Fishing is one of major local industry in Malaysia especially in rural area. However, the rapidly increasing price of fuel is seriously affected to the local fishing industries. At present, the use of petrol (gasoline) outboard engine in small-scale fishing boat have become popular choice instead of inboard diesel engine due to several advantages such as high speed, low weight, ease to install and space saving. However, petrol outboard engine has a high fuel consumption compared to diesel engine. Nevertheless, installing diesel engine with conventional submerged propeller in existing small-scale fishing boat is not economic since it requires major hullform modification and extra expenditure. Thus is due to the fact that most inshore fishing boats are of semi-planning hullform and free from appendages such as skeg and rudder stock. In addition, conventional propellers coupled to inboard diesel engines suffer on propeller losses. This paper describes a study to reduce fuel consumption by introducing a combination of diesel engine and surface piercing propeller (SPP).
    • It has been shown that a fuel saving gain than outboards with acceptable speed performance. The fuel consumption analysis reveals about 40 % fuel saving can be gained as shown inFigure 2.Figure 2: Fuel consumption curve comparison [5]. From the results, it can be a turning point for inshore fishing to adapt a diesel engine instead remains with outboard.

Presently, Malaysian small fishing boats use petrol (gasoline) outboard motor. However, petrol outboard engines have higher fuel consumption compared to diesel engines. The higher relative cost of petrol adds to the problem. Efforts to introduce diesel engines to the small boats are hampered by the size of the engines and the suitability of propellers. This paper describes a study to determine the potential using combination of surface piercing propellers and diesel engine in small fishing boats. An analysis of fuel consumption reduction will be presented, together with an economic feasibility study. This economic review will identify the fuel savings gained as to determine the simple payback period on the initial cost and conclude the viability of using the system in terms of fuel and overall monetary savings.

    Since the red grouper was declared overfished, the Gulf of Mexico Fishery Management Council must prepare a rebuilding plan considering the following alternative management policies: a Total Allowable Catch (TAC), 5-month season closure, 1800-pound trip limit, and a 50-fathom longline boundary. This study was aimed at evaluating the effects of proposed policies for rebuilding the red grouper... [Show full abstract]

      This study uses the traditional cost-benefit analysis to estimate the viability of commercial fishing in Botswana, using the Boiteko Syndicate in Shakawe, Botswana. The Net present Value (NPV) and Benefit Cost Ratio (BCR), indicate that commercial fishing, as practiced by the Boiteko Syndicate, is commercially viable and thus, should be encouraged and supported. The findings are supported... [Show full abstract]

        During the last few years, advances in completions and sand-control technology have enabled development of many high-end technologies that allow complex operations to be conducted. During the life cycle of a well, one of the key operational goals is to maximize the well's net present value (NPV). Typically, the majority of the well completion budget is allocated to the drilling phase. If,... [Show full abstract]

          Biological changes in Pacific whiting (Merluccius productus) and corresponding production yields were used to model a vertically integrated fishery from harvest through processing. The seasonal bioeconomic programming model incorporated stock dynamics with the interactive economic effects of intrinsic fish quality, the harvest schedule, and quota allocation between heterogeneous user groups....
