    Classification of fishing boats
    (Central Institute of Fisheries Technology, 2000) Edwin, L.
    The term "fishery vessel" comprises mobile floating objects of any kind and size operating in fresh water, brackish water and marine areas and used for catching, transporting, landing, preserving and/or processing of fish, shell fish and other aquatic vessels performing other functions related to fisheries such as supplying, protecting, rendering assistance or conducting research or training. The term "Fishing vessel" is used to distinguish fishing vessels engaged in catching operations. The remaining fishery vessels are covered by the term "non fishing vessels".

    Fishing craft materials
    (Central Institute of Fisheries Technology, 2002) Edwin, L.
    Newer materials like fibreglass, ferrocement and aluminium are coming up as suitable substitutes for wood as this conventional material has started becoming scarce and therefore very costly. As regards service life under critical conditions the new materials show promise, however wood and steel permit greater versatility due to their well-known characteristics and working qualities which are discussed in this paper.

    Wood preservation
    (Central Institute of Fisheries Technology, 2000) Edwin, L.
    Timber in various forms is subjected to biodeterioration. Traditional crafts are mostly affected by wood rotting fungi; and mechanised boats by marine wood boring and fouling organisms. Fishermen resort to various types of indigenous preparations, majority of which are found not giving proper protection as established by CIFT's investigations. Chemical wood preservatives with toxic ingredients, when properly treated can give adequate protection to wooden structures against decaying organisms.
