Summary: A 60-day feeding trial was conducted to determine the optimum phosphorus requirement for juvenile bighead carp. It was found that supplementing the diets with phosphorus improved weight gain, specific growth rate, and feed conversion rate. Moreover, the phosphorus content and lipase activity in the fish's body also increased with dietary phosphorus levels.

Summary: Bone hydrolysates from bighead carp prepared with Protamex exhibited strong antioxidant activity, effectively delaying protein and lipid oxidation. Impregnating carp fillets with these hydrolysates improved sulfhydryl content, Ca2+-ATPase activity, and reduced carbonyls and TBARS levels. Overall, Protamex-derived fish bone hydrolysates have potential as antioxidants for fish fillet preservation.

Summary: The addition of NaCl is closely related to the oxidation of meat, and mitochondria play a key role in the oxidation process of proteins. This study found that increasing concentrations of NaCl caused higher levels of oxidation in bighead carp fillets by affecting mitochondrial membrane potential and enzyme activity. Notably, 2.0 M NaCl was found to promote lipid or protein oxidation by disrupting mitochondrial membrane structure and influencing peroxisome activity.

Summary: This study evaluated the biophysical characteristics of faeces from channel catfish and bighead carp at different temperatures and examined their environmental impacts. The results showed that an increase in water temperature accelerated the settling velocities of the faeces. The nutrient contents in channel catfish faeces were higher than those in bighead carp faeces. Co-culturing these two fish species can effectively reduce nutrient discharge in aquaculture.

Summary: This study reported the molecular cloning and characterization of HIF-1 alpha in bighead carp, revealing a high conservation of the protein with its structure being extremely similar to that of mice. The mRNA levels of anHIF-1 alpha in bighead carp tissues were significantly upregulated under decreasing oxygen concentrations, indicating an important stress response adaptation to hypoxia. Further comparative analyses between anHIF-1 alpha and mouse HIF-1 alpha suggest potential for comparing the physiological function and protein structure of HIF-1 alpha between fish and mammals in the future.

Summary: In this study, polysaccharide-based nanoparticles were developed using chitosan and flaxseed gum through polyelectrolyte complexation. These nanoparticles served as carriers for the delivery of bighead carp peptide (BCP). The optimal conditions for nanoparticle preparation were a chitosan molecular weight of 50 kDa, a chitosan/flaxseed gum mass ratio of 1:2 at pH 3.5, resulting in the smallest particle size (approximately 155.1 nm) and the highest BCP encapsulation efficiency (60.3%). The BCP-loaded nanoparticles exhibited controlled release and dose-dependency, making them a promising carrier for bioactive peptide delivery.

Summary: Dipping frozen bighead carp fillets in tea polyphenols (TPs) effectively inhibited the formation of biogenic amines (BAs) and loss of free amino acids (FAAs) during frozen storage, leading to lower levels of BAs and improved pH and TVB-N values in the treated samples. Redundancy analysis (RDA) revealed positive correlations between certain amino acids and amines, while negative correlations were found between other BAs and their precursor FAAs.

Summary: ACE inhibitory peptides were identified from bighead carp protein and were conjugated with graphene oxide (GO) to enhance their activity. Among these peptides, YLRLHF showed the best ACE inhibitory activity and was a competitive inhibitor. Molecular docking experiments showed that YLRLHF formed hydrogen bond interactions, coordination bonding with Zn2+, and conjugation interactions to His421 in the ACE protein pocket. GO elevated the ACE inhibitory activity of YLRLHF. The successful combination of GO and YLRLHF was confirmed by structural characterization results. These ACE inhibitory peptides from bighead carp proteins with GO have potential applications in functional foods and antihypertensive drugs.

The results showed that spray-drying increased the antioxidant activity and ferrous iron chelating activity of the hydrolysate, while the drying method had little influence on the ABTS radical scavenging activity and ACE inhibitory activity. Additionally, the drying method affected the physicochemical properties and structural characteristics of the hydrolysate.

Summary: This study used network analysis to investigate the seasonal stability of microbial communities in lake ecosystems. The results showed distinct differences in microbial networks among seasons, with the most complex network in autumn exhibiting the highest stability. Water temperature and pH were found to be significantly correlated with strong connecting structures among microbes, which impacted keystone taxa and destabilized microbial communities. Additionally, the presence of keystone taxa contributed to the stability of the networks, and their removal resulted in unstable networks. The specific composition of keystone taxa in different seasons was influenced by environmental filtering and interspecific interactions. These findings highlight the influence of seasonal variations in environmental factors on microbial networks and community stability.

Summary: This study proposes a method to assess the net carbon sink of marine macroalgae (Gracilaria) cultivation and predicts its future trends. The findings show that the net carbon sink of Gracilaria cultivation in China was about 32.1-92.4 kilotons per year from 2011 to 2020 and exhibits a significant annual growth trend. The predicted net carbon sink of Gracilaria cultivation is expected to increase to 77.8-191.4 kilotons per year from 2021 to 2030, which could contribute significantly to China's carbon peak goal. Furthermore, using Gracilaria for ruminant green feed production is predicted to reduce carbon emissions (methane) by 0.33-0.68 tons per ton of macroalgae.

Summary: Biodiversity is crucial for ecosystem functions and services. While there have been many studies on biodiversity-ecosystem functioning (BEF) relationships in plant and animal systems, it remains unclear if such a relationship exists and how it evolves in microbial systems. In this study, synthetic denitrifying communities (SDCs) were constructed using 12 Shewanella denitrifiers with varying species richness. The results showed a positive correlation between community richness and functions, but this correlation was only significant in earlier stages of the evolution experiment. Additionally, community functions generally increased throughout the experiment, with lower richness communities showing greater increases and positive BEF relationships largely attributable to complementary effects.

Summary: Microeukaryotes and bacteria play important roles in aquaculture ecosystems. This study examined their co-occurrence relationships using high-throughput sequencing data. The networks showed dominant phyla of Chlorophyta and fungi in water and sediment, respectively. Most microeukaryotes and bacteria were classified as generalists and had symmetric connections. Some microeukaryotes had asymmetric connections in water. Four microeukaryotes and twelve uncultured bacteria were identified as potential keystone taxa. The microeukaryotic-bacterial bipartite network in sediment had more nestedness compared to water. Loss of microeukaryotes and generalists could lead to the collapse of positive co-occurrence relationships in both water and sediment. This study provides insights into the structure and function of microeukaryotic-bacterial networks in aquaculture ecosystems.
