Something fishy going on
There was outcry 25 years ago after invader fish hit Loch Lomond.
Local fishermen, biologists and scientists hit out after the loch and its tributary rivers, the Fruin, Endrick and Leven suffered a dramatic change in the fish community.
This was due to the introduction of five new species of fish brought up from the south of England.
Fishermen after pike used these fish as live bait before dumping the excess live bait into the loch at the end of the day.The issue was so severe that a new by-law advisory committee considered legislation to ban the dumping of unwanted live bait.
Colin Adams, of the University Field Station at Sallochy, a representative for the Loch Lomond Research Group, said there were a number of concerns, including over one species, the dace.
He said:“The main worry about the dace is that it is taking over some areas of the River Endrick where salmon and brown trout are normally found.”
Experts said the problem would continue unless something was done soon.
