|
| Yellowfin is the
second tuna species is terms of volume and popularity. They are found between 45oN and
40oS. They cover enormous distances around the globe, and all stocks mingle. It is a big
fish, which can swim at very high speed, which may be one of the reasons why in some
areas, dolphins and large full-grown yellowfin swim together. Through extensive measures
from the side of the tuna industry, and the creation of some very good monitoring
programs. Fortunately the volume by-catch of dolphins has become insignificant now in
relation to the its natural mortality, and was below 500 dolphins on a global basis. Product Characteristics: In cooked form the yellowfin meat tends
to have a to very light yellow/brown color. The structure of the meat is quite firm, and
the taste is mild. If the fish gets larger then 10-15 kgs the meat tends to become
slightly darker and somewhat dryer. The large size of the yellowfin make it well fit for
solid pack in cans. |
| Future
Supply: Scientific analyses suggest that yellowfin is exploited to its optimum in the
Eastern Pacific ocean, and also in the Western Pacific there will not be any significant
growth in volume for the future. In the Indian Ocean exploitation leaves little space for
increase. The general concerns on yellowfin is that due to increased catches of
baby-yellowfin (especially in the Atlantic, Indian Ocean and Western Pacific), the stocks
might suffer on the long term.
