Table 5 SIMPER analysis showing the percentage of dissimilarity between pre- and post-fishing ban period in the four study reaches, Potou Town (PT), Chishui Town (CZ), Chishui City (CS) and Hejiang County (HJ), in the Chishui River, and the species that most contribute to this dissimilarity for the relative abundance data

From: Changes in fish resources 5 years after implementation of the 10-year fishing ban in the Chishui River, the first river with a complete fishing ban in the Yangtze River Basin

Species

PT (Average dissimilarity = 32.18)

CZ (Average dissimilarity = 40.76)

CS (Average dissimilarity = 39.18)
