Crayfish and oranges cannot be eaten together as they may cause diarrhea.

1. Crayfish cannot be eaten with the following foods:

(2) It cannot be eaten with pork, dog meat, chicken, venison, and pumpkin.

(3) It cannot be eaten with fruits containing tannic acid, such as grapes, pomegranates, hawthorns, and persimmons. Shrimp is rich in nutrients such as protein and calcium. If they are eaten together with fruits containing tannic acid, such as grapes, pomegranates, hawthorns, and persimmons, it will not only reduce the nutritional value of the protein, but also tannic acid and calcium ions will combine to form insoluble conjugates that irritate the gastrointestinal tract, causing discomfort, vomiting, and Symptoms include dizziness, nausea, abdominal pain and diarrhea. Seafood and these fruits should be eaten together at least 2 hours apart.

(4) It is best not to eat shrimps with eggs.

Because of its omnivorous nature, fast growth rate, and strong adaptability, it has formed an absolute competitive advantage in the local ecological environment. Their feeding range includes aquatic plants, algae, aquatic insects, animal carcasses, etc. They will also kill each other when food is scarce. Crayfish has become an important economically cultivated species in China in recent years. During the commercial breeding process, escape should be strictly prevented, especially to escape into inaccessible pristine water bodies.
