2013和2014年5~6月间，采用自制悬挂式电鱼机，在鸭绿江支流蒲石河采捕368尾杂色杜父鱼 Cottus poecilopus Heckel，研究该鱼的生物学。结果表明：杂色杜父鱼全长 L（mm）与体质量 W（g）的关系式为： W=2×10-5L2.9662。48尾雌性个体的统计表明，个体绝对繁殖力（F）为497粒，体长相对繁殖力（FL）为5.06±2.13粒/mm，体质量相对繁殖力（FW）为36.98±15.63粒/g。杂色杜父鱼的摄食率为28.26%；充塞度为1~5级的标本尾数分别占总标本数的38.46%、26.92%、19.23%、11.54%，和3.85%；主要食物为底栖动物和小型鱼类。饵料生物中个数百分比（N%）最高的种类是灰纹石蛾 Hydropsyche ulmeri，质量百分比（W%）和出现频次百分比（F%）最高的均为钩虾 Gammarus sp.，百分比相对重要性指数（IRI%）最高的是灰纹石蛾 Hydropsyche ulmeri。
