idinium (5,48%), cerataulina (4,11%), aulacoseira (2,74%), hemiaulus (1,37%), dan scenedesmus (1,37%). hasil penelitian menunjukkan bahwa ikan yang tertangkap di danau laut tawar memiliki pola pertumbuhan alometrik negatif, yang artinya pertambahan panjang lebih cepat dibandingkan pertambahan berat bobot ikan tersebut. kata kunci : morfometrik, kebiasaan makan dan hubungan panjang berat ikan. abstract this study examines morphometrics, length-weight relationships and fish eating habits found in laut tawar lake, central aceh district, aceh province. sampling was carried out on september 8 to 29, 2018 using a 1 inchchi doran gillnet net with a length of 30 meters. 157 fishes were obtained, namely keperas fish (cyclocheilichthys apogon) with the highest abundance of 75.17%, tilapia (oreochormis niloticus) 14.65%, buntok fish (xiphophorus helleri) 6.37%, and kawan fish (poropontius tawarensis) as much as 3.82%. morphometric character identification results show; the total length of keperas fish is 8.46 cm, tilapia 6.72 cm, buntok 7.38 cm, kawan 7.45 cm; the standard length of keperas fish is 6.80 cm, tilapia 5.37 cm, buntok 6.00 cm, friend 6.27 cm. the results of the analysis of fish eating habits were 11 species of plankton consisting of synedra (34.25%), coconies (12.33%), aphanocapsa (12.33%), brachionus (10.96%), asplanchna (8.22%) , parasagitta (6.85%), peridinium (5.48%), cerataulina (4.11%), aulacoseira (2.74%), hemiaulus (1.37%), and scenedesmus (1.37%). the results showed that the fish caught in laut tawar lake had a negative allometric growth pattern, which meant that the length increase was faster than the weight gain of the fish. keywords: morphometrics, eating habits and length-weight relationship of fish.
