- Abstract
- The feeding habits of the Pacific herring Clupea pallasii were examined based on 333 specimens collected from the coastal waters of the East Sea of Korea. Sampling was conducted in April, June, and September 2019 and February 2020. The total length of the C. pallasii ranged from 11.9 cm to 37.7 cm. Euphausiids (93.0%, index of relative importance, IRI ), especially Euphausia, comprised the primary diet of the pacific herring, in addition to amphipods, copepods, and fishes. The dietary composition of C. pallasii showed non-significant differences by size. As body size of C. pallasii increased, the mean number of preys per stomach (mN/ST ) and the mean weight of preys per stomach (mW/ST ) tended to increase.
