JOHOR BAHRU: The Johor Fisheries Department has suggested treating the seawater at Pantai Lido as an immediate measure to prevent further mass fish deaths in the area.

The department’s director, Zamani Omar, said a water analysis report on Aug 28 showed high ammonia and phosphate content in the water, but this could be due to the decomposition of the dead fish.

“The situation will be worse if domestic wastewater also flows into the pond and threatens other aquatic life,” he said in a statement today.

For the long term, he said more efficient irrigation routes should be constructed to facilitate the flow of water in and out according to the tide.

This will prevent domestic waste from accumulating at one place and affecting the quality of the water for aquatic life, he added.

Mass fish deaths were reported on Aug 28 and Sept 6 at Pantai Lido and an irrigation canal near the Sultanah Aminah Hospital.
