Crucian The Crucian Carp is the only member of the genus Cyprinus in its family (Cyprinidae) and not to be confused with any other Cyprinids. The big head, thin tail and forked tail fin are characteristics of cyprinids, but crucians have 32-34 scales along the lateral line whereas other cyprinids have fewer scales. Crucians are slow swimmers, tending to shoal in the upper half of the water column. They are benthic feeders, mostly eating plants but also enjoying small invertebrates, filamentous algae and detritus. One other major difference between crucians and other members of their family is the fact that most species of cyprinids are diurnal, preferring to feed at day time. Crucian Carp is nocturnal, most active between midnight and dawn with its activity peaking at around 3 am, which may explain why most people don't see them very often.
As their name suggests these fish tend to be found in the most shallow of waters, often hugging the bottom for camouflage. They are quite often found in canals and ditches with sandy or muddy bottoms where they find most of their food. But, they also live in lakes, ponds, reservoirs, and slow-flowing rivers with poor vegetation cover.
Crucian Carp are not picky about their food. If they can catch it they will eat it, which is why they are often caught with other larger fish that are better equipped to take down faster or more elusive prey items. Crucian Carp feed on benthic organisms such as aquatic insects, molluscs, and small crustaceans, filamentous algae (especially when their preferred food is scarce), detritus, small fish, and plant material. They are not fussy eaters but they cannot swallow large pieces of food whole like some members of the minnow family do, e.g. Chub Minnow or Gudgeon. To compensate for that Crucian Carp will use their lower pharyngeal bone to crush larger pieces of food so they can be swallowed.
Crucian Carp spawning activity peaks when the water reaches 10°C in March and when it reaches 15°C in April to May, but breeding takes place throughout the year with no distinct peak. Spawning is initiated by the male who will chase the female and perform a series of ritual displays before the eggs are laid. He will then guard the area where the eggs have been fertilized by fanning them with his fins until they hatch after 2-3 days.
The Crucian Carp is found in Europe from Britain in the west to Russia in the east, surrounding an area that includes both temperate and subarctic habitats. It is a well-established invasive species in North American waters where it has been present since the 1940s, but it's native to western Asia as well as parts of northern Africa.
Global crucian production
Crucian carp is a freshwater fish belonging to the family Cyprinidae. It is native to Europe and Asia but has been introduced to many other parts of the world. The crucian carp is a popular game fish and is also raised for food in many parts of the world.
The crucian carp is a medium-sized fish, growing to a maximum length of about 1 meter (3.3 feet). It is greenish-brown in color with dark spots on the body. The crucian carp is found in lakes, ponds, and rivers across Europe and Asia. It has been introduced to many other parts of the world, including North America and Australia.
The crucian carp is a popular game fish. It is also raised for food in many parts of the world. The fish is harvested from the wild and also raised in fish farms. The flesh of the crucian carp is white and delicate, with a mild flavor. It is often used in European and Asian cuisine.
The crucian carp is an important fish in many cultures. In China, the fish is considered to be a symbol of good luck and is often given as a gift. In Europe, the crucian carp is a traditional Christmas dish in some countries. The crucian carp is a hardy fish and can live for up to 15 years in the wild. However, the average lifespan of the fish is only 4 to 5 years.
