2. How much does it cost to raise an acre of tilapia?
(1) fry cost: Take an acre as an example. Usually, an acre of fish ponds can keep about 2,000 tilapia fry. Now the price of tilapia fry in the market is about 20 cents, so the input cost of tilapia fry in an acre is in 400 yuan.
(2) Fish pond rent: If you have land resources in the countryside, then the land rent can be ignored. But if you want to rent, then the rent of an acre of fish pond is about 800 yuan.
(3) Feed cost: Generally, tilapia can be caught and marketed when it is cultured to about 1 kg. When tilapia is cultivated, the feed cost for one catty is generally around 3 yuan, so the feed cost for one tilapia is around 6,000 yuan for one acre in 3 yuan.
(4) Labor miscellaneous expenses: The labor management cost of an acre of tilapia is basically negligible, mainly considering various miscellaneous expenses such as water and electricity, oxygen enrichment and medicines. On average, a fish needs to invest about 0. 1 yuan, so the miscellaneous expenses cost of an acre of tilapia is in 200 yuan. According to the above data, we can draw that the cost of raising an acre of tilapia is about 6500 yuan except the rent of fish ponds.
3. How much profit can you earn by raising an acre of tilapia?
Generally, the size of tilapia raised for fishing is about 1 kg. Based on the survival rate of 95%, the final survival of tilapia in one acre is about 1900, so the yield is about 1900 kg. At present, the purchase price of tilapia is about 10 yuan /kg, so the output value of tilapia is about 1 10,000 yuan, so the profit of an acre of tilapia is only about 3,000 ~ 4,000 yuan. Therefore, it can be seen that the profit of tilapia farming is relatively small, and the cost and output can not be guaranteed. The actual cost and output will be different, and may be lower.
