The present study reports on length-weight relationships (LWRs) for 37 of the most
abundant fish species in the Lefini River basin, one of the largest right bank tributaries
of the Congo River in the Republic of the Congo. The study area comprised 12
stations along 103 km of the river. Each station was sampled during March 2007 to
August 2008 following standardized methods utilizing five monofilament gill nets of
10, 12, 15, 20 and 30 mm mesh size. Sample size, lengths, weights, LWRs, 95% confidence
intervals of a and b, coefficient of correlation r2 and growth type are provided
for each species. Values of allometric coefficient b of the LWRs (W = aSLb) ranged
from 2.556 for Synodontis nigriventris to 3.363 for Brycinus poptae. These results represent
the first study of length-weight relationships for fish species in a large affluent
of the Congo basin as a whole.
