Description |
Highly saline ponds fed by underground water, commonly found under deserts, could produce 100,000 kg of fish per hectare. New techniques developed at Tel Aviv University in Israel are showing that desert communities could use such ponds as new sources of food. The technique involves the breeding of tilapia in these ponds where most of their food could be met through the natural production of algae in the ponds alone. The brackish water can be kept clean with special floating aerators. As a result of these techniques, the rural desert settlement of Ein Yahav is currently able to produce more than 20 tonnes of fish per year from each hectare of pond. The ponds yield up to 30 fish per square metre compared to the two-three fish per square metre in conventional ponds. In related experiments, the scientists bred ducks simultaneously on the ponds, feeding them a combination of algae and grains. The duck wastage serves as further fertilizer for the ponds and yields could be as much as 400 kg of duck meat per hectare.
