    Conversion of mechanised fishing vessels to tuna longliners
    (Society of Fisheries Technologists (India), 2010) Baiju, M.V.; Thomas, K.; Rajeev, G.D.; Raj, J.E.P.; SaIim, P.M.
    Exploitation of tuna resources has been identified as one of the thrust areas for increasing export of Indian marine products (Joseph et al., 2008). The Indian EEZ alone has a resource potential of 0.21 million tonnes of oceanic tuna consisting of yellowfin 54%, skipjack 40% and bigeye 6% (Anon, 2000). The resources extend tar beyond the EEZ as tunas are highly migratory and straddling stocks. Tunas are exploited by a variety of gears and major share in India is landed by gill nets, followed by hooks and lines and purse seines (Pravin, 2009; John and Pillai, 2009). Tuna landings along he Indian coast was estimated at 61,972 t during 2009, and the fishery is supported mainly by Euthynnus affinis, Thunnus albacares, Auxis spp., Katsuwonus pelamis, Thunnus tonggol (CMFRI, 2010). Stock assessment has indicated that while nearly 86% of the coastal tuna potential is being exploited, only less than 15% of oceanic tuna potential is currently being exploited (CMFRI, 2010). Tuna resources in the shelf are more or less fully utilized and that further avenue for development lies in harvesting the oceanic tuna stocks. Fishing capacity from the shelf fishery is being diverted, with appropriate modifications, for harvesting the oceanic tuna resources.

    Design, construction and prototype testing of FRP boats for reservoir fishing
    (Society of Fisheries Technologists (India), 2001) Baiju, M.V.; Meenakumari, B.
    Scarcity of the traditional boat building material viz, wood forces the designer to find an alternate material for the construction of fishing boats. Fiberglass Reinforced Plastic (FRP) is emerging as a suitable material in this field, especially for small crafts and reservoir boats. The design of a 4.57 m L A FRP boat was prepared at the Central Institute of Fisheries Technology for gillnet fishing operations in reservoirs. This boat was designed with three seat-cum-buoyancy tanks and a forward chamber. Two rings in the aft and a towing hook in the forward were provided for pulling the boat to the shore. A pair of oar locks were also fitted for rowing the boat. The aft is designed to fit a 15 hp outboard motor. Two numbers of this boat were designed and constructed and the weight of each boat is 220 kg. The hull laminate consists of one layer of CSM300, three layers of CSM450 and one layer of WR 610. The outside hull is applied with a gel coat and colour pigment for getting finer finish. The frames are made of two layers of CSM450 and the frame spacing is 380 mm. The boats powered with 15 hp outboard motors. were tested for performance in the Hirakud reservoir (Burla. Orissa). The boats were found to be watertight, stable, strong and convenient for fishing in reservoirs.
