What should we pay attention to when breeding freshwater silver pomfret?

Freshwater silver pomfret has a varied diet and can consume a variety of aquatic and terrestrial plants, small fish and shrimp, organic debris, wheat bran, bean cake and other agricultural and sideline products. However, in order to improve the utilization rate of feed and the input-output ratio, freshwater silver pomfret should be fed with sinking granular feed when mixed with other fish. It should be fed 4 times a day, 40% in the morning and 60% in the afternoon. The daily feeding amount is 5% to 7% of the fish body weight. If the water temperature is low, the feeding amount can be appropriately reduced. When mixed with shrimp, no bait is needed.

In aquaculture, water quality management should be strengthened to maintain a good water environment. Regular disinfection and the use of water quality improvers such as zeolite powder should be adhered to to reduce excessive organic suspended matter in the water. Freshwater silver pomfret has strong disease resistance and rarely suffers from diseases when aquacultured in saline-alkali water. However, attention should also be paid to fish disease prevention and control, especially strengthening the disinfection of fish species to avoid bringing diseases and parasites into the aquaculture pond.

Mixed stocking of freshwater fish is to stock different types of fish in the pond according to their different habitats and ______.

The four major carps refer to the artificially raised black carp, grass carp, silver carp and bighead carp. They are the fish species selected for mixed culture and high yield in pond fish farming in China for more than 1,000 years. Silver carp is also called silver carp. It moves in the upper layer of the water and eats phytoplankton such as green algae; bighead carp has a larger head and is commonly known as "fat-headed fish", also called silver carp. It lives in the middle and upper layers of the water and eats protozoa, water fleas and other zooplankton; grass carp lives in the middle and lower layers of the water and feeds on aquatic plants; black carp lives in the bottom of the water and eats mollusks such as snails, clams and mussels; according to the different water layers and feeding habits of bighead carp, silver carp, grass carp, black carp, crucian carp, etc., they are mixed and raised in one pond, which is called mixed stocking. Mixed stocking can not only make full use of the three-dimensional space of the pond water, comprehensively and reasonably utilize various natural baits, and improve the utilization rate of artificial feed, but also give play to the mutual beneficial effects between different fish, maintain a favorable ecological environment, provide a variety of commercial fish, and achieve the goal of high yield.

Mixed breeding of these four types of fish can improve the utilization rate of bait and increase fish production.

Therefore, the answer is: diet; three-dimensional space; natural bait.
