We examined the effects of eco-physiological stress due to elevated water temperature on survival, movements, and reproductive physiology of benthic cold-water fish (Cottus pollux spp.) with poor swimming ability both by field observations and experimental procedures. Instream obstructions substantially precluded going upstream of amphidromous (middle-egg type) and fluvial land-locked sculpins (large-egg types). Nesting behavior of small-egg type males were rarely observed under high water temperature condition (i.e., 4-5℃ warmer than river water). Together with the finding of lowest survival rates of the larvae of middle-egg type under highest water temperature condition (15 ℃), suggesting negative impacts on their reproductive activity and survival in early life stage. These findings are useful to estimate the negative impacts of elevated water temperature on eco-physiological aspects of Cottus pollux spp.

研究了水温升高对底栖冷水鱼（Cottus pollux spp.）生存、运动和生殖生理的影响。通过野外观察和实验研究发现，该种动物的游泳能力较差。内流障碍物基本上排除了上游的两栖（中间蛋型）和河流内陆锁杜父鱼（大蛋型）。在高水温条件下（即，比河水高4-5℃）。在最高水温（15 ℃）条件下，中卵型幼虫的存活率最低，表明其生殖活动和早期生活阶段的存活受到不利影响。这些发现有助于估计水温升高对污染杜父鱼生态生理方面的负面影响。
