Description In the DSL fish biomass one of the dominant genus was Vinciguerria, represented
by three species such as V. nimbaria, V. attenuata and V. poweriae. The
occurrence of Vinciguerria was frequent in nortliwest and southwest area of EEZ at
varying depths. The average number per haul in Isaac Kidd mid water trawl (IKMT)
was 149 in day and 191 in night collection. Vinciguerria nimbaria has accounted
for more than 95% of the total catch of the genus. Its total length varied from 10-56
mm. The length weight relationship is log W = -5.5691 + 3.1676 log I. Invariably the
species fed on copepods, ostracods, cladocerans, appendicularians euphausiids, chaetognaths,
fish larvae etc. with variations in feeding intensity during day and night.
About 92 % of the catch belonged to mature fishes. The species spawns only once in
a year and the fecundity ranged from 140 to 770 ova in fishes of 34 - 55 mm total
length.
