River shrimp is an omnivore, and it feeds on plankton in the juvenile stage. The main food of adult shrimp is various benthic small invertebrates, aquatic animal carcasses, sessile algae, various filamentous algae, organic debris, plant fragments, etc. Cultured shrimp can eat various commercial feeds, such as distiller's grains, bean curd residue, bean cake, silkworm chrysalis, mussel meat, wheat flour, fish meal and so on.

River shrimps are widely distributed in rivers, lakes, reservoirs and ponds in China, and are high-quality freshwater shrimps. Wild river shrimps eat many foods, such as fish, shrimp, snail and mussel, and some also eat aquatic plants or algae. This animal has a wide range of feeding habits, and if it is raised artificially, it can choose a wide range of feed, and even feed fish food.

Life habits of river shrimp:

1, Macrobrachium macrobrachium belongs to omnivorous aquatic animals, which are partial to animal feed, and the artificial culture is mainly based on commercial feed. The optimum water temperature for its growth is18 ~ 30℃. When the water temperature drops to 4℃, it will enter the wintering period, and when the water temperature rises above 10℃, its vitality will be enhanced and its feeding will be gradually strengthened.

2. Camping for benthic life, I like to inhabit the slow-flowing place where there are many aquatic plants, and the water depth varies from1-2m to 6-7m. In summer and autumn, river shrimps seek food and breed in shallow water on the shore, and in winter, they move to deeper water areas for wintering, with little food and activity.

3. When the water temperature 18℃ or so, the sexually mature shrimp begin to mate and lay eggs, and mating often occurs near the time of laying eggs.

4. Shrimp is backlit, hiding in the dark during the day and coming out at night. The reproductive season is uncharacteristic, and it will also come out for mating activities during the day, and when feeding, it will also come out for food during the day.
