Abstract

Sound is critical in fish behaviours, including reproduction, feeding, predator avoidance and habitat selection. To investigate the impact of underwater soundscape on the distribution of Cobitidae fishes, we surveyed the status of Cobitidae fish resources and the underwater soundscape along with related environmental factors at 12 sampling sites downstream of the Songxin Hydropower Station in the Heishui River, a major tributary of the Jinsha River in China. Generalised additive models (GAMs) were employed to identify the primary environmental factors influencing the distribution of Cobitidae fishes and we analysed the correlation between the abundance of Cobitidae fish and primary environmental factors. The study revealed that the water depth, flow velocity, water temperature and sound pressure level (SPL) all had highly significant effects on the distribution of Cobitidae fishes (p < 0.001), with SPL showing the lowest relative importance among these factors. Water depth positively correlated with Cobitidae fish abundance, whereas water temperature, SPL and flow velocity showed negative correlations. This study preliminarily explored the response relationship between the distribution of Cobitidae fish and four main environmental factors, offering a technical foundation for predicting the distribution of Cobitidae fishes in rivers and for implementing conservation measures of fish such as suitable habitat creation.

水下声景观在塑造刀鱼科鱼类分布中的作用：来自多种环境因素的见解

声音对鱼类的行为至关重要，包括繁殖、进食、捕食者躲避和栖息地选择。为探讨水声景观对蛇刀鱼科鱼类分布的影响，在金沙江主要支流黑水河松新水电站下游12个采样点调查了蛇刀鱼科鱼类资源现状、水声景观及相关环境因子。采用广义加性模型（GAMs）确定了影响棘豆科鱼类分布的主要环境因子，并分析了棘豆科鱼类丰度与主要环境因子的相关性。研究发现，水深、流速、水温和声压级（SPL）对刀鱼科鱼类分布均有极显著影响（p < 0.001），其中声压级的相对重要性最低。水深与鱼的丰度呈正相关，水温、声压级和流速呈负相关。本研究初步探讨了蛇刀鱼科鱼类分布与4种主要环境因子的响应关系，为预测河中蛇刀鱼科鱼类分布及实施适宜生境等鱼类保护措施提供技术依据。

期刊介绍： Ecology of Freshwater Fish publishes original contributions on all aspects of fish ecology in freshwater environments, including lakes, reservoirs, rivers, and streams. Manuscripts involving ecologically-oriented studies of behavior, conservation, development, genetics, life history, physiology, and host-parasite interactions are welcomed. Studies involving population ecology and community ecology are also of interest, as are evolutionary approaches including studies of population biology, evolutionary ecology, behavioral ecology, and historical ecology. Papers addressing the life stages of anadromous and catadromous species in estuaries and inshore coastal zones are considered if they contribute to the general understanding of freshwater fish ecology. Theoretical and modeling studies are suitable if they generate testable hypotheses, as are those with implications for fisheries. Manuscripts presenting analyses of published data are considered if they produce novel conclusions or syntheses. The journal publishes articles, fresh perspectives, and reviews and, occasionally, the proceedings of conferences and symposia.
