Unusual arrival of dace

I AM researching a project about Irish freshwater fish species. The other day I set off in search of dace. The dace has an interesting story in this country which is quoted in all the scientific papers and popular articles about them.

In 1889 a party of English pike anglers arrived in Ireland and they brought their own live baits with them. At the end of their trip they tipped their surplus baits into the River Blackwater thus introducing two new species to the country — the roach and the dace.

I’ve searched hard but I can’t find the original reference on which this story is based or any more detail about it. For instance I don’t know where the incident happened — and the Munster Blackwater is a long river. I do have my suspicions though.
