In order to examine the seasonal variations in morphological characteristics and diet of Mactra veneriformis Northern Yellow River Delta’s intertidal zone provide a scientific basis for its resource conservation population restoration, tested clams were collected four consecutive seasons from summer 2022 spring 2023. Morphological traits measured, DNA stomach contents was analyzed using high-throughput sequencing. The tidal differences northern habitat Estuary significantly affect growth M. veneriformis. Among seasons, significant observed between middle-tide low-tide zones (p < 0.05). both zones, body wet weight winter higher than those other Moreover, extremely influenced by interaction tide season (two-way interaction, p 0.001). all middle- exhibited positive allometric growth. While there no difference content samples same > 0.05), This suggests that variations, rather differences, had larger impact on estuary feeding may be related changes environmental factors, such as temperature. findings this study initial insights into ecology offer foundation management resources.
