What food does black carp mainly eat?

Black carp prefers to eat underwater creatures, such as snails, clams, cockles, and clams. They also prey on small shrimps, insect larvae, and some zooplankton. If it is artificially fed, you can mix 5% silkworm pupae, 5% fish meal, 40% green hay, 30% cotton cake, 10% bean cake, and 5% wheat, and then feed it to the black carp. You can also grind snails and river clams to feed the black carp.

What kind of grass do black carp eat?

Herrings eat Sudan grass. Sudan grass (Sorghum sudanense (Piper) Stapf.) is an annual herbaceous plant of the genus Sorghum in the Poaceae family. It has fibrous roots and a well-developed root system that penetrates deep into the soil, up to 2.5 meters. The stem is upright, cylindrical, 2 to 3 meters high, and 0.8 to 2.0 cm thick. It has strong tillering ability and many side branches, usually 15 to 25 per plant, and up to 40 to 100. There are 7 to 8 leaves, which are broadly linear, 60 cm long, 4 cm wide, dark green, and smooth on the surface; the leaf sheaths are slightly long, fully ensheathed, and have no ear. The panicle inflorescence is relatively loose, with slender branches, and each node has two spikelets, one sessile, a bisexual flower that can bear fruit; the other stalked, a male flower that does not bear fruit. The fruiting spikelets have thick and shiny lemmas. The caryopsis is flat and oval, and the seeds are completely covered by inner and outer palea. The seed color varies from yellow, purple, or black depending on the variety, and the thousand-grain weight is 10 to 15 grams.

The diet of black carp is relatively simple, with snails and clams as the main food. Young fish cultured in ponds prefer to eat grain feed, but when they grow to 15 cm in length, the crushing function of the pharyngeal teeth is enhanced, and their diet changes.

Grass carp is often used as the main stocking object in pond culture and lakes, reservoirs and rivers because of its simple diet, wide source of bait, rapid growth and high yield. Since the success of artificial induction of spawning and fertilization and hatching technology in 1958, the source of fry and fish species is easy, and it has become the main intensive breeding object in my country. Grass carp is also used by fishermen to stock it outside for one or two years to open up wasteland and weed because it can remove grass in water bodies and along the coast. Grass carp is called "pioneer" because it can quickly remove various grasses in water bodies. In the late Tang Dynasty in Guangdong, there are records of building ridges on wasteland, irrigating with rainwater, and stocking grass carp for one or two years to remove weeds and make the fields mature. Grass carp is often mixed with silver carp and bighead carp. Grass carp is fed with green grass, and the feed left in the water and the waste discharged by grass carp are used to cultivate plankton as feed for silver carp and bighead carp.

Grass carp is widely distributed in the plains from Guangdong to the northeast of my country, except Xinjiang and the Qinghai-Tibet Plateau. Since the successful artificial induction of fertilization and hatching in 1958, it has been transplanted to many countries in Asia, Europe, America and Africa.

Grass carp (Ctenopharyngodon idellus) belongs to the genus Ctenopharyngodon, subfamily Leucophideae, family Cyprinidae, order Cypriniformes. Common names for grass carp include: grass carp, oily grass carp, grass carp, white grass carp, grass carp, grass root (northeastern), mixed fish, black herring, etc. English name: Grass carp.

The only species of the genus Grass Carp in the subfamily Leucophaga of the family Cyprinidae in the order Cypriniformes. Also known as white carp, grass root fish, and thick fish. The body is slightly cylindrical, with a slightly flat head and a laterally flattened tail; the mouth is arc-shaped and has no whiskers; the upper jaw is slightly longer than the lower jaw; the body is light tea yellow, the back is blue-gray, the abdomen is grayish white, the pectoral and pelvic fins are slightly grayish yellow, and the other fins are light gray (see picture). It is a fish endemic to the plains from Guangxi to Heilongjiang in eastern China.

It inhabits rivers and lakes in plain areas, and generally prefers to live in the middle and lower layers of water and near the shore with abundant aquatic plants. It is lively, swims quickly, and often forages in groups. It is a typical herbivorous fish. It hibernates in the main stream or deep water of lakes. Parent fish have the habit of upstream migration during the reproductive season. It has been transplanted to many countries in Asia, Europe, America, and Africa. Because of its rapid growth and wide source of feed, it is one of the four major freshwater fishes in China.

Among the important freshwater economic fishes in my country, the most famous ones are the world-famous "four major carps", such as grass carp (Ctenopharyngodon idellus), black carp (Mylopharyngodon piceus), silver carp (Hypophthalmictuthys molitrix), and bighead carp (Aristichthys nobilis). Although they are all endemic to my country, grass carp is regarded as a pioneer and transplanted to all parts of the world for its unique feeding habits and foraging methods. Its body is relatively long, slightly cylindrical, and its abdomen has no ridges. Its head is flat and its tail is laterally flattened. Its mouth is terminal, arc-shaped, and has no whiskers. There are two rows of hypopharyngeal teeth, which are laterally flattened and comb-shaped, with transverse grooves on the sides of the teeth. There are no hard spines on the dorsal and anal fins, and the dorsal and pelvic fins are opposite. Its body is tea yellow, its back is blue-gray with a slight grass green, and its even fins are slightly yellow.

Herring can be braised, dry-roasted, stewed, sweet and sour, or cut into pieces and smoked. It can also be processed into strips, slices, or chunks to make a variety of dishes.

2. Tips for cleaning black carp: Hold the knife in your right hand and hold the fish's head with your left hand. Scrape off the scales from the tail to the head with the knife. Then use your right thumb and index finger to dig out the fish's gills. Use scissors to cut open the black carp's abdomen from its mouth to the navel, dig out the internal organs, rinse them with water, scrape the black film on the abdomen with a knife, and rinse them clean.

Herring Recipe

Grilled Herring

Ingredients: middle section of herring (1 section, 600g), ham (45g), glutinous rice (160g), whole onion (2 stalks), ginger (3 slices), rice wine (75g), salt (20g), MSG (a little)

Preparation: 1. Kill a whole herring, clean it, wash it, cut it in half, leaving a 600-gram middle section, and use a slanted knife to evenly cut 10 slanted seams on the front, without cutting through each slanted seam. Apply salt and marinate for half an hour; mix the fragrant lees and wine, and put the fish in the lees for about three hours to make it taste good. Then take it out and wash it with cold water.

2. Slice the ham into 10 2-inch long slices, insert one slice into each diagonal seam on the fish, place on a long plate, add onion, ginger, salt and MSG, steam for about ten to fifteen minutes, remove the onion and ginger, and if you like onion and ginger, put some shredded onion and ginger on top, then drizzle a little cooked lard on top.

Black carp lives in the lower layer of the water, feeding on snails, clams, young clams as their main food, and also eats shrimps and aquatic insects. Multiflora ryegrass, alfalfa; Sudan grass, hybrid wolf, black carp is an omnivorous fish, it is easy to raise when it is a little bigger, if you want it to grow fast, feed it more meat! Water insects and small snails will grow very fast!

Feeds mainly on snails, clams, and young clams, and also eats shrimp and aquatic insects.
