Length-Weight Relationship and Condition Factor of the West African Fiddler Crab (Ucatangeri) in MboRiver, AkwaIbom State, Nigeria

Abstract

The length- weight relationship and condition factor of the West African fiddler crab (Ucatangeri) in Mbo river of AkwaIbom State, Nigeria, was conducted for 12 consecutive months (April, 2012 – March, 2013). Ucatangeri exhibits sexual dimorphism with sex ratio of 1.2:1.0 which was significantly biased in favour of males. The length-weight relationship showed negative allometric growth, b=1.6431. With an average of 9.61, Ucatangeri had a very high condition factor which is an indication of the well-being of the species.
