Abstract

The length-weight relationship (LWR) and relative condition factor of the cyprinid fish, Tor tambra, from Tembat Reservoir, Hulu Terengganu, Peninsular Malaysia were studied from March 2016 to May 2017. T. tambra was selected for population dynamic study due to their conservation status, as well as their high commercial value. It was specifically categorized as Data Deficient by the IUCN and protected under the Wildlife Protection Act 1972 (Act 76) and the Perak Land Fisheries Act 1992. A total of 496 individuals had total length and weight ranges of 10.5–66 cm and 15–3280 g, respectively. The values of the constants (a) and the coefficient correlation (b) were determined from the length and weight data, which transformed into the linear equation log W = log a + b log L. These parameters were then fitted to the parabolic equation, W = aLb. The growth exponents (represented by ‘b’) for the fish varied from 2.591 to 3.340. The overall LWR equation for T. tambra (log W = 2.980 log L – 1.930) showed a negative allometric form of growth, indicated by the growth coefficient (b < 3), and the measurement of length and weight was significant and positively correlated (R2 = 0.95 at p < 0.0001). The results indicate that T. tambra growth was still in the normal range for freshwater fish. The relative condition factor index (Kn > 1) suggests that T. tambra individuals in Tembat Reservoir have good physical characteristics due to adequate food resources, and suitable habitats for expansion of the fish population. This study contributes to the knowledge base for T. tambra in Tembat Reservoir, and is crucial in terms of understanding the ecology of the reservoir for supporting conservation strategies, and the restoration and management of this species in future.
