EILAT, Israel | Israel has officially launched a National Tuna Project to build the scientific and commercial capacity to breed Atlantic bluefin tuna under controlled conditions and eventually establish a sustainable domestic aquaculture industry.
The project builds on nearly two decades of research at Israelโs National Center for Mariculture in Eilat and brings together government agencies, researchers, environmental organizations and private industry.
The Ministry of Agriculture and Food Security is investing approximately NIS 30 million in the initiative, with additional investment from agricultural cooperative Granot Group.
The long-term objective is ambitious: establish a breeding population of Atlantic bluefin tuna in Israel that can reproduce in captivity, providing eggs and juvenile fish without depending on the capture of wild tuna.
If successful, the program could strengthen Israelโs food security, reduce pressure on wild tuna populations, and potentially create a commercially valuable new Israeli aquaculture industry.
A significant milestone was reached in June when fertilized bluefin tuna eggs were transported from Malta to Eilat. Dozens of juvenile tuna produced from those eggs are now being raised at the National Center for Mariculture.
Building an Israeli Tuna Breeding Population
Atlantic bluefin tuna are among the worldโs most commercially valuable fish, prized particularly in the international sushi and sashimi markets.
They are also exceptionally challenging to breed in captivity.
Bluefin tuna are large, fast-swimming migratory predators with complex reproductive and environmental requirements. Developing a reliable closed breeding cycle requires scientists to control factors including water quality, nutrition, temperature, reproduction, and the survival of highly sensitive larvae and juvenile fish.
The Israeli project aims to overcome those challenges by building the scientific infrastructure and expertise needed to maintain a breeding population in captivity.
The ultimate goal is what aquaculture researchers call a closed-cycle system. Instead of repeatedly collecting eggs, larvae, or young fish from wild populations, breeding adults maintained in captivity produce the next generation.
That next generation can then mature and reproduce, allowing the process to continue without relying on wild stocks.
Achieving that cycle with Atlantic bluefin tuna would represent a significant scientific and commercial accomplishment.
Nearly Two Decades of Research in Eilat
The National Tuna Project did not begin from scratch.
Researchers at the National Center for Mariculture in Eilat have been studying tuna reproduction and aquaculture for nearly two decades, building expertise that is now being expanded into a national initiative.
The center operates under Israel Oceanographic and Limnological Research and conducts research into marine aquaculture, fish biology, nutrition, reproduction and other technologies intended to support sustainable use of marine resources.
The new project involves the Prime Ministerโs Office, Ministry of Agriculture and Food Security, Israel Oceanographic and Limnological Research, KKL-JNF, Granot Group and the Seanovation innovation center.
The combination of government support, scientific research and private investment is intended to move the technology beyond laboratory research and toward commercial-scale production.
The arrival of fertilized tuna eggs from Malta in June marked an important practical stage.
Researchers were able to transport the eggs to Eilat, hatch them and begin raising the resulting juvenile fish under controlled conditions.
Dozens of those young tuna are now being maintained at the research center as scientists study their growth and development.
Keeping the fish alive and healthy as they mature will be one of the important steps toward establishing a permanent Israeli breeding population.
Food Security Meets Israeli Biotechnology
The project is also part of a broader effort to apply Israeli agricultural and biotechnology expertise to food production.
Israel has long invested in technologies designed to produce food under conditions of limited land, water, and other natural resources. Aquaculture offers another potential avenue for increasing domestic food production without relying exclusively on conventional agriculture or wild fisheries.
For Israel, breeding a high-value marine species domestically could offer both strategic and economic benefits.
A successful closed-cycle system could provide a more predictable source of tuna while reducing exposure to international supply disruptions and wild-catch fluctuations.
It could also create intellectual property, specialized equipment, and breeding expertise with potential applications beyond Israel.
Commercial production, however, remains a longer-term objective. Raising dozens of juvenile tuna at a research facility is substantially different from operating an economically viable aquaculture industry at scale.
Researchers must still demonstrate that the fish can be raised successfully to reproductive maturity, produce viable eggs, and establish subsequent generations under controlled conditions.
Potential Export Industry
The international market gives the project considerable commercial potential if it can overcome those scientific hurdles.
Atlantic bluefin tuna commands high prices in global seafood markets, particularly in Japan and other countries with strong demand for premium sushi-grade fish.
At the same time, the species has historically faced significant pressure from commercial fishing, making sustainable production an important objective for researchers and fisheries managers.
Closed-cycle aquaculture could provide an alternative source without repeatedly removing young tuna from the wild.
For Israel, success could ultimately mean more than producing fish for the domestic market.
Technology developed through the program could potentially support a specialized export industry built around aquaculture systems, breeding expertise, genetics, nutrition and other marine biotechnology.
The project therefore sits at the intersection of several Israeli priorities: food security, agricultural technology, marine science, environmental sustainability and economic innovation.
The juvenile tuna now swimming in Eilat represent an early stage in that effort.
The more consequential milestone will come if researchers can raise those fish to maturity and establish a self-sustaining breeding population, turning nearly two decades of Israeli research into a new domestic aquaculture industry.
