Description Studies on the fishery and biology of Metapenaeus kutchensis exploited off the northwest coast of India
during 1991-2000 indicated that the average annual catch of the species was 605 t, which contributed 4% to
the total penaeid shrimp landings at New Ferry Wharf in Mumbai. The species was found to feed on
polychaetes (45%), Acetes spp. (20%) and benthic crustaceans (14%). Dimegsional relationships between
total length, carapace length and total weight and tail weight are given for the two sexes separately. Size at
maturity was 103.1 mm for the males and 135.5 mm for the females. Fecundity and total length were
exponentially related by the equation F = 0.0000012*L 5.'. Wide continental shelf of the northwest coast in the
depth range of 40-80 m is the spawning ground, where the females emigrating from Gulf of Kutch spawned
from December-August at about bimonthly intervals. However, spawning during May-August contributed to
successful generation of the stock. It is construed that strong wind driven surface currents during monsoon
drift the larvae to the Gulf waters and subsequently to the Little Rann, where the estuarine conditions in the
adjoining creeks following monsoon rains create nursery. ground for the juveniles and support the seasonal
fishery there.
