Abstract: Population structure, reproduction, age, Virtual Population Analysis (VPA) of Parailia pellucida was studied with samples collected from commercial artisinal fishers for 13 consecutive months. The length-frequency distribution of the 1722 P. pellucida showed that the smallest and largest specimens were 3.8 and 10.2 cm TL, respectively (mean = 6.11cm±0.81) with 1 mode at 5-6 cm TL. The weight ranged between 0.3-7.5 g (mean = 1.4 g±1.04). In the whole 13 months, there was significant heterogeneity (X² = 21.09, df = 12, p<0.05) with females dominating. Estimated values of length and age at sexual maturity L_m and t_m were 6.3 cm TL and 1.39 year^-1, respectively. The sizes attained by the P. pellucida are 3.73, 5.47, 7.62, 8.75 and 9.34 cm at the end of 3, 6, 12, 18 and 24 months of age, respectively. Estimated values for age at length zero (t_o), length at age zero (L_o) and potential species longetivity (t_max)were -0.29 year, 1.81 cm TL and 4.76 years.
