The purpose of this study was to examine the food habits and length-weight relationship of java barb ( Barbonymusgonionotus Bleeker) in Reubeeriver, Pidie. This study was conducted in August – September 2017. Ten samples fish were collected using purposive sampling method from the fishermen's landing sites along Reubeeriver. The digestive tract investigation showed that as many as 8 from 10 total fish sample were filled by food. Then, the food wasexamined and resulted in 6 types: moss liver (Antheceroptopsida sp.), bamboo roots pentung ( Dendrocalamusasper ), bilis fish (Mystacoleucus sp.), fig leaf ( Ficusracemosa ), jerbung shrimp ( Penaeusmerguiensis ), and worms (Lumbricusrubellus). The highest percentage of occurrence frequency and index of propenderence found on Moss respectively 100% and 57%, while the highest percentage of volumetric value obtained on shrimp (35%). The analysis of food habits indicated that Java barb (Barbonymusgonionotus) in Reubee River is a group of omnivores that tend to be herbivorous fish with a ratio of 3:1 gut length. The result of calculation of lenght-weight relationship on 50 fish samples depicted an average of 127.42 mm with an average weight of 56.46 grams. While the result of growth pattern calculation was allometrik negative with b value equal to 0.938 which means long growth was faster than weight fish body. The condition factor gave a normal pattern with a value of 107.16.
