Abstract:

Israel is located in a semiarid zone without major rivers or underground freshwater sources. In spite of the climatic constraints and water shortages, freshwater aquaculture is highly developed as an entrepreneurial activity that combines the ecological principles of the Chinese polyculture system with technologies and objectives of industrial fish production systems. Within this context, tilapia co‐culture with one or more fish species is practiced in fishponds and water reservoirs in the northern part of the country. Fish farming on a commercial scale started in 1939 with common carp (Cyprinus carpio) monoculture. The end of the 1950s started the transition to polyculture, with the addition of grey mullet (Mugil cephalus) and endemic tilapia (Oreochromis aureus and Tilapia zillii) into the carp ponds. Around 1970, when it was found that hybridization between Oreochromis niloticus females and O. aureus males resulted in tilapia with over 90% males, the uncontrolled spawning problem with tilapia was largely solved leading to increased size of the fish at marketing. Since then that hybrid has been the main tilapia cultured in Israel. Its growout is practiced in monoculture in earthen ponds and in co‐culture with common carp and/or mullet in earthen ponds and reservoirs. Sometimes, the exotic predatory red drum (Sciaenops ocellatus) is stocked to restrain uncontrolled tilapia spawning. During over 70 years of aquaculture in Israel, fish production steadily increased while the available land for fish ponds decreased, reflecting an increase in the yield per unit area. Nowadays, tilapia constitute 40–45% and common carp around 30% of the almost 18,000 metric tons (mt) of the pond fish annually marketed in the country. Israeli farmers are highly innovative and eager to try new methods and technologies, characteristics that allowed starting fish culture in a water‐limited country and foster its development. Strong cooperation between researchers and fish growers allow the efficient dissemination and quick application in the farms of the generated knowledge, as herein presented for tilapia co‐culture.
