Artificial Reef in Red Sea Teems with Life
Artificial Reef in Red Sea Teems with Life

EILAT, Israel, August 19, 2013 – In 2007, an artificial reef designed by Ben-Gurion University of the Negev (BGU) researchers was placed in the Gulf of Eilat to reduce environmental pressure on the region’s natural reef.
Now teeming with life, a new study using the “Tamar Reef” shows that divers assign economic importance to aspects of reef biodiversity. These findings could help underwater conservation efforts.
According to the study published in the ICES Journal of Marine Science, divers were willing to pay to improve the reef’s attributes and were able to differentiate and rank their preferences of biodiversity, numbers of fish and corals, coral species richness, fish species richness, coral size, coral abundance, and fish abundance.
“This result was exciting to us, since it shows that the general public as well as scientists place a high value on biodiversity and that visitors understand the fundamentals that constitute a coral reef community,” says Dr. Nadav Shashar of BGU’s Marine Biology and Biotechnology Program in Eilat, Israel.
“This may help direct conservation efforts undertaken in designing future marine reserves and pre-planned artificial reefs.”
Dr. Shashar and his team surveyed 295 divers to evaluate their willingness to pay for improving various elements of a coral reef. They were shown a series of photographs of the BGU-created Tamar Reef with varied densities and compositions of fish and coral species.
The researchers focused on the overall aesthetic value of each component, but also how divers’ aesthetic preferences compare with scientific biodiversity attributes that might be of interest for conservation purposes.
The artificial reef project is a collaboration between Israelis and Jordanians to restore the local Gulf reef culture. The Tamar Reef was the first of four reefs installed in the Red Sea. Students and faculty from both countries work together in studying the artificial reef and how it affects the marine ecology in the area.
Special coral nurseries were developed to augment coral diversity. Small fragments developed into large corals and were planted on the artificial reefs.
“One of the nurseries developed into an entirely new ecosystem of a floating coral reef with all types of fish; we even filmed a turtle stopping by to feed,” Shashar explains.
“We are not just studying biodiversity but helping to reestablish fish and marine life that has been depleted in the Gulf.”
The study was partly supported by the US-AID MERC program under grant number TA-MOU-05-M25-069 and by the Halperin and the Schechter foundations.
ABOUT AMERICANS FOR BEN-GURION UNIVERSITY
By supporting a world-class academic institution that not only nurtures the Negev, but also shares its expertise locally and globally, Americans for Ben-Gurion University engages a community of Americans who are committed to improving the world. David Ben-Gurion envisioned that Israel’s future would be forged in the Negev. The cutting-edge research carried out at Ben-Gurion University drives that vision by sustaining a desert Silicon Valley, with the “Stanford of the Negev” at its center. The Americans for Ben-Gurion University movement supports a 21st century unifying vision for Israel by rallying around BGU’s remarkable work and role as an apolitical beacon of light in the Negev desert.
About Ben-Gurion University of the Negev
Ben-Gurion University of the Negev embraces the endless potential we have as individuals and as a commonality to adapt and to thrive in changing environments. Inspired by our location in the desert, we aim to discover, to create, and to develop solutions to dynamic challenges, to pose questions that have yet to be asked, and to push beyond the boundaries of the commonly accepted and possible.
We are proud to be a central force for inclusion, diversity and innovation in Israel, and we strive to extend the Negev’s potential and our entrepreneurial spirit throughout the world. For example, the multi-disciplinary School for Sustainability and Climate Change at BGU leverages over 50 years of expertise on living and thriving in the desert into scalable solutions for people everywhere.
BGU at a glance:
20,000 students | 800 senior faculty | 3 campuses | 6 faculties: humanities & social sciences, health sciences, engineering sciences, natural sciences, business & management, and desert research.
