Fish diversity, an important indicator of aquatic ecosystem health, is declining due to water pollution, overfishing, climate change, and invasive species. Effective surveying monitoring are required protect fish diversity. Here, a high-sensitivity environmental DNA (eDNA) metabarcoding technique was used investigate diversity in the Danjiang River, Shaanxi Province, China. In total, 59 species were identified eight orders, 19 families, 40 genera. Cypriniformes Perciformes main groups survey area, while Cyprinidae accounted for 50.85% total Rhinogobius similis (19%), Hemibarbus umbrifer (11%), Gnathopogon herzensteini (10%), Triplophysa stewarti (8%), Zacco platypus (7%) dominant Eight rare two exotic identified. Combined with analysis historical data, richness using eDNA significantly higher than that captured ground cages. Temperature, pH, oxidation-reduction potential factors affect spatial distribution communities. These results suggest could be new tool broad application prospects; however, local databases must improved. This study provides theoretical data methodological reference protecting managing Qinling Mountains.

Marine trophodynamics refer to the transfer of energy from prey predators. In marine invertebrates and fishes, nutrients obtained through consumption food and/or are stored as reserves in certain tissues organs including liver, muscle, or gonads, that these subsequently used bioenergetic fuel for highly energy-demanding fundamental physiological processes. southern Humboldt Current System, interaction between two migratory resources top species has been observed: swordfish (Xiphias gladius) its jumbo squid (Dosidicus gigas). Because this trophic interaction, store large amounts (as lipids fatty acids) their main organs. However, how acid profile varies various predator is still unknown, potential use biomarkers ecophysiological role it plays. Our results showed a moderate similarity digestive gland D. gigas with profiles gonad, muscle X. gladius, particularly acids: palmitic (C16:0), stearic (C18:0), oleic (C18:1n9), gadoleic (C20:1), EPA (C20:5n3), DHA (C22:6n3). findings on acids System may reveal degree preference have preying squid, gland. both species, high content characterized by predominance saturated, monounsaturated, polyunsaturated be necessary sustain costs involved reproductive processes system.
