Is it feasible to raise pigs on barren hills and then use pig manure to raise fish?
Everyone help me take a look: raising pigs on barren hills, using pig manure to raise fish, is it feasible?
I have newly taken over a piece of mountain land, right next to a small reservoir, (mountain land 150 mu, water area about 30 mu). Preliminary ideas and questions: build a pig farm against the mountain, discharge waste directly into the reservoir, and use pig manure to raise fish, which can solve the waste discharge problem.
1. Is the arrangement reasonable?
2. What scale is suitable for the pig farm. (No separate waste discharge system designed)
3. How much investment is needed for pig farm construction?
I am a layman. Do any experienced seniors have good suggestions?
--------------------------------------
The pollution consumption of 1 mu of land by one sow
For mountain land, calculate the actual usable area according to the terrain. For a farrow-to-finish pig farm, one sow generally needs at least 20 sq m.
For farrow-to-finish, 1 sow costs 10,000 yuan, not counting pig house construction.
It is recommended that manure water undergo three-stage sedimentation before raising fish. Otherwise they will all die.
--------------------------------------
Raising pigs on barren hills and using pig manure to raise fish is completely feasible.

Thank you to the person above, I have learned something.

If it is discharged directly into the reservoir, won't that turn it into a big manure pit? This reservoir stores water to solve emergencies. In this way, the potential hidden dangers are very great. If you want to save on the waste discharge system, it is best not to build it at all, so as not to bring shame to the green mountains. If you want to build a pig farm, you should first tell yourself that you can leave a patch of blue sky for the next generation.

Pig manure and manure urine water go into a biogas digester, and using biogas residue and biogas slurry to feed fish should be feasible!

This reservoir is now no longer used as a domestic water source. The contract clearly states it is only responsible for a small part of farmland water use.

Pig manure first goes into a biogas digester for fermentation, and then is put into the fish pond. It should be feasible!
--------------------------------------
Although pig farming today is not for the benefit of one place, it should also become a place that draws everyone's attention. Farmland irrigation water, can it be underestimated?
Water is a necessary raw material for the biological yield of crops. If the water is rich in elements such as nitrogen and phosphorus, then it is sewage;
If the manure contains a large amount of undegraded substances, such as those produced by feeding high-copper feed, high-zinc feed, and high-iron feed, then direct discharge may lead to reduced crop yields. Have you considered this?
If the green mountains and clear waters are "managed" with such short-sightedness, I am afraid that before long we will all need to live wearing gas masks.Reply to 7#Huang Laowu
