Israeli Team Nears Solution to Bluefin Tuna Crisis

An Israeli research team is on its way to finding a solution for saving the world’s dwindling populations of costly bluefin tuna.

Thunnus thynnus, commonly known as the bluefin tuna, weigh hundreds and sometimes thousands of pounds each, and, fetching prices of up to $1,000 for a single kilogram, they constitute one of the most valuable fish markets worldwide.  The tuna is a highly prized delicacy popular for sushi and other Japanese dishes, and is currently over-fished due to strong demand from markets in Europe, America, and especially Japan, which consumes 80% of the bluefin market. Though not officially classified as endangered, the International Commission for the Conservation of Atlantic Tunas reported in 2009 that the tuna population has declined dramatically over the last 40 years, by 72% in the Eastern Atlantic, and by 82% in the Western Atlantic. The tuna is already extinct in the Black Sea.

Concerned by these statistics, the European Union gathered international research teams with participants from countries including Germany, Spain, Greece, and Israel to work towards ensuring the survival of the fish species, reported nocamels.com. The goal was to develop an effective process of aquaculture that would allow breeding of the tuna on fish farms, leaving the wild bluefins free to reinforce their numbers at sea. But domestic breeding of the tuna has proved challenging because of the tuna’s complex lifestyle, slow growth, and late maturity.

Following a decade of research, the Israeli team, under the leadership of Dr. Hannah Rosenfeld, who also heads Israel’s National Center for Mariculture, has advanced tuna-breeding success worldwide.  The Israeli scientists captured specimens during the tuna’s annual migration to the Mediterranean Sea to spawn. In captivity, the adult tuna was bred, and the young have now advanced to adulthood.

The success is only partial, because the fish spawned in captivity have not been re-bred. But the team looks to come full circle with the breeding, which would solidify a viable solution to the tuna problem.”We hope to make progress now and advance to the next stage of stepped up research, where we will be able to close the life cycle of the domesticated fish” said Dr. Rosenfeld to Israeli newspaper Ma’ariv.  “Once we achieve this goal, we will not be dependent any more on wild fish and we will be able to set in motion the recovery of the global population of this endangered species.”

    Jewish Men Pass Jimmy Kimmel Social Experiment, Rescuing ‘Spongebob’ in Distress (VIDEO)

    Two Jewish men were the only unwitting participants in a social experiment conducted by Jimmy Kimmel, for his popular TV show. As part of a candid-camera-like sketch featured Monday night on Jimmy Kimmel Live, the host devised different street scenes to observe human behavior — in particular, to see how long it would take people walking down California’s bustling Hollywood Boulevard to notice and interact with others in distress. One scene involved a man in a Spongebob Squarepants costume who had “fallen down” on the sidewalk and needed help […]

In an interview with the U.K. Independent she added that the trauma should make Jews more empathetic to others who have also experienced hatred. “Sometimes it can be subverted to fearmongering and like ‘Another Holocaust is going to happen,’” the Israeli-American star said. “We need to, of course, be aware that hatred exists, antisemitism exists against all sorts of people, not in the same way.

    A Righteous Gentile Navigates the Sharkpool of Washington’s Middle East Correspondents (REVIEW)

    The Tribalist, by Louis Marano, is ostensibly a work of fiction but at its core a kind of love song by a gentile journalist for the State of Israel, and especially its secular Zionist core. (Because of the relentless attacks by left-wing polemicists on Israel’s allegedly “messianic” fringe, it’s often forgotten that most of Israel’s founders and all its leaders have been secular Zionists.) The author, the product of an Italian-American family in Buffalo, served two tours of duty in […]
