Sampling methodology employed by CMFRI for monitoringudthe fishery and estimation of marine fish landings in India

摘要

Fisheries sector plays a key role in Indian economy. The sector supports livelihood, nutritionaludsecurity, and subsistence to large number of people as well as foreign exchange earnings.udIndia’s coast line stretches about 8129 km. There are 1355 landing centres scattered alongudthe coastline of the main land as per the records from National Marine Fisheries Data Centreudat Central Marine Fisheries Research Institute (CMFRI). Marine fish landings take placeudalmost all along the coast line throughout the day and sometimes during night. Underudthese circumstances, collection of statistics by complete enumeration would involve a veryudlarge number of enumerators and a huge amount of money apart from the time involvedudin collection of data. Therefore, a possible solution for quantifying marine fish landings isudadoption of a suitable sampling technique. As, monitoring and assessment of the exploitedudmarine fishery resources of India is one of the important mandates of the CMFRI, instituteudmade attempts to evolve the scientific methods for collection of data on catch and effort,udsince its inception in 1947. Pilot surveys were conducted along the coastline of India anduddifferent sampling designs were tested.
