Readers of the blog and followers of the Spey will be aware that the Tommore Burn has been stocked with 0+ salmon for a number of years and since 2013 all stocked fish have been fin-clipped. We surveyed two of the regular monitoring sites in July one very still and midge infested evening along with some of the Spey ghilies. The remaining two sites we left until the last day of the 2015 electrofishing programme, mainly so that we would be able to assess how well the 2015 stocked fish had done.
The four electrofishing sites cover the lower, middle and upper reaches of the burn, straddling a range of habitat zones from mixed broadleaf to moorland fringe in the upper site.
The results from the 2015 monitoring with 2014 for comparision, are shown below.
Although we are only dealing with two sites and small numbers of fish it was interesting to note that the mean size of the stocked fry in the lower site was 55.4mm whereas it was 58.5mm in the upper site.
We are building up a good set of data from the Tommore Burn now; electrofishing and smolt trapping, both of which we will continue in future years.
