Tweed BioBlog: week beginning Monday 5th September 2016

Monday: Main event today entering the data from the Fry Index electric-fishing of the Ettrick. Normal to good results for most of the river, especially for the Tima & Rankle, the upper tributaries which had some of their best fry numbers ever, but very poor at the bottom, downstream of the Philiphaugh cauld.  Netting at Paxton in the evening – very poor, only one Sea-trout. Tuesday: electric-fishing the sites on the middle Yarrow, downstream for the lochs. Average numbers, but the Yarrow always has lower fry numbers than the Ettrick, being chemically poorer and so less productive. Wednesday: in the office all day, then down to Paxton again in the evening for another very poor session, only a Sea-trout and a very fat Brown-trout. The water very warm and a slight smell as the tide pushed upstream. Thursday: electric-fishing on the lower Yarrow, just a few sites to finish off, and just normal results for that zone. I wasn’t at the nets in the evening, but a better catch, four Grilse, a Salmon and a couple of Sea-trout. Friday: more admin and office clear-out.
