Gender-bending fish could mean more food for Mideast
JERUSALEM (Reuters) -- Researchers in Israel, the West Bank and Germany are pursuing a project to transform female freshwater fish into males, a sex change they hope will put bigger fish on the dinner table.
Male fish are larger, grow faster and weigh about a third more than females, Mutaz Qutob, a Palestinian researcher involved in the experiments, said on Tuesday.
As part of a project with Hebrew University and Germany's University of Hohenheim, Qutob and his colleagues will inject food fed to newborn Nile Tilapia fish with compounds from plants found in the West Bank and often used as seasonings.
"This will have an effect on the fish's metabolic [structure] -- it may shift from female to male," said Qutob, a chemist at al-Quds University in East Jerusalem.
"This is a very important project. We are introducing a new food source for the Palestinians."
Scientists at Hebrew University had previously used synthetic steroids, which are regarded as less healthful, to create male fish, said Berta Sivan, a researcher at the Israeli school who helped found the project.
Palestinians in the West Bank import most of their fish from Israel and the coastal Gaza Strip.
But their consumption of fish, especially those from fresh water sources, has fallen in recent years due to rising costs and tighter Israeli travel and trade restrictions on Palestinians.
"We wanted to solve a fish-breeding problem in Israel and help bring in and promote fish consumption in the Palestinian Authority," Sivan said.
Cooperation between Israeli and Palestinian academics has been growing over the past few years.
"Israelis and Palestinians who cooperate on research tend to try to work harder during politically critical times," said Hassan Dweik, a co-director of the Israeli-Palestinian Science Organization, which helps find funding for such studies.
The IPSO this year received 74 proposals for academic projects to be conducted by Israeli and Palestinian researchers on topics related to agriculture, education, the environment and and medicine.
Israelis and Palestinians usually conduct their research separately and discuss it by phone or online due to the Israeli travel restrictions that also ban most Israelis from entering Palestinian-controlled areas.
From a science standpoint this is interesting. And if it can be made to work successfully it may be something that other nations look to do. I can see a number of potential applications here in the US along the coastlines, where a number of species are lower in total count than they were 10, 20 years ago.
But what is just as interesting is the way the the academics are working together. "Israelis and Palestinians who cooperate on research tend to try to work harder during politically critical times," said Hassan Dweik, a co-director of the Israeli-Palestinian Science Organization, which helps find funding for such studies. It is instances like this that show that there is hope for peace in the Middle East. That's not meant as a trite statement, rather, an acknowledgment that the science community between the two nations successfully can work together, when so many other parts of the respective communities are constantly at war with each other.
