Tilapia Farming in Egypt

A 2014 report on aquaculture in Egypt presents some interesting information:

  • Despite the pressure on water, Egypt has the largest aquaculture industry in Africa with a market value of over $1.3 billion.
  • The industry now provides 65% of the country’s fish needs, with virtually all the output coming from small and medium-scale privately owned farms.
  • The main farmed fish is Nile tilapia and Egypt is the world’s second largest producer of farmed tilapia after China. Grey mullet and carp are also farmed, sometimes in mixed ponds with tilapia.
  • From small levels of production in the early 1990s fish farming has expanded rapidly while capture fishing has remained fairly constant, even declining somewhat after peaking at the beginning of the 21st century.
  • Aquaculture is also important in providing employment to an estimated 100,000 people of whom 50% are youth.
  • With the exception of Fayoum, aquaculture takes place in the Nile Delta region and mainly around the Northern Lakes area.

2.5. Status of fish production in Egypt

Capture fisheries in Egypt are in decline due to; overfishing, pollution, illegal, unreported and Unregulated fishing (IUU), relaxation in the implementation of laws and regulations, lack of interest in clearing Straits and waterways, poor sustainable management of fisheries and aquaculture, illegal fishing operations of fry. In addition to the building of Aswan High Dam (that reduced the annual flood cycle of the Nile), the application of partial pond flushing, aeration and sex reversal are the major steps that contributed to the expansion,
intensification and growth of total tilapia production in ponds in Egypt.

The General Authority for Fish Resources Development (GAFRD) planned two-sided strategy aims to increase the productivity of freshwater aquaculture operations, while encouraging investment in marine aquaculture.

Finding more fish, between Egypt and Vietnam

A cooperation agreement between Egypt’s General Authority for Fish Resources Development (GAFRD) and Vietnam’s Ministry of Agriculture and Rural Development (MARD) inked in May sets a framework for joint fisheries development. The protocol encourages researchers, trainers and quality control technicians in the two countries to share data, and calls for exchange visits of fisheries and aquaculture officials

Tank Culture of Tilapia

Tilapia can be raised in ponds, cages, and tanks. The pond and cage techniques are useful when water supplies are readily available. Tank culture offers a good alternative for raising tilapia in areas where land and water sources are limited. Tilapia can often be grown intensively in tanks because you can control environmental parameters, feeding, and water quality. Tank culture can be capital intensive, so you will need to do a careful careful evaluation of the economics to see if this technique makes sense in your location.

Here is a quick summary of the major advantages and disadvantages of tank culture.

Advantages
Water quality can be controlled
Reduced water needs, especially if using a recirculating system
Intensive culture supports high production on small land parcels
High degree of control over environmental parameters (e.g., DO, pH, water temp., waste)
Stocking in high density disrupts normal breeding patterns and supports high growth rates
Fish feeding and harvesting are less labor intensive
Disease treatment is easier
Disadvantages
No or limited natural food available, so fish must be feed a complete diet
Higher costs to maintain water pumps and aeration
Filtration in recirculating systems is expensive and requires maintenance
Backup systems are required to sustain fish if power is disrupted
Higher culture densities can increase fish stress and disease
Any water discharge must be controlled

Opposing Flows Technology has developed a tank system for intensive cultivation of aquaculture species, including tilapia. To review the economics of their modular system see http://aquaculturetanks.net/tilapia/
