摘要： Simple Summary Understanding the factors that influence the behavior and distribution of creatures is essential for studying the interaction between environment and biology. In this study, we focused on the main environmental factor, water temperature, and its impact on the distribution of hairtail, a specific species. By examining the spatial limits of the hairtail's temperature range, we found that temperature alone does not fully explain its distribution. We expanded our investigation to include salinity and water depth as additional factors. The results showed that the combination of multiple factors significantly reduced the intersection range between hairtail and the defined environmental factors. This suggests that each factor contributes differently to hairtail distribution. To further explore differences in organism aggregation, future research might compare aggregated and non-aggregated variables related to specific areas of water in terms of specific factors. Moreover, we observed that hairtail distribution varied seasonally, with different levels of coverage and proximity to shore. These findings emphasize the complexity of the organism's habitats and the need for a comprehensive understanding of environmental influences. An organism's habits are formed primarily as a result of environmental circumstances. Analyzing an organism's habits and examining their causes requires a thorough understanding of the peculiarities of an organism's living environments. Analyzing the environmental factors necessary for an organism's survival is a crucial component of studying how the environment and biology interact. The favorable temperature range for the species has been discovered in previous investigations of the hairtails' main water temperature distribution range, covering both the water regions with and without the hairtails. It is implied that there may be other elements besides water temperature that also affect dispersion. The hairtail, though, is still the subject of the study. To investigate and confirm the corollaries, salinity and water depth were added as variables. We observed that the intersection of the main ranges of two environmental factors, as well as the main hairtail range of interest, were greatly reduced when compared to a single factor range; the sum of the three factors will further increase the reduction. The primary cause is that the main range of hairtail relative to each factor is incomplete, and the target bodies specified by various factors are very varied. To further investigate the factors that affect the distribution of the organism's active areas, a comparison between aggregated and non-aggregated waters relative to one factor can be done in the next step. A good sequence of environmental elements, namely temperature>salinity>water depth, is obtained in the above analysis procedure by comparing the accuracy and significance of each factor for the primary range of the hairtail. Additionally, it was noted that the main population of the hairtail covered different areas depending on the season, with less coverage in spring and autumn and greater coverage in summer and winter. The main part of the hairtail population also tended to be distributed closer to the coast in summer and winter, and farther offshore in spring and autumn. These seasonal variations may be related to the two distinct reproductive cycles of hairtail, occuring in spring and autumn.
