高体鳑(鱼皮)繁殖行为生态学研究的中期报告 摘要： 高体鳑（也称为鱼皮）是一种主要分布于东亚地区的淡水鱼类。本研究对高体鳑的繁殖行为与生态学进行了调查研究。调查结果表明，高体鳑在繁殖季节会聚集于河流中上游的洞穴或隐蔽的岩石缝中进行繁殖。研究还发现，在高水位时，高体鳑会在洞穴或岩石缝中产卵，卵粘附在墙壁或石头上。研究还发现，在繁殖季节，雄鱼和雌鱼的体表会出现明显的色彩变化，以吸引异性伴侣。此外，在繁殖期间，高体鳑的摄食活动会明显减少，其主要食物为底栖动物和水草。 关键词：高体鳑；繁殖行为；生态学；产卵；色彩变化；摄食活动 Abstract: The goby, also known as fish skin, is a freshwater fish mainly distributed in East Asia. This study investigated the breeding behavior and ecology of goby. The survey results showed that gobies gather in caves or concealed rock crevices in the middle and upper reaches of rivers during the breeding season. The study also found that at high water levels, gobies lay eggs in caves or rock crevices and the eggs adhere to the walls or stones. During the breeding season, the males and females of gobies show obvious color changes on the surface of their bodies to attract mates. Additionally, during the breeding season, gobys feeding activity is significantly reduced, and its main food sources are benthic animals and water plants.
