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. Not Available |
