6. Fish
Maybe sounds unusual, but fish is also considered to belong to livestock. We put fish farming at the last place on our list of most profitable livestocks for small farms, not because it is least profitable (being very profitable on the contrary), but because of the specific conditions, it requires. That includes the type of land area you have available. The best place would be near or next to the natural water course. Fish farming, of course, requires building a cage, pond or another enclosure that has a constant flow of fresh water. Establishing this basic point, fish farming pays off because you get a huge amount of fish that you can place on the market. Market demands should dictate your fish species choice, some of them being carp, salmon, trout, tilapia cod, etc.
