Abstract
The length-weight relationship and condition
factor of some finfish species from Luubara creek: Chrysichthys
nigrodigitutus Ethmalosa fimbriata, Pseudotolithus elongatus Mugil cephalus and
Pellonula leonensis were studied for a period of one year. A total of 706
fish specimen of C. nigrodigitatus (97) P. elongatus (261), M.cephalus
(71), E. fimbriata (193) and P.leoneengis
(64) were measured for total
length and weight. The fish samples which were caught during the study
period using gillnet, castnet, trap (kara and metal drum traps) and longline.
The length-weight regression statistics was obtained using
FISAT (FAO-ICLARM stock assessment 7001s). The growth coefficient obtained
for the five species ranged from 0.1307 to 2.3995 for C. nigrodigitatus,
0.0386 to 2.3985 for E. fimbriata, 0.428 to 3.6449 for M. cephalus
0.0730 to 3.0308 for P.leoneensis. Three species C. nigrodigitatus,
E. fimbriata and P. elongatus have b-values of 2.3995, 2.3985 and 2.9908
respectively meaning that the values are less than 3(b<3): implying that
they are negatively allometric in growth. M. cephalus had a b-value of
3.6449 (b>3) which indicates positive allometric growth pattern. P.
leonensis had a b-value of 3.0308 which is equal to 3 (b=3) and indicating
an isometric growth pattern. The condition factor (K) value ranges from
0.101-2.261 (mean K-0.7261) for C. nigrodigitatus, 0.721-0.949 (mean
k=0.8726) for E. fimbriata, 0.337-0.923 (mean k=0.3925) for M.
cephalus, 0.7-0.912 (mean K=0.7377) for P. Elongates and 0.504-0.990
(mean k = 0.8233 for P. leoneensis. The condition factor for four of the
species were in suitable range that guarantee good condition.
