Description FORV Sagar Sampada collected a good number of oceanic squids belonging
to several families from the Indian EEZ and contiguous seas. Of these, the most
important species was the purpleback flying squid Symplectoteuthis oualaniensis
which forms a potential oceanic squid resource. This species was caught in pelagic
trawl at depths up to.200-250 m from surface in the oceanic areas. Though the squid
is known to be distributed throughout India's oceanic waters, it frequently occurred
in comparatively more abundance, up to 318 squids per haul, in the northneastem
Arabian Sea. There was wide variation in the size of this squid (from 20 mm to 472
mm), the largest individual weighing 4.5 kg. The diamondback squid Thysanoteuthis
rhombus, the largest specimen of which measured 585 mm in length and 5.3 kg in
weight, was also caught from a few stations. Besides these large species, several
others belonging to families such as Onychoteuthidae, Histioteuthidae, Enoploteuthidae
and Cranchiidae are also distributed in the EEZ. A large number of oceanic squids
were collected at night, which is indicative of their diel vertical migration towards
surface layers during night hours.
