Umami Sustainable Seafood Inc. Announces Estimates of First Half Sales

SAN DIEGO, December 9, 2010 - Umami Sustainable Seafood Inc. (OTCBB:UMAM) ("Umami" or the "Company")
today announced that it expects to have harvested approximately 1,400 metric
tons of bluefin tuna, with a sales value of approximately $25 million, for
the six months ending December 31, 2010.

The Company expects to harvest approximately 400 metric tons of bluefin
tuna at its Kali Tuna operation in Croatia and 1,000 metric tons at its Baja
Aqua Farms operation in Mexico. Of the 1,000 metric tons at Baja,
approximately 650 metric tons were harvested prior to Umami's completion of
the acquisition of Baja. Umami's interest in those sales will be included in
the income statement under earnings from investment in unconsolidated
affiliates for the period. Those sales made after completion of the full
acquisition of Baja, estimated to total 350 metric tons, will be included in
Umami's sales and operating results for the six months ending December 31,
2010.

The Company also announced that it expects to end the six months ending
December 31, 2010 with approximately 5,000 metric tons of biomass which are
available for sale or further growth at its farming facilities.

In announcing these results, Oli Steindorsson, Chairman and CEO
commented: "Following the announcement of the closing of the Baja acquisition
last week, it is gratifying to see our harvest generating significant cash
flow to assist in the operational expansion of our business, as well as
strong operating results. We believe that the acquisition of Baja has
elevated our bluefin operations to higher standards and we will continue to
harness the benefits of our sustainable operating platform to generate
superior financial results."
