The essential role of mTOR in promoting feeding behavior through regulating NPY and AgRP expression in mandarin fish (Siniperca chuatsi) larvae

The success of initial feeding during the mouth-opening stage is crucial for the survival and growth of fish larvae. Carnivorous mandarin fish (Siniperca chuatsi) face unique challenges in capturing...

Genome-wide identification, expression analysis of toll-like receptors (TLRs) in black carp (Mylopharyngodon piceus), and the positive role of MpTLR1 against Aeromonas hydrophila infection

As one of the world's “staple” freshwater fish species, black carp (Mylopharyngodon piceus) faces critical challenges from bacterial diseases. Toll-like receptors (TLRs), serving as frontline pathogen...

Advancing aquaculture breeding through genomic selection: models, tools, and challenges

Genomic selection (GS) is a powerful breeding tool that utilizes statistical models to predict breeding values for candidate populations by leveraging genotype–phenotype relationships. In contrast to...

Invasive species and trophic pathways: long-term shifts in food chain dynamics of a fragmented river's floodplain

Impoundments within the Paraná River basin have significantly impacted the Upper Paraná River Floodplain (UPRF). The Itaipu Hydropower Plant, installed in 1982, removed a natural barrier, enabling fish...

Hydraulic factors influencing tropical fish movement in hydropower plant tailraces

Hydroelectricity is a significant source of electricity in many countries around the world. Blockage of fish migration routes is an environmental impact caused by hydroelectric power plants and schools...

The mycolic acids of Nocardia seriolae hijack Coronin-1A to inhibit autophagy for macrophage-derived foam cell formation

Nocardia seriolae alters macrophages to a “foamy” phenotype characterized by the accumulation of lipid droplets during infection to create a habitat that is ideally suited to its requirements. However,...

The role of ecohydraulics in addressing the freshwater biodiversity crisis

Ecohydraulics is a scholarly discipline and community of practice that represents the intersection of ecology and hydraulics/fluid dynamics. Although understanding the intersection of ecology and hydraulics...

Fish LASP1 promotes NBR1-mediated MAVS autophagic degradation to inhibit IFN production

The mitochondrial antiviral signaling protein (MAVS) plays a pivotal role in the interferon (IFN) activation signaling pathway, which culminates in the production of IFN and the establishment of a positive...

Dietary nano iron enhanced the intestinal physical barrier, antioxidant capacity and immune function of juvenile largemouth bass (Micropterus salmoides)

Nano-additives can improve the absorption and utilization of feed nutrients. In this study, we reported the effects of supplementary nano iron (0, 30, 60, 120, 240 and 480 ​mg/kg) on intestinal tract...

Commercial product-derived microplastics based on polypropylene and polylactic acid and their harmful effects on the sea urchin Paracentrotus lividus (Lmk) embryos: Morphological and gene expression analysis

Plastics provide a range of benefits in our society, even if waste plastics are representing a worrying issue for the environment. In addition, various additives, i.e., chemical substances added to...

Ichthyofauna of the Paraopeba river: Richness, endemism, and conservation of a highly impacted basin

The Paraopeba River, one of the largest tributaries of the São Francisco River basin, extends approximately 500 ​km and drains a densely populated region in Minas Gerais, Brazil. The aquatic ecosystems...

Single nucleotide polymorphisms reveal the population genetics and evolutionary history of the Asian swamp eel across Asia

The Asian swamp eel (putatively Monopterus albus) is recognized as one of the most economically significant specialty freshwater fishes in China. Nonetheless, there is a lack of systematic research...

Single-cell transcriptomics unveils cellular adaptations to high-salinity stress in kidneys of GIFT tilapia

Fish osmoregulation was characterized by modifications in both the structure and functionality of numerous osmoregulatory cells and organs. Single-cell resolution investigations are imperative for comprehending...

Invasive mosquitofish (Gambusia holbrooki) have longer gill telomeres in polluted and mesohaline habitats

Chemical pollution is a widespread stressor for wild organisms, but its effects on molecular damage and aging are still poorly understood. Telomere attrition has been used as an integrative biomarker...

Evaluation of aquatic plant community diversity in an urban eutrophic lake—a combination of traditional survey and metabarcoding methods in Donghu Lake, Wuhan

Aquatic vegetation plays a crucial role in wetland ecosystems but are sensitive to human activities, especially in urban lakes where the loss of aquatic plant diversity is pronounced. Recently, there...

Spatiotemporal dynamics and interrelationships of fish assemblages and environment under stocking-based ecological fisheries practices: Insights from Qiandao Lake

Qiandao Lake, a key drinking water reservoir and a national model for Stocking-based Ecological Fisheries (SEF) in China, has been intensively managed to balance fishery productivity with ecological...

Fish carcass dynamics in a tropical river: insights for assessing damage in fish mortality events

The absence of knowledge about carcass dynamics in fish mortality events hampers their detection, the quantification of biomass or number of dead fish, and accountability of the responsible agent. This...

Conservation biogeography of the freshwater blenny (Salariopsis fluviatilis): Exploring an unusual distribution

The freshwater blenny Salariopsis fluviatilis is fairly widespread across Mediterranean inland freshwaters but with an unusually patchy distribution. We investigated the species’ distribution patterns...

Aquatic pollution from truck spills: Urgent action needed in Brazil and beyond

On 29 January 2024, a truck accident spilled concentrated sulfonic acid into a river in Brazil's State of Santa Catarina. This disaster, which occurred in a protected area, killed various types of fish...

Confronting the “knowledge-action gap” in invasive species prevention: A study of biosecurity behaviors among aquarium hobbyists in Illinois, USA

Biological invasions threaten water resources worldwide owing to interrelated biological and anthropogenic drivers of change. Though the role of people in the (un)intentional spread of aquatic invasive...

Neuroprotective Kunitz-like peptides identified from the octopus coral Galaxea fascicularis through transcriptomic analysis

Parkinson's disease (PD) is the second most common neurodegenerative disease. Potassium voltage-gated channels are potential targets for the treatment of PD. The aim of this study is to identify novel...

An updated range-wide assessment of Neophocaena: Threats and priorities for research and conservation

The genus Neophocaena includes two species, the Indo-Pacific finless porpoise (N. phocaenoides) and the Narrow-ridged finless porpoise (N. asiaeorientalis). The Indo-Pacific species is found in coastal...

Key environmental factors determining life history strategies of river fishes and their historical changes in the Yangtze River

Life history theory predicts that species-specific life history traits are shaped by variations in environmental conditions. Understanding the key environmental factors determining life history strategies...
