Abstract
The ecology of the mesopelagic fish genus Trachipterus, which is rarely found in oceans, remains unclear. In this study, we found 22 eggs of T. trachypterus and T. jacksonensis around the Ulleung Basin of the East/Japan Sea during ichthyoplankton surveys from 2019 to 2021. The eggs were identified through genetic relationships with the genus Trachipterus based on partial sequences (COI and 16S) or concatenated sequences of 13 protein-coding genes and 2 rRNA genes of mitochondrial DNA. T. trachypterus eggs were discovered in all seasons, but more frequently during the winter. One T. jacksonensis egg that appeared during the autumn was the first in the northwestern Pacific Ocean. Identifying Trachipterus pelagic eggs would provide insight into their spawning ecology and biogeography.
