The environmental watchdog Natural Resources Wales says the number of fish getting up-stream – from the sea through into Cardiff Bay and up the rivers Ely and Taff – is declining, according to the latest figures reported to the Cardiff Bay Advisory Committee.
Natural Resources Wales has told the committee that the numbers of fish going upstream from the sea via the barrage “fish-pass” are declining – but no one knows why.
The fish-pass itself did work quite effectively when Cardiff Bay was first impounded, with stocks of salmon and other species recovering as they made the challenging swim upstream though the fish pass into Cardiff Bay and up the two rivers .
Now the numbers of fish making the challenging upstream swim is in decline and a new investigation is being carried out to find out why there’s such a large fall in upstream fish migration.
The situation hasn’t been helped by a fractured pipe in the fish pass which has forced the temporary closure of the entire system. It still hasn’t been repaired .
Natural Resources Wales has also reported that some local anglers have been arrested for alleged “illegal fishing around the Penarth Sea Fishing Competition“.
Details of the numbers of anglers apprehended, and the offences which they’re alleged to have committed, have not been provided.
