Umami Sustainable Seafood Inc. Announces Purchase of Live Bluefin Tuna and Agreement to Acquire Additional Farming Capacity in Croatia

SAN DIEGO, March 9, 2011 - Umami Sustainable Seafood Inc. (OTCBB:UMAM) ("Umami" or the "Company")
today announced that following an acquisition of about 150 metric tons of
live bluefin tuna in Croatia from an unrelated third party (hereinafter: "the
Vendor") in January 2011, the Company has also concluded an agreement with
the Vendor that secures the transfer of the Vendor's current tuna farming
concessions in Croatia to Kali Tuna, Umami's Croatian subsidiary, subject to
the formal approval of the respective Croatian Authority. These concessions
relate to 1,500 metric tons of farming capacity and respective farming
licenses.

The additional concessions would increase Kali Tuna's approved farming
capacity in Croatia by approximately 45%, from 3,300 metric tons to 4,800
metric tons of capacity. As part of the agreement on the transfer of
concessions, Kali Tuna has agreed to purchase certain bluefin farming assets
from the same Vendor once Kali Tuna receives final approval for the
concession transfer. The concessions and assets are located in close
proximity to Split, Croatia, and are less than 100 miles from Kali Tuna's
present operations in Kali, Croatia. Total consideration for the concessions,
the related farming assets and the 150 metric tons of bluefin tuna will be
approximately $4.9 million.

In announcing the acquisition, Oli Steindorsson, Chairman and CEO
commented: "The additional concessions which we are acquiring, subject to the
local county's formal approval, are an integral part of our plan to increase
capacity in Croatia in order to achieve higher levels of sustainable
production of bluefin tuna. We purchased live bluefin tuna to effectively
secure the acquisition of the farming concessions and assets, facilitating an
increase in Kali Tuna's level of sustainable production. The locations of the
new concessions are in the protected waters of the Adriatic Sea and the
physical distance is close enough to our present Kali facilities for
efficient operations and far enough to allow geographic diversity of
locations."

Mr. Steindorsson concluded: "Coming on the back of our acquisition of
Baja Aquafarms in Mexico, the purchase of the additional concessions in
Croatia reflects Umami's commitment to building our sustainable production
base for bluefin tuna and to growing into one of the world's leading
participants in sustainable aquaculture. The additions to our capacity should
allow Umami to achieve over 5,000 metric tons of sustainable production by
fiscal year 2013."
