There are 2 places where catfish are produced. They are grown in the wild and also in fish hatcheries. When catfish are grown in fish hatcheries, they live in ponds that are only 5 feet deep! Its amazing how little water they require.
In the wild, catfish usually feed on both dead and living bait fish. They are also known to feed on worms and bugs which make their way into the water. In a hatchery, catfish are forced to eat food pellets, similar to dogs or cats. I am guessing it is much more profitable for the hatcheries to feed the catfish pellets instead of mass quantities of insects...although I would love to feed them every mosquito in the world!
Female catfish can produce a massive amount of eggs every year. Studies show that each female catfish produces 4000 eggs for every pound of their own body weight each year. That is an incredible figure.
When a catfish first breaks out of the egg, they are known as a "sac fry". The reason they are called this strange name is because they are still dependent to the yoke sack that they are attached to. Once they mature, the yoke sack falls off and they their feeding habit is similar to larger, fully developed catfish.
After the yoke sack falls off of the catfish, and they reach a length of 4 inches long, they are known as "finger lings". Some people use their finger as a unit of measurement also.
As you have read above, catfish are an amazing creature. They are my favorite fish to catch and they are also my favorite fish to eat!
