U.S. Changes
Israeli Label
WASHINGTON (ZINS)
— On the eve of the Senate
vote on the sale of AWACS,
Sidewinder missles and
other supplies to Saudi
Arabia, the U.S. Customs
Service required a labelling
change on goods made in
Judea and Samaria.
Following the receipt of a
letter from the State De-
partment, the Custoins
Service ordered that goods
made in the administered
territories and shipped to
the U.S. could no longer be
marked "Made in Israel."
They must now be marked
"Made in Israeli - Occupied
West Bank."

REHOVOT (JNI) — Is-
raeli agro-meteorologists of
the Volcani Institute have
developed a method to
measure "the thirst of
trees." With two needles in-
serted into the tree trunk to
measure . temperature and
thermic waves, the scien-
lists calculate rate of inter-
nal water evaporation.
Tested successfully in ir-
rigating Israeli avocado and
citrus trees, as well as in
Australian and Canadian
forests, the method will
soon be applied to cultivated
crops, such as Israeli cotton.
produced in a local desali-
nation plant.
"We think that on one
quarter of an acre a fish
farmer can earn something
in the neighborhood of
$10,000 per year," says
Gordon, 44, who lives with
his-wife and three children
on nearby Kibutz Yotvata.
The mariculture project
was started by Gordon, a
graduate of Hebrew Uni-
versity and Scripps Institu-
tion of Oceanography in
California, and a handful•of
scientists in 1973, as part of
Israel's search for an indus-
try besides tourism for
settlers in the sun-parched
south. Today there are 25
men and women working
with Gordon and more and
more scientists are being
drawn to the excitement of
the project and the Eilat
area which boasts the most
extraordinarily rich coral
reef in the world.
The focal point of the
research is the effort to
completely control the
reproductive -cycle of the
denise, a fish highly val-
ued on European dinner
tables. "We're able to re-
produce the denise in the
laboratory," explains Dr.
George Kissil, 38, an ex-
pert in fish nutrition who
immigrated from the
United States to Israel in
1969.
Besides the headache of
worrying about funding the
new facilities, Gordon notes
other challenges facing the
research crew: preventing
pollution of underground
freshwater reserves from
pumped-in seawater and
controlling oxygen levels in
the ponds, where a 500 per-
cent supersaturation of
oxygen could cause disastr-
ous fish kills. Another area
of concern is the poisonous
backlash of pond sediment,
which releases toxic chemi-
cals that can harm the fish.
The rqaticulture scien-
tists also have their eyes on
being incorporated into the
planned saltwater canal
project which will link the
Mediterranean Sea to the
Dead Sea mainly to produce
hydroelectric power. If
enough seawater to main-
tain 4,000 acres of desert
ponds were dropped into the
Dead Sea (taking into ac-
count evaporation), in addi-
tion to the amount already
planned to keep the Dead
Sea full, 3 percent more
electricity could be pro-
duced in the process.
Dr. Gordon believes the
prospect of the additional 3
percent has made Med-
Dead Canal authorities
more interested in includ-
ing fish ponds into the giant
canal project.
