Description 2217-2222
The population dynamics of Uca
sindensis were investigated for the first time in Pohl port mangrove in
north of Persian Gulf using Length- Frequency analysis. Nine 0.5 m2 quadrates
were randomly sampled during low tide periods every month, from October 2009 to
September 2010. The quadrates ran in three substrate, sand, silt and muddy flat,
in order to sample of total substrate. A total of 710 crabs, 343 (47.7%) males
and 367 (52.3%) females, were sampled. Sex ratio, von Bertalanffy growth
parameters, recruitment pattern, growth performance and natural mortality
coefficient were calculated and also Length-based stock assessment using FISAT
software package. There was not different significant in sex ratio (1:1.069).The
CW, Asymptotic Length(L∞) and Growth curvature (K) and φ were
3 to 14.5 mm, 17.3 mm, 0.33 year-1and1.98 in males and 4 to 12 mm, 16.28 mm0.36
year-1 and 1.94 in female, respectively. The natural mortality coefficient and was
estimated to be 0.95 for males and 1.05 for females. The growth of U. sindensis
follows the seasonality oscillating VBGF typical of soil temperate. Recruitment
pattern shows seasonal recruitment pattern in total population. In conclusion,
descriptive of life U. sindensis has a k-selection strategy that in die
young, reproduce early, live last and high mortality.
