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 Lm and tm 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 (to),
length at age zero (Lo) and potential species longetivity (tmax)were
-0.29 year, 1.81 cm TL and 4.76 years.}
