Cyanobacterial harmful algal blooms (cHABs) are pervasive sources of stress resulting in neurotoxicity fish. A member the widely distributed Microcystis genus bloom-forming cyanobacteria, wesenbergii can be found many freshwater lakes, including Dianchi Lake (China), where it has become one dominant contributors to lake's recurrent blooms. However, unlike its more well-known counterpart M. aeruginosa, effects dense non-microcystin-containing seldom studied. The disturbance appetite regulation and feeding behaviour have downstream on growth teleost fish, posing a significant challenge aquaculture conservation efforts. Here we examined food intake Acrossocheilus yunnanensis, native cyprinid southern China. This fish species disappeared Lake, reintroduction might negatively affected by presence this newly-dominant species. We co-cultured juvenile A. yunnanensis with non-microcystin-producing strain at initial densities between 5 × 104 1 106 cells/mL monitored changes neurotransmitter hormone protein levels. High-density cultures increased rate elevating concentrations appetite-stimulating signalling molecules (Agouti-related γ-aminobutyric acid), while decreasing inhibitory ones (POMC). These coincided histopathological alterations reduced somatic indices brain intestinal tissues. Given potential for detrimental dysregulation intake, further studies necessary determine impacts chronic exposure wild

The escalating issue of water pollution, especially the accumulation organic off-flavor pollutants, poses significant challenges. Geosmin, a typical compound in aquatic environments, not only compromises quality products but also deters consumers. Its impact extends to organisms, with current research focusing on dose-response and ecotoxicity, while neglecting molecular-level study geosmin-binding proteins. This employs an integrated approach combing affinity-responsive target stability vitro, tandem mass tag proteomics vivo, molecular docking identify proteins gill tissue grass carp (Ctenopharyngodon idella). ARTS analysis identified 56 proteins, predominantly membrane-associated such as catenin beta-1, annexin, integrin beta. Proteomic revealed 256 differentially expressed geosmin-exposure group, 18 common screened by vivo vitro methods. Among these, cathepsin D, interleukin-1 receptors were highlighted potential geosmin targets, annexin demonstrating highest binding affinity silico. provides robust protocol integrating silico approaches elucidate geosmin's tissue, advancing our understanding pollutant-biological interactions enhancing environmental risk assessment accuracy.

Abstract Cyanobacteria bloom and the secondary metabolites released by microorganism are extremely harmful to aquatic animals, yet study on their adverse effects in zoobenthos is rare. Corbicula fluminea widely distributed freshwater environment with algal blooms. It a typical filter feeding that may be affected of cyanobacteria due its high filtering rate.
