The analysis was made for the three species and also for the two vessel types. The effort was standardized ...
    • Gender roles in fishery planning and projects. The case study of coast region in Tanzania 

      Msigwa Chando, Catherine (Master thesis; Mastergradsoppgave, 2002-05-31)
      Women play crucial roles in fisheries, particularly on the post harvest level. Despite this, they are noticeably absent from the discussion of many development programmes in fisheries. The focus is mainly on the needs and interests of men, neglecting women. Women are hardly involved in the planning and decision making or in the implementation and management of the projects. Therefore this study ...
    • Users' attitudes toward fisheries management on Lake Zeway, Ethiopia 

      Ali, Abdurhman Kelil (Master thesis; Mastergradsoppgave, 2002-06-03)
      A resource management system combines a set of regulatory scheme within a particular resource to achieve a management outcome. The effectiveness of these regulatory measures depends on the support gained from the resource user group and the way they themselves define their problem, their involvement in the decisionmaking process, in installing and enforcing the regulations. Through semi-struct ...

Two fishing fleets harvest hake, these are trawlers and longliners. In this study, the focus has been on the biological and economic characteristics of two different fishing methods. The Pella and Tomlinson surplus production model was ...
    • The economic development of the kapenta fishery Lake Kariba (Zimbabwe/Zambia) 

      Madamombe, Loveness (Master thesis; Mastergradsoppgave, 2002-06-07)
      Kapenta (Limnothrissa miodon) was introduced from Lake Tanganyika into the man-made Lake Kariba, where it now supports a large and viable fishery for Zimbabwe and Zambia who share the lake. The challenge for this paper has been to investigate whether the viability of the kapenta fishery is dependent upon biological factor or economic parameters. The Pella and Tomlinson surplus production model ...
    • The evaluation for the fisheries resources in Bohai Sea 

      Zhang, Chunrong (Master thesis; Mastergradsoppgave, 2002-06-12)
      Fisheries in Bohai Sea occur in an ecosystem, with different provinces conducting fishing activities on different species using different gears. Coordination of government actions continues to be a problem, as there exists many contradictions between different sectoral planning approaches. With the absence of a holistic institutional framework of management mechanism, coastal and marine resources ...

    • A bioeconomic model for Uganda's Lake Victoria Nile Perch fishery 

      Kyomuhendo, Peter (Master thesis; Mastergradsoppgave, 2002-12-12)
      After an evaluation of this Nile perch fishery for the period 1986 – 2000, when it constituted more than 60% of the catch, it is evident that a severe over fishing problem exits and that the fishery has never been managed for economic efficiency. All economic rent from this fishery has been and continues to be dissipated. The effort in 2000 is 64% higher than that required to take MEY and 44% ...

    • Integrated Coastal Zone Management (ICZM). The allocation of space in Norwegian aquaculture - from local lottery to central planning? 

      Sønvisen, Signe Annie (Master thesis; Mastergradsoppgave, 2003-05-22)
      Resource management in the coastal zone involves a large number of stakeholders and resource users, from traditional fishermen and recreational housing owners to state and municipal government. The aim of this study is to show how spatial scarcity in Norwegian aquaculture is not solely a technical definition, but scarcity also depends upon the social context in which it operates. That is, what ...

The different adjuvanted vaccines were administered by intraperitoneal injection (i.p.) ...
    • Consumption of salmon. A survey of supermarkets in China 

      Wang, Lingling (Master thesis; Mastergradsoppgave, 2003-05-28)
      To keep up with the recent trends in consumer demand for salmon product in supermarkets, an understanding of the relationship between consumption and variation of lifestyle is needed. The present paper seeks to address this question by hypothesizing that consumption is strongly influenced by consumers’ sociodemograhic status, experience of salmon, beliefs with salmon’s attributes and preference ...
    • Bioeconomic analysis of artisanal marine fisheries of Tanzania (Mainland) 

      Berachi, Isaac Ghebregziabher (Master thesis; Mastergradsoppgave, 2003-05-28)
      Artisanal marine fisheries of Tanzania involve the majority of the coastal population whose survival is entirely dependent on the coastal fishery resources. In this paper the artisanal sector of the marine fisheries for the period 1987 -2000 is analysed by applying Gordon-Schaefer Surplus Production Model on time series of total catch and standardised effort. Static reference points such as open ...
