Carp or what the gov imported from Europe long ago known as "white" carp, has to be one of the most easiest meat food sources on the planet.
1 small PA farmer 150 years ago fed NYC with fresh carp (FISH)
They say a big carp can lay 1 million eggs. IN NATURE than means only a few will survive, because most predator fish all eat CARP.
Carp are grass eaters, bugs, small worms and most anything small.
They are easily raised on grains, because they eat vegetables, seeds, grass.
CARP can be raised on cow and pig poop, for the simple fact cows can not easily digest corn and their corn comes back out and carp can eat it and carp eat all grasses, so everything a cow/horse eats, the carp can eat it again.
Carp can be caged raised, wild raised and today, once again, after 200 years, the carp is becoming known as a good tasting fish--something asians and Spanish have known for centuries.
The point is simple----so many easy food sources beyond chickens, cows and pigs and in the world of fish------they expect 99% of their babies to be eaten.
YET, believe it or not---fish can grow to like humans, they will even follow humans around as long as they can see them....
A FISH can identify your voice, your shape and learn to trust you and they never trust strangers----strange humans have to earn their trust.
For those that eat meats, the fish isa far better choice that the 2 legged buzzards.
