The announcement came shortly after mass fish deaths in Taungthaman Lake, Amarapura Township, in April were blamed on pollution from sewage.
In addition to the freshwater fishery law, violators would face legal action from other departments. Factories, workshops, traders and restaurants near the lake need to follow the law, rules, regulations, procedures and directives to avoid causing environmental damage, the department said.
Officials will add fish to Taungthaman Lake, one of Mandalay’s highlights, in an attempt to replace numbers.
