Summary
A research team has established the first length-weight relationships for five native fish species in the Chinese section of the Yalu River Basin, providing new biological reference data for this transboundary river system. Analyzing 514 fish, the researchers identified distinct patterns in how body weight scales with length: three species showed approximately proportional growth, while two displayed contrasting departures from that pattern. The findings could help researchers estimate fish biomass from length measurements, compare populations, and strengthen freshwater biodiversity monitoring and conservation planning.
