The aim of the Sussex Ouse Conservation Society (www.sussex-ouse.org.uk) is to protect and enhance the biodiversity of the Sussex Ouse catchment area. During the summer the Society has been restoring habitat to the various streams that feed into the river. One of the aims has been to restore the natural pool and riffle systems dredged out in the last few decades. This video shows a section of stream where the society added gravel.
It has been very gratifying to see that this winter the magnificent Sussex Ouse sea trout have used the new gravel for spawning. The majority of the sea trout (which can weigh up to 13lb) leave the sea in late December/early January, hurtling up the river into the small streams, spawn and then return to the sea, often within 24 or 48 hours. The society is hoping that our work will help increase the dwindling numbers of sea trout towards levels seen in previous decades.

Excellent video of sea trout making redds on the gravel. Very good to see!
