  Analysis (VPA) of <I>Parailia pellucida</I> was studied with samples collected 
  from commercial artisinal fishers for 13 consecutive months. The length-frequency 
  distribution of the 1722 <I>P. pellucida</I> showed that the smallest and largest 
  specimens were 3.8 and 10.2 cm TL, respectively (mean = 6.11cm&plusmn;0.81) 
  with 1 mode at 5-6 cm TL. The weight ranged between 0.3-7.5 g (mean = 1.4 g&plusmn;1.04). 
  In the whole 13 months, there was significant heterogeneity (X<SUP>2</SUP> = 
  21.09, df = 12, p&lt;0.05) with females dominating. Estimated values of length 
  and age at sexual maturity L<SUB>m </SUB>and t<SUB>m</SUB> were 6.3 cm TL and 
  1.39 year<SUP>-1</SUP>, respectively. The sizes attained by the <I>P. pellucida</I> 
  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<SUB>o</SUB>), 
  length at age zero (L<SUB>o</SUB>) and potential species longetivity (t<SUB>max</SUB>)were 
  -0.29 year, 1.81 cm TL and 4.76 years.
