摘要

Distribution, abundance and morphometrics of Uca sindensiswere studied in a mangrove mudflat area of Pakistan. Crabs were collected on a monthly basis during low tide periods from March 2001 to February 2002 from the Korangi creek (24 degrees 79'N/ 67 degrees 20'E) through transect and quadrat method from low tide level to high tide level. Spatial and seasonal differences in density m(2) distribution, with higher densities at high tide level were observed. Density of crabs varied in between 0 and 64 m(2). Unimodal size frequency distribution revealed the normal distribution of crabs. Size of the male crabs was significantly larger (t = -6.04 P<0.005, df=157) than that of female crabs indicating sexual dimorphism. Morphometric analysis of different variables (carapace width, length, cheliped length, width and depth, abdominal width and length and in last Sinistral and Dextral state of enlarged cheliped in male crabs) were recorded to compare their allometry. Relationship that mostly indicated the positive allometry in female was abdominal width and carapace width (Ab.W vs. CW) and enlarged Chela width to carapace width (Chl. W vs. CW) in male was observed.
