Get PDFNutrition composition of different size of male largemouth bass (<em>Micropterus salmoides</em>) and its implications for food processing industry
Get PDFTo understand the basic nutritional composition and enhance the application of largemouth bass (Micropterus salmoides), the nutritional quality of muscle and skin of largemouth bass with body weight of 450.10±1.11g, 650.31±1.20 g, and 850.10±1.13 g was analyzed. Results showed that the skin and muscle of fish with a body weight of 650.31±1.20 g were most suitable for processing and comprehensive utilization. Glycine had the lowest percentage, while glutamic acid was the most prevalent amino acid connected to umami. Total amino acid (TAA), essential amino acid (EAA), and D-aspartic acid (DAA) levels first increased and then decreased as the body weight increased. Largemouth bass of an intermediate size exhibited the highest levels of TAA and DAA, and superior amino acid balance and had the highest nutritional value among the three groups. The most common necessary minerals were Na, Mg, and K. The skin had higher concentrations of these elements than muscle, and their amounts rose and reduced in proportion to body weight. Our results demonstrated that the male largemouth bass with a body weight of 650.31±1.20 g had the muscle with the highest nutritional quality and the greatest application potential
Effects of PS-MPs on growth, immunity, antioxidant capacity and amino acid metabolism in common carp (<em>Cyprinus carpio</em>)
Get PDFTo explore the toxic effects of polystyrene microplastics (PS-MPs) on common carp (Cyprinus carpio), 0 µg/L, 50 µg/L, 100 µg/L, and 200 µg/L PS-MPs were designated as the control group (CK) and low, medium, and high concentration groups, respectively. Each group had 3 replicates and was exposed to PS-MPs for 15 days. The results showed that, compared with the control group, the weight gain rate and hepatopancreas somatic indices were significantly decreased in 100 and 200 μg/L PS-MPs groups, the visceral index was significantly decreased in 50 and 100 μg/L PS-MPs groups. In comparison to CK, experimental groups (50-200 µg/L PS-MPs) significantly decreased activity levels of acid phosphatase, alkaline phosphatase, and peroxidase while significantly increased activity levels of lysozyme, catalase, and superoxide dismutase. In addition, the malondialdehyde contents of the experimental carp increased significantly in 50 and 100 µg/L PS-MPs groups compared to CK. For hepatic amino acid contents, methionine, threonine, leucine, and isoleucine contents of the hepatopancreas of carp in PS-MPs groups were significantly lower than the control group. Correlation analysis showed that amino acids in the liver closely associated with fish growth, immune, and antioxidant-related indicators. In conclusion, PS-MPs above 50 µg/L in the water body could significantly affect normal growth, weaken the activity of hepatopancreatic immunity-related enzymes and antioxidant capacity, and disturb the balance of amino acid metabolism in common carp. The findings provide valuable insights into optimizing feeding strategies, contribute to more sustainable aquaculture practices, and support the development of policies in aquatic ecosystems
Impact of Acute Hypoxia Stress on the Antioxidant Capacity and Tissue Damage of <em>Penaeus monodon</em>
No full textThis experiment was conducted to examine the effects of acute hypoxia stress on Penaeus monodon, specifically focusing on its antioxidant capacity and tissue damage. The study aimed to understand how acute hypoxia stress influences these physiological parameters in P. monodon. Hepatopancreas and gill tissues were sampled at three distinct dissolved oxygen (DO) levels: a normoxic condition of 6 mg·L⁻¹, a hypoxic condition of 2 mg·L⁻¹, and an acute hypoxic condition of 1 mg·L⁻¹. Tissue collections were performed after exposure periods of 2 hours and 4 hours, respectively, to assess the effects of varying oxygen concentrations over time. The activities of immune enzymes (ACP, AKP) and antioxidant enzymes (T-AOC, T-SOD, MDA) were measured, and the hepatopancreas and gill tissues were examined through sectioning. The results showed that under hypoxic stress, the activity level of the experimental shrimp increased, the movement of the eye stalk was rapid, and the antennae and abdomen were significantly curved. AKP activity initially increased in response to stress but decreased over prolonged hypoxia exposure. ACP activity decreased with prolonged hypoxia but showed some recovery over time. T-AOC and MDA activities decreased with prolonged hypoxia exposure. T-SOD activity showed an increasing trend but decreased under excessive hypoxia. Different degrees of damage were observed in the hepatopancreas and gill tissues under hypoxia stress. The study indicates that hypoxia stress affects the activity of immune and antioxidant enzymes in P. monodon, causing tissue damage to the hepatopancreas and gills. These findings help elucidate the response mechanism of P. monodon to hypoxia stress and provide a reference for the healthy aquaculture of this species
Research on ecological-economic value equilibrium path of aquatic products from trust perspective
Get PDFEco-aquatic products have two important attributes: food safety and eco-friendliness. However, in China, the market price of most eco-aquatic products is not significantly different from that of ordinary aquatic products, which fails to fully realize their ecological value and high quality. This paper analyzed the path of realizing the ecological value and economic value of aquatic products from the perspective of trust. Through the analysis of three cases of Suzhou Haimei Family Farm, Suzhou Pinwei Aquatic Products Company, and Jiangsu Yunian Agriculture and Forestry Ecological Development Company, this paper showed how to improve consumer trust through community participation, social network and government endorsement, aimed at maximizing the value of ecological aquatic products. The case analysis demonstrates that adhering to the concept of ecological priority and sustainable development, building regional or product brand, maintaining brand image, and innovating diversified business strategies can effectively promote the development of aquaculture industry to a healthier and more environmentally friendly direction, and achieve a win-win situation of economic and ecological benefits
