CATDOLL : CATDOLL: What is the difference between freshwater farmed salmon and other fish?

1. What is the difference between freshwater farmed salmon and other fish?

Rainbow trout belongs to the genus Salmon, while true salmon belongs to the genus Salmon. The taste, nutrition and price of rainbow trout are very different from those of Atlantic salmon. Due to the similarity of the fish meat, rainbow trout is often sold as "salmon" in the market. Because it is farmed in freshwater, some merchants often call it "freshwater salmon", which seems a bit funny! If consumers do not carefully distinguish, facing different "salmon", it is likely to go against your original purchase intention! In particular, friends who love to eat salmon sashimi need to pay more attention. Rainbow trout is not suitable for raw consumption, and freshwater sashimi is best not to be eaten! Don't eat it raw! Don't eat it raw! Important things are said three times!



Below, we teach you how to distinguish real salmon from rainbow trout.

Tips for distinguishing salmon from rainbow trout

Complete fish body to see the characteristics

size:

Atlantic salmon usually weigh more than 10 kilograms and are 1 meter long.

Rainbow trout usually weighs about 3-4 jin, and the largest is about 8 jin. It only grows about 1 jin a year.

Appearance:

Atlantic salmon are silvery grey with some black spots.

Rainbow trout have a pink line on the side of their body, which makes the difference very obvious.



Cut the fish pieces into pieces and see the details:

Fish skin:

The scales of Atlantic salmon and their skin after descaling have a diamond pattern; the scales of rainbow trout are fine and dense, with a circular pattern.

Color and Texture:

Atlantic salmon meat is bright in color, orange-red in color, with clear fat lines, firm and solid texture, and no blood or bruises.

The color of rainbow trout meat is reddish, and the lines are scattered. Because the whole rainbow trout is smaller than salmon, the patterns are relatively denser, and the intervals between the lines are a little narrower. In contrast, the meat of freshwater fish is relatively loose. (The fish meat on the right at the beginning of the article clearly meets these characteristics!)



Cooked fish: Look at the color and taste

The cooked salmon is light pink in color, tender and delicious, sweet in the mouth, and the meat is firm and relatively complete.

The cooked rainbow trout is relatively darker in color, a bit woody when eaten, and the meat is loose and easy to break apart.



Look at the price? Or not!

Norwegian salmon is relatively expensive. However, judging by the price seems to be unreliable! After all, fish cannot be changed, but the price can be changed. I hope that when you buy salmon, you can combine the above characteristics and details to distinguish the "salmon" you need.

The names of aquatic products are complicated and require deep identification

As the salmon consumption market expands, the definition of "salmon" has become more controversial. For example, some people call rainbow trout "freshwater salmon", but whether this is reasonable or not is not clear. Manufacturers do not indicate the scientific name of the aquatic product, but use the name "salmon" for all aquatic products. Different aquatic breeding methods have different nutritional values ​​and eating methods. Is this a bit unfair to consumers who are not familiar with the characteristics of aquatic products?

Friends should decide whether to buy salmon or other fish, as well as the cooking method, based on their own and their family's physical conditions. It is recommended that rainbow trout be cooked. The "salmon" sold by many businesses now is actually rainbow trout!

Freshwater farmed salmon is rainbow trout, which is a different species.

The fish may contain high levels of parasites from the freshwater salmon environment, which can be harmful to human health (but you don't have to worry about parasites in saltwater salmon, as they have no effect on humans, so it's okay to eat them raw). Try not to eat freshwater salmon raw.

If you don’t eat it raw, what’s salmon? Well, this is a paradox.

2. What is the difference between salmon and sashimi?

Salmon and sashimi are not the same type of thing, so the only difference is: salmon is a fish and sashimi is a dish.

(1) Salmon is the common name for some salmonids. It is also called salmon or salmon. It is one of the most commonly used fish ingredients in Western cuisine. In the consumer markets of different countries, salmon covers different types. Norwegian salmon is mainly Atlantic salmon, Finnish salmon is mainly farmed large-sized red meat rainbow trout, and American salmon is mainly Alaskan salmon.

(2) Sashimi refers to fish sashimi, raw fish, and sashimi. It refers to dishes made by cutting fresh fish and shellfish into slices and eating them directly with seasoning.

Additional information:

The most commonly used material for sashimi is fish, and the freshest fish. Common ones include tuna, sea bream, flounder, bonito, salmon, sea bass, mullet and other marine fish; there are also light fish such as carp and crucian carp.

In ancient times, carp was once the top-quality ingredient for making sashimi. Nowadays, sashimi is no longer limited to fish ingredients. Snails (including snail meat, oyster meat and scallops), shrimps and crabs, sea cucumbers and sea urchins, octopus, squid, cuttlefish, whale, as well as chicken, venison and horse meat can all become ingredients for sashimi.

3. Salmon farming, please check the farming methods

1. Choose a venue

The most important thing about salmon farming is choosing the right place to farm. You need to choose a freshwater area and there should be no pollution sources around it.

2. Release fish fry

In the early stage of salmon farming, the size and weight of salmon need to be controlled. If the size is too small, it will be threatened by salmon and other fish. In order to effectively ensure the smooth growth of salmon, it is recommended to use salmon fry of equal weight.

3. The size of the venue

When farming salmon, you need to choose a larger farming area as much as possible. If the area is too small, it will be detrimental to the normal growth of salmon and will also limit its growth. A large area can increase the growth rate of fry and increase production.

4. Choose Food

There is no specific food to feed salmon when they are raised artificially, but you can buy some professional salmon feed on the market and feed them mixedly.

Differences between golden trout and salmon

Golden trout was originally a variant of rainbow trout. Because of its golden color, it is called golden trout. Like rainbow trout, it is a cold-water fish. It originated from the Pacific coast of North America. At present, golden trout farming has spread across five continents, becoming one of the most widely distributed fish in the world. Although it is a cold-water fish native to the northern hemisphere, it has now moved to the southern hemisphere and even the southernmost tip of Africa, and the farming height has reached waters over 4,500 meters above sea level. In addition to Canada and the United States, the farming areas include New Zealand, Australia, South America, Africa, East Asia and South Asia, and almost all of Europe. Golden trout is a cold-water fish with tender meat and fresh taste. It is rich in amino acids and trace elements needed by the human body, and has carbonyl esters that can dissolve blood clots. In addition to being edible, golden trout also has ornamental value and breeding research value. It is one of the excellent freshwater aquaculture varieties promoted to the world by the Food and Agriculture Organization of the United Nations.

Salmon is a general term. Salmon is the transliteration of the English word Salmon, which means "Salmonidae" or "orange-red salmon meat" in English. Salmon is divided into the genus Salmon and the genus Trout, so to be precise, Salmon is salmon and trout. The most common salmon in the consumer market in mainland China is the Atlantic salmon.
