The data file to Shvydka et al, 2020. Patterns of monogenean abundance in native and invasive populations of Planiliza haematocheila (Teleostei: Mugilidae): interactions between climate and host defence mechanisms explain parasite release

Abundance data of Ligophorus llewellyni from the pacific so-iuy mullet, Planiliza haematocheila, in the Azov and Japan Seas with information on locality, month, season, year, host total length (TL), weight (W) and relative host condition (Krelative).本数据集收录了采自亚速海与日本海海域内太平洋红鳍鮻（so-iuy mullet，Planiliza haematocheila）体内卢氏指环虫（Ligophorus llewellyni）的丰度数据，附带采样地点、采样月份、采样季节、采样年份、宿主全长（TL）、宿主体重（W）以及宿主相对健康状况（Krelative）等相关信息。
