Culture of Hybrid Tilapia: A Reference Profile

Frank A. Chapman

This document is about Tilapia, which is a generic term used to designate a group of commercially important food fish belonging to the family Cichlidae; the expression is derived from the African native Bechuana word "thiape," meaning fish. Cichlids are classified in the large order Perciformes, and inhabit the fresh and brackish waters of Africa, the Middle East, coastal India, Central and South America. True tilapias, however, are native only to Africa and the Middle East. Although exotic to the United States, populations of tilapia are now established in Arizona, California, Hawaii, Florida, Nevada, North Carolina, and Texas. First published July, 1992.

Teach Aquaculture Curriculum: Fish-Eating Contest

Amber L. Garr, Cortney L. Ohs, Brian E. Myers, Craig S. Kasper, R. Leroy Creswell, Frank A. Chapman, Carlos V. Martinez, and Elisa J. Livengood

There are numerous fish species cultured in the world. Fish are cultured in ponds, tanks, and cages. Some are fed floating, pelleted food and some consume live algae. The types of diets used in aquaculture have been developed specifically for the feeding strategies of the cultured animal. In this lesson, students will mimic fish with different mouth positions by adopting different feeding behaviors and by trying to capture marshmallows without the use of their hands.

Farm-Raised Channel Catfish

Frank A. Chapman

This document is about Channel catfish (Ictalurus punctatus). Channel catfish belong to the family Ictaluridae, in the large catfish order Siluriformes. The order includes over two thousand species, and most of them inhabit the fresh waters of the tropics. In the United States, the family Ictaluridae is native to the water drainages east of the Rocky Mountains, and contains about forty-three recognized species. Other important commercial species in the family include the blue catfish (I. furcatus), white catfish I. catus), yellow bullhead (I. natalis), brown bullhead (I. nebulosus), black bullhead (I.melas), and the flathead catfish (Pylodictis olivaris). First published in July, 1992.

Teach Aquaculture Curriculum: How big is that pond?

Cortney L. Ohs, Amber L. Garr, R. Leroy Creswell, Elisa J. Livengood, Brian E. Myers, Carlos V. Martinez, Frank A. Chapman, and Craig S. Kasper

This activity will provide examples of volume and area calculations of ponds of various types and shapes. The students will learn to calculate volumes and surface areas of ponds and use this information to calculate stocking densities and chemical application rates. Students will be able to make these calculations in both US and metric units. This activity has direct application to aquaculture, and these calculations are commonly used by federal and state agencies, private companies, engineers, toxicologists, and other people related to the aquatic sciences.
