Ian O'Leary, Corporate Communications Director at Seagate, refused to make a firm commitment at this stage on what anglers would consider a significant goodwill gesture from the company. Mr O'Leary also confirmed his understanding that no formal approach had yet been made by the local Association.
But he said anglers would be given a very good hearing from Seagate should the Association come forward with a reasonable proposal.
"We haven't heard from the Roe Valley Angling Association at this stage and to be honest I'm not entirely sure what exactly would be involved in the restocking - I'm not an expert.
"What I can say is that we would certainly listen very sympathetically to what they have to say," said Mr O'Leary.
He reiterated the assertion by a company solicitor at Limavady Magistrates' Court last Wednesday of the firm's "very good record on the environment."
Seagate was fined a total of £6,000 for discharging toxic chemicals into the Limavady sewerage system in 2005 on the same day that hundreds of sea trout and salmon died in a major fish kill on the River Roe.
Roe Valley Angling Association now says it is extremely concerned over the long term impact the 2005 fish kill could have on the Roe salmon and trout population.
Despite enjoying a bumper season last year, the four to five year migration cycle of salmon and trout means the full effect of the 2005 catastrophe will only be felt in the year's ahead, with less and less fish returning to the Roe to spawn over the next two seasons.
The Association is currently taking advice from solicitors, the Ulster Angling Federation and the Loughs Agency.
Restocking, it says, is not the only option available. Efforts could also be made to enhance habitat and nursery areas for juvenile fish in the future, the Association suggests.
Speaking on behalf of the Roe Valley Angling Association, Davy McCool, said: "As a courtesy thing, if Seagate were to restock the river, it would be appreciated. A restocking scheme would be something that could be done.
"But maybe something else could be looked at with the development of the spawning beds further up the river - just to get it back going again.
"In terms of conservation it would actually help the river's fish population get back on its feet. At the moment there may be plenty of salmon in the Roe, but with those salmon being killed four years ago and it being a four year, five year cycle, we could hit the wall and have nothing. It is that gap year coming up now that we are most worried about."
At Limavady Magistrates' Court last Wednesday Resident Magistrate Eamon King expressed surprise that no restocking or analysis costs were claimed by the prosecution saying: "Industrial processes have an obligation to examine that anything emanating from the plant is not harmful to local wildlife."
