• Sudan is blessed with abundant, suitable resources (land. water and weather) which favors for aquaculture development. There is 6500 km of River water covering an estimated 2 million ha.
• The River Nile and it’s tributaries as a major source of water for agriculture, has also been an important source of fish.
Sudd region of White Nile, which extends for about 500 km, is a swampy area about 17,000 km2. Besides the River network there are isolate eastern rain reservoirs
• and ponds distributed in the western and regions of Sudan and a vast network of irrigation canals in the Gezera Agricultural Scheme (2.2million feddan of fertile land and over 4000km of large water
• canals with some18 billion m3 of water available)
• so some 100,00 Mt of fish could be produced in Gesera ponds and cages in the short – run, with increase revenues to framers and economics development in rural communities .Benefits include multiple water use for fish and crops.
• Inland fishery is mainly concerned with the major reservoirs of SUDAN.
• The total estimated sustainable fish yield of the freshwater is over 110,000 metric tons/year.
• The actual present production level is about 30-40%.
Required fish for Sudan population: 534,141 MT/year.(according to the fish consuption ratio which are appro 1.3 kg/personal/year
• of the Sudan can be considered The inland fishery as three main sectors as follows:
• 1-Subsistence sector:
• Found all over inland waters, mainly in the south in swamps area, such fishing is undertaken with spear, simple nets, cats net or lines from shores. Production level more than 10000 tons/year.
• 2-Artisanl Sector:
• Mainly in White Niles and Blue Niles. Usually a fisherman owns one traditional oar-propelled boat and is sharing the catch with 4 to 5 crewmen
• 3-Commercial Sector:
• This less developed. In the south traders used to set up seasonal camps for producing sun-dried salted fish, which was sold locally in areas remote from Nile or to some neighboring countries e.g. Zaire. In some areas like Roseries and Nubia Lake small commercial sector enterprises and companies recently evolved as commercial sector.
• About 90% of fish production in Sudan is marketed fresh. Other significant methods of handling and processing involve sun-dried-salted –wet-salted fish and smoked.

• Fishing practice is believed to have started in Sudan during the Eighteenth century a long the whole Nile system.
1. The industry characterized by traditional means of production employing a variety of primitive gears ranging from hooks, lines, spears and fish traps. Recently with increase the demand of fish. This lead to use of Nylon seine And gill nets, trammels and trolling methods as well as motorized steel and fiber boats.
Indigenous Species:
• The indigenous fish stock is formed of some 129 spp. belonging to more than 13 families.
• The fish species e.g. are Lates niloticus, Bagrus bayad, B. domac, Tilapia spp., Labeo spp., Alestes spp., Hydrocynus spp., Clarias spp., Synodontis spp., and ect…

• The outstanding features of The Red Sea are:
• Very high salinity.
• Absence of river.
• Absence of major oceanic currents.
• Presence of coral, fringing, barrier reef and atolls.
• Very narrow continental shelf.
• The above factors have adversely affected fish production.
• The SUDAN coastline of about 720km consists almost entirely of coral reefs with a line of offshore reefs (from 5 to 25 miles off the shoreline).
• The marine fish catch from the Red Sea is less than 1000 tons per year (FAO). The landing points are Port Sudan, Suakin, and Mohammed Goal.
Two types are used for fishing. The slender canoes (Huirs, 10-20 ft long) used in shallow waters in side the reefs and harbors. As well as small boats (15-25 ft long) powered by oars and sails–only a minority of which are motorized, used for fishing with troll lines, hand lines, gillnets and beach seines
There about 65 species of economically important marine bony fishes in Sudan , in addition to sharks, rays, shrimps, lobsters, crabs, molluscs and sea cucumber. In artisanal fisheries, the nine following taxa account for 60 - 70% of the catches: gushar (Epinephelus spp.), bohar (Lutjanus bohar), asmoot (Lutjanus gibbus) shaoor (Lethrinus spp.), bayad (Carangidae), najil (Plectropomus maculatus), farisi (Aprion sp.), abu garin (Naso unicornis), arabi (Valamugil seheli) and sharks (mainly Carcharhinidae and Sphyrnidae).
The shellfishery potential may be characterized as unique and holds considerable promise. The black-lip mother-of-pearl shell Pinctata margaritifera and Trochus dentatus is the present the only mollusk’s of commercial importance in Sudan
Fish culture in Sudan started in 1953, at El shagra, as experimental demonstration farm, for providing basic research stand- point data, subsequently used for monitoring
Applied research with the objective of expansion of aquacultures practice. After that fish Culture extended among interested people, institutions in the Agovernment, semi governmental and private sector a(more than 50 farms such as Waha and El sellaid Gov and Jebel awlia private farm ) for different purposes such as: -
1.Fish production for consumption
control the weeds in the irrigation canals.2
control mosquito larvae , sport..3
There are three species commonly used in fish farming in the Sudan, but the
Oreochromis niloticus was found to be most appropriate and it was a popular table fish
These are
1.Oreochromis niloticus
Sarotherdon galilees.2
Tilapia zilli.3
Sometimes the farmers they are used the following species to control the over-population of Tilapia:
Lates niloticus (Nile perch) 1.
Clarias lazera.2
Bagrus Bayad.3

There are different fish ponds and designs used in Sudan these are:
Earthen pond.1
Concrete ponds.2
There are two systems adopted:
Extensive culture. {Using Organic manure, chicken and cow.1
2.Semi- intensive cultures. {Using organic manure, inorganic (super phosphate, calcium carbonate and quick lime) +supplementary feeds (cotton seed +wheat bran)
The collection of the fingerlings in Sudan by these methods:
1/Collection from the Rivers (during the breeding season).
2/ Rearing the brood stock collected from the wild.
3/ Fisheries Research Center ponds.
4/ Khartoum State(Gov) Hatchery

The stocking density rate in Sudan is about 8.000-10.000 spp/ha
The maximum productivity of the fish ranged between
2.5-3 tons/ha/year for tow crops

There some diseases and predators occurs during the fish farming:
B- Predation
C-Viral Diseases
D- Bacterial diseases
E- Nutritional diseases
F-Deformities problems

Weakened of the basic infrastructures.1
2.Lack of inputs
High qualities of seed.3
Equipments and tools.6
Inadequate communications between the research centers and the production units.7
Lack of fish farming techniques, experience and qualified personnel.8
Lack of adequate funds.9 is considered less profitable, more risky if compared with the short-term agricultural investment and insecure business for investors
A national aquaculture policy and strategy is needed to define the role and responsibilitiesofGovernment and private sector.Aquaculture awareness and steady continues and financial support is neede .in-side and outside training programe should be adopted in order to rectified the professional.
Fish farming is considered to be one of the important factors for social and economic development, contributed in providing food, creating opportunity job, poverty reduction,, increasing export and reducing
In Sudan it is hoped that aquaculture practices done successfully, and our training can contributes meaningfully in this practices. So aquaculture may become more profitable busin
