Why are wild river fish always in demand?

According to experts, wild river fish often have a price that is 6-10 times higher than farmed river fish. For example, if we take the case of catfish, the buying price from a source for farmed fish is only 100,000-150,000 dong/kg. But for fish caught in the wild, the price can go up to 850,000-900,000 dong/kg. Similarly, if it’s farmed river carp, it’s only priced at 60,000-70,000 dong/kg, but if it’s caught from the river, the price can be as high as 350,000-400,000 dong/kg,…

In particular, wild river fish are now quite rare, and there is not always enough supply to meet demand. Because the supply is low and the demand is high, many small traders try to pass off farmed fish as wild river fish to make a profit. With these fraudulent practices, small traders can quickly become wealthy.

However, with years of experience in the industry, experts share the secrets to help you identify natural fish and artificially grown fish.

By observing their external characteristics, keen-eyed buyers can easily distinguish between farmed river fish and wild river fish. For example, natural river fish always have small heads, long bodies, slim bellies, and less fat. In addition, their fins, tails, and whiskers are usually longer than those of farmed fish. When they are cut open, their intestines and stomachs are smaller, and when a knife is inserted, the fish’s meat feels crispy,…

These characteristics are due to the fact that wild river fish move a lot, they forage all day, so they have a leaner body to adapt to the harsh natural conditions, Mr. Tue said.

On the other hand, the most noticeable characteristic of farmed river fish is their big bellies and short bodies because they are less active as they are confined in cramped cages. Moreover, farmed fish are fed multiple times a day, so each time they eat a lot, their stomachs fill up with food, making farmed fish always have much larger bellies.

Frequently asked questions

By examining the fish’s lower tail area, you can determine whether it is wild or farmed. Wild fish will have a mark in this area, indicating that they are wild-caught. This mark is absent in farmed fish, as they are raised in controlled environments and their tails remain untouched.

Knowing the source of your fish is crucial for several reasons. Firstly, wild fish are known for their superior taste and texture due to their natural diet and habitat.
