Description The amphipods collected from the deep scattering layer (DSL) of Arabian Sea
and Bay of Bengal belonged to 13 families viz. Cystisomatidae, Oxyccphalidae,
Pronoidae, Anapronoidae, Vibiliidae, Lycaeidae, Lycaeopsidae, Phronimidae, Platyscelidae,
Phrosinidae, Scinidae, Lanceolidae and Hyperiidae. The amphipod
abundance showed wide fluctuations. Oxyccphalidae, Phronimidae and platyscelidae
were widely distributed in both the shelf and oceanic regions of the west coast. In the
east coast Phronimidae and Phrosinidae were widely distributed in the shelf and these
two families together with Vibiliidae and Platyscelidae were widely distributed in the
oceanic regions. In this investigation only Phronimidae was found to have wide
distribution in the shelf and oceanic regions of both the Arabian Sea and Bay of
Bengal. Vibiliidae and Phrosinidae showed aggregation in the oceanic region and
these two together with Lycaeidae showed such a trend in the shelf of the west coast.
Similarly in the east coast while Lycaeidae and Pronoidae showed aggregation in the
shelf, only the former showed that trend in the oceanic region. While Cystisomatidae
had a moderate distribution in the shelf of both the coasts and in the oceanic region
of the west coast, it had a poor distribution in the oceanic region of the east coast.
Vibiliidae and Oxycephalidae were moderately distributed in both the shelf and
oceanic regions of the east coast. AH other families of amphipods had a poor
distribution.
