantly increased muscular creatine content. A specific level of creatine also significantly improved muscular hardness and chewiness by decreasing myofiber diameter and increasing myofiber density.

Summary: This study investigated the pharmacokinetics of eugenol in Pacific white shrimp through immersion baths in a simulated transportation. The results showed that eugenol was rapidly absorbed and eliminated in shrimp, with a tendency to accumulate in muscle. The hepatopancreas was identified as the main organ for the elimination of eugenol. Sequential administration resulted in higher concentrations of eugenol in hemolymph, hepatopancreas, and muscle, with faster elimination from the tissues. A withdrawal period was suggested based on the eugenol concentrations in shrimp muscle.
