    This report details the results of a consultancy carried out to develop carp feed using locally available ingredients for use at the Aiyura carp station, administered by the Fisheries Division of the Department of Primary Industry. Baseline data on agricultural feed resources of Papua New Guinea are summarized, and national agricultural and industrial by-products identified for potential use as carp feed at the Aiyura carp station and surrounding highland village fish ponds. The principle by-pro ducts identified are coffee pulp, pasture and arable crop waste, barley mill sweepings, livestock manure, copra cake and wheat mill run. On the basis of the feed resources available, a low-cost semiintensive feed strategy, using a combination of organic fertilization and supplementary feeding, is recommended for use at the Aiyura carp station and village fish ponds, and is fully described

    This report provides preliminary information on the biology and ecology of rainbow trout, Oncorhynchus mykiss, in highland streams of Papua New Guinea. The extent of success of its introduction and its implication on any future introductions of other coldwater fish species are discussed. The relevance of trout to the Sepik River Fish Stock Enhancement Project (SRFSEP) is based on the fact that salmonid trouts were the first exotic fishes to be introduced to Papua New Guinea for the purpose of enhancing fish stocks (West & Glucksman 1976). Furthermore, a follow-on project based on recommendations given by SRFSEP and dealing with stocking higher altitude rivers in order to improve fisheries in highland areas commenced in March 1993 (FISHAID; see Coates 1992). The presence of rainbow trout (presumably the only salmonid species established) may have considerable implications for future stocking of other coldwater fish species recommended by SRFSEP and undertaken during the FISHAID projec t.
