CATDOLL : CATDOLL: How much does it cost to raise freshwater fish on ten acres of land?

1. How much does it cost to raise freshwater fish on ten acres of land?

Common freshwater fish, such as the four major carps, cost 50,000 to 60,000 yuan for the average stocking density, including the feeding machine and oxygen generator. If it is a famous and special fish, the same price will cost 90,000 to 100,000 yuan.

Reasonable stocking density should be determined according to the breeding method, technical level, water exchange conditions and feed supply. The stocking density used in various places should be adapted to local conditions according to the pond conditions. For farmers who use 80:20 pond fish farming technology for the first time, the weight of the main fish harvested per acre of water surface shall not exceed the following limits:

a. In ponds with limited oxygenation and no flushing, the fish weight is set at 167 kg;

b. In ponds with unlimited aeration and limited flushing, the fish weight is set at 267 kg;

c. In ponds where aeration and flushing are not restricted, the fish weight is set at 400 kg;

d. Together with 20% of the weight of the stocked fish, the total fish production weight of ponds a, b, and c is 209 kg, 333 kg, and 400 kg respectively.

e. If the average size of fish out of the pond is expected to be 500 grams, the total number of fish stocked in ponds a, b and c is 418, 666 and 800 respectively, of which 80% are main fish and 20% are supplementary fish.

For warm-water fish farming, the general water temperature is 15_30℃, such as carp, grass carp, silver carp, bighead carp, crucian carp and bighead bream; for cold-water freshwater fish farming: the general suitable temperature is 10_20℃, such as rainbow trout and silver carp; for hot-water fish farming: the general suitable temperature is 18_30℃, such as tilapia and freshwater silver pomfret.

2. The breeding cost is very high.

Circular farming can promote the ecological development of agriculture, achieve the goal of tapping potential, reducing consumption and pollution, and is conducive to protecting the ecological environment. For example, the "chicken-pig-maggot-chicken, pig" model is to feed pigs with chicken manure, and then use pig manure to raise maggots to fertilize the fields. Maggots are made into flour, which contains up to 63% protein and is used to feed chickens or pigs. The feeding effect is the same as bean cake. More importantly, maggots contain chitin and antimicrobial peptides, which can greatly improve the disease resistance of pigs and chickens. This model not only saves feed grain and daily drug input, but also makes chicken manure harmless, with obvious economic and environmental benefits. Similar to this is the "chicken--fish, lotus root" model: chickens are raised on the racks, fish ponds are placed under the racks, fish are raised in the ponds, and lotus roots are planted; the "waterfowl--aquatic products--aquatic feed" model: geese and ducks are raised on the water in the dam, fish and shrimps are raised underwater, duckweed is raised in the water, and pigs and chickens can also be raised on the dam; there are also "pig--swamp--fruit (forest, grass, vegetables, fish)" and other models, which are all very good circular breeding models. The cost is relatively high

3. What are the main costs and risks of farming?

Breeding costs:

Ethics, it depends on what species you raise. The cost is generally divided into three stages: commissioning, production (breeding process), and sales. The initial investment alone is divided into many categories. The costs of aquaculture on land and in water vary, and the various costs corresponding to different species are also different. Breeding seedlings (raw materials) requires site selection, site maintenance, environmental sanitation, various handling fees, etc. In the production process, there are feeding costs (raw materials), disease prevention measures, etc. Finally, in the sales process, there will also be market costs, taxes, etc.

4. How much investment is needed to farm fish and loaches? If it is farmed on a small area, how much will it cost?

It depends on the size of the fish and loaches you raise. If you want about 150 loaches per pound, it will cost about 16,000 to 17,000 yuan.

5. How to calculate the cost of sea bass farming

Seedling cost + feed cost (based on the fish's bait coefficient) + cage depreciation + management fee = breeding cost. I hope you can adopt it, thank you
