Economics of trawling along Goa coast

A trawler on an average earned a gross revenue of Rs. 6,28,800 during 1991-'92. The annual cost of trawl operation is calculated at Rs. 6,03,705. Thus, an amount of Rs. 25,095 is found to be the net profit of a trawl unit. The income over operating expenses comes to Rs. 1.82 lakh. By investing one rupee on fuel, an amount of Rs. 2.52 is earned by a trawler. It requires 6 years to recover initial investment in a trawl unit with the average production of 43,520 kg of fish per annum with a price of Rs. 14.45 per kg. The rate of return to capital is calculated at 20% which is higher by 5% than the rate of interest on which capital was made available for acquiring the trawlers
