The 22-day ban on catching, selling, hoarding and transporting of hilsa—starting October 14 -- aims to protect the safe spawning of the fish during its peak breeding period.
A team of river police led by Fairda Parvin, additional SP (media) of River Police, started a drive against hilsha catching from Dhaka on Saturday.
After conducting a drive in Shariatpur, they came to Rajrajeshwar union in Chandpur around 10am, said the additional SP.
When they came to the Shilarchar, they saw that around 3,000-4,000 fishermen were catching hilsha defying the government ban, she added.
Later, the team members seized several boats and nets from the spot.
When the news spread among the other fishermen, they attacked the team with brick chips and sticks.
