Sturgeon Aquaculture—Specialized Techniques: Determining the Stage of Sexual Maturity in Female Sturgeon for Artificial Spawning: The Egg Polarization Index or PI

Frank A. Chapman and Joel P. Van Eenennaam

FA-153 describes a simple field and laboratory test used to assist in predicting ovulatory response in female sturgeon, which uses the egg size and position of the nucleus in the cytoplasm as indicators — the principle behind it, materials needed, biopsy procedure, and how to determine the egg polarization index.

Teach Aquaculture Curriculum: Dancing with Brine Shrimp

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

Brine shrimp live in and are harvested primarily from natural salt lakes and solar salt operations around the world. Two natural sources of brine shrimp in the United States are the Great Salt Lake in Utah and San Francisco Bay in California. Adult brine shrimp are also called "sea monkeys" and are used for entertainment or to feed aquarium fish. Brine shrimp can be used to observe, control, and manipulate a life cycle under laboratory conditions during a period of less than 2 weeks. They can be

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.

Teach Aquaculture Curriculum: Spawning and Rearing Bivalve Molluscs—Larval Culture

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

In this activity students will use an ocular micrometer to measure the length of bivalve larvae, monitor the density of larvae in their culture system, and understand production protocols used in bivalve hatcheries. This activity will take about 15 minutes per day for approximately two weeks; this is the amount of time it will take for larvae to develop from egg to metamorphosis (setting).

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.

Preparing Your Own Fish Feeds

Juli-Anne B. Royes and Frank Chapman

This paper presents examples of: 1) Experimental and practical fish feed blends or formulas which are nutrient balanced and adaptable to particular conditions; 2) The formulation and preparation of a semi-purified ornamental African cichlid fish diet that can be used in the laboratory or when small quantities of feed are needed; 3) The preparation of a gelatin-based diet that is often used to administer medicines or other chemicals. Background information on nutrition, feedstuffs and feed formulations are presented with emphasis primarily on the feeding of ornamental “aquarium” fishes.

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.
