A year after Yonkl Reservoir (Eastern Highlands Province, Papua New Guinea) had been completed, a su1wy was conducted among people found fishing at the shore. Rod and line was used in 99% of the reported fishing trips. On an average 0.42 kg of fish was caught per person per trip. The average catch per hookhour was 0. 033 kg of the past fishing trips, and 0. 021 kg of the on-going fishing trips. The first half of the year during which interviews were conducted the catch was composed only of Cyprinus carpio and Oreochromis mossambicus. In mid-1992 Tilapia rendalli appeared in the catch, and six months later this species was responsible for 48% of the weight of the dally catch. The total catch from the reservoir for the year 1992 was estimated al 40.2 tons.
