1. What has been the average annual fish landing in India state-wise for the last 1.5 decades … say from the year 2000? In 9 maritime states and 2 UTs: On an average for India we are producing nearly 3.5 million metric tonnes.
2. Do you see a change in fish landing in these years? We do see changes in marine fish landing pattern. This change is observed since we started collecting the data and inferred based on the historical time series. It is termed as inter annual fluctuation in fish landing. Our Institute ICAR-CMFRI was established in 1947. Within a decade we standardised the procedure for collecting fish landing data from all nine mainland maritime states and two UTs (Daman and Diu and Puducherry). The methodology developed is vetted by the FAO of the UN. If we look into the fish landing data, since 1950s onwards we can see this inter-annual fluctuation occurring in marine fisheries. This is a natural phenomenon … some species increase and some others may decrease. On an average there is an increasing trend since 1950.
3. To what do you attribute the decreasing fish landing year wise in the past few years? Not true. The decrease in fish landing is only relevant data after 2012 for a short period of three years recently. During 2013, 2014 and 2015 there was a decreasing trend in national landing data, but again in 2016 there is a slight recovery. Despite El Nino, during 2015 fish landing data at national level was 3.4 million metric tonnes. In 2012 when the maximum production was reported we produced 3.94 MMT.
4. How did El Nino of 2015 affect fisheries in South Asia? Please give me detailed data state-wise for India, country wise for SAARC countries and a generic perspective on the Indian Ocean fisheries. If we see the data for 2016 it’s a 6.6% increase compared to 2015. The fall in landing in 2015 was mainly because of the decrease in landing of Indian Oil Sardines a pelagic fish species dominant in Indian marine fisheries. We don’t have data for SAARC countries country wise.
5. Why has fish landing in Gujarat increased while that in Kerala has receded to the 4th place in the last 5 years? Is the delta ecosystem of the Indus a factor in increasing fish yield on the coasts of Gujarat? Or could it be that fish are migrating north to escape the warmer seas near the equator? Gujarat tends to be a dominant fish catching state in India always. But during some years Kerala got the top slot because of bumper catch of Indian Oil Sardines which is the dominant fishery in Kerala waters. Gujarat fishers led on account of catch of demersal species such as Croakers and Sciaenid.
