The invention provides a method for calculating fish school density of rivers. The method is implemented as the following steps including, firstly, performing preliminary data collection; secondly, calculating the average target intensity TS; thirdly, calculating the fish school individual density Dt and the overall compensating density dc; fourthly, calculating the fish school density D. The method for calculating the fish school density of rivers is based on the hydroacoustics technical principles, can characterize the density of dispersed fish individuals in a surveyed area by calculating individual density, then increase the density through the school compensating density of the area to achieve quantitative representation of the fish individual and school distribution differences of rive environments and accordingly provide a reliable and effective density calculating method for complex fish dispersing and clustering distribution characteristics of the river environments.
