CATDOLL : CATDOLL: In which month do silver carp grow fastest? How big can they grow in a year?

Generally, silver carp (bighead carp) grows fastest in summer and autumn when the water temperature is above 26℃, especially in autumn. Under artificial breeding conditions (sufficient feed), the weight of a one-year-old fish is generally around 0.8-1kg, the weight of a two-year-old fish is generally around 2-3kg, the weight of a three-year-old fish is generally around 3-4kg, and the weight of a five-year-old fish is generally around 7-10kg.

1. Which month does silver carp grow fastest?

1. Generally speaking, silver carp (bighead carp) grows fastest in summer and autumn when the water temperature is above 26°C, especially after the beginning of autumn.

2. Silver carp are mostly distributed in the middle and upper layers of freshwater areas. They are warm-water fish, and the suitable water temperature for their growth is 25-30℃. In winter and spring, the water temperature is low, the silver carp's appetite decreases, and its growth rate slows down (in severe winter, they stop eating and hibernate in the riverbed and deep lakes).

3. Silver carp is a filter-feeding animal. Whether in the fry stage or the adult stage, it feeds on zooplankton such as rotifers, cladocerans, copepods, and also eats phytoplankton such as diatoms and cyanobacteria. After the beginning of autumn, the temperature is lower than that in midsummer, the light is suitable, and the temperature difference between day and night is formed, which is conducive to the reproduction and growth of beneficial algae and zooplankton (at 2-3 pm, the water temperature reaches 35℃, which is suitable for the rapid growth of rotifers. In the evening, the water temperature drops to 25℃, which is suitable for the reproduction of rotifers, and the rise and fall of water temperature will stimulate the sexual reproduction of rotifers), thus providing enough food for silver carp.

2. How big can silver carp grow in a year?

1. Silver carp (bighead carp) grows very fast. If it is raised artificially (with sufficient feed), the weight of a one-year-old fish is generally around 0.8-1kg, the weight of a two-year-old fish is generally around 2-3kg, the weight of a three-year-old fish is generally around 3-4kg, and the weight of a five-year-old fish is generally around 7-10kg. The common individual is generally over 10kg. If it is in a natural river, the weight of silver carp can reach about 30-40kg.

2. The fastest weight gain of silver carp is between 3 and 6 years old. After 6 years old, the weight gain rate gradually slows down. The fastest body length gain of silver carp is between 1 and 4 years old. After 4 years old, the body length gain rate gradually slows down.
