Performance of marine fishing industry in Karnataka : An analysis using total factor productivity

Abstract

Karnataka is a prominent maritime state in the south-west coast contributing 10.7% of the marine fish landings in India. Total factor productivity of marine fish production in Karnataka State for the period 2000 to 2010 was analysed using Divisia-Tornqvist indexing method. Quantities and revenue shares of 18 marine fish resource groups were taken for developing the output index and quantities and cost shares of fuel, labour and fixed capital were taken for developing the input index. Most of the marine fish resources including oilsardine, catfishes, lizard fishes, mackerel and cephalopods showed positive growth in landings during the study period. The output index, input index and total factor productivity growth were 6.2, 2.9 and 3.2 respectively and 51.69% of the output index growth was contributed by total factor productivity growth. This indicated the economic sustainability of marine fish production in the state in the short run period.
