    Aluminium alloy as sheathing material for the wooden hulls of fishing boats
    (1965) Balasubramanyan, R.
    Trials with indigenous aluminium-magnesium alloy as a substitute for copper in sheathing wooden hulls of mechanized fishing boats have given promising results. Costing only a little over one third as copper, the alloy sheathing has been giving satisfactory service for over 18 months since the boat was commissioned for regular seafishing operations off Cochin.

    A case history on the phenomenal corrosion of marine propellers in fishing boats
    (Society of Fisheries Technologists (India) Cochin, 1973) Balasubramanyan, R.
    Although high tensile brassess of copper-zinc alloys (Manganese bronze) find extensive use in all marine applications, under aggressive sea-water, marine propellers cast out of such an alloy frequently suffer heavy corrosion damages due to dezincification . An interesting case history where a number of propellers have undergone dezincification in the Cochin back-waters is narrated in this paper .

    Cathodic protection of aluminium sheathed wooden fishing boats with ternary aluminium anodes
    (Society of Fisheries Technologists (India) Cochin, 1980) Pillai, A.G.B.; Ravindran, K.; Balasubramanyan, R.
    Results of laboratory and field trials on cathodic protection of aluminium sheathing in fishing boats by ternary aluminium anodes are presented . The high negative potential of 1 .06 V with respect to saturated calomel electrode, its appreciably low anodic polarisation and high current output are favourable factors for using the ternary aluminium anodes . The low rate of consumption of the anode material under service trials attests its economic viability .

    Experiments with fibreglass sheathing as a protection against marine wood boring organisms
    (1971) Balasubramanyan, R.
    Wooden test panels of different species of wood sheathed with fibre-glass reinforced plastic were subjected to immersion tests along with corresponding controls in Cochin Port area and the effect of the protective coating studied.

    Further account of the rocklobster fishing experiments with bottom set gill nets
    (ICAR, 1961) Balasubramanyan, R.; Satyanarayana, A.V.V.; Sadanandan, K.A.
    this paper is made an attempt to know the fishing experiments in the bottom ste gill nets areas of kollam,vizhingam,varkalla and colachal-muttom. also this paper shows the experimental rock-lobster fishing operations conducted during the 1958-59.

    Gel time studies in the activation of polyester resins
    (1971) Balasubramanyan, R.
    Gelling times of polyester resins with varying quantities of catalyst and accelerator were studied and the results reported in this communication

    Indigenous substitutes for imported natural resin, 'dammar batu'
    (1967) Balasubramanyan, R.
    Use of indigenous resins in place of imported ‘dammar batu’ for surface coating of fishing boats has been suggested. The indigenous resins are not only equally good, but cheaper also.

    Spiny lobsters and their fishing techniques
    (1981) Mohan Rajan, K.V.; Meenakumari, B.; Balasubramanyan, R.
    Scores of publications on spiny lobsters and their :fishing techniques are available from various parts of the world. A variety of fishing gears which vary in design and operation are employed for exploiting lobsters. A review of the work carried out on spiny lobsters with special reference to their distribution, fishing gear, fishing methods, baits and crafts in India, Sri Lanka, United States, Australia, South Africa, United Kingdom, Ireland and Portugal based on selected literature are considered and discussed.

    Studies on arsenical creosote as wood preservative for marine structure II - Observations on leaching, corrosion and resistance to borer attack
    (Society of Fisheries Technologis(India), 1972) Unnikrishnan Nair, N.; GopalakrishnaPillai, A. G.; Balasubramanyan, R.
    A detailed study on arsenical creosote with reference to leaching, corrosion and anti-borer properties was carried out. Results showed that aging had very little effect on the preservative which suggested better fixation of the preservative into the wood. Corrosion of mild steel, galvanised iron, aluminium-magnesium alloy (M57S) and copper panels in the preservative was found to be negligible, Normal creosote and low temperature creosote of Regional Research Laboratory, Hyderabad, both fortified with arsenic trioxide resisted borer damage on wooden panels for a period of over five months in the port of Cochin. The performance of low temperature creosote fortified with arsenic was found to be equally satisfactory when compared to normal creosote fortified in the same manner A loading of 208.6 Kgs/m3 for Haldu (Adina cordifolia) and 138 Kgs/m3 for Mango (Mangifera indica) in the case of normal creosote and 177 Kgs/m3 for Mango in the case of RRL creosote were found to be sufficient for treating the wood.
