CATDOLL : CATDOLL: How to make aquaculture cages to temporarily raise eels?

1. How to make aquaculture cages to temporarily raise eels?

The cage can be made of nylon mesh or wire mesh. The cage is 2 meters long, 2 meters wide, and 0.6~1 meter high, or 3 meters long, 1 meter wide, and 0.6~1 meter high. There are two types of cages: floating and fixed. For raising eels, open fixed cages are mostly used, and floating cages can also be used in waters with large water level fluctuations. The upper mouth of the fixed cage is supported by a bamboo frame, and a thick bamboo pole is tied to each of the four sides, and the four corners of the lower mouth are tied to the bamboo pole.

There is a lid on the top of the net, and a hole is made on one corner of the lid, which is usually covered. When fishing for eels, untie the hole and reach into the sea to catch them. The net cage can be placed in ponds, reservoirs, rivers, ditches, and harbors. As long as the water is not polluted, there is no water shortage in summer, and there are some winds and waves but not too big. When placing the net cage, the widest side of the net cage should face the water flow or the direction of the wind that often blows. Four thick bamboo poles should be driven into the bottom mud. The depth of the drive should be such that 10 cm of the net cage is exposed above the water surface.

2. Is it profitable to farm eels in small ponds and cages?

The benefits are not bad. I have raised eels for eight years. In two years, the net increase can be 2-5 times. Technology is the key factor.

3. How do I choose salmon? Is this piece of salmon good?

This is a complete side section of the salmon in the middle and back. The wide lines on the top are the fish belly, and the meat on the back is below. When cutting, just cut it into three sections along the lines. The part is actually not bad.

4. Smoked salmon?

You can use the grill function of the microwave. Marinate the salmon and grill it. The second method is to put sugar and tea leaves in a frying pan and put the salmon on top in the center of the pan (the salmon should be flavored). Cover the pan with a lid after the smoke comes out of the pan. Turn off the heat and wait until the smoke stops. Smoked salmon slices, mixed lettuce, black olives, capers, toast, horseradish, lemon juice, and vinaigrette (1) Roll up half of the salmon slices into a flower shape, place in a bowl, squeeze lemon juice on it, and place mixed lettuce around it. (2) Cut the black olives into slices horizontally and place them in the bowl with the capers. (3) Cut the toast into thin slices, cut off the crust on the four sides, cut into triangles, put in the oven, dry, and place vertically on the salmon. (4) Use a small teaspoon to scoop a small amount of horseradish, place it on the salmon, and pour a small amount of vinaigrette on the outside of the bowl. Special care a. Ripe pitted olives and capers, which are generally available in large domestic supermarkets. b. Horseradish, which is often used as a seasoning for beef and cream dishes. c. Vinaigrette can be made with olive oil, vinegar, etc. according to your preference

5. Does smoked salmon cause cancer?

Ask on Baidu, cold smoke, lots of results.

Whether it is cold smoking, warm smoking or hot smoking, smoke is needed. Aren't the smoke from burning wood and the smoke from burning tobacco leaves both incomplete combustion? Are there any essential differences in the PAHs they contain?

So if it causes cancer, it will still cause cancer, and you still have to eat it.

6. Is it good to eat salmon for a long time?

Of course

I like salmon, especially salmon sashimi. A light bite, the tender and smooth taste is more intoxicating than the lips of a lover. A careful taste, the sweet taste is more unforgettable than the April day.

I feel great after eating this. I feel great the more I eat this. I feel great the longer I eat this.

7. Can cats eat salmon skin?

The answer is: Yes.

Let's first learn about salmon. The salmon currently sold in my country can be divided into two types: imported and domestic. Most imported salmon comes from Norway and Chile, and is called salmon. It has plump meat and rich nutrition.

There is also a small amount of salmon from Russia, also known as salmon, which has relatively poor meat quality and nutrition.

The domestic ones are called rainbow trout, and the National Fisheries Association has approved it to join the salmon family. However, the meat quality, taste and nutrition are far inferior to imported varieties, and because they are farmed in freshwater, they will have parasites.

Of course, most of the salmon imported from Norway and Chile are also farmed in the ocean, and there are not many truly wild salmon suitable for fishing in nature.

Domestic salmon skin is not suitable for animal consumption, mainly due to parasite problems.

Imported salmon skin is actually a kind of complementary food and snack suitable for cats and dogs. It has gradually become popular in Europe.

The reason is that salmon skin itself has high nutritional value. The ratio of crude protein 60%, minerals, crude fat 15%, water, and crude fiber 2.5% is very reasonable. In particular, it is rich in unsaturated fatty acids omega-3 up to 0.6%, which is a nutrient that cats cannot synthesize themselves but is very important for their health. In addition, the content of natural collagen in fish skin is much higher than that in fish meat. Eating salmon skin regularly can promote the health of cats' cardiovascular system and brain development, lower blood sugar, prevent calcium loss, reduce the risk of skin diseases, and delay the aging of body cells.

The downside is that the fat content is high, so you can't eat too much in a day.

In fact, most cats don't like to eat pure natural fish skin, probably because it tastes too fishy and is too tough, so it usually needs to be processed to adjust the taste, reduce fat content, and kill bacteria and parasites while ensuring that it is as natural as possible. There are similar products on the domestic market, and it is estimated that they will become popular in the domestic market in recent years!

8. How do you evaluate platinum salmon products?

I feel it is OK. I use Platinum Salmon, which is a medical device product with formal approval documents. It mainly contains PDRN (polydeoxyribonucleic acid) and fullerene. These two ingredients have the effects of anti-wrinkle, beauty and anti-aging. They can improve the problem of skin tissue recovery from the root, and the effect after I use it is still very good.

9. Tuna, sardines, salmon?

There are about 4 or 5 brothers and sisters in the tuna family. The most handsome one lives in the Pacific Ocean. His tail is a little blue. He has a high status in their family. He is also fat and grows rapidly without regard for his life. He is also very handsome, so everyone likes to call him the blue fat man.

There were several brothers and sisters, one with particularly big eyes, called Big Eyes Girl, one with a yellow tail, called Butter Hands, and some relatives and friends. Anyway, they were all hanging out in the ocean. No one knew which unlucky guy was captured by the Japanese and brought to land first, thus bringing disaster to the entire family.

The Japanese at that time had never seen the world. They couldn't even start a fire. They were lucky enough to be able to cook rice. Fish could only be eaten raw. The bluefin tuna was really fat and had a bit of fatty liver. When you cut open its belly, you could see it was full of fat. It tasted greasy in your mouth, and with some mustard and soy sauce, it was really delicious. So the way of eating it as sashimi became popular in Japan. Everyone wanted to taste the bluefin tuna. As more people ate it and it became famous, other relatives were not spared. Those that could not be eaten as sashimi were thrown into the factory and processed into various canned foods. They were overfished every year, and later there was a policy to restrict fishing. Artificially farmed tuna was gradually industrialized. After so many years, people's love for them remains unabated, so the price has remained high. As for nutrition.

Sea fish are very nutritious...

The salmon family is a little more complicated, but there is one that stands out the most, which is Atlantic salmon and Norwegian salmon. They are treasures all over, and the fish meat can be used as sashimi. The three cut half bodies with fish belly fell from the chopping board. The orange luster and rich oil have made an indelible contribution as the enlightenment godfather of Chinese people eating sashimi. The salmon roe is processed with the Japanese soy sauce method and can be used as a versatile side dish. The salmon head is used for grilling, the salmon fins are used for braised in sauce, and the salmon bones are used for making miso soup. Almost single-handedly, it has made the Chinese Internet celebrity pseudo-Japanese izakaya sweep China's first- and second-tier cities, and become a must-have place for urban beauties and spirited young men to date after get off work, enjoy the good life, and take photos and check in.

Norway has already industrialized salmon farming. We don't know the total amount exported each year, but it's a lot anyway. The price was okay in the past few years, but it went up a bit during the epidemic, and it became unaffordable. Do you remember the fresh food brand under Lenovo, Joyvio? They spent a lot of money to acquire a salmon producer, but it was hit hard by the epidemic. They lost dozens of US dollars for every fish sold, and they were so depressed that they went ST. It will probably take a few years for the market to recover. The price seems to have stabilized a bit recently. I haven't eaten it for a long time, and it's still expensive.

It has a lesser relative, called rainbow trout, which looks very similar to it and is also cheaper, but a friendly reminder: don't eat it raw. As for the nutritional value of salmon.

Sea fish are very nutritious...

Sardines, my favorite. I think you have probably seen the sardine storm in the aquarium, or people who love diving should all know that the small fish, the social animal, the very fast fish is the sardine. Although it looks inconspicuous, it is very delicious and cheap. Fresh ones can be made into sashimi or tempura. It is very plastic. Sardines rice bowl, sardine sushi, and raw eggs are also very suitable.

I once ate at a specialty sardine restaurant in Osaka. The sardines were kept in a large fish tank. The food was delicious and left a deep impression. As for the nutritional value of sardines, what about them?
