Four key points for fish farming at the start of spring
1. Fertilization: In early spring, when the pond water temperature stabilizes at 8°C to 10°C, start applying additional fertilizer to cultivate natural food organisms in the water. The amount of fertilizer should be determined based on the fertility of the water and the quality of the fertilizer. Generally, apply 60 to 90 kg of human and animal manure per mu, or 100 to 150 kg of livestock manure. If chemical fertilizer is used, follow a nitrogen-to-phosphorus-to-potassium ratio of 1:1:0.5. When applying, first crush it, mix it with water, and splash it evenly over the entire pond. The total amount per mu is 3 to 7 kg, with each application spaced 5 to 10 days apart.

Practical methods for rejuvenating weak fish fry in autumn
Due to the hot summer climate, aging water quality, and feeding management issues, many farmers' fish fry are in poor condition. If these weak fish fry are not rejuvenated promptly when the autumn weather turns clear and cool, it will not only be detrimental to their overwintering but will also greatly affect next year's production. Therefore, doing a good job of autumn rejuvenation of weak fish fry is very important. The methods for autumn rejuvenation of weak fish fry are introduced as follows: transferring ponds and clearing ponds. After the high-temperature seasons of spring and summer, water quality generally ages, natural organisms decrease, and harmful pathogens increase, which is extremely unfavorable for fish

Integrated fish-and-goose farming model boosts farmers' income by 30 percent
Mixed farming of fish and geese is, for fishermen, a scientific farming model with "ten benefits and not a single drawback." This model makes full use of water surface and land resources, and under the same conditions increases economic returns by up to 30% compared with raising fish or geese alone, making it an effective new path to prosperity for fishermen. Advantages of integrated fish-and-goose farming: geese are fully automatic, energy-saving and highly efficient aerators for fish ponds. When fish and geese are raised together, farmers need not worry about oxygen depletion in the water caused by weather changes, because in low-pressure weather geese will rush to jump into the water, bathe and chase each other, churning up the water

Autumn and winter nourishment is not the same as fish and meat medicinal diets
Autumn and winter nourishment ≠ fish and meat medicinal diets! Chinese people have had the custom of nourishing the body in autumn and winter since ancient times. With social development and rising living standards, autumn and winter nourishment is no longer simply equated with ginseng plus astragalus, and the way of nourishing should change. A balanced diet is the foundation. We all know that protein, carbohydrates, fat, vitamins and minerals are all nutrients the human body needs. However, many people's daily diets are very unbalanced, with unreasonable combinations of meat and vegetables, too little grains and coarse grains, and too much meat. Combined with a lack of exercise, this has led to steadily rising incidence rates of high blood pressure, diabetes and obesity.

Precautions for Spring Transport and Stocking of Fish Fry
Spring returns to the earth, water temperatures gradually rise, and it is once again the best time of year for transporting aquatic fry and fingerlings. During this period, because water temperatures are relatively low, fish are less active, and at the same time their bodies are firm and scales tight, so they are less likely to be injured during transport, which can increase the survival rate of spring stocking of fingerlings. There are many precautions in the spring transport and spring stocking of fingerlings, and fishermen friends are reminded to pay attention to them. 1. Pond disinfection should be carried out after removing excess sludge from the pond, reinforcing the pond embankment, and clearing the inlet and drainage ditches. Generally, for a dry pond, use about 200kg of quicklime per mu, slake it into a slurry, and

The Harm of Rotifers to Adult Fish and Control Methods
In recent years, while providing technical services, the author has found that rotifers are overrunning adult fish ponds in some areas, causing many problems for farmers. This phenomenon is especially serious in some long-established aquaculture areas or places using sewage for aquaculture, and it deserves sufficient attention. The harm of rotifers to adult fish The harm of rotifers to adult fish is mainly as follows: rotifers have an extremely strong reproductive rate and will form a dominant population in a short time, eating most of the algae, reducing photosynthesis and weakening oxygen production capacity. At the same time, they also consume a large amount of oxygen, and the result is very likely to cause fish oxygen

Comprehensive prevention and control measures are needed for fish hepatobiliary syndrome
In recent years, with the continuous increase in the intensification of aquaculture, the incidence of fish hepatobiliary syndrome has been rising. Hepatobiliary syndrome can occur in various cultured fish, most notably in common carp and grass carp, and generally the incidence is high in adult fish. There are many causes of fish hepatobiliary syndrome, which can be summarized mainly in the following aspects. (1) Pathogenic microorganism infection. Infections by pathogenic microorganisms such as Aeromonas hydrophila, Edwardsiella, and rhabdovirus and reovirus can directly or indirectly cause hepatitis in fish. Pathogenic microorganisms
