CATDOLL : CATDOLL: Can silver carp and bighead carp reproduce naturally? Do they have high water quality requirements?

1. Can silver carp and bighead carp reproduce naturally? Do they have high requirements for water quality?

Silver carp and bighead carp can reproduce naturally in a specific flowing water environment; in still water (including reservoirs), silver carp and bighead carp cannot reproduce naturally. At this time, because the gonadal development of silver carp and bighead carp must be stimulated by the flowing water environment, and the fish eggs laid are floating, they need to develop in a specific flowing water environment. Silver carp and bighead carp have high requirements for water quality and oxygen content in the water. They are not tolerant to lack of oxygen in the water. They will float immediately if there is lack of oxygen in the water, and some will die soon. Too rich or too thin water is not good for the growth of silver carp and bighead carp. If the water quality is too rich, water should be added or changed in time. If the water quality is too thin, organic fertilizer should be applied in time.

1. Can silver carp and bighead carp reproduce naturally?

1. Silver carp and bighead carp can reproduce naturally, but only in a specific flowing water environment. They cannot reproduce naturally in still water (including reservoirs). The gonadal development of silver carp and bighead carp must be stimulated by flowing water. At the same time, the eggs they lay are floating, so they need a specific flowing water environment to develop. Silver carp and bighead carp generally reach sexual maturity and start spawning when they are about 4 years old.

2. Except for artificially released fry, it can be said that in most waters, one less fish is caught for every one you catch. Even in most waters open to fishing, silver carp and bighead carp are the main economic fish species farmed and are responsible for water purification. Therefore, fishing for silver carp and bighead carp is prohibited in many waters.

2. Do silver carp and bighead carp have high requirements for water quality?

1. Silver carp and bighead carp have high requirements for water quality. Pay attention to keeping the water clean and prevent water quality from deteriorating. They have poor tolerance to hypoxia. They will float to the surface immediately when there is a lack of oxygen in the water, and some will die soon. Silver carp and bighead carp like fertile water, but too fertile or too thin water is not good for their growth. If the water is too fertile, add water or change the water in time. If the water is too thin, apply organic fertilizer in time. The diseased pond should be filled with clean water in time to improve the water quality, or the diseased fish should be transferred to a pond with fresh and clean water.

2. Silver carp and bighead carp are typical filter-feeding fish. They like high temperature and cannot tolerate hypoxia. They have high requirements for oxygen content in water. When the oxygen content is low, silver carp and bighead carp will react first and will float on the water surface in groups to resist hypoxia. They usually live in shallow water areas of the water layer, like to swim and forage in the upper and middle waters, and especially like high temperature or relatively high water temperature waters.

Silver carp and bighead carp can reproduce naturally in a specific flowing water environment; in still water (including the Jifan Reservoir), silver carp and bighead carp cannot reproduce naturally. At this time, because the gonadal development of silver carp and bighead carp must be stimulated by the flowing water environment, and the fish eggs laid are floating, they need to develop in a specific flowing water environment. Silver carp and bighead carp have high requirements for water quality and oxygen content in the water. They are not tolerant to lack of oxygen in the water.

2. Growth and reproduction of silver carp

Silver carp grows fast and has a high yield. The age of sexual maturity of silver carp is 1-2 years earlier than that of 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 have a relative egg-bearing capacity of about 40,000 to 50,000 eggs per kilogram of body weight. They spawn from April to May every year, and have an absolute egg-bearing capacity of 200,000 to 250,000 eggs per mu. The eggs are buoyant. The spawning period is similar to that of grass carp. Under pond conditions, if there is sufficient bait, the fish can grow to 500-800 grams in the same year, and the weight of three-year-old fish can reach 3-4 kilograms. In natural rivers, they can weigh up to 30-40 kilograms. Qiao Sou Sen

3. Will silver carp give birth?

Silver carp will lay eggs, but only in places with flowing water such as rivers. Even if they reach sexual maturity in ponds, they will not lay eggs or reproduce. (Unless they have been artificially treated)
