The difference between grass carp and carp

Grass carp, also known as oil carp, grass carp, white carp, black green, etc., inhabit rivers and lakes in plain areas, generally like to live in the middle and lower layers of water and near-shore aquatic grass areas, and carp are also known as carp, carp, etc., often live alone or in small groups in calm and grassy ponds, lakes and rivers. Let's take a look at the difference between grass carp and carp.

The difference of families and genera between grass carp and carp

1. Grass carp: grass carp are freshwater fishes of the family Cyprinidae, Ctenopharyngodon idellus, Ctenopharyngodon idellus, Ctenopharyngodon idellus.

2. Carp: carps belong to the freshwater fishes of the order Cyprinidae, Cyprinidae).

Morphological differences between grass carp and carp

1. Grass carp: the body of grass carp is slightly cylindrical, the head is slightly flat, and the tail is flat. The mouth is curved and needless, and the upper jaw is slightly longer than the lower jaw. The body is light tea yellow, the back is bluish gray, the abdomen is gray, the chest and ventral fins are slightly grayish yellow, the other fins are light gray, and the abdomen is anguless. The head is flat and the tail is flat. The hypopharyngeal teeth are two-line, lateral flattened, comb-shaped, with transverse grooves on the side of the teeth. The dorsal fin and anal fin have no hard thorns, and the dorsal fin is opposite to the ventral fin. The kiss is very short and the length is less than or equal to the diameter of the eye. The length behind the orbit is more than half the length of the head.

2. Carp: carp have a flat body and a round abdomen, with a horseshoe-shaped mouth and 2 pairs. The scales have a cross texture, and the scales are not white after death. There is a flank scale from beginning to end, regardless of the size of the fish has 36 scales, each scale has small black spots. The base of the dorsal fin is longer, and both the dorsal fin and the anal fin have a stout, serrated hard spine. The side of the body is golden, and the lower lobe of the caudal fin is orange-red.

Differences in feeding habits between grass carp and carp

1. Grass carp: grass carp are lively, swim fast, often look for food in groups and are gluttonous. They are typical herbivorous fishes. They feed on zooplankton in fry stage, and on insects, earthworms, algae and duckweed when they are young. When the body length is more than 10 cm, they completely feed on aquatic higher plants, especially Gramineae plants, and the species of plants they eat vary with the food base in the living environment.

2. Carp: carp belong to benthic omnivorous fish, which eat both meat and meat. The bait spectrum is extensive, the kissing bone is well developed, and the food is often ingested by mud. There are throat teeth in the depths of the mouth, which are used to grind food. Omnivorous, digging for food often muddy the water and increase turbidity, which has adverse effects on many animals and plants. Winter goes into hibernation, sinking at the bottom of the river and not eating anything.

Differences in habits between grass carp and carp

1. Grass carp: grass carp generally like to inhabit the middle, lower and nearshore aquatic grass areas in rivers, lakes and other waters. With the habit of migrating rivers and lakes, sexually mature individuals lay eggs in rivers and reservoirs, and after spawning, parent fish and young fish enter tributaries and lakes, usually feeding and fattening in flooded shoal grasslands and flooded areas as well as water bodies attached to trunk and tributaries (lakes, streams, harbours, etc.).

2. Carp: although the carp belongs to benthic fish, this does not mean that its active area remains unchanged. Seasonal changes, cold and warm water temperature, wind direction, air pressure, Shuowang change, clear and turbid water quality, water flow size, water level fluctuation, water dissolved oxygen, bait environment and so on will change the activity area of carp at any time, so that the position of carp can be moved to a large extent.
