I am going through a number of documents and papers on global and country-wise hilsa catch. As I can see 60-70% global hilsa catch come from Bangladesh. Having said that, different documents give different percentages. The countries like India, Myanmar, Thailand, Pakistan, Iran and a few others are also considered as hilsa nations. Is it possible to prepare a country-wise and year-wise hilsa catch data for all the hilsa nations, agreed by the scientists and supported by the authentic national data sources - that is non-existent at the moment.
