Under the multiple influences of environmental changes and human activities, the fisheries operating environment in Taiwan has become increasingly challenging. Changes in the marine environment not only alter the migration path of fish schools, but also affect the time and space of fish school distribution. Moreover, the fishing ground might also be affected or even disappear. Larvae of fish is an important life stage before the fish joins the fishing ground. Analysis of larvae information can help us improve the understanding of the changing nature of fishing grounds. In this regard, this project will continue to count on our fisheries researchers and use relevant equipment to monitor fishing grounds around Taiwan, collect and analyze environmental information, and monitor larval in Taiwan’s surrounding waters over the years, and carry out larval of fish geography, seasons, diversity and abundance of different habitats. The results of the study show that there are different distribution patterns of larvae in the six landforms around Taiwan. The larvae of fish species such as Notosudidae Spp., Sigmops Gracilis, and Mugilidae Spp. mainly appear in winter. The probability of Decapterus Spp. appearing in spring is significantly higher than in other seasons, and the probability of it appearing in autumn of Auxis Spp., Decapterus Macrosoma and Trachurus Japonicus approaches zero. Through Clustering analysis, it can also be found that topography affects important factors in the composition of larvae of fish, and currents such as Kuroshio may cause changes in the composition of larvae and juveniles at some stations. This study also shows that the larvae abundance of fish species in different water layers has regime shift in recent years, but the reasons for the impact still need to be further studied and confirmed.
