CATDOLL : CATDOLL:What kind of grass do silver carp eat?

1. What kind of grass does silver carp eat?

Silver carp is a filter-feeding fish that eats phytoplankton but not grass. Silver carp feeds on plankton throughout its life. In the fry stage, it mainly eats zooplankton, and gradually switches to eating phytoplankton when it is more than 1.5 cm long. It also likes to eat grass carp feces and chicken and cow dung, as well as soy milk, bean dregs powder, bran and rice bran, and prefers to eat artificial micro-granular compound feed.

Growth and reproduction

Silver carp grows fast and has high yield. Silver carp reaches sexual maturity 1-2 years earlier than grass carp. Mature individuals are also smaller, and female fish weighing more than 3 kg can generally reach maturity. Female fish weighing about 5 kg can carry about 40,000 to 50,000 eggs per kg of body weight. They spawn in April and May every year, and can carry 200,000 to 250,000 eggs.

The eggs are buoyant, and the spawning period is similar to that of grass carp. In ponds, if there is sufficient bait, the fish can grow to 500-800 grams in the first year, and the weight of three-year-old fish can reach 3-4 kilograms. In natural rivers, it can weigh 30-40 kilograms.

The nutritional components of silver carp muscle vary with body length and season, and the range is: water content 60.3-80.9%, protein 15.3-18.6%, fat 2.0-20.8%, ash 1.0-1.4%, and nitrogen-free extract 0.2-1.7%.

The biochemical composition of fish muscles also changes with the growth and development of the fish. When the water content gradually decreases, the protein and fat gradually increase.

Pond breeding

1. Fish breeding

Stocking of fish fry: In mid-to-late May, when the water temperature in the pond is stable above 18°C, it is the appropriate time to stock. Stock silver carp and black carp at a density of 3-5 per square meter.

Feeding and management: After the fry are put into the pond, they mainly filter-feed on planktonic plants and animals and also eat feed debris.

Adult fish farming: fish stocking specifications and density, the wintering fish stocking specifications are 100-200 grams/tail, stocking density is 0.4-0.5 tail/O. Silver carp is a fish stocking with ants, the time of catching carp out of the pond shall prevail.

2. Winter management

Overwintering density: The overwintering density of mature fish and fingerlings in ponds is generally 0.3-0.6K/O. It can be adjusted appropriately according to pond conditions.

It is a typical filter-feeding fish. Main food: Silver carp feeds on plankton throughout its life. In the fry stage, it mainly eats zooplankton. When it grows to more than 1.5 cm, it gradually turns to eating phytoplankton. It also likes to eat grass carp feces and chicken and cow dung. It also eats soy milk, bean dregs powder, bran and rice bran, and prefers to eat artificial micro-granular compound feed. It is very interested in sour food and has a good appetite for rotten food. Silver carp's food has obvious seasonality. In spring and autumn, in addition to plankton, it also eats a lot of rotten bait; the lower the water level in summer, the greater its food intake; in winter, it eats less and moves less. It is suitable for breeding in fertile water. The length of the intestinal tube is about 6-10 times the body length.

Appetite is proportional to water temperature. Silver carp likes high temperature, and the most suitable water temperature is 23℃~32℃. In the hot summer, silver carp has the strongest appetite. July to August in the north is a good time to fish for silver carp. After the autumnal equinox, the weather gradually cools down, and the appetite of silver carp decreases, making it difficult to catch them.

It is very interested in sour food and has a good appetite for rotten food. Silver carp's food has obvious seasonality. In addition to plankton in spring and autumn, it also eats a lot of detritus bait; the lower the water level in summer, the greater its food intake; in winter, it eats less and moves less during the winter. It is suitable for breeding in fertile water. The length of the intestine is about 6-10 times the body length.
