Catfish Farming - Overview of Methods

There are three main systems for farming channel catfish: levee, watershed, and cages.

Levee Ponds
Levee ponds are built on a flat area with earthen levees on all four sides, between 4 to 6 feet high. Water is often supplied from a well. If sufficient aeration equipment is used, as many as 4,500 fish per acre can be supported.

Watershed Ponds
Watershed ponds are built on slopes, often in a series of stepped ponds. They are formed by build
ing dams to catch runoff water. Like levee ponds, they are generally 4 to 6 feet deep, since making them shallower allows weeds to grow, and making them deeper can cause low oxygen problems.

Cages can be used to let a catfish farmer grow fish in a lake or pond where harvesting and monitoring fish would normally be extremely difficult. Care must be taken to ensure that the cages do not become clogged with algae, and that there are no more than 1,000 fish per acre of surface area.
