Secondly, and most importantly, canned herring is something that is really too difficult for most people to swallow.
Take Xiang Yang for example. Not to mention eating it, he would probably vomit it out just by smelling it.
Dai Xiaolong grinned and said, "Brother, these black fish on my boat are all fresh."
Generally speaking, fresh herring is acceptable to normal consumers.
The meat of fresh herring is white in color, firm in texture and delicious in taste. It is generally used to make salted fish products and is suitable for barbecue.
Our country is also one of the main producing areas of herring, and the catching season is generally concentrated at the end of the year.
Many herrings have no teeth or have small, weak teeth.
Moreover, the herring's swim bladder is connected to the stomach, so it can store spare gas in the stomach.
The two protrusions of the swim bladder are connected to the left and right ear cartilage sacs, replacing the fish's eardrums.
Because herring like to live in groups and feed on small plankton.
So most herrings have to swim up to 3,000 kilometers and migrate seasonally to spawn or overwinter, such as the black-backed herring in the Caspian Sea.
So the texture of herring is very firm and very chewy.
In addition, it is worth mentioning that herring is also known as blue stripe, red line fish, Pacific herring, etc.
The output in the Yellow Sea and Bohai Sea regions in northern my country is very huge.
In spring, they migrate south from the North Pacific to the waters near North my country to lay eggs. Their spawning grounds are around islands and reefs far from the shore. After spawning, the herrings gather in groups with the ocean currents and disappear without a trace.
In addition, it is said that herring can adjust its own adaptability to light, so that the fish can smoothly enter various water layers of different depths to capture food, feeding on copepods, pteropods and other planktonic crustaceans and fish larvae.
Herrings generally swim in large schools. A few days before the start of their migration, a few large, brightly colored individuals will lead the way. The dense schools of herring will swim in waters about ten meters deep near the coast for one or two days, and then enter shallow waters covered with seaweed to reproduce.
Herring clustering is very beneficial for their reproduction and effective protection of their fry. At the same time, clustering is a collective action, with everyone working together to facilitate foraging.
In addition, herring has a very wide distribution range.
There is a species of herring that lives in the Atlantic Ocean from Labrador to Florida. The skin on its back is a dark shade of blue-green, and its sides are silvery with four or more dark spots behind the gills on each side.
River herring is the most common species in the Atlantic Ocean, but is also found in the Baltic Sea, the North Sea and the Mediterranean Sea.
It was developed into an emerging local population in the Yellow Sea fishery in the 1970s, with considerable production. This fish is also one of the world's important economic fish.
In my country's East China Sea and South China Sea, there are also round-bellied herrings of the same family distributed. They are only about fourteen centimeters long and are equally abundant in production.
Herring includes small fish such as sardines and herring.
Herring is a seasonal fish and is produced in all coastal waters of my country.
They have no weapons for self-defense in the ocean, and their only way to protect themselves is to swim quickly or form groups that constantly change formations, making it difficult for fish that prey on them to attack them.
Because they often move in groups, modern fishing tools can catch a lot of herring once a school of fish is found.
The iron content in herring is the highest among fish. It also contains nucleic acid, a large amount of vitamin A, calcium and other nutrients.
Xiang Yang asked Dai Xiaolong, "Captain Dai, what kind of herring are you going to take on board?"
There are many types of herring, and the prices vary greatly between the different types.
The most famous herring is the Atlantic herring, which is more common in our stores than other fish. They generally live in the North Atlantic and rarely cross the boundaries formed by floating ice.
However, they have to swim back to the coast of southern Norway to lay eggs. The scales of this fish fall off easily, and it has as many as sixty vertebrae in its body, a record for the herring family.
Baltic herring is a variant of Atlantic herring. This small fish can hardly grow to 20 centimeters even after six or seven years.
They feed on plankton and can easily adapt to freshwater life. Among the Baltic herrings caught, sometimes you will encounter "big ones" with a body length of up to 40 centimeters.
Sea herring is the main fish species in the Baltic Sea, accounting for half of the catch here.
In addition, there is a herring-shaped fish in the Baltic Sea - the Baltic sprat, or herring.
These small creatures account for the vast majority of all catches in the Baltic Sea.
Millet herrings live along the coasts of the Black and Mediterranean Seas, the North and Norwegian Seas, and Tierra del Fuego and New Zealand.
There are so many species to catch that even the most discerning gourmets have a hard time telling them apart.
There are five species of herring in the Caspian Sea alone.
In my country, it is called Caspian herring.
Among them are the common Caspian herring, the sprat and the big-eyed herring that lives in deeper waters.
In the Black Sea there is the Black Sea-Azov herring, while in the adjacent Lake Abolaou there is freshwater herring.
There are four species of black-backed sprat in the Caspian Sea, and four variants of the Volga herring are also well known.
"It is the most famous herring, the Atlantic herring. It is very common in our seafood market. Moreover, those on my boat are very fresh. Some are still alive and kicking. You will have no trouble selling them if you bring them back." Dai Xiaolong said with a smile.
A hint of joy flashed across Xiang Yang's face.
Atlantic herring generally spawn from December to midsummer, with spawning times depending on latitude and temperature, and can live up to 20 years.
Other species of the genus Herring, such as the millet sprat or Nordic sardine and other species of the Clupe family, such as the golden green sprat and the gray sprat, as well as various less common species, are not as tasty as Atlantic herring.
Of course, Atlantic herring is not the best herring. Some fish from other families are also commonly called herring, such as the swordfish, commonly known as wolf herring.
But among so many species of herring, only the Atlantic herring is an important economic fish. The density of its schools and the number of its individuals are unparalleled. It can be said that it is the most produced fish in the world.
There are many different opinions about why Atlantic herring can reproduce in such large numbers. Some say that it is because herring are good at adjusting light, which allows the fish to smoothly enter various depths of water to capture food. Others say that it is because of its strong reproductive ability.
But no matter what, it is a very valuable economic fish.
"Captain Dai, can I come to your boat and see the herrings on your boat?" Xiang Yang asked loudly.
Dai Xiaolong smiled and nodded, "Of course no problem."
After hearing this, Xiang Yang gave Xu Fang some instructions, and then said, "Let's send a speedboat down, and I'll go to the opposite boat to take a look."
Xu Fang nodded immediately, "Captain, I'll go with you."
