The research was conducted at the location of Lake Tondano, Minahasa District.The young payangka fish, locally known as nike fish by fishermen of the area. This study aims to determine the size distribution, length-weight relationships and to know the captivity growth in the aquarium. The research is expected to be a source of information about the fish of young payangka (Nike) and be able to contribute on the efforts of nike fish management in Lake Tondano for the future. Sampling is done by using a triangular shaped trap (sibusibu) with a length of 4m, width of 1.30m (top), and a mesh size of 0.5mm. The length frequency distribution with the size mode appeared most during the first of observation was in the range of 13.5 to 15.4 class size and changed in size in the third week of the 19.5-21.4 class sizes. Later in the fifth week the mode is in the range of 15.5-17.4 class size and changes in size in the seventh week at the range of 23.5-25.4 class size. The length-weight relationship of the study was showed by allometric growth (b = 2.70; b <3) which means the length increases faster than weight gain. Absolute weight growth of 0.2532g was recorded and absolute length growth of 10.12mm for 12 weeks was observed as well. Growth of a relatively large weight gained with value of 0.067mg occurs between the seventh week and the eighth week.
