Information on the feeding habit and length-weight relationship are crucial for fisheries management. Hence, the objective of the present study was to examine the feeding habit and length-weight relationships of the giant marbled eel Anguilla marmorata harvested from Brayeun River, Leupung sub-district, Aceh Besar District, Aceh Province, Indonesia. The survey was conducted from March to June 2017 (Rajab to Ramadhan 1438 Hijri Calendar). The sampling was done four times a month for three months on a dark night at new and old moons according to of lunar cycle (Hijri Calendar) for three months. A total of 38 eels were caught during the study and stomach content analysis showed that crabs and shrimp were the main food items for eel A. marmorata , while earth worms was a complementary food. This finding is indicating that A. marmorata is carnivorous. In addition, the length-weight relationship revealed that giant marbled eel had an allometric positive growth pattern, and the condition factors indicate the rivers are still in optimum condition and support fish life.
