What is Ichthyofaunistic biogeography of the Japan (East) Sea: the comparison of various rank taxa for zoning about?

## Aim The aim of the present study is the analysis of the latitudinal distribution of taxonomic richness (number of genera and families) of ichthyofauna at the western and eastern coasts of the Japan Sea for the purpose of identification of natural boundaries, and subsequent comparison with results obtained using the distribution analysis of species richness. ## Location Japan Sea (Korean – East Sea). ## Methods All statistical procedures were based on well‐tried and widely accepted numerical methodology and the STATISTICA program package. For identifying the statistically meaningful (non‐random) maxima and minima in taxonomic richness (__n__), arithmetic differences in the number of taxa at __i__th and __i −__ 1th geographical latitudes and the measurements of as well as residuals in polynomial trends and clustering (Ward’s method) of genera and family lists, were analysed. The relationship between the number and the scope of taxa was approximated by Zipf–Pareto–Mandelbrot frequency distribution: __p__(__N__)=__k/N__^1+^__^k^__, where __p__(__N__) is a relative number of taxa, each of them includes __N__ taxa of the next lower rank; __k__ is a constant. The determination of the
