Can you eat the fish roe inside a ribbonfish's belly?
Generally, the roe found in ribbon fish (mackerel) is edible. It is rich in nutrition and has a unique taste, but attention should be paid to the amount consumed and the preparation method. The details are as follows:

Ribbon fish roe is a common edible fish roe. Like the fish itself, it does not contain toxic or harmful substances and is generally safe to eat. Fish roe is rich in high-quality protein, unsaturated fatty acids, and minerals such as calcium and phosphorus, providing various nutrients to the body. With its delicate and savory flavor, it suits many cooking methods. However, excessive consumption may increase gastrointestinal burden, leading to discomforts such as bloating and indigestion. Particularly, fish roe contains relatively high levels of cholesterol; overconsumption may negatively affect blood lipid levels. Therefore, intake should be moderated.
Ribbon fish roe must be thoroughly cooked before eating, as undercooked roe may harbor bacteria or parasites that could cause gastrointestinal discomfort. Additionally, only fresh roe from high-quality ribbon fish should be selected. If the roe appears dark in color or has an unpleasant odor, it indicates spoilage and should be discarded immediately.
