Can pig manure feed fish?

1. Pig manure is the product of raw feed digested by pigs and excreted. Studies show that pigs can only digest and absorb 20%~30% of nutrients in food, and the rest are excreted with feces, so pig manure is still a nutritious feed.

2. The digestibility of fish is very weak, and the feces digested and absorbed by pigs go through a similar fermentation and digestion process, which is more conducive to fish absorption.

3. Some fish are corrosive, such as silver carp, and they like to eat feces.

However, feeding fish with pig manure often brings inevitable risks, such as easy deterioration of water quality, possible presence of pathogenic bacteria in pig manure and so on. Therefore, it is suggested that pig manure should be composted and fermented when it enters Tangqian to reduce the above risks.
