Operation of lift net is a potential utilization for fisheries in Aceh. Recently, the factors affecting the fishing catch by lift net units are unknown. The information of production factors affecting fishing catch by lift net is required in order to optimize the operation capture. This research aimed to describe lift net units, fishing catch composition, and lift net units optimization in Krueng Raya waters, Aceh Besar. This research had been done from June until July 2017 in Krueng Raya

... , Aceh Besar. The data were collected through questionnaires which were distributed to 30 respondents. The lift net units and fishing catch composition were analyzed by using descriptive method. Lift net units optimization was analyzed by using a multiple linear regression model. The result of descriptive analysis shows that lift net units in Krueng Raya consist of a boat, a lift-nets house which is used as a house for fisherman to take a rest, whereas the floor of the house is used for fishing operations. In one lift net boat, there are fish handler, chef and crew. The fishermen use lamp, roller, scoop, generator, and fish basket as fishing catch equipment. The fishing catch compositions of lift net units in Krueng Raya are Stolephorus sp (74,7%),Rastrelliger sp (14,4%), Decapterus sp (7,6%) and Euthynous sp ( 3,1%). The multiple linear regression analysis results, Y = -498,667 + 5,302 (X 1 ) -23,643 (X 2 ) + 19,661 (X 3 ) -20,478 (X 4 ) -0,130 (X 5 ) indicate that the production factors; the lamp capacity significantly affected fishing catch, whereas the amount of the fuel insignificantly affected fishing catch.
