Abstract Fish production and energy requirement in the traditional non-motorised gill net operations, in Vembanadu Lake, Kerala, India are discussed in this paper. Gillnetting is targeted at mullets and other estuarine resources and is operated from traditional two-men canoes of 5.5 m l oa, using paddling as means of propulsion. Fishing operations take place from November to July while during the other months it is suspended due to the presence of large quantities of macro-vegetation, drifting downstream. Mean number of daysof operation is 225 days. Mean catch per year per gill-netter was estimated to be 8.4 t of which mullets contributed 25.1% GER.t fish-1 was found to be 0.61 GJ making this one of the most energy efficient system. Nearly 98.92% of the GER is contributed by fishing gear and the balance by the fishing canoe. Energy efficiency ratio was 8.01 and energy intensity value was 0.125.
