    How to build a timber outrigger canoe - BOBP/MAG/12 1993
    Also available in:
    No results found.

    Dug-out outrigger canoes, traditional fishing craft found from Madagascar in the west to Indonesia and the Pacific Islands in the east, are made from tree trunks of adequate diameter. But logs for construction of large canoes are becoming difficultto find and construction is consequently becoming more and more expensive. Dug-out construction also wastes a lot of timber. For each dugout canoe, two or three planked canoes can be built. The Bay of Bengal Programme (BOBP) undertook a project in Nias Island, Sumatera, Indonesia, and Shri Lanka to design and construct planked outrigger canoes that would provide an answer to the problems now being laced in building the traditional outrigger canoes.

    A Manual for Operating a Small-scale Recirculation Fresh water Prawn Hatchery - BOBP/MAG/13 1993

    in Potiya, near Chittagong, Bangladesh, is written for those interested is establishing a small-scale inland freshwater prawn hatchery using the clear water method. It is assumed that the reader has some basic knowledge of aquatic biology, but is not necessarily a degree holder in the subject. The method described is based on the use of brine obtained from salt pans. The brine is diluted with well or surface water to make up the rearing water. Such technology is widely used in commercial hatcher ies in Thailand. As rifle is not always available, a simple biofilter, for recirculation of the water, is incorporated in the tank design. The biofilter greatly reduces, or eliminates, the need for water changes during the rearing cycle. The hatchery system described consists of larvae rearing tanks, mixing and brine storage tanks, Artemia incubators and supporting mechanical equipment. Recirculation systems are becoming increasingly popular and have now been shown to give consistent product ion of quality post-larvae. All the necessary details for setting up such a simple system are included in this manual, which is also profusely illustrated to make what is described in the text clearer.
