Fisheries investigators found dead fish over a 5km stretch of the river in the Tolka Valley Park area, following the report on Tuesday 18 September.
According to IFI, a “significant source of polluting material has been identified” and samples were taken for analysis.
In the meantime “relevant parties are undertaking appropriate remedial action” as the investigation continues.
IFI will begin operations in 2019 to remove the aquatic plant Lagarosiphon major from the lough, after successful cutting and picking operations over the summer months this year.
In addition to these management operations, IFI commenced a research project last month which aims to establish the current distribution of L major in Lough Corrib.
New innovative methods are being trialled to survey the aquatic plant as part of this research. These include unmanned aerial drones, sub-aquatic remotely operated vehicles (ROVs) and modern remote sensing techniques.
Speaking as he visited IFI’s stand at the National Ploughing Championships, Minister Kyne also asked the fisheries body and his department to continue liaison with the National Parks and Wildlife Service (NPWS), who have responsibility for the legislation covering Alien Invasive Species (AIS).
According to TheJournal.ie, as many as 500 fish were killed over a 3km stretch of the waterway between Mulhuddart and Blanchardstown after the blockage caused a manhole cover to overflow into the river.
Since then, local angling shop proprietor Derek Talbot has described it as an “absolute disaster” for West Dublin’s angling community.
The Tolka previously suffered an extensive fish kill almost exactly three years ago, affecting thousands of fish downstream from Finglas Road in Glasnevin.
#fishkill – Inland Fisheries Ireland and Dublin City Council are today (23.07.14) continuing to monitor the River Tolka following a significant pollution incident which occurred yesterday, Tuesday 22nd July.
A definite line of inquiry is being followed in relation to the source of the pollution incident which resulted in an extensive fish kill in the river.
Further samples have been taken and analysis is ongoing.
Dublin City Council has also removed a boom wall barrier which it erected across the River Tolka at Griffith Park yesterday to contain the pollutant as this is no longer required.
Inland Fisheries Ireland (IFI) has a confidential hotline number to enable members of the general public to report incidents - 1890 34 74 24 or 1890 FISH 24. This phone line is designed to encourage the reporting of incidents of illegal fishing, water pollution and invasive species.
#fishkill – Inland Fisheries Ireland and Dublin City Council are today (22.07.14) investigating an extensive fish kill on the River Tolka in Dublin City.
The latest indications are that the fish kill extends from an area in the vicinity of Finglas Road Bridge for a considerable distance downstream. The full extent of the kill has yet to be quantified.
Inland Fisheries Ireland and Dublin City Council are continuing their emergency response and associated investigations in an effort to establish the source of any contaminating material that may have caused this major pollution event.

Atlantic salmon have joined four other native fish on a 'red list' of endangered species compiled by the Ireland's fisheries and wildlife agencies.
As the Irish Independent reports, one third of the State's 15 native fish species are considered endangered or vulnerable.
One of the worst hit is the European eel, which was found to be critically endangered.
In a report published yesterday, a number of threats were highlighted such as water pollution, invasive species, overfishing, poor river management and climate change.
According to The Irish Times, the Red List was compiled by scientists from organisations across the island including Inland Fisheries Ireland, the National Parks and Wildlife Service, the Northern Ireland Environment Agency and the National Biodiversity Data Centre.
The news comes just a few days after Dublin celebrated the return of wild Atlantic salmon to the River Tolka after more than a century.

Dublin has yet another thing to celebrate with the news that wild Atlantic salmon have returned to what was long regarded as the dirtiest of the capital's inland waterways.
The Irish Independent reports that the fish have been spotted along the banks of the Tolka between Glasnevin and Finglas for the first time in at least 100 years.
Efforts to clean the river in recent years, as well as the removal of man-made weirs, are thought to have aided the recovery of the Tolka, which now provides plentiful nutrients for migratory fish.
Atlantic salmon in particular are considered by scientists to be a 'bio-indicator' in that they require a very high standard of water, so their presence in a given area defines it as a healthy environment.
The Tolka joins the Liffey and the Dodder in the list of Dublin rivers hosting thriving stocks of young fry in what has been a bumper year for salmon angling across the country.
