Environmental Management Authority CEO Dr Joth Singh has ruled out poisoning in the death of hundreds of fish found in a section of the La Pastora River, Santa Cruz, on Friday.Singh said EMA's investigation showed the fish kill was caused by the silt in the water, because of the construction of a wall near the site. He said EMA investigators who went to the site found approximately 50 different species of dead fish.
"Based on our investigation, we connected it to a development occurring in the La Pastora area, by a contractor acting on behalf of the Drainage Division of the Ministry of Works," he said.He explained that the contractor was engaged in preparatory work to strengthen the river wall. He said the activity created a high turbidity level (of silt) in the water.
"We recognise a fair amount of silt was being generated by the operation (construction) itself that led to high turbidity levels in the water in the vicinity of the construction. We expect the fish kill was associated with the high levels of turbidity in the water...There was no episode of poisoning."What the contractor should have done was to block off the area to prevent any silt from entering the water column."
He said he did not think there would be any work stoppage, as a significant portion of the work has already been completed.However, the investigators have been liaising with the contractor to ensure that he takes precautionary measures to prevent a reoccurrence although a significant part of the work has already been done.
The EMA was alerted to the situation on Friday by one of the directors of the Papa Bois Conservation Marc de Verteuil. The matter was also reported to the Institute of Marine Affairs.
