Grass carp fish seeds, or young fingerlings of the Grass carp (Ctenopharyngodon idella), are commonly used in freshwater aquaculture and pond management due to their herbivorous nature. These seeds thrive in ponds, lakes, and slow-moving rivers, where they help control aquatic vegetation. Grass carp are fast-growing fish, typically reaching market size within 12–18 months under ideal conditions. With a mild, slightly sweet flavor, they are a popular choice for consumption and serve as an effective natural method for managing overgrown aquatic plants.
