    abstract = {Growth patterns involving evaluation of Length-Weight Relationships (LWR) of four dominant fish species in Lake Ona, Southern Nigeria, were studied. The fish species,<I> Heterotis niloticus</I> (Osseoglossidae),<I> Synodontis nigrita (</I>Mochokidae),<I> Citharinus</I> <I>citharus</I> (Citharinidae) and <I>Heterobranchus bidorsalis</I> (Clariidae) were caught from 2001 to 2003, using varied fishing gears. The gears were-three bottom set and three surface set gill nets of mesh sizes 1.0, 3.0 and 5.0 cm, with each having a length of 25.0 m and a depth of 3.0 m; cast net with stretched mesh size of 6.4 cm; fish baskets, locally called manly; non-return value traps and a set of long-lines of length 35.0 m while Fish Aggregating Devices (FAD) and fences were equally used to aggregate fishes. The LWR was determined from the formula, W = aL<SUP>b</SUP> with the parameters a and b in that formula estimated through logarithmic transformation in the form Log W = Log a + b Log L. The Condition factor (k) was estimated from the relationship, k = W100/L<SUP>3</SUP>. The results obtained for LWR are presented for the four species and the values of the growth exponent &quot;b&quot; ranged from 1.92 to 3.04 for <I>H. bidorsalis</I>; 2.47 to 3.03 for <I>H. niloticus</I>; 1.39 to 2.11 for <I>C. citharus</I> and 1.01 to 1.97 for <I>S. nigrita.</I> Fish species in the lake were generally heavy and in good condition. Overall mean condition factor (k) were 1.21 for <I>H. bidorsalis</I>; 1.57 for <I>H. niloticus</I>; 2.40 for <I>C. citharus</I> and 1.60 for <I>S. nigrita.</I>}
