Length-weight relationships of fishes from tributaries of the Volta River, Ghana: Part II and Conclusion.

Slopes and intercepts of length-weight relationships obtained for 37 populations from the rivers Ott, Pru and Black Volta were compared using a one way analysis of covariance with fixed effects. Although no significant differences were obtained from this analysis, an ANOVA comparing the magnitudes of mean condition factors (W* 100+ SL'3) found 9 out of 37 populations significantly different at the 0.05 level. A Iwo-way nested ANOVA using all populations combined, however, did not yield any significant differences between the three rivers. Thus, pooling the data to obtain the results presented in Part I (see Entsua-Mensah et al. Naga 1995) is justified here.
