Length-weight relationship of fishes in Sta. Ana Dam, Nabunturan, Compostela Valley, Philippines
Abstract
Length –weight relationship is important in describing several biological aspects of the species as well as beneficial in the success of in land fisheries like dams. Five thousand and twelve (5,012) fish individuals were collected from Sta. Ana dam, Nabunturan, Compostela Valley Philippines, from the period of March 23, 2017 – April 23, 2017. Using different catching gears like improvised lift net, cast net and hook and line. Species obtained were belonged to 5 families (Channidae, Cichlidae, Claridae, Cyprinidae, and Osphronimidae) with only one species per family. LWR was computed using the equation W=aLb, the value of “b” in length and weight relationship ranged from 2.476 – 2.830 lower than the Bayesian estimates. All fish species shows negative allometry which means that sample species become thinner as they grow larger, however, the correlation coefficients which values ranged from 0.885 to 0.963 in all five fishes showed a high degree of positive correlation between the standard length and total weight in all fish samples, furthermore species found were all introduced to the freshwater bodies of the Philippines. Findings of this study could be used as a valuable tool for fishery managers and improve fish stocks for the continuous supply of important fishes to the community.
