How long does it take for a cormorant to digest a fish?

In general, the lifespan of a fish is related to its individual size and age of sexual maturity. The larger the fish, the later it matures and the longer it lives. From this point of view, the world's largest fish, the whale, should live the longest.

Unfortunately, so far nothing is known about its lifespan. It has been reported that the eagle that lives in the Caspian and Black Seas can weigh up to 1,500 kilograms and have a lifespan of more than 100 years; The white sturgeon in the Yangtze River in China has a lifespan of nearly 100 years. Many small fish, such as freshwater fish False Tiger Fish, Herring Turtle, and Whitebait, have a lifespan of only about one year.

Although the lifespan of fish varies greatly between species, the vast majority of fish live between 2 20 years, of which 60 percent are concentrated in 5 20 years, and no more than 10 percent of fish can live beyond 30 years, and only 5 percent of fish live less than 2 years. Among the freshwater fish in China, the life span of silver floating fish: anchovy, red fin white, copper fish, yellow catfish, silver carp, and sand snakehead is between 2 and 4 years; The lifespan of herring, grass carp, silver carp, bighead carp, crucian carp, bream, red fish and mandarin fish is mostly 7 to 8 years, and some can live for more than 10 years.

Marine fish have a shorter lifespan.

In addition, the lifespan of the same species of fish varies depending on the environment. Such as large yellow croaker, off the coast of Zhejiang.

It can live for 29 years, while in the coastal areas of Fujian and Guangdong, it usually only has a lifespan of 17 years, and when it comes to the eastern waters of Hainan, it only lives for 9 years.

Sometimes it depends on how well you raise it.

Cormorants have a throat sac that can be inflated, which is good for digesting the fish, and the cormorant can vomit out the undigested parts of the stomach.

Cormorants, commonly known as crows and ospreys, live in the reeds of the swampy areas of lakes and eat fish as their main food. It has a complete webbed membrane between its toes and is very good at swimming; It has keen vision and a hard, sharp hooked mouth. At the tip of the esophagus there is a throat pouch that can be inflated to store the fish it catches.

Once it swallows the fish in its stomach, the flesh is quickly digested, the bones wriggle back and forth in the stomach, and the gastric juice wraps the bones into pills, in order to lose weight, speed up the flight, so as to quickly escape the enemy. Cormorants spit out undigested fish bones, scales and other foods in their stomachs with a mucus sac and spit them out of their mouths.

The principle of cormorant eating fish digestion is actually in its throat sac, which can be inflated, so it can eat a lot of relatively large fish, and its stomach can digest the fish meat well, and the undigested fish bones are spit out from its mouth.

Because it is good at fishing, and has the characteristics of the throat sac, it has been domesticated as a kind of bird that can fish, although it lives by the sea, but it does not belong to the seabird. Its digestive system is relatively unique, in many birds are not seen, in the southern region of our country, people are good at using cormorant fishing, in order to avoid it swallowing fish into the stomach, generally choose to wear a neck sleeve around its neck.

The cormorant has a throat pouch at the front end of the esophagus that can be inflated, and when the cormorant eats the fish, this laryngeal pouch can digest the fish well, and the cormorant can spit out the undigested fish bones, fish scales and other foods in the stomach from the mouth with a mucus sac.

The cormorant is a medium to large seabird that is good at diving and is widely distributed in marine and inland waters around the world, with the warm tropical water Jingyinqiao area being the most.

Cormorants live along the coast, have living areas in inland waters, and often move in small groups, feeding mainly on fish and crustaceans.
