水文（水温）和水动力（水深、流速和弗劳德数）因素影响鱼类产卵活动，产卵场为鱼类产卵发生提供适宜的水文和水动力条件。然而，确定鱼类产卵场的位置存在不确定性，特别是对于远洋产卵者而言。这可能是因为这些鱼类在产卵期间具有独特的水文和水动力要求，导致用于定位其产卵场的方法多种多样。因此，本研究旨在通过空间适宜性评价的手段，准确定位鱼类产卵场。本次实验选择了珠江支流东塔产卵河段的四种主要“亚洲鲤鱼”目标品种。首先，我们调查了产卵河段位置的历史信息。使用声学多普勒电流剖面仪（ADCP）测量产卵期间产卵河段的地形和水动力数据。然后，基于空间聚类方法，对潜在产卵场进行空间属性（水深、流速、水温、弗劳德数）聚类分析。聚类分析方法采用k-means聚类；常用于对大量数据进行分类的方法。最后，结合鱼类产卵适宜性曲线对产卵河段的空间适宜性进行分析评价，获得与鱼类产卵活动相关的空间偏好。按比例，结果显示高适宜性 (>0.4) 区域 (60.86%)。而且，弯曲河段和直河段深池产卵适宜度显着高于分叉河段。此外，靠近河岸的地区比河流中游的地区更适合。最后，根据空间适宜性确定了六个潜在的亚洲鲤鱼产卵场的位置。该研究为产漂卵鱼的产卵地的精确定位提供了技术支撑。
Hydrologic (water temperature) and hydrodynamic (water depth, flow velocity, and Froude number) factors affect fish spawning activities, and spawning grounds provide suitable hydrologic and hydrodynamic conditions for fish spawning to occur. However, locating fish spawning grounds is encumbered by uncertainty, particularly for pelagic spawners. This may be because such fish species have unique hydrologic and hydrodynamic requirements during their spawning periods, resulting in the wide-ranging approaches used to locate their spawning grounds. Accordingly, this study was designed to accurately locate fish spawning grounds through means of spatial suitability evaluation. For this experiment, the four major “Asian carp” target species were selected in the Dongta spawning reach, a tributary of the Pearl River. First, we investigated the historical information on the location of the spawning reaches. An acoustic doppler current profiler (ADCP) was used to measure topographic and hydrodynamic data of the spawning reaches during the spawning period. Then, based on the spatial clustering method, cluster analysis on spatial attributes (water depth, flow velocity, water temperature, and Froude number) was conducted on potential spawning grounds. The cluster analysis method uses k-means clustering; a method often employed to classify large amounts of data. Finally, we analyzed and evaluated the spatial suitability of spawning reaches by combining fish spawning suitability curves to obtain spatial preferences associated with fish spawning activities. Proportionally, results revealed a high suitability (>0.4) area (60.86%). Moreover, spawning suitability in curved river sections and deep pools in straight river sections were significantly higher than bifurcated sections. Furthermore, areas near the riverbanks were more suitable than mid-course sections of the river. Finally, the locations of six potential Asian carp spawning grounds were determined according to their spatial suitability. This study provides technical support to accurately locate spawning grounds for the fish that produce drifting eggs.
