    Abstract
    Research on densities of bilih fish (Mystacoleucus padangensis Blkr.) and growth patterns in the waters of Lake Toba Haranggaol had been carried out in December 2014 to January 2015. The purpose of this study was to determine the pattern of growth and determine the density of bilih fish (Mystacoleucus padangensis) in each station based on the difference of activity in the waters of Lake Toba Haranggaol. Sampling was conducted using "purposive sampling" method at four locations based on community activities such as Cage Aquaculture, Pier, Tourism and Free Activities. Fish was taken using doton with a size of 25 x 2 m. The results obtained showed bilih fish (Mystacoleucus padangensis) with the highest population density value was found in floating cages station with a value of 2.37 ind / m2 and the lowest on the dock station with a value of 1.44 ind / m2 . Gonad maturity level (TKG) IV differed at each station. Stations 1 and 4 obtained TKG IV and stations 2 and 3 obtained TKG I, II, and IV. The value of light penetration, TSS, COD, ammonia, and phosphate were very strongly correlated to the density of bilih fish (M. padangensis).
