There was no Irish Sea. Just for the most part an empty basin in the middle of which was a body of runoff<br />

water forming a large lake linked to the surrounding land and distant ice free sea by a number of<br />

rivers.<br />

This lake was post glacial Lough Hibernia, and in it lived members of a family of fishes known as the<br />

whitefishes, represented in the present day British Isles by Coregonus lavaretus, the English schelly,<br />

Welsh gwyniad and Scottish powan, which despite the name differences are all the same fish, and<br />

Coregonus albula, the English vendace and the Irish pollan. Then, as the ice lost its strangle hold and<br />

started to melt, sea levels began to rise, eventually creating the geography we see today.<br />

At some stage in that transition, the sea broke through the Kintyre land bridge isolating Ireland from<br />

Scotland, eventually filling up the Irish Sea.<br />

As it did, it obviously mixed with the waters of Lough Hibernia greatly increasing salinity levels there,<br />

either killing off its intolerant inhabitants, or as in the case of the whitefish species, sending them<br />

scurrying up the nearest rivers, initially populating many stretches and lakes, until ultimately when<br />

things became too warm for them, at most locations they died out, leaving just the handful of scattered<br />

remnant struggling populations we have today.<br />

Seven populations of Coregonus lavaretus are recorded as managing to hang on in the British Isles, all<br />

of them living in England, Scotland and Wales. None survived in Ireland, though the Irish have four of<br />

the seven recorded populations of Coregonus albula, which because there is no rod caught record for<br />

that species, ceases to be of interest to us here.<br />

Schelly are found in Ullswater, Haweswater, Brothers Water and Red Tarn in Cumbria, Llyen Tegid<br />

which is Bala Lake in Wales (gwyniad), and Lochs Lomond and Eck in Scotland (powan). However,<br />

when I first became interested in the species, Brothers Water was not an inclusion on that list.<br />
