People will get more delicious hilsa on their plates this year thanks to drop in river pollution due to suspension of river transport movement for several months due to coronavirus pandemic, says an expert.       Dr Anisur Rahman, a renowned hilsa expert at Fisheries Research Institute, Chandpur, came up with the information while talking to UNB.   “We have examined  the river water and found that the pollution level in the river has reduced due to the suspension of river vessel movement amid the Covid-19 pandemic. The condition of the river was quite congenial to availability of fish food. So,  this year's hilsa will be more delicious, more flavorful,” he added.   Hilsa has become available now in local markets due to the rise in river water level and rain while though August, September and October months are the peak time to jave hilsa, he said.
