RIVER TYNE (EAST LOTHIAN ANGLING ASSOCIATION)
This sponsored Advisory visit was undertaken by Ron Holloway (RH Associates) on behalf of the Wild Trout Trust in the company of Hugh Dignon (Organiser of visit). David Elder (Secretary ELAA) and officers and members of the Association, Archie Richmond, David Connell, John Proctor, Tony Hawkins and Brian Davidson (Member) but attending on behalf of the Association of Salmon Fisheries Boards (ASFB).
OBJECTIVE OF ADVISORY VISIT
To identify any limiting factors that may be controlling the survival of the resident population of wild brown trout and to suggest any actions that can or should be taken to protect, maintain, enhance or restore habit for the welfare of self sustaining species of salmonids both resident and migratory. To suggest a outline framework for establishing a ongoing integrated management plan for the Association to work from in the future. To assist in the formulation of a management plan which will also be used as essential evidence to demonstrate the objectives of the Association in their negotiations for longer-term leases with riparian owners. This plan is required to ensure the vital security of tenure of the waters now under the Associations present control. Not until these longer-term leases have been negotiated should any major investments be made in implementing any long-term plans. i.e. Aim for an absolute minimum of five year leases with 10 year or more if and where negotiable. Legal advice in the drawing up of all leases is recommended to be taken to safeguard against any future problems that may arise with owners particularly where land ownership changes hands.

SAMUELSTON FARM
At this site the riverbanks have been heavily grazed and the river channel affords little adult fish holding cover.
To address these problems
firstly plant a selection of natural imported rock clusters in a random
placement within the middle third of the river channel. These clusters will give added holding cover
for fish and aid a certain amount of scouring to deepen the areas around each
set of rocks to form more holding cover.
For ease of handling a good guide of size is a “two man rock” which
takes two men to lift and handle with ease.
It is stressed to place these rocks within the middle third of the
channel, this will prevent any bank erosion if rocks are placed near to the
riverbanks. Place rocks to be just (1”) out of the water at mean base flow levels.
The heavily grazed banks
should be planted up with willow saplings at intervals of 10 yards approx. The banks being fenced off from grazing
animals ideally should protect these plantings. Where fencing is done, access for animals to drink is essential
and the siting of access points should be discussed with the farmer.
The feeder stream and the mainstem along this stretch is drastically short of in stream holding cover so a series of random placed rock clusters should be placed within the middle third of the river channel. The riverbanks are also almost bereft of vegetation through over grazing so these banks should be fenced off. There is good holding areas within the deeper waters within the back up area upstream of the weir.
This stretch is in excellent order and it exhibits the entire right habitat and balances of cover for wild fish so nothing but protection is required here. Healthy river weed affords excellent cover for trout and habitat for aquatic insects. Tree density is about right.
This stretch appears to hold more sea trout than brown trout but there is no obvious reason for this other than the browns have been hammered by over fishing.
In my opinion all of the
weirs looked at during my visit had
fish passes (of sorts!) within them which
allowed migratory fish to pass over them only when water levels were high. I believe that these weirs between them do severely restrict any
regular upstream movement of fish at medium and at summer mean base flow levels. This in itself will cause the migratory fish to either congregate
below these weirs in low flows or return to the sea.

Congregations of fish below these weirs will only encourage the
poachers to predate on these captive fish!
Properly designed, sited and
constructed fish passes are very expensive to install. However serious consideration should be
given to obtaining the right advice on fish pass siting and planning and
construction that also includes costing.
It is understood that a new
fish ladder was installed on the Tyne during 2002. See Forth Fisheries
Foundation Annual Report 2002/2003. It is suggested that the Association
contacts Dr Colin Bull the Executive Director and Biologist for the Trust and
discus with him what action can be taken regarding any future fish pass
construction on the Tyne catchment.
RECOMMENDATIONS &CONCLUSIONS
The river Tyne in East Lothian is a naturally improving system that is recovering from the detrimental effects of many years of heavy industry and coal mining within its catchment. The general water quality throughout the system is good and samplings indicate A1 to B2 quality. This is underlined by recent invertebrate sampling that show an acceptable but improving diversity of insect species. Fish samples indicate improving wild brown trout survival from spawning in the headwater areas.
The priorities of the East
Lothian Angling Association has to be initially, to produce a well thought out
five, or more preferably ten year
management plan that will address all the problem areas discussed above. Before any major investment in time or
money is made to commence the implementation of any part of this plan, full
security of tenure of all the waters has to be negotiated with all the riparian
owners who lease waters to the Association.
A planned course of action for the years to come will give the
Association power to its elbow in its initial negotiations with the riparian
owners. This action plan will show to the land owners clearly that the Associations intentions to protect, maintain and
improve the habitats and waters of the river Tyne will also be of benefit to
them as it will improve the value of their property. In order to impart more impetus (clout!) into the content of the
management plan it is recommended that the ELAA discusses and takes further
advice on the content with all of the following organisations. The Forth Fisheries Foundation, The Forth
Salmon Fisheries Board, SEPA, SNH, The Wild trout Trust and FWAG. To have the plan endorsed by all these
groups will show to your landowners that the plan is sound and has the support
of all these well-respected organisations.
This in turn will surely help the Association to negotiate suitable
long-term leases. Furthermore it is strongly suggested that the Association
should invite all these groups around a table at the same time to agree and
discuss the action plan and this may
also be an opportunity to get some financial backing from each
organisation. In this regard I am
confident that the WTT (Wild Trout Trust) would look very favourably towards
“seed corn” funding the action plans that may trigger financial responses from
the other groups.
To give some guidance as to
the content of an action plan the following subjects can be considered. These
points are not necessarily in order of priority.
1.
Attain
long term security of tenure.
2.
Identify
all riverbanks that are open and
heavily grazed, with a view to fencing off. Discuss and take advice
on fencing and replanting of indigenous riparian vegetation from the Farming and Wildlife Advisory Group
(FWAG). The river is lowland in character and the intensive agricultural land
uses within the catchment do create the discharge of high levels of nutrients
in the form of phosphorus and nitrogen.
Therefore buffer zones between the waters edge and the ploughed crop
fields are required to mitigate the effects of the run off of all these toxic
nutrients. These nutrients are the cause of filamentous algae blooms in the
river at low water times in hot weather.
3.
Identify
all spawning burns and instigate an annual program of monitoring these burns for
debris dam removal to improve and maintain access by spawning fish.
4.
Identify
river reaches that are over shaded and
develop a program of tree thinning to achieve a 60:40 open and shade.
5.
Investigate
the potential for improving the efficiency of all the fish passes on all the
weirs.
6.
Identify
all the river channels that require adult fish cover enhancement with random
placed rocks.
7.
Discuss
the plans with the Forth Foundation and Salmon Fishery Board. et al
8.
Discuss
plans with the area biologist from SEPA
9.
Develop
and draw up a planning map of all the waters leased by the Association and
identify and mark all the problem areas and prioritise designated work action
areas. i.e. Weirs, overshaded areas, fencing areas, planting areas, instream
cover enhancement, etc etc From this a manageable annual work program can be
established. Remember to do a little
work well rather than a lot poorly!!!
10.
Maintain
records of all work undertaken so mistakes are not repeated!
11.
Make
catch records a priority and develop methods of encouraging members to complete
accurate catch returns.
12.
Consideration
could be given to reducing stocking i.e reduce catchables to about 500 but
include 4000 yearlings (3-4 inch) to see if they adapt to the system and grow
on. Either clipping off the adipose fin or panjetted with a readily observed
colour spot should mark these yearlings. This will give a good indication of
the survival from stocking through to catchable size. Accurate catch records are required and are most essential to
monitor this exercise. These fish to be seeded out in the upper regions of the
system where little fishing is done. As these fish grow they will tend to
migrate to the lower regions of the river. It is also suggested again that the
stocking of the catchables be done in the higher regions of the system for
the reason of reducing the over
exploitation just after stocking. Also
keep the stocking dates and sites
“confidential”!!
13.
Monitoring
of the potential spawning burns at the back end of the year to identify active
spawning areas which may need enhancement or further protection.
14.
Identify
avenues of funding that may be available for assisting in any expensive
work.
15.
It
is essential to establish and maintain a good rapport with all the riparian
owners and keep them informed regularly (twice a year at least) by a newsletter
on all work planned, or completed and or progress report on work in hand, be
the work on their land or not! Once the
Association can show clearly what its objectives are and what in fact it can
and is doing to improve things and is businesslike in its operations then
offers of assistance both practical and monetary may/will come from some very
surprising sources.
16.
To
raise local awareness and encourage good community co-operation and involvement
then invite all the Hotels and B&B’s locally to support the Association and
for the Association in return to promote the use of the local hotels and B&B’s by local and
visiting anglers via e.g adverts in the Association brochure.
17.
Arrange
for regular surveys to be undertaken that monitor invert populations and
diversity. Have surveys done to
monitor any changes in fish densities.
It is essential to measure the effects of all the work that is
done. Discuss this with SEPA and the
Fisheries Board/Foundation.
18.
Review
and possible revise upwards the fishing charges to a more economical level.
19.
As
and when the fishery improves then poaching will increase in proportion if
policing is not strengthened. It’s the nature of the beast! Discuss with your advisors from the Fishery
Board and the Foundation ways and means to improve the policing of the
fishery. Easy to say but difficult to
implement but the problem has to be addressed.! Experience has taught me that one good well reported
prosecution of a known poacher will usually get the word about the poaching
fraternity that it is getting too risky to poach the Tyne! Poaching will never
be eradicated completely but good policing will reduce the illegal fishing to
more tolerable levels.
It must be remembered that all the recommendations made in this report are focused on the wild brown trout habitats and management. What ever the nature of any work suggested or undertaken in the future it will also be of equal benefit to the sea trout and Atlantic salmon populations of the river Tyne.
In my opinion the River Tyne has great potential to become a self sustaining wild brown trout fishery although some form of stocking may be required in the short term if larger brown trout are expected to feature in catch returns. As the conditions and access for fish improves aided by the Associations work then the sea trout population will further improve as will the salmon. Consideration must therefore be given to planning for the future allocation (marketing?) of the sea trout and salmon fishing in the years to come. Wherever negotiations are made to acquire longer leases on waters some gentle, discrete and diplomatic enquiries can be made to ascertain who owns the salmon rights on each stretch and whether the renewed lease could also include the salmon rights. This would go a long way to protect the entire angling resource of the Tyne for the Association and more importantly for future generations of local and visiting anglers. Healthy migratory fish resources can be of great added value to property owners but only as and when these resources can be shown to be prolific. The Associations plans will eventually achieve this improvement so it too should also share the benefits from all its own good and hard work.
Finally, when the long-term management plan is agreed and set down, the Association with the aid of its advisors, will then be in a position to be officially consulted by the planners. Consultation with the planners will be essential on any future development plans within the Tyne catchment. The Association with its qualified opinion, will then be able to identify, comment and advise on any adverse impacts that “planning” may have upon the quality of the entire aquatic environment.
I wish the Association all success in its objectives.
