The Fecundity, Gonadosomatic (GSI) and Hepatosomatic (HIS) Indicies of Pellonula leonensis were
studied from May 2001 to April 2002 in the Lower Nun River, Niger Delta. The absolute fecundity (F) ranged
from 348 eggs (Total length, TL = 5.70 cm) to 4075 eggs (TL = 6.30 cm) (with a mean of 2080.20±92.82 eggs).
However, there was no significant seasonal variation in the fecundity. Relative fecundity ranged from 61 to 655
eggs/cm or 834 to 2828 eggs/g with overall means (±S.E) of 343±14 eggs/cm or 1410±51 eggs/g. Body weight
was the best predictor for fecundity with a correlation value of 0.57. There was absence of significant variability
in the mean monthly and seasonal GSI and HSI values indicating that P. leonensis had an all year round
reproductive pulse in the Nun River.
Key words: Fecundity, gonadosomatic, hepatosomatic, Nun, Niger Delta, Pellonula,
