"Himeji masu" in the Town


Recent travels to Japan (For a holiday-cum-martial arts competition!) revealed a wonderful example of how urban rivers can thrive and be valued by local residents. In Matsumoto, a medium-sized city in the Nagano prefecture, an engineered channel runs alongside the uptown streets and within it flows the stream known as the “Metoba gawa”. Whilst it is true that the river channel is, overall, constrained within these engineered limits to control flood risk– the authorities have retained the excellent natural substrate and allowed/encouraged natural processes of stream bed erosion, deposition and marginal vegetation development in the base of this channel. The bankside vegetation behind the marginal strip is kept to a low enough level to allow pedestrian access via regular strimming. Consequently, there is a reasonable balance between human access, mown low-level flowering plants and grassland vegetation (supporting many butterflies and other invertebrates) versus more “shaggy” vegetation that overhangs or emerges from the wetted margins and varied in-stream habitat arising from the good gradient and natural substrate. The water quality appeared to be excellent in this stream, whose source is in the mountains overlooking Matsumoto. The clear glides, riffles and pools were all visibly heaving with fish of many kinds.

Pods of Carp, shoals of small dace-like fish and even trout could easily be spotted from the bridges and bank-side paths. Even more striking to me, in my professional capacity, were the utter lack of fly-tipping and the broad cross section of society who used the riverside to relax at lunchtimes, walk their dogs and generally pass the time of day.
An approach that mirrors advice commonly given to my UK Trout in the Town projects is the use of cheap, easily replaced interpretative signage. Treating such signs as “consumables” for UK projects (to be replaced when defaced, damaged or lost) allows important messages to be continually and cheaply advertised; and highlights the utility of cheap materials. Although a similar approach is used in Japan, it would seem that the “life-expectancy” of their signs would be generally much longer.

The lady owner of the guesthouse that I stayed (Maruma Ryokan, Matsumoto) very kindly explained to me that, being in a mountainous region and far from the sea, the local people actually ate freshwater fish. This is seen as very strange in most areas of Japan – where seafood comes from the Ocean! The local name, she told me, for the delicious (!!!) little trout that I was served for breakfast was “Himeji masu” which she translated for me as “Princess trout”. Alongside the sticky rice, pickles, miso soup, green tea and fantastic fresh fruit, it made for a deeply wonderful breakfast!
Later on in that day, I was able to reflect on how catering for urban green spaces and the wildlife within it allowed the Matsumoto residents to be so connected to their river. Like all good Japanese reflection, this was undertaken in a hot bath – in this case outdoors in scalding water from hot volcanic springs and surrounded by bamboo forests, dragonflies and sunshine. It is a hard life sometimes.

Trust me this is a trout (in the middle of the frame)

Great blog, Paul.

Really interesting shaggy channels.

You sure that's a trout?

And that reminds me, I got to start a blog too...

Cheers Simon (you cheeky git; a video would have been better proof of trouty goodness. I may not be the brightest, but it was spotty and had an adipose fin!!)

so good to see the respect and intelligence the Japanese show to their watercourses.
The first insect I saw when I was over there was a mayfly!!
Good positive stuff. Thanks, Paul

First Survey Record of Wild Trout Returning to Lyme Brook Habitat Works Site!

You may have seen the first three phases of works on the middle reaches of the Lyme Brook (shown in previous blogs Here and Here) from project works that began in 2015...

Well although the first surveys after that work found some nice coarse fish populations - there was no cold hard evidence that any trout had found the newly-improved habitat...Until now!
I received a phone call today from Matt Lawrence who is the EA's Catchment Host for the Trent Valley Catchment Partnership (with key partners Groundwork West Midlands and the Wild Trout Trust who conceived and delivered the habitat works). Matt told me that he'd had some exciting preliminary reports from a EA Midlands fisheries surveys team. Their survey on 7th September had caught several wild trout as part of their sample on the habitat works site.
These are the first modern records of trout in the brook and is also the exciting news that we have been waiting for on these first phases of work to create spawning, juvenile an…
Catching and Releasing the first Fly-Caught wild trout from a stream that was dug out of a city-centre pipe was probably the highlight of 2016 for me!

Buried in a brick tunnel under England's industrial developments of the 1800s, a section of the Porter Brook in Sheffield was brought back to the surface by a bold project co-ordinated by Sheffield City Council and involving the Wild Trout Trust, The Environment Agency and many more partners.

You can now witness the actual process of freeing the Brook from its pipe - and the creation of functioning trout-stream habitat in this short video.



Yet, the above video does not show the completed park that was a huge part of the entire project - and it does not show the planted vegetation beginning to develop in the summer of 2016. And, it does not show any fly fishing or video of a trout capture...

But the film, below, that was made by the excellent Huckleberry Films as part of the Canal & Rivers Trust "Living Waterways" awar…

A previously buried section of stream produces the first fly caught trout in >160 years

As near as I can work out from the archaeology report, this section of river - recently brought back to the surface in dramatic fashion by Sheffield City Council, the EA and the WTT partnership - was buried in a low brick tunnel somewhere around 1853 to 1868. The northern half of the site was certainly buried underground BEFORE the time the 1853 map was produced....and the rest of the brick tunnel was placed over the top of the stream before the map of 1868...

Of course, it is not easy to tell what the water quality was like in that section even BEFORE the stream was buried...and whether there were trout surviving in the stream when it was sealed underground...

What is damned sure is that you couldn't wave a fly fishing rod around in that underground tunnel once they'd built it!

This was still the case until the completion of the massive project to remove the brickwork and create an attractive "pocket park" in the city centre. You might have seen from This Previous …
