Speaking of aquatic products, many people are doing it now, but the profits are also different. The general situation is that marine products are more expensive than freshwater products, imported products are more expensive than domestic products, and wild products are more expensive than domestic products. Under normal circumstances, the retail profit of ordinary fish, shrimps, and crabs is about 30%, which is a very average profit. Because ordinary fish, shrimps, and crabs are not rare goods, and they are raised on a large scale in inland areas. In this way, whether it is the purchase cost, transportation, or storage cost, it is relatively small, and the mortality rate during transportation is not high, so 30% profit is also very good.

In comparison, the profit of seafood is much higher, especially some precious seafood products, the profit can reach about 50%. For example, lobsters, some deep-sea fish, etc., many of these seafood products are originally imported, and the purchase price is very expensive. Then add long-distance transportation, there is also death loss in the middle, and it cannot be produced in large quantities, so it is normal for seafood to have a higher profit.

In addition to the above two types of aquatic products, there is another type of processed aquatic products, the profit of which can also be maintained at about 30%. Now with the increase in people's demand for aquatic products, the aquatic product market has also begun to diversify. For example, the demand for some cooked, dried, fresh and frozen products has also seen rapid growth. Such products are generally used in supermarkets, restaurants, and restaurants in cities. In short, the demand for processed aquatic products is also increasing, and the profit is relatively good.
