Abstract

Tilapia is unique in that it continues to play a significant role in rural aquaculture, helping to improve farmers’ livelihoods. The aim of this study was to calculate the distance between specified morphological characteristics of the Tilapia fish and to determine the inter-population morphometric variability of Tilapia from various fish farms using truss-morphometric characters. A total of 50 samples were collected using fish nets from two selected fish farms in Negeri Sembilan namely Ulu Bendul & Kuala Pilah, in which 25 samples were caught from each farm. The samples then were soaked with fish tranquilizer to prevent it from moving, as for morphometric measurement, it was measured by using digital calipers. The study discovered that the two red tilapia populations had considerable morphometric variability. For both male and female specimens, multivariate analysis revealed substantial variations in morphometric features between the two populations of red tilapia. For both genders, the discriminant analysis plot revealed a clear distinction between two separate groups. There is no overlapping among the two sexes of two different populations is shown through canonical variate analysis plot. The results revealed that both Function 1 and Function 2 was successful in classifying the individuals into four distinct groups (Ulu Bendul Male (UBM), Ulu Bendul Female (UBF), Kuala Pilah Male (KPM), and Kuala Pilah Female (KPF)). Species identification is an important part of biodiversity monitoring. It was able to examine morphometric character variation and fish growth using the ANOVA and t-test. The DFA demonstrated that it was beneficial in categorising the samples not only into species groups, but also into sexes.
