Bream breeding methods and techniques

Bream grows quickly, has strong adaptability and a wide range of diet. It is a freshwater herbivorous fish that can grow to as large as seven or eight kilograms. It is mainly distributed in medium-sized lakes in the middle and lower reaches of the Yangtze River in China. Below, I will introduce the methods and techniques of bream farming . Let’s take a look.

1. Pond selection

It is generally recommended to raise bream in a live pond that can take in and drain water, and the water source must be clean and sufficient. The size of the fish pond should be more than two acres, with a water depth of 1.5 meters to 3 meters. The bottom of the pond should be exposed to the sun and cracked in winter, and there should not be too much silt in the pond. The most important thing is not to discharge sewage into the pond. Ten days before releasing water into the pond, the pond should be disinfected by spraying quicklime . Use 50 kilograms of quicklime per acre. After ten days of exposure to the sun, the water can be drained into the pond.

2. Stocking of fish fry

Choose small fish fry with no wounds on the surface, good growth, strong physique and plump body. Control the size to about 8-225px, soak it in salt water or potassium permanganate solution before putting it into the pond. When breeding bream, it is not necessary to breed only bream in the pond. A small amount of bighead carp, crucian carp, etc. can be raised together for mixed breeding. Generally, the stocking density in one acre of pond is about 1,200 fish, and about 100 bighead carp and 300 crucian carp are added.

3. Water quality management

The water quality requirements for bream farming are relatively high. The water transparency should be maintained at 25-30 cm and the water pH value should be between 7.6-8.5. The peak growth season for bream is between June and September. Pay attention to changing the water, observe weather changes, and correctly install the aerator equipment. If you encounter rainy, windless, and sultry weather, you should turn on the oxygenator every morning. When you get up in the morning, you should check the fish's mood. If you find that the fish are floating on the surface and lack of oxygen, you should add water and turn on the oxygenator in time.

4. Feeding management

During the entire bream farming process, special granular feed is selected, and compound feed with corresponding particle size is selected for feeding according to individual size and nutritional needs. In the early stage of breeding, feed fish fingerlings at a daily feeding amount of 4-5% of the fish body weight. In the middle and late stages of breeding, feed adult fish at a daily feeding amount of 3-5% of the fish body weight, and feed three times a day. When feeding, you must master the "four determination" principles: timing, positioning, quality, and quantity. During the feeding period, mix the feed with EM bacteria every month, mix 1 kg of EM bacteria for every 10 kg of feed, and feed it after three hours of fermentation. Do this for a week. The treated feed can strengthen the fish's stomach and intestines, improve feed conversion rate, and some residual feed can be organically decomposed, thereby reducing pond pollution. The daily feeding amount should also be flexibly adjusted according to water temperature, weather, and fish feeding intensity.

5. Daily management

Patrol the pond once in the morning and evening every day, and adjust the feeding amount in time according to the fish's activity, feeding, and growth. Regularly check the water temperature, transparency, dissolved oxygen, pH, and ammonia nitrogen content. If the water quality is found to be deteriorating, timely improvement and adjustment measures should be taken to keep the pool water tender green or tea green. Pay attention to check the operation of the aerator, bait thrower, and water pump. If any fault is found, it should be repaired or replaced in time. Keep good pond records at ordinary times, record weather, water temperature, water quality, fish stocking, feeding, pesticide application, fishing and sales, so as to summarize breeding experience and improve breeding level.

The above are the methods and techniques for bream farming. Bream has strong disease resistance, but prevention is still the main approach. Cleaning the pond and disinfecting the fry before stocking can effectively reduce the incidence of fish diseases.
