Lake Matano, one of the lakes in the Malili Lake complex, is located in East Luwu District, South Sulawesi Province. Lake Matano is an ancient lake that is very deep with high biota and endemicity, including fish. The dominant endemic fish found on Lake Matano is  Telmatherina antoniae . At present, dominant alien fish which is Louhan fish is also found at this site. This paper aims to convey the latest information regarding population structure of the dominant endemic and alien fish in Lake Matano, namely relative abundance distribution, size structure (length and weight), growth patterns and gonadal maturity stages. Sampling was carried out in May and August 2016 at five stations. Fish were caught using gill nets with seven mesh sizes and installed for at least two hours. The relative abundance of fish at each station is determined based on the average of catch per unit effort, namely the number of fish caught per hour of gillnet installation(ind/hour), with growth pattern determined based on the length weight relationship, and the stage of gonadal maturity determined morphologically.  Telmatherina antoniae  and Louhan were found at all stations with the highest relative abundance in MT4 (Petea) and MT2 (Nuha), respectively. The length of  T. antoaniae  ranged from 64 to 105 mm (82.24 ± 0.61 mm) and weight 2.3 to 11 grams (5.62 ± 0.14 mm). The length of Louhan ranged from 51 to 185 mm (96.42 ± 3.36 mm) and weight from 2.5 to 102.6 grams (21.66 ± 2.36 grams). In May and August both  T. antoniae  and Louhan were found with gonadal maturity stage I to IV.
