Sepik River Fish Stock Enhancement, Papua New Guinea
1993Also available in:
No results found.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. -

1993Also available in:
No results found.From August 1991 to August 1992 a fisheries survey of lower order streams of the upper Purari River, Papua New Guinea, was undertaken as part of the Sepik River Fish Stock Enhancement Project. The aim of this survey was to get general information on fishes and fisheries in the upper Purari and to get information on the biology of the introduced rainbow trout. -

1989Also available in:
No results found.The actual landmass of New Guinea and the smaller islands lie between the two major plates, the stable continental plate of Australia to the south and the deeper Pacific basin to the north . The collision and subsequent northward movement of the former and the westward movement of the latter plate has created uplifted sections in the centre of the island thus forming the central highlands. These mountain ranges effectively create two different zoogeographic zones in the northern and southern reg ions of New Guinea. Freshwater fish fauna in the two regions are distinct, the southern species shown a resemblance to the fauna of northern Australian whereas those in the north show a high degree of endemism
