Herring Fish Facts  -  proper way of hand wash dishes in a restaurant
Conch is widely found in the shallow waters of the North Atlantic and North Pacific.
They have a small head and bright silver body.
Here you can find some interesting facts about herring, such as their hunting style, reproduction and special habits to form the school.
There are about 200 herring species belonging to the clu family.
The name is used in several species of the family.
However, the most important dominant species of herring belong to Clupea, which is known as Clupea harengus, Pacific herring (Clupea pallasii), and Araucanian herring (Clupea bentincki) about 90% cm herring were caught, more than half of which were in the Atlantic Ocean.
This is a small silver fish.
An important feature is that they have individual dorsal fins that are different from other fish that do not have side lines or thorns.
There are several species with sharp scales.
The tail forks like a fork.
They have a prominent jaw on their small heads, flat, slender, smooth body on the side.
Their flashy colors help to hide them in the surrounding water and protect them from predators.
But the same features can also help humans catch these fish easily.
Atlantic herring can grow to 18 inch long.
It is characterized by the fragility of the body and a shuttle shape (the ends are gradually thinner ).
The dorsal fin can be found halfway.
It's green or gray.
The back is blue and the abdomen is silver.
It can be distinguished by a unique small tooth ring located at the top of the mouth.
The weight of this fish can reach 1 pound. 5 pounds.
Pacific herring can grow up to 15 inch, distinguished by its lateral compressed body, a single dorsal fin located in the middle of the body, and a tail fin with a deep bifurcation.
The abdomen and sides are silver.
White, blue behind. green in color.
The fish does have scales on the head and on the thorn, but there are large protruding scales on the abdomen.
Araucanian herring, also known as the Chilean herring, is dark blue in dorsally and silver in the abdomen.
The Baltic herring is a little smaller than its relatives, reaching only 14 to 18 cm.
Herring was found in the temperate waters of the North Pacific and the Atlantic.
Atlantic herring is found in Maine Bay, English Channel, Fendi Bay, Danish Strait, Norwegian Sea, North Sea, Celtic Sea, Irish Sea and other places, as well as Biscayne Bay.
From Northern California to Alaska and the Bering Sea, Pacific herring can be found off the California coast.
In Asia, it can be found in southern Japan.
Araucanian herring was found in South America.
These fish thrive in tiny creatures such as plankton, shellfish and fish.
Plankton is the main source of food for juvenile fish, while adult fish are the source of food for plankton, such as full, winged and small shellfish, as well as shrimp, fish, snails and small fish, even small animals.
They keep their mouths open while swimming, and in the process filter plankton through their fins.
Herrings reached sexual maturity at the age of 3 to 4.
Their life expectancy is between 12 and 16 years old.
However, Australian herring can range from 23 to 25.
Fertilization is external because both females and males release a large amount of sticky eggs and milk at the same time.
Some fish go to coastal rivers to spawn.
Atlantic conch usually spawn in coastal waters and offshore banks. Mid-
Summer and December are ideal times for spawning.
Eggs usually take about two weeks to hatch.
Female fish can spawn 20,000 to 40,000 depending on the size and age of sinking to the bottom and sticking to gravel, stone, seaweed and other objects.
About 1 to 1 egg.
With a diameter of 4mm, they cannot survive at temperatures above 66 degrees Fahrenheit.
The hatched larvae are usually 5 to 6mm long and the body is almost transparent.
However, the eyes are colored and have a small yolk sac that will eventually be absorbed as the larvae grow.
When the larvae reach a length of about 40mm, it looks like a small green fish.
Juvenile fish are generally adult in about 3 to 4 years.
During the day, they stay in deep water to avoid their predators.
But at night, when predators see their risk decrease, they surface and open their mouths while swimming.
So they filter plankton that happens to pass through their fins.
When the concentration of prey reaches a high level, all members of the school open their mouths to swim and their camp is completely open.
Juvenile fish prey by swimming in the grid and keeping a fixed distance between them, which is equal to the length of their prey jump.
By sensing a pressure wave, copepds uses an antenna to detect predators.
Therefore, when a porpoise senses a predator, it jumps to escape at a constant length, which takes about 60 ms per jump.
At this point in time, the endless herring flow that swam in that direction finally allowed people to capture copepd.
There are many predators in Herring.
In addition to humans, marine mammals such as dolphins, killer whales, whales, seals, sea lions, as well as fish such as sharks, salmon, tuna, cod, big hali fish, sailfish, etc, the main predator is striped bass.
Seabirds are another important type of predator.
Humans have consumed herring since 3000. C.
They are of great commercial and economic importance to humans and are used as delicious in many pasta and salad dishes.
It can be fermented, pickled, smoked, pickled, or eaten raw.
They are also used to make fish oil.
These fish are rich in vitamin D, omega-
3 fatty acids and DHA (22 carbon six carbonated ).
It is well known that herring is swimming in large groups and is called a school.
In order to spawn, they usually move in groups to the shore in the same direction.
When swimming in large schools, they provide food for large predators.
It is estimated that a herring school in the North Atlantic can reach up to four.
The density of fish is 8 cubic kilometers between 0.
5 to 1 fish per cubic meter, which means there may be billions of fish in a school.
The most interesting fact about a school is that it has a precise spatial arrangement that helps maintain a relatively constant cruise speed.
It is not clear why fish like herring form a school.
Predator confusion, better simultaneous hunting and better positioning are possible advantages.
However, there are also shortcomings in school education, because it can lead to the depletion of food and oxygen, as well as the accumulation of excretion products in the respiratory medium.
