What Do Freshwater Shrimp Eat? Omnivorous Habits and Common Bait Introduction

Freshwater shrimp are typical omnivores with a very broad diet. In the wild, they feed mainly on plankton, algae, tender leaves of aquatic plants and organic debris in the water, and they also prey on small aquatic animals such as aquatic earthworms, insect larvae and snails, often showing greater interest in animal-based bait.

Their feeding habits differ across growth stages. Juvenile shrimp mainly filter-feed on tiny organisms such as planktonic algae and rotifers, and as they grow larger they gradually shift to feeding on larger plant and animal debris and small bottom-dwelling animals. Freshwater shrimp mostly come out to forage at night and in the early morning, and often hide in water weed clumps or rock crevices during the day.

For artificial culture, baits from a wide range of sources can be chosen. Commonly used ones include plant-based feeds such as soybean milk, soybean cake, wheat bran and rice bran, paired with animal-based baits such as fish meal, snail and mussel meat, and small trash fish; special compound feed can also be fed directly, with occasional supplements of chopped green vegetable leaves.

When feeding, pay attention to regular timing and fixed amounts. Freshwater shrimp like to be active in the evening, so a somewhat larger amount can be fed in the evening; leftover bait should be cleaned up promptly to avoid spoiling the water quality. If only a single feed is given over the long term, the shrimp are prone to nutritional deficiency, so the proportion of animal-based bait can be appropriately increased. Keeping an appropriate amount of aquatic plants in the culture water not only provides natural bait but also gives the shrimp convenient places to rest and molt.
