Look at the size
Which kind of nutrition is high, wild or farmed? Everyone knows that it is wild, because it is pollution-free, pure natural, with higher nutritional value and safer to eat. The wild ones are generally smaller, and the domestic ones are larger. Because farming needs to be fed with various feeds, these wild aquatic products will look particularly large. Next time you buy it, don't keep looking at the big one. It may be cultured aquatic products, and the taste will be very poor.
From the color point of view, wild aquatic products are lighter in color because they are in the wild, and cultured aquatic products are darker than wild aquatic products because they often eat some feed and are artificially intervened. When buying aquatic products, such as picking yellow croaker, the color is not particularly dark, it is wild yellow croaker, which may be cultured or dyed. You should choose carefully.
From the body shape, we can distinguish wild and cultured aquatic products. Because wild aquatic products have a long body and a wide tail, domestic aquatic products do not have this feature. This is the same as flowers cultivated outdoors and indoors. Because it grows freely outdoors and adapts to the wind and rain, it thrives. The flowers cultivated indoors can't stand a little wind and rain, so they are shy and easy to destroy.
The difference between wild and cultured aquatic products can also be distinguished from fish mouths and gills. Because domestic aquatic products live in a net for a long time, the color of gills and mouths is a little light, while the color of wild aquatic products is darker. Wild and farmed are not very good, and people without relevant experience can't tell the difference. Moreover, there are very few wild ones that can be bought on the market now, and most of them are farmed. The most intuitive and common judgment method is that wild prices will be very expensive.
