Tunas are commercially important food fishes
exploited from all the world oceans. Of the 9 species
contributing to the Indian tuna fisheries, yellowfin
and bigeye tuna grow to big sizes, and with superior
meat quality have high export demand.
Identification of these tuna species are
comparatively easier in fresh condition than the iced
or frozen condition due to discolouration, fin and
skin damage during handling and storage process.
In such cases certain internal characteristics such
as length of air bladder, liver shape and striation
are used. Misidentification of yellowfin and bigeye
tunas occurs in several cases. The present study is
based on field observations at Cochin Fisheries
Harbour and uses an easy field identification key
for yellowfin and bigeye tuna based on external
characteristics developed by Itano (2005) and IOTC
(2013). Bigeye tuna are landed stray numbers along
with yellowfin tunas, at Cochin Fisheries Harbour.
