Common carp

General information

The Common carp (Cyprinus carpio) is a freshwater fish species in the family Cyprinidae. It is native to Asia and Europe but has been introduced worldwide. It is a popular food fish as well as a game fish and is often kept in aquaculture and ornamental ponds. 
The Common carp has a deep, laterally compressed body with large scales. Its coloration can vary from a dark olive-green to a golden-yellow or even a light silvery color depending on the strain or variety. The species typically grows to a length of 40-80 cm, although they can reach up to 120 cm in length and weigh over 40 kg.

The Common carp is an omnivore and its diet consists of both plant and animal matter. They primarily feed on algae, detritus, and small aquatic invertebrates but will also consume small fish and fish eggs if available.

Males and females can be distinguished by their genital papilla. During the breeding season, males develop small white bumps on their pectoral fins and head.

The Common carp reaches sexual maturity at 3-4 years of age. They are known for their ability to reproduce quickly and in large numbers. The breeding season usually occurs in the spring when the water temperature is between 18-24°C. The females can lay up to 300,000 eggs in a single spawning and will often lay their eggs on submerged vegetation or a prepared substrate.

The Common carp can be susceptible to a variety of diseases including bacterial infections, parasitic infestations, and fungal diseases.

The Common carp is native to Asia and Europe but has been introduced to many parts of the world for aquaculture and sport fishing purposes.

The Common carp is considered an invasive species in some areas due to its ability to reproduce and outcompete native species rapidly.

The Common carp should be acclimated slowly to avoid shock. It is recommended to place the fish in a bag with water from the aquarium for 15-20 minutes before releasing it into the tank.
