What is the difference between red trout and salmon?
When red trout is mentioned, many people probably know nothing about it, but if you say salmon, many people know it. In fact, red trout and salmon are quite similar, and it is hard to tell them apart without looking closely. So what is the difference between red trout and salmon?
1. What is the difference between red trout and salmon?
1. Different distribution ranges
Strictly speaking, rainbow trout (red trout) is not salmon. Red trout is a resident population that lives in freshwater and does not migrate across salinity levels, while salmon is a species or population that needs to migrate between seawater and freshwater.
2. Different prices
Basically, the most expensive Norwegian salmon has a market price of about 80-100 yuan/jin, while domestically farmed rainbow trout costs about 30 yuan/jin.
3. Different flesh colors
Norwegian salmon has flesh that tends toward orange-yellow, and the white marbling on its surface is whiter, with wider lines and relatively blurry line edges. It is generally cut into thick pieces (about 0.7cm-1cm), and the thickness is very thick.. Canadian salmon, by contrast, has flesh that tends toward red, and the white marbling on its surface is not obvious. Rainbow trout has less fat, with thin lines and very hard edges, meaning the alternation of red and white is very obvious. Its flesh is relatively firm, and it cannot be cut this thick, otherwise it is tough to chew.
4. Luster
Salmon looks oily and bright, and under light it will faintly reflect light, while rainbow trout is dull and lusterless under light.
5. Taste
High-quality salmon, because it can be cut very thick, gives a firm and full feeling as soon as it enters the mouth, with the fish oil melting on the tongue. Because it is also very elastic, when chewing there is a feeling of the flesh constantly pressing against the teeth and mouth. Rainbow trout does not have this feeling.
2. Does salmon have parasites?
1. Farmed salmon is regularly dewormed, so farmed salmon generally will not have parasites present.
2. Wild salmon, because of environmental reasons, may have parasites present, so wild salmon can suffer from parasitic infections, and therefore eating salmon may mean ingesting parasites.
Overall, the difference between red trout and salmon is still quite large, and it can be distinguished specifically by flesh color, thickness, luster, price, and other aspects.
