    Preliminary Analysis of Stomach Contents of Various Fish Species from the Lower Order Streams in the Sepik-Ramu Basin and Identification of Vacant and Underutilised Trophic Niches

    This document provides an analysis of the stomach contents of nearly all species that were collected during the field trips in the Sepik-Ramu catchment area made from January 1988 - September 1989 (Van Zwieten 1990a) . The stomach contents analysed in this report are in general taken from fish that were sampled during the whole sampling period from all areas covered. The data presented are averages from all the specimens of a single species analysed; no attempt has been made to unravel differenc es in feeding behavior as reflected by stomach contents in different size groups of species. Variations in stomach contents of specimens of one species collected, from different rivers are yet to be analysed. Furthermore it is not possible, as yet, to say anything about seasonal changes in feeding. These aspects will be considered in separate publications. For our purpose the present level of analysis is sufficient: the identification of vacant and underutilised trophic niches in the lower order streams of the Sepik-Rarnu catchment.

    Summary of the geology, geomorphology, climate and vegetation of the Sepik and Ramu River catchments with notes on their relevance to fisheries
    PNG/85/001

    Also available in:

    This document provides background information for project PNG/85/001. A synthesis of knowledge of various aspects of the Sepik and Ramu River catchments is provided. The information is presented in relation to project objectives and activities. Most sections have been summarised from existing books and other information (quoted where relevant) but have been placed within the context of the Sepik and Ramu rivers and project PNG/85/001. The subjects covered here are relevant to fisheries related m atters and this is explained later in the Discussion section.
