Summary: Baker & Sheaves criticize the Whitfield review for suggesting high predation pressure on juvenile fish in shallow estuarine nursery habitats, while research in South Africa supports the idea that shallow littoral areas provide refuge for small juveniles. More targeted research is needed to confirm the role of littoral estuarine waters as a universal keystone attribute.

Summary: This study examined the accumulation of microplastics (MPs) in the guts and gills of 11 fish species from Lake Chao in China, revealing selective accumulation of MPs in fish guts and random accumulation in fish gills. The results also showed that fish guts exhibited distinct foraging preferences for specific featured MPs, suggesting that fish guts could be used as a sensitive organ for monitoring the ecological risk of MPs on fish health. Fish gills, on the other hand, were found to be more related to real-time MPs abundance in water and could be employed as important instruments to reflect MPs contamination in aquatic environments.

Summary: A parallel-cell triboelectric nanogenerator (PC-TENG) is proposed in this study, which outperforms the serially connected zigzag structure-based triboelectric nanogenerator (Z-TENG) in terms of power output and has a higher power density. The frequency and reciprocating distance of the excitation are found to positively affect the output of the PC-TENG.

Summary: The study demonstrated differential effects of PCB153 and PCB126 on Cyp3a56 mRNA expression in gills and liver of Atlantic killifish from contaminated and reference sites, indicating a potential heritable resistance to non-dioxin-like PCBs. Induction of Cyp3a56 in the gills may serve as a biomarker for exposure to non-dioxin-like PCBs in fish populations.

Summary: The study found that exposure to silver nanoparticles can significantly alter 96 metabolites in fish gills, primarily affecting amino acid metabolism and energy metabolism. Silver nanoparticles specifically induce changes in 72 metabolites, enriching pathways such as aminoacyl-tRNA biosynthesis, ABC transporters, and the citrate cycle. On the other hand, exposure to silver supernatant ions causes specific changes in 14 metabolites, mainly interfering with sphingolipid metabolism in fish gills.

Summary: This study assessed the relationship between the abundance of introduced fish species and the body condition of an endangered species, the Colorado pikeminnow, in the upper Colorado River. The results showed a positive correlation between the body condition of the pikeminnow and the densities of two common non-native cyprinid species. However, no such correlation was found with a third species.

Summary: This study investigated the gene expression profiles and alternative splicing events in the spotted sea bass fish under hypoxia stress. The results revealed the activation of the HIF signal network system and the suppression of the cell cycle process in response to hypoxia. Additionally, key biological pathways and alternative splicing events associated with hypoxia were identified. These findings contribute to a better understanding of the molecular mechanisms of hypoxia response in spotted sea bass and other fish species.

Summary: This study investigated the acute toxicity, behavioral and histological effects of trichlorfon on arapaima larvae. The results showed that trichlorfon concentrations of <= 250 mg/L and short exposure times (up to 180 min) can be safely used in arapaima larvae without adverse effects.

Summary: The study found that the diet composition of brown bullhead is highly varied and depends on its body size, with fish making up a significant proportion of the diet as the fish grows in size. The nature of the habitat may influence the diet composition of brown bullhead, especially evident in individuals with a total length less than 135 mm.

Summary: This study investigated whether fish are capable of exhibiting complex behaviors, specifically play. By exploring the responses of different fish species to laser pointer stimuli, the researchers found that over 80% of the fish displayed an inquisitive response, with a particular interest in red laser spots. The study also reviewed existing literature on fish play and discussed whether the observed fish responses could be considered as play behavior.

Summary: Microplastic pollution has become a major global concern, with high incidences found in commercial fish in coastal areas of Guangdong, China. The study analyzed the abundance, type, shape, and color of microplastics in gills and the gastrointestinal tract of eight species of commercial fish in central and western Guangdong. The results showed that carnivorous fish had lower microplastic ingestion in their gastrointestinal tract compared to herbivores or omnivores, while middle-water fish were less likely to have gill contamination with microplastics.

Summary: Air-breathing in fish is an evolutionary adaptation to aquatic hypoxia. Little is known about the air-breathing behavior of the African bonytongue fish, Heterotis niloticus. In this study, we found that the air-breathing behavior of H. niloticus fingerlings is highly influenced by abiotic factors and physical activity.

Summary: This study found that PI3K gamma regulates the dephosphorylation of β1 and β2 adrenergic receptors by inhibiting PP2A, which in turn affects cardiac function and remodeling, and the activation of PI3K gamma is associated with hypoxia sensing. In mice with PI3K gamma knockout, the phosphorylation of β1 and β2 adrenergic receptors is reduced and cardiac function is improved after hypoxia.
