In the arid Negev desert, a landlocked industrial facility is growing a prized marine fish. Aquatech Fisheries Ltd. has spent nearly a decade proving that a large-scale, land-based recirculating aquaculture system (RAS) can work commercially in Israel, raising Barramundi for the domestic market [FishChoice]. The company’s claim is specific: it operates the largest and only successful industrial RAS fishery in the country [Israeli Aquaculture Innovators]. For founder Yoav Dagan, who brings three decades of aquaculture experience, the project is a validation of a sustainable food production model [Aquatech Fisheries].
The desert wedge
Aquatech’s competitive wedge is its location and its operational proof. The core technology, a recirculating aquaculture system, filters and reuses over 95% of its water [Israeli Aquaculture Innovators]. This allows for a tightly controlled environment, minimizing disease risk and enabling year-round production of Barramundi. The company’s stated annual production capacity is 2,000 tons, all distributed fresh across Israel [Aquatech Fisheries].
A founder with deep roots
The venture is closely tied to the expertise of Yoav Dagan. Dagan is also a Partner and VP of Business Development at AquaMaof Aquaculture Technologies, a separate firm that designs and builds large-scale RAS facilities globally [Blue Food Innovation Summit, 2025]. Roy Golan, responsible for the fishery’s day-to-day operations, rounds out the leadership [Aquatech Fisheries]. The company’s growth appears to be revenue-financed, with a single named investor, Microdel, and no publicly disclosed venture rounds.
| Role | Name | Key Background |
|---|---|---|
| Founder / Driving Force | Yoav Dagan | 30 years in aquaculture; Partner/VP Biz Dev at AquaMaof [Aquatech Fisheries, AquaMaof]. |
| Operations Lead | Roy Golan | Operational management in aquaculture and agriculture sectors [Aquatech Fisheries]. |
The expansion thesis and its hurdles
Aquatech’s ambition extends beyond its desert walls. The company is planning an expansion strategy to identify new partnerships and projects to spread its RAS technology worldwide [Aquatech Fisheries].
- Capital intensity. Building a new RAS facility requires significant upfront investment. Aquatech’s revenue-financed model may constrain the pace of its own physical expansion compared to venture-backed peers.
- Species specialization. While Barramundi is successful in Israel, the global race in land-based aquaculture is currently dominated by Atlantic salmon.
- Technology transfer. The jump from operating a single successful facility to profitably licensing its knowledge system is unproven.
For the population in Israel, the standard of care has traditionally been imported frozen seafood or limited local catch. Aquatech’s model offers a consistent supply of fresh, locally farmed fish, reducing food miles and providing supply chain security.
