How has Totnes weir pool fished?

Since fishing restarted last month, TWP has fished reasonably well, with a decent number of sea trout caught up to 5 or 6 pounds.

In May, about 400 fish passed through the fish counter, mainly sea trout. In June about 150 had been counted at the last check.

Of course the fishing in TWP will now tail off as the fish move upstream.

Oddly, given their prevalence over the past few years, no sea lice have been seen on fish and no fish with saprolegnia fungus infestations have been reported. Could this be some effect of lockdown or is it just coincidence?
