Description Juveniles of ginger prawn, Metapenaeus kutchensis (George, George and Rao, 1963), form monsoon fishery in shallow
estuarine waters of the Little Rann of Kutch. The catch data were collected from Tikar, Mandrakhi, Cherowari and Surajbari
landing centres during 2004 to 2009. The annual average catch was 2406 t, of which the bulk was contributed by Mandrakhi
and Tikar. The catch correlated well with the amount of rainfall (r = 0.97). The length-weight relationships were expressed
as: Log W = -2.367 + 3.1204 log TL for males (r = 0.81) and Log W = -2.868 + 3.7098 log TL for females (r = 0.88). All the
water quality parameters including ammonium nitrogen, nitrate nitrogen and phosphate phosphorus were within safe limits
and congenial for growth of ginger prawn juveniles and post-larvae. The water and sediment bacteriology revealed that both
proteolytic and lipolytic bacteria were present in considerable quantities for efficient recycling. The chemical and biological
parameters of water apart from monsoon rains, appear to contribute to the rapid growth of this species from post-larvae to
juveniles.
