    Marine fish production from capture fisheries in India has increased by about six fold during the past six decades. Export earnings from the marine sector crossed 12,000 crores in 2010-11 and gross revenue through marine fish landings at the point of first sales was about 20,000 crores. Marine products are now exported from India to nearly 100 countries. Monitoring the harvest of different marine fishery resources is very much essential for planning and implementing policies for sustained production from the sea. The dynamic changes in the landings of marine fishery resources over the last six decades were examined after classifying them into 26 different resource groups. Decadal averages of landings of different resource groups were compared using Student’s t test and coefficient of variation was worked out for each decade. Present status of each resource group was examined separately based on a simple criterion. Out of the 26 groups examined, 18 were found to be under the ‘abundant class, 5 under ‘less abundant’ class and one each under ‘declining’, ‘depleted’ and ‘collapsed’ classes. Elasmobranchs, threadfins, ribbonfishes, mullets and flatfishes are the five resource groups falling under ‘less abundant’ class. White fish falls under ‘declining’ class, flying fishes under ‘depleted’ class and unicorn cod under ‘collapsed’ class. All the other groups fall under the ‘abundant’ class indicating that most of the resources (73%) are in healthy condition. The ‘depleted’ and ‘collapsed’ classes require management interventions for the recovery of the resources and the group falling under ‘declining’ class needs caution and care to prevent further reduction in the stock.
