More than one-fourth of all animal protein consumed by man is aquatic in origin. Regional differences range from Asia where more than one-fourth of dietary animal protein is fish to North and South America where less than ...

Introduction to polyculture of fish 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Polyculture is the practice of culturing more than one species of aquatic organims in the same pond. The motivating principle is that fish production in ponds may be maximized by raising a combination of species having ...

Introduction to tilapia culture 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Tilapia are native to Africa, but have been introduced in many countries around the world. They are disease-resistant, reproduce easily, eat a wide variety of foods and tolerate poor water quality with low dissolved oxygen ...

Reproductive biology of Oreochromis niloticus 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Oreochromis niloticus are native to most major Northern and Central African river systems and have been distributed widely throughout the tropical world. The number of dorsal fin rays and dorsal spines and the presence of ...

Eliminating unwanted fish and harmful insects from fish ponds 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Poisons or "toxicants" are used to eliminate unwanted fish, insects and other harmful organisms from a pond. A wide variety of poisons is available. This manual describes some which are commonly used.

Introduction to fish pond fertilization 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
A fish pond is a unique environment created by man. It must be managed properly to achieve good fish production. For centuries fish farmers have increased fish yields in ponds by using inorganic or chemical fertilizers and ...

Introduction to intensive cage culture of warmwater fish 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Cage culture of fish is a method of raising fish in containers enclosed on all sides and bottom by materials that hold the fish inside while permitting water exchange and waste removal into the surrounding water. Cages are ...

Introduction to fish culture in rice paddies 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Rice-fish culture is not widely practiced around the world. Most information comes from Asian countries, particularly the Philippines, Indonesia, and Japan, where traditional rice farming methods have been refined over ...

Production of 1-gram, mixed-sec Oreochromis niloticus fingerlings in earthen ponds 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Grow-out ponds stocked with mixed-sex tilapia fingerlings of different ages will yield large numbers of small tilapia at harvest because some of the stocked fish become sexually mature and reproduce soon after stocking. ...

Introduction to water harvesting 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Throughout history, man has been dependent on an adequate water supply for his food, security and well being. Water is a universal need and is considered the principal limiting factor for human life. Destruction of natural ...

Oreochromis niloticus fry and fingerling production in tanks 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Tilapia fry may be produced in square, rectangular or circular tanks made of wood, concrete, bricks, fiberglass, or plastic with indvidual water inlets and drains. Tanks may be expensive, but are common where space is ...

Net enclosure system for Oreochromis niloticus fingerling production 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Net enclosures can be used in every phase of tilapia culture from fingerling production to growing market size food fish. In Southeast Asia the "hapa" net system for Oreochromis niloticus fingerling production is very ...

Culture of hand-selected male tilapia 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
A major problem of pond-cultured tilapia is excessive reproduction, and subsequent stunting of fish due to overcrowding. To combat this problem a pond may be stocked with all-male fish. This technique is monosex culture ...

Introduction to fish culture in ponds 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
A pond is a body of standing, as opposed to free-flowing, water that is small enough to be managed for fish culture. Fish production in farm ponds can provide protein and profit for farmers. Fish such as oreochromis and ...

Single pond system for sustainable production of Oreochromis niloticus 

Auburn University International Center for Aquaculture and Aquatic Environments (2019-12-05)
Farmers can grow mixed-sex tilapia for food and still produce their own fingerlings in a single pond. The system requires few inputs and works well on subsistence farms. Farmers using this system may no longer need to ...

Feeding your fish
