摘要:
Length-weight relationships were determined for three freshwater fish species from the northeastern China. Fish specimens were sampled quarterly across the Songhua River and Nen River from October 2016 to September 2017 using multiple gears. Relationships between length and weight were fitted very well for all species (all R-2 > .95), with b values ranging from 2.931 for Perccottus glenii to 3.044 for Parabotia mantschurica. The relationships for three species (P.mantschurica, P.glenii and Tachysurus brashnikowi) were new to FishBase database.
