    As part of phase one activities undertaken under the Sepik River Fish Stock Enhancement Project an analysis of trout stocking practices in PNG was made. Work undertaken by the project with regard to trout has been restricted for reasons outlined below. This report is, therefore, preliminary in nature and may be modified as more field data become available. Trout is an exotic species in PNG and has been, and still is, stocked by various PNG authorities. Experiences relating to trout are, therefore, highly relevant to the Sepik River Fish Stock Enhancement Project.
