Nested filters and omnivorous species typically don’t need special attention, but the species they prey on often do. This is especially true for smaller fish with limited feeding abilities and weak competitive strength. Some large fish have poor digestion or difficulty eating due to their rough feed texture, making it hard for them to consume certain types of food. Small-scale grass carp, in particular, require careful feeding management.
To ensure proper care, farmers can set up small feeding stations using mesh or bamboo baskets. The number of these feeding areas depends on the size of the pond. The mesh size and fence spacing should be determined based on the body width of the larger fish to prevent them from entering. Only the target species should be allowed into the feeding zones. For example, if the fingerlings grow quickly, it's important to replace the mesh with a larger one in time to avoid blockage.
Feeding strategies also play a key role. In addition to standard pellet diets, it's beneficial to offer nutrient-rich and easily digestible feeds that match the dietary needs of the fish. For instance, during the early summer season, young grass carp can be fed with Pteris viridis and duckweed. As they grow, purple duckweed can be introduced, and later, finely chopped tender grass becomes an ideal food source. This approach not only supports healthy growth but also improves overall fish health and efficiency in feeding.
