Abstract
The present study determined the fish species composition and described the length-weight relationship (LWR) of fishes in Tigum River, Iloilo, Philippines from April 2015 to March 2016. Ten (10) fish species from eight families were identified – with Poecilia sphenops as the most numerous (47.0%), followed by Oreochromis niloticus (38.2%). Linear regression analyses of the LWR showed a significant relationship between length and weight of fish – with r2 greater than 0.9 for the seven of the 10 fish species sampled – indicating that fish weight may be predicted from the length, at least within the range of the fish lengths recorded.
