  • Introduction to Oreochromis niloticus fingerling production systems 

     
    Fish culture is an important component of many rural development projects in areas suffering from protein shortages. Oreochromis niloticus is often chosen for its good cultural characteristics. However, an adequate supply ...
  • Introduction to intensive cage culture of warmwater fish 

     
    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 ...
  • Transporting fish 

     
    Transporting fish is a very important part of fish culture. Fry and fingerlings must be transported from hatchery to pond for stocking. Brood fish are sometimes transported into the hatchery to spawn. It may even be necessary ...
  • Organic fertilizers for fish ponds 

     
    Organic fertilizers are usually animal manures or plant wastes and cuttings ("green manure"). Manure from chickens, goats, sheep, ducks, pigs, rabbits, cattle and horses are excellent fertilizers for fish ponds. Other ...
  • Chemical fertilizers for fish ponds 

     
    Chemical fertilizers are normally used to improve soil fertility and increase agricultural crop yields. In fish ponds they stimulate phytoplankton production which increases fish yields. They contain inert filler material ...
  • Feeding your fish 

     
    Fish grow fast and stay healthy if they have enough nutritious food to eat. Living organisms are natural fish foods and are produced in the water where the fish live. Phytoplankton (microscopic plants), zooplankton ...
  • Introduction to fish culture in rice paddies 

     
    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 ...
  • Introduction to water harvesting 

     
    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 ...
  • Single pond system for sustainable production of Oreochromis niloticus 

     
    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 ...
  • Net enclosure system for Oreochromis niloticus fingerling production 

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

     
    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. ...
  • Oreochromis niloticus fry and fingerling production in tanks 

     
    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 ...
  • Reproductive biology of Oreochromis niloticus 

     
    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 

     
    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 polyculture of fish 

     
    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 ...
  • Culture of hand-selected male tilapia 

     
    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 tilapia culture 

     
    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 ...
  • Introduction to fish pond fertilization 

     
    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 fish culture in ponds 

     
    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 ...
  • Introduction to aquaculture 

     
    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 ...
