Tyne Angler Scale Sampling Programme. October 2011

Editor

The Salmon Atlas
The upstream count for October 2011 was 8,777 and is seventh highest in our records; the highest (14,066) was recorded in 2003. The 2011 count was 178 higher than the 5 year average (8,599) but 151 lower the 15 year average (8,928). The upstream count for 2011 up to the end of October was 32,660 which is the fifth highest total for this period ; the highest (44,761) was recorded in 2010. The highest daily counts were recorded on 4th, 14th and 23rd October, with 559, 527 and 597 being recorded respectively. The upstream count for November up to approximately 09:00 on the 4th was 1042.

The majority of the upstream counts were recorded between 8am and 4pm, while fewest counts were recorded between 6pm to 5am. The timing of when upstream counts were being recorded in 2011 is similar to what has been observed in previous Octobers with the exception of 2009 where counts were recorded equally throughout the day. Although, the 2011 footage is yet to be reviewed, short viewings whilst visiting our facility at Riding Mill suggest that the number of sea trout observed will be greater than the number of salmon observed.

Further details of the daily upstream counts for 2011 and historic monthly counts can be found by following the link below:

Environment Agency - River Tyne fish counts



The chart above shows that counts were recorded in three distinct groups 1st to 8th, 14th to 17th and 22nd to 31st. The first two groups were separated by a spate on the 9th with counts only recovering once levels had receded sufficiently on the 14th. The second and third groups appear to be separated by a period when river temperatures dropped along with modest rises in river level. Counts only recovered in third period after river temperatures started to increase. Generally there is little association between levels and counts recorded except that beyond a certain level passage is inhibited, however, changes in the temperatures appear to show a positive association with changes in counts; generally, as temperatures increase so do counts whilst declining temperatures show the opposite.

If you are not already aware, we have a system on the internet that will allow you to check river levels before you head out. Please follow the link below:

Angler Scale Sampling Programme 2011

We have received 58 scale samples during October 2011, 44 coming from salmon and 14 from sea trout, bringing the total for the year to 442. If you are waiting for the results from samples, I am hoping to have all samples read and certificates sent out within the next fortnight. All scales that have been sent in are recorded onto a database and referenced to prevent them being lost or misplaced. Please accept my apologies for the delay in getting this information back to you.

The Angler Scale Sampling Programme is part of the impact assessment into the construction of the Second Tyne Tunnel. Support of the Angler Scale Sampling Programme and Angler Logbook Scheme will ensure that these monthly updates will continue. Please remember we want samples from fish of all sizes not just the very small and the very large.

If you require more scale packets please drop me an email.

Many thanks for you support
