Something fishy ...

Blackweir is an ancient weir on the River Taff built in the 19th century to supply water to Cardiff docks. The weir blocked the migratory route for salmon and sea trout, which were already in decline due to pollution.

In the 1980s water quality in the Taff and other local rivers had improved as pollution control measures were introduced. As a result, sea trout and salmon started to re-appear in the river. The obstruction of Blackweir now became an issue so a fish pass was constructed to ensure that fish could progress upstream to spawn for the first time in over 100 years.

Today, there are plenty of salmon, sea trout and eels in both the Taff and the Ely rivers and salmon are spawning successfully in both.

Now, a larger and more effective fish pass is being built to ensure that all species of fish will be able to move freely past Blackweir and that the Taff will fully recover its fish stocks.

That all means something, but I’m not sure what.
