摘要
裸鲤是一种分布于近海水域的小型鱼类,对中国具有重要的经济价值。了解其分布特征和驱动因素势在必行。基于2018年至2022年中国浙江省近海春(4月)、秋(11月)拖网渔业资源调查数据,分析了该海域胭脂鱼的时空分布。采用随机森林(RF)模型确定了影响赤潮分布的重要海洋因子。分析了重要变量分布之间的关系。结果表明,C. lucidus 主要分布在近岸海域。该物种的尾密度表现出明显的季节性变化,秋季明显大于春季。影响该物种在春秋两季分布的最重要因素是水深。底温、底盐度和溶解氧浓度也是重要的影响因素。这些因素的重要性在不同季节有所不同,而叶绿素 a 浓度和 pH 值对物种分布没有显著影响。本研究揭示了浙江省近海海域栉孔鲷的分布格局以及重要海洋因子对其分布的影响。该研究可丰富菱角藻的调查资料,为菱角藻的科学管理和保护提供基础数据。
Distribution Characteristics and Driving Factors of Collichthys lucidus Species in Offshore Waters of Zhejiang Province, China
Collichthys lucidus is a small fish found in offshore waters that is economically important for China. It is imperative to understand its distribution characteristics and driving factors. Based on survey data of trawl fishery resources offshore of Zhejiang province, China, in spring (April) and autumn (November) from 2018 to 2022, the spatial and temporal distributions of C. lucidus in this area were analyzed. The random forest (RF) model was used to determine the important marine factors affecting the distribution of C. lucidus. The relationship between the distributions of the important variables was analyzed. The results showed that C. lucidus was mainly distributed in coastal waters. The tail density of the species exhibited obvious seasonal variation and was significantly greater in autumn than in spring. The most important factor affecting the distribution of this species in spring and autumn was water depth. The bottom temperature, bottom salinity and dissolved oxygen concentration were also important influencing factors. The importance of these factors differed among the different seasons, while the chlorophyll a concentration and pH had no significant effect on the species distribution. This study revealed the distribution pattern of C. lucidus in offshore waters of Zhejiang Province and the influence of important marine factors on its distribution. This study can enrich the survey data on C. lucidus and provide basic data for its scientific management and protection.
