Volunteers are being sought to help with the river esk salmon and pearl mussel regeneration projects.

Quote
MORE muscles are needed to help the endangered freshwater pearl mussel in the River Esk.
The North York Moors National Park Authority is looking for extra pairs of hands to assist with the practical work for a project looking to improve conditions for the resident freshwater pearl mussels and salmon in the River Esk. Volunteers would get involved in a range of tasks including river habitat restoration and water sampling.

Anyone interested in helping out is invited to attend a presentation about the project at 7pm next Tuesday at the Fox and Hounds Inn in Ainthorpe.

I went to this meeting last night and it was interesting stuff.
There is a lot of work being done to improve silting on the river such as installation of cattle-proof fencing around the river and bank improvements.
The authority is building good relations with the farmers and trying to ensure that such improvements have no negative effects on the farmers grants etc.
The mussels themselves are very slow growing and live a long time (30+years with ease). The stocks have been historically damaged by pearl fishing but apparently it can mean shelling up to 500 mussels sometimes to find one pearl so the effects of this were quite devastating.
They are completely reliant on the presence of migratory fish as when in larval stage they latch on as a parasite to the parr.
There were a few different groups there including one that had done surveys on acidity and other factors in the becks and upper reaches of Esk- they had noted that salmon parr and stocks improved when restrictions were enforced on emissions from the coal fired power stations such as Drax and Ferrybridge and less acidic rain fell on the moor.
Lots of interesting angles from different people and a very positive thing for the river.

And one of the things they are researching is how quickly sediment drops from the water after a spate.
Now those findings should prove invaluable to any Esk fisher!!! wink
