Population Dynamics of the Fiddler Crab <i>Tubuca rhizophorae</i> (Tweedie, 1950) in the Mekong Delta, Vietnam.

ABSTRACT: This study investigates the population characteristics of the fiddler crab, Tubuca rhizophorae, at two sites in the Mekong Delta, Vietnam. Monthly samples were collected from March 2024 to February 2025 in Dong Hai, Bac Lieu and Dam Doi, Ca Mau. Population parameters, including asymptotic carapace width (CW_∞ = 23.18 mm), growth rate (K = 0.68/year), longevity (approximately 4.41 years), total mortality (3.22/year), natural mortality (1.55/year), fishing mortality (1.69/year), exploitation rate (0.52/year), and carapace width at first capture (CW_c = 13.60 mm), were estimated. The results indicate that the T. rhizophorae population exhibits rapid growth, relatively short longevity, and is subject to significant fishing pressure; the exploitation rat
