3 more months of the 2013 season

Wednesday, August 7th, 2013

These bulletin blogs represent news about Finavon and the South Esk, and my views as a riparian owner. While I may digress at times to write about other places, these are not the views of any other organisation, nor are they designed to promote the interests of any individual or organisation other than Finavon Castle Water and factors affecting the fishery.

It has been a very poor season for catching sea trout on rod and line at Finavon. As I write this bulletin on the 2nd of August, our total catch is 13 sea trout so far this year. To put that in perspective, that is the lowest ST rod catch at the end of July at Finavon for more than 30 years. Our local rods have fished hard, some of them all night through on a number of occasions. As catch reports came through, and our syndicate members realised that sea trout were not being caught, morale dropped, resulting in fewer visits to the river.

Beeches Pool (Castle Beat) from the Aqueduct

The photo above shows Beeches in low water. After winter floods in 2012/13 eroded the south bank above and below the Aqueduct, Beeches came into its own, as well as the deeper water at the head of Haughs Pool. Throughout the season these pools have been occupied by salmon and sea trout. As I write this blog there is a nice shoal of grilse that can clearly be seen from the Aqueduct, but my guess is that they are virtually uncatchable! 

Low angling effort has therefore almost certainly been a factor in the poor returns, and the extended low water and high temperatures throughout July have also contributed. Other beats such as Cortachy and Inshewan have had better returns than FCW, but in general seatrout catches on the South Esk have been poor this year. Another factor in our catch returns is that very few of our anglers stay through the night. In former years most of our seatrout were caught in the pre-dawn period which I suspect is being unfished this year. I have learned to take a philosophical view of catch returns, although I accept that many people make decisions based on numbers displayed on Fishpal. The points as far as I am concerned are that the river is in good nick (which generally it is, although I acknowledge there are problems, many of which I have written about in these blogs) and also that there are fish in the river.

As I continue writing this blog on 7 August I note that there are some fresh grilse at the head of Haughs and that Derek and I accounted for three salmon (all returned) in the recent freshet. There is observational evidence that there are some new fish in the river, and their numbers should start to build up as the late summer progresses. As far as sea trout are concerned, the season is over – bar the shouting.

Last night I was invited for an informal chat with the Kirriemuir Angling Club committee. It was an interesting discussion, mainly but not exclusively on the subject of the mixed stocks coastal nets at Usan. Not surprisingly, there is a high level of frustration within the committee on the apparent powerlessness of the Fishery Board in a) monitoring b) enforcing the weekly netting slap times (from 1800 on Fridays to 0600 on Mondays throughout the netting season). The fact that noone knows what is happening makes the matter appear bigger than it should.

This photo shows Harry’s Bar at a nice height for a late summer grilse or salmon. It was in this pool that Derek caught a nice salmon in early August and lost another before leaving for fishing duties in ‘another place’!

My personal view is that ‘keep-ins’ (when the netsmen decide for reasons of ‘safety’ to continue fishing throughout the statutory slap period) should be in the public domain and published weekly by the board. It seems extraordinary, however delicate the behind-the-scenes activities of the fishery board, that in this day of freedom of information we are in the pre-computer age as far as being kept updated is concerned. It would be interesting to see if under FOI this information should be in the public domain.

I will write more fully on the evening spent with the KAC committee in my next blog.

In the meantime, if any of my readers can spare three or four hours next Sunday to help with pulling out Himalayan balsam plants we are meeting at my house at 1100. Beer and sandwiches and a day’s fishing in the autumn for anyone who comes to Finavon to help our assault on the dreaded weed. We are NOT dealing with Giant Hogweed. That has already been done professionally. Please phone me (07748 634 658) if you can attend.

Sea Trout River?

Monday, July 22nd, 2013

These bulletin blogs represent news about Finavon and the South Esk, and my views as a riparian owner. While I may digress at times to write about other places, these are not the views of any other organisation, nor are they designed to promote the interests of any individual or organisation other than Finavon Castle Water and factors affecting the fishery.

The South Esk

A sea trout river first, and salmon river second; Is that a fair description of the river in 2013?

The South Esk has a long and deserved reputation as one of Scotland’s great sea trout rivers. In the 1960s it was not unusual for the total catch of sea trout and finnock in the S. Esk District to exceed 20,000. In 1967 the catch was 37,000. Only the Ythan, Deveron and Spey came anywhere close to matching these catches. As far as we know, the South Esk continues to produce good numbers of sea trout smolts, although recent years have seen a decline – possibly from competition for redds and juvenile habitat with salmon. Whether it is this, or marine mortality, which seems more likely, the last five years have seen a severe, but not unprecedented decline in numbers of returning adult fish. Nevertheless, the South Esk remains a top sea trout river.

I have often been asked why the South Esk is so much more productive as a sea trout river than its close neighbour the North Esk. As always with sea trout, there is no easy answer. The river has all the habitat requirements of the sea-going version of Salmo trutta L. – the brown trout, from gravelly upper tributaries to the deep pools and dubs with their quiet, alder-overhung tails. I have seen shoals of 200 – 300 sea trout averaging two and a half pounds in the Dam Pool at Kintrockat, and similar numbers in the Boat Pool at Finavon. But the most impressive show of sea trout that I have seen anywhere is in the Garden Pool at Inshewan. Less than a decade ago this single pool produced over 350 sea trout to night-fishing rods.

Unlike the great sea trout systems of the Western Highlands – Stack, Maree, Shiel, Eilt and Na Shealagh (all now ruined by reckless expansion of salmon farms), there are few big sea trout caught on the South Esk. The century average is just over two and a quarter pounds and the biggest I have ever heard of was a twelve pound fish caught at Inshewan. Sea trout of 5lbs and heavier have never been common.

Until recently the coastal nets South of Montrose continued to take a heavy toll of the South Esk’s sea trout stocks, in May June and July each year killing 2,000 to 3,000 fish, in addition to 6,000 salmon and grilse. But now the netsmen have agreed to return their catch of sea trout alive to the sea and they say that none will be sold. You would have thought that we should see more fish in the river as a result.

For anglers visiting the South Esk in June or July to fish for its sea trout, there is a culture of night fishing. There is a group of 30 to 40 anglers who home-in on this little river to fish for sea trout through the short summer nights, and witness the heavy splashes and spreading ripples made by these mysterious fish against a sliver of light in the night sky. The South Esk is (or was) defined by its sea trout. The essence of this little river is the experience of waiting beside a tree-lined pool at dusk for the colour to drain from the landscape and for the bats to start their incessant search above the water for flying insects. The lines of alders against the sky with the dark pools at their roots, and the slow, sometimes imperceptible, draw as a sea trout takes the fly, represent aspects of an angling culture that very few rivers can sustain, and the South Esk is one of these.

My view as a manager, not as a scientist, is that in the long term there is no reason why sea trout numbers should not improve. I say this on the evidence of an increase in terms of prey species biomass around Scotland’s coast, possibly as a result of recent colder winters. This increase has been recorded by SNH and marine biologists.  It appears that there is a similar trend in Ireland, the Celtic Sea and Northern England. We cannot be certain why there should be a sudden and unexpected increase in zoo plankton, phytoplankton, sand-eels etc.

What we can say however, is that further afield in the South Norwegian Sea, things are not looking so good with a collapse in herring, blue whiting and mackerel stocks. Interactions between salmon and other species tell us a lot about population dynamics, and gives us insights for explaining the condition of individual fish. To summarise; close to Scotland’s shores there seems just now to be plenty of food, but elsewhere the situation is at best patchy. Conclusion? OK for sea trout, not so good for grilse, and OK for 2 sea-winter salmon and the odd 3 sea-winter salmon that survives.

Temperature rises still further, & river level falls

Saturday, July 20th, 2013

These bulletin blogs represent news about Finavon and the South Esk, and my views as a riparian owner. While I may digress at times to write about other places, these are not the views of any other organisation, nor are they designed to promote the interests of any individual or organisation other than Finavon Castle Water and factors affecting the fishery.

In my last blog I mentioned the shoal of sea trout in Boat Pool. I have been away for a few days and, on my return, paid a visit to the Boat Pool again in bright sunshine. This time, in much more helpful light than on my last visit, I was able to make a rough assessment of the numbers of salmon and sea trout in the section of Milton Beat between Tyndals and Volcano.

Colin Gibb at Boat Pool

Colin Gibb and I surveyed the sea trout and salmon in Boat Pool on 21/7/2013.

As a result of that informal survey, where we could count numbers of fish lying on the bed of the river in about two thirds of the river width from the south bank, I estimate that there are about 200+ seatrout in that pool and about 20-30 salmon, all lying in the main dub of the pool immediately upstream of Volcano.

I tried to take some photos (see photo above) from which you can just pick out the grey shadows of little clusters of sea trout lying doggo on the bed of the Boat Pool. The salmon were more elusive, but you can just see one or two of them too – well, perhaps not quite!

Sanctuary for heat stressed fish

This photo shows the holding section of the Boat Pool in very low water. On 20 July 2013 there were more than 200 sea trout and between 20 & 30 salmon lying quietly in the deeper, shaded water of Boat Pool.

Conditions for catching sea trout at night have been good at times, but more recently, with the high daytime temperatures and rising water temperature, fish have been reluctant to take the fly. Sea trout have been seen in good numbers ion both Red Brae and Boat Pool, but the other pools on all four beats have shown only occasional fish. Some people will argue that the low catches reveal a disastrously small sea trout run.

While I agree sea trout numbers may be less than the abundance traditionally associated with the South Esk, I also acknowledge the capricious behaviour of sea trout in fresh water, and the lack of evidence of numbers, that are so vital to accurate stock assessment. I will continue to argue that fishery management based on guess-work is generally inaccurate and ineffective.

Until management of the South Esk salmon and sea trout fishery is based on sound stock assessment, we will continue to receive knee-jerk calls for hatcheries to be reintroduced to the river (as is happening as I write this blog). While there is certainly a place for hatcheries and stocking in the fishery manager’s toolkit, it should not be the first remedy to which we turn on the basis of one or two seasons poor rod catches. Perhaps the first step should be to have a management plan based on the best available assessment of numbers of salmon and sea trout? We can then identify which groups of fish are in a fragile state – close to or below conservation levels – and then take remedial actions in an organised, prioritised and realistic way to target those identified groups.

It is undoubtedly a poor year for sea trout rod fishing, but, as yet there is little evidence of a collapse in sea trout stocks: just an impression that numbers are low. So let’s get on with managing our little river on the basis of common sense & good husbandry, supported by science.
