The Golden Secret: Why is the Crossfish known as the "Jewel of the North"?
Carassius carassius is a medium-sized freshwater fish belonging to the common carp family and widely distributed in the waters of Northern Europe. This fish is known as the "Jewel of the North" because of its golden appearance. Not only its appearance, but also its ecological characteristics, adaptability and importance in cuisine have given it a place in European culture.
Distribution range
The cross fish has a very wide distribution range. It can be seen from the UK to the Arctic Circle in Russia and Scandinavia, and even as far south as central France and the Black Sea. They usually inhabit lakes, ponds, and slow-moving rivers.
Crossfish is a species native to the UK and is not an introduced species.
Physiological adaptation
Crossfish exhibit amazing physiological adaptability. They are able to survive for a considerable period of time using anaerobic respiration in the completely anoxic environment of winter, which is highly unusual among vertebrates. One of their metabolites is ethanol, which allows crossfish to survive and grow in extremely challenging environments.
In experiments, crossfish can survive in an oxygen-free environment for up to 140 days.
Fishing
In the UK, crossfish are part of recreational or competitive fishing and are included in the category of coarse fish. The record of catching the delicious crucian fish in the UK shows that the largest one weighed four pounds and nine ounces (about 2.08 kilograms). In the Netherlands, some anglers have caught a 54-centimeter crossfish weighing 3 kilograms.
Relationship with goldfish
The goldfish (Carassius auratus) is considered a cultivated species of crossfish, mainly derived from wild crossfish. This makes it even more important to distinguish between true Crossfish and Goldfish hybrids when fishing.
Cooking and Food Culture
The cross fish plays an important role in different cultures. In Poland, for example, they regard crossfish as the most delicious table fish and often cook it with sour cream. It is also part of the rich holiday table and may have a close connection with Jewish culture.
In Russia, cross fish is called "golden cross fish" and is often used to make traditional Russian beetroot soup.
Ecology and Economy
Crossfish are not only important members of pond ecosystems, but also play a role in aquaculture around the world. According to 2008 data, crossfish production reached 1,957,337 tons, worth more than $2.1 billion.
Conclusion
As the "Jewel of the North", the cross fish is undoubtedly a precious creature given to us by nature. Its unique adaptability and historical and cultural significance allow it to play an important role in both biodiversity and culinary culture.
