The following is a simplified description of the inland aquaculture used for growing fishes with some details on components and units of the system (translated from
Arabic and summarized from [4]).
1.3.1 Fish Hatchery
Cement basins are built of red brick and are cemented with waterproof cement.
During this stage the basins are inoculated with fish hatchery with an average weight
of 1 gm until it reaches 40 gm in average.
1.3.2 The Rearing Basins
Cement basins are built by red bricks with water proof cement. During this stage,
the basins are inoculated with fish fingerlings of the average weight of 45 gm until
it reaches 400–450 gm.
1.3.3 Units Associated with the System
1. Water storage reservoir
This is a floor basin that can take 100 m
3 of water volume to guarantee sustainable
water supply in the culture. The basin will be lined with an insulating plastic to detain
water within the basin.
2. Sedimentation basin
This basin is built to allow sedimentation where it has a small tilt with its two thirds
in the direction of waste opening, and the last third is separated with a short blocking
wall for water to rise above it to move to that third. This specific third is the one
that contains clean water. The culture water is dispensed after forcing it through
biological filter.
3. Biological filter
4. It is opaque and well-aerated tank that functions in purifying water. The water
tank is of 50 m
3 and empty area of 50 m
3
5. A headquarters
One floor designed and furnished to meet the needs of the project team.
6. Fodder store room
This is used for preserving fodder enough for at least one month. Storage conditions
are met, and the humidity must be kept to the minimum and ventilation openings are
provided.
