What is the method for calculating the cost and profit of grass carp farming?

The cost of raising 1 mu of grass carp is about 500 yuan, and the output can reach about 500 catties, which can be sold at about 5 yuan per catty, so the income from grass carp is about 2,500 yuan. After deducting the cost of raising grass carp, the profit is about 2,000 yuan. Grass carp is an important freshwater farmed fish in my country. Together with silver carp, bighead carp and black carp, it constitutes the four major carps in my country.

1. The cost of breeding grass carp

1. Fish species cost

Grass carp is generally raised in mixed culture, mainly grass carp, and then mixed with appropriate amounts of silver carp, bighead carp and other fish species. Generally, one acre of pond can raise 30 kilograms of silver carp, 3 kilograms of bighead carp, 60 kilograms of grass carp and an appropriate amount of bream, etc., and the cost of fish species is about 500 yuan.

2. Feed costs

Generally, one mu of fish pond needs to be fed about 760 kilograms of feed each year, with a total cost of about 1,300 yuan.

3. Other costs

It mainly includes various miscellaneous expenses such as fertilizers, medicines, water and electricity, which require a total of about 2,100 yuan.

4. Total cost

Therefore, a 10-acre fish pond will require an investment of about 20,000 yuan.

2. Profits of Grass Carp Farming

1. Calculated based on one mu of fish pond, the output of one mu of fish pond is generally about 8,000 jin, including 300 jin of silver carp, 500 jin of grass carp, and about 100 jin of bream. The prices of these fish are different. Generally, the price of silver carp is about 3 yuan/jin, and the gross income is 900 yuan.

2. The price of bream is 4.5 yuan/jin, and the gross income is 450 yuan. The price of grass carp is relatively expensive, about 5 yuan/jin, so the gross income of grass carp can reach 2,500 yuan. Adding them all up, the gross income of one acre of pond is 3,800. Excluding the breeding cost, the net income of one acre of pond can reach 2,700 yuan, so the profit of a 10-acre pond is about 27,000 yuan.

Is bream a freshwater fish or a saltwater fish? Can it be farmed?

Bream is a freshwater fish, not a marine fish. It can only adapt to the environment in freshwater and will die in seawater due to inadaptability. Specifically, bream is mainly distributed in the Yangtze River Basin in my country, and is also found in the Qiantang River, Pearl River and other basins. Bream likes to live in the middle and lower layers of freshwater, especially in winter, and is basically at the bottom. In waters with a lot of silt at the bottom, rich plants and slow water flow, there are often many breams. 1. Is bream a freshwater fish or a marine fish? Freshwater fish and marine fish are the classification of all fish species, based on their living habits and living environment. From this perspective, bream is a freshwater fish. They live in my country's freshwater basins and can adapt to life there. They are not marine fish and cannot adapt to the marine environment. They will not adapt to the seawater and may die quickly due to inadaptability. Specifically, the main distribution basin of bream in my country is the Yangtze River, and the number of them in the middle and lower reaches is relatively large. In addition, there are also many breams in some affiliated lakes. In addition to the Yangtze River, there are also breams in the Qiantang River, Pearl River and other basins.

Bream likes to live in the middle and lower layers of freshwater basins, especially the bottom layer, where there are more bream. When winter comes, bream will basically spend the winter at the bottom of the water. They like to stay in places with more silt and places with lush aquatic plants, because they are a herbivorous fish species, and their main food is various aquatic plants in the water and plant debris nearby. In addition, bream also has requirements for the flow rate of fresh water. They generally live in places with slower flow rates. There are more bream in still water, and they are rare in places with fast flow rates.

2. Can bream be farmed? As mentioned above, bream is a freshwater fish species. In addition, bream is also a fish species that can be artificially raised. In fact, it is quite common to farm them in real life, and they are one of the representative farmed fish species in my country. Many breeders choose to farm them because of their high edible and nutritional value, and farming them can bring higher economic benefits. Since bream itself is a freshwater fish species, freshwater farming methods are also required for artificial breeding. In the case of large-scale breeding, breeding ponds are basically required, and they need to be built in places with abundant freshwater sources.
