How to distinguish between local knives and southern knives?
Qingdao people like to call the striped fish "knife fish", the local and nearby seas of the striped fish affectionately called "local knife fish", the southern belt fish is "tilapia knife". In the eyes of Qingdao people, the local knife is more meaty and delicious than the southern knife, and the two are completely incomparable. This is not completely unreasonable honey juice confidence, the southern sea water temperature is high, the striped fish grow fast, and the quality may be slightly inferior.
If they are all striped fish species, it is difficult to distinguish between local and southern appearance. But if the striped fish you see is yellow-eyed, it may be a "belt fish" from the open sea or tropical waters of Africa or a sand belt fish of the sand band genus.
China also imports the West African forktail band fish of the genus Forktail, and its tail part is forked, which is easy to distinguish. Foreign monks chant, but fish may not be, it is said that these "foreign" fish with rough flesh, insufficient aroma, please pay attention when purchasing.
Another point, also with fish, from tropical waters may have occipital osteomatomas (pictured above), a type of bone hyperplasia. Probably growing so fast that even the bones are proliferating... Qingdao's local fish will not have this feature, you may wish to pay attention to it when eating fish.
Will the fish die immediately after being caught?
It is generally believed that the carrier fish are deep-sea fish that will die due to rapid changes in pressure after being caught ashore (boat).
But the striped fish are not dead houses in the deep sea, they will travel back and forth between deep water and near the surface on a daily cycle. If caught in the shallow time (morning, dusk or night), it will not immediately "explode" and die, but will jump around alive and shine with beautiful silver light, which is not the same as the frozen striped fish that passes through the boat and the silver powder. Fresh striped fish can be eaten raw, no fishy taste, the fish is crystal clear and chewy.
Are there any cultured striped fish on the market?
You can answer categorically: No.
The production of striped fish has always been the highest among all kinds of marine fish in China, easily exceeding 500,000 tons per year; and the resources are abundant, it is simply inexhaustible, there is no need to engage in artificial breeding. There is no motivation without demand, and there will be no results without motivation, so the current artificial culture of fish with fish is still in the stage of domestication of wild fry, and it is said that the survival rate is not high.
How to make delicious with fish?
Fresh striped fish is best for steaming, which is the most original method besides sashimi, with a refreshing and umami taste.
Home-cooked braised pork is also good, the finished juice is rich and fresh, and the fish is soft and tender.
