Synopsis (short abstract) During 1991-92 staff of the Sepik River Fish Stock Enhancement Project (SRFSEP) and of the Papua New Guinea National Department of Fisheries and Marine Resources conducted a series of surveys in villages located in the Sepik-Ramu catchment including at Y onki Reservoir (Eastern Highlands Province). These surveys are part of the study done by the SRFSE Project of the fishery taking place in the area to assess the importance of fishing and fish for the population residing in the Sepik-Ramu catchme nt in comparison with other economic activities and food. This was also done as a pre-stocking survey to gather base-line data upon which the future effects of stocking could be assessed. This report describes the way the surveys were conducted, the way the data were entered in a computer data base and the way the data were processed to be able to estimate relevant parameters such as the average income/household from various sources, the annual fish yield of men, women, boys, girls and of the wh ole community for each village or area surveyed.

    In 1987 the Sepik River Fish Stock Enhancement Project (SRFSEP) started its activities. During the first stage (1987 - 1990). studies on the fish stocks in the lower order streams and rivers in the Sepik-Ramu catchment area were conducted. Prior to this the fish stock and fishing activities of the Sepik flooplain only had been studied. It was concluded that the yield from the Sepik-Ramu catchment area was about 10% that which could be expected from a similar size river system elsewhere in Asia. Afica or South America. The fish stock is thoughuo be limited by the-absence of native fish species from freshwater fish families due to the geological history of New Guinea. and the very recent creation of the Sepik floodplain (approximately 6000 years ago), with consequently very few (3) native fish species which are well adapted to floodplain conditions (Coates 1990). It was proposed that new fish species should be imported and stocked in the Sepik-Ramu catchment area to increase the total fi sh stock as a means to increase the fish catches. nutritional status and income of the population residing in the catchment area. During the first phase of the project several species were identified as suitable in terms of expected impact on fish yields and expected minimum effect on native fauna. Actual stocking of newly imported fish species by the project started in June 1991.

    The survey on the ecology and biology of the fish fauna of the lower order streams in the Sepik-Ramu catchment commenced on January 1988 as subproject of the Sepik River Fish Stock Enhancement Project (PNG/85/001-09) with a sampling program that extended to mid 1989. This report presents some of the raw data obtained as a result of this survey. These are: data on number of specimens, total weight of specimens, size range and average size per species per sample.
