JOHOR BARU: A change in the ecosystem and surrounding areas may be the cause behind the recent occurrence of dead fish in the Lido beach area and a canal near Hospital Sultanah Aminah here.

State Local Government, Urban Wellbeing and Environment executive councillor, Tan Chen Choon (pix), said however that his team was waiting for a full report from the Department of Environment and the Department of Fisheries, before any action could be taken.
