Summary: This study reveals the involvement of exosomal protein SpFlotillin-1 in regulating immune responses during bacterial infection in mud crabs. Up-regulation of SpFlotillin-1 inhibits phagocytosis and reduces antimicrobial peptide expression, while increasing ROS production. Moreover, SpFlotillin-1 densely packaged in exosomes modulates phagocytosis, AMP expression, and ROS production through the MAPK and NF-kappa B pathways, ultimately activating the immune response to bacterial infection in mud crabs.

Summary: The state of California is re-evaluating its policies and practices towards sustainable aquaculture. Interest groups and community members in California generally show a positive sentiment towards expanding seaweed and bivalve production locally and promoting local consumption, while expressing a strong preference against relying on foreign imports.

Summary: This study reveals the crucial role of Snail2 alpha and Snail2 beta in the immune response of crayfish against White spot syndrome virus (WSSV). The research shows that WSSV induces the transcription of immediate-early genes ie1 and ie15 through the nuclear translocation of Snail2 alpha and Snail2 beta. However, crayfish responds to WSSV escape by reducing the expression of these two proteins.

Summary: Cage-based mariculture ventures in India, particularly focused on Asian seabass, are expanding. However, there is a lack of comprehensive techno-economic assessment hindering the sector's growth potential. To address this, a decision-support model was developed to optimize investment decisions and forecast economic performance. Capacity utilization and the adaptability of the Asian seabass were found to be critical for the success of the enterprise.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.

Summary: We developed a miRNA biosensor for early detection of viral infections in fish farms, specifically for VHSV infection. The biosensor showed a wide linear response range and low detection limit, providing an effective tool for monitoring and preventing the spread of infections in aquaculture.

Summary: This study established a granuloma model in the spleen of largemouth bass infected by Nocardia seriolae, and investigated the histopathological characteristics and formation mechanism of splenic granulomas. The study found that necroptosis is closely related to the formation of splenic granulomas in largemouth bass.

Summary: Using transcriptomics and metabolomics, this study revealed the impact of nitrite on largemouth bass and its underlying molecular mechanisms. The exposure to nitrite was found to cause damage to the spleen, heart, and gills, while potentially leading to hepatic pathologies. The spleen was the most vulnerable organ, experiencing acute and reversible damage. Nitrite altered gene expressions, triggered apoptosis and autophagy, and affected metabolic pathways. The study also identified pivotal genes and functional pathways related to nitrite exposure and provided insights for improving aquaculture practices.

Summary: This study investigated the species composition and spatial distribution of bryozoan diversity in the southern region of Franz Josef Land. A total of 151 bryozoan species were found, including 22 species recorded for the first time in this region. The diversity of bryozoans in this area is influenced by environmental factors such as depth, temperature, and the content of stones and shells.

Summary: Sea level and bottom water temperature variations caused by the Last Deglaciation climate warming have impacted the stability of marine hydrates. Simulations revealed that hydrate dissociation occurred in certain areas of the northern South China Sea, resulting in the release of methane into the seawater and atmosphere. The depth at which dissociation occurred ranged from 480 to 720 meters, covering approximately 6.68% of the northern South China Sea Area. Since the Last Deglaciation, an estimated amount of hydrates dissociated, releasing a significant amount of methane.

Summary: In this study, the performance of the hidden Markov models (HMMs) for detecting and classifying whale vocalisations was improved. Feature extraction techniques based on principal component analysis (PCA) were proposed to extract relevant features. The experiments using PCA-HMMs and kPCA-HMMs on southern right whale and humpback whale vocalisation datasets showed that kPCA-HMMs outperformed PCA-HMMs. The proposed PC-HMMs not only outperformed existing FE-HMMs but also had lower computational complexity.
