In this study, five Neolissochilus soroides and Channa lucius were surgically implanted with a unique coded acoustic transmitter to observe the habitat utilisation and movement activity in Tembat Reservoir after the inundation process. All of the individuals were released into the transition zone of the reservoir and observed using passive and active acoustic tracking devices ARTICLE INFO from April to December 2018.

The most prominent four (71.19%) components with eigenvalues modification is the multidimensional greater than 1 for N. soroides and C. lucius, change of the natural water body in the respectively. Three most important habitat catchment (Zeiringer et al., 2018). The parameters for N. soroides were the size of aquatic landscape is usually transformed river (r = 0.97), existence of canopy cover (r into an open system with less or no canopy, = 0.77), and substrate type (r = 0.79).While, depending on the volume of the water. for C. lucius were mesohabitat type (r = It can be divided into three longitudinal 0.79), distance to riffle (r = 0.97), existence systems: riverine (lotic), transition, and of canopy cover (r = 0.90), and elevation lacustrine (lentic) zones (Schmutz & Moog, (r = 0.90).

The modification can also involve analysis for both species revealed two active stratification of the water column in deeper hours of movement at dusk and dawn for areas where anoxic conditions can occur both species.

In this development. newly developed lentic habitat, the fish assemblage can be modified qualitatively Keywords: Fish movement, fish telemetry, habitat use, and quantitively through extermination of hydroelectric impacts, post-inundation native fish species, reduction of habitat diversity, increasing densities of indigenous INTRODUCTION species, and introducing non-native species Inundation of water catchment areas in the (Zhong & Power, 1996). In addition, the tropical rainforest for hydroelectric stations impoundment of downstream areas can is known to have a devastating effect on the influence the fish assemblage through environment. Many studies have described changes in temperature, flow regime, the ecological implications, and the effect is sediment loads, and turbidity of the area more pronounced in tropical water catchment (Li et al., 2016). Although in-depth studies areas (Fearnside, 2014; Huang & Li, 2016). of impacts on the ecology of aquatic fauna These areas are often subject to hydroelectric have been widely discussed, there is still a power development due to geographical need to understand more about the utilisation landscape and topographic suitability of habitat and movement of fish fauna in a (Zafirah et al., 2017).

Moreover, its sedentary found in Southeast Asia, particularly the characteristics are a great indicator of Malay Archipelago and Borneo.
