Fish Diversity and Environmental Relationships in the Jinsha River During the Initial Phases of the 10‐Year Fishing Ban: A Metabarcoding Approach [PDF]
Ecol EvolUsing eDNA metabarcoding, we identified 61 fish species in the Jinsha river during the early stage of the Yangtze river fishing ban. Fish diversity showed seasonal and regional variation, with Cypriniformes as the dominant group. Key environmental factors like temperature and dissolved oxygen were closely linked to diversity patterns.
