Abstract

An aquaponics system using the brackish waters of the Negev (conductivity approximately 4500 μS/cm) is described. Tilapia sp. were grown with a variety of vegetables, herbs and other plants within three systems within an aquaculture hothouse: a brackish water floating raft system, a brackish water gravel system and a fresh water floating raft system. Water quality remained adequate within all systems for plant growth and fish health. Growth rates for fish were low, averaging about 1.4g/day. Standing stock of fish at harvest was 12.5 kg/m3. Plants required the addition of iron chelate to contend with chlorosis and some macro and micro nutrients seem to have been in short supply.
