This matter has been a bone of contention for years. The fish pas was

Is there a counter on the river?

Cheerio,

Don't think so - it was the failure to accurately monitor fish migration
that cocked up the study. The study took place after the fish-pass cills
where modified to make the torrent less violent.

Nogood Boyo will have the answer if he reads this.

As far as I am aware here is no fish counter, fish were trapped or seine
netted and tagged with combined acoustic and radio tags then tracked by a
combination of sonar bouys and radio trackers.
