Improving future fish populations

A wooden baulk creates a better flow for fish to move upstream on Haltwhistle Burn

Every year, salmon and sea trout return from the sea to the ‘Mouth of the Tyne’ and swim upstream to lay their eggs where they were born. The journey is known as fish migration. However, there are many obstructions which stop them from doing this.

These obstructions are mostly a legacy of the industrial revolution and include:

  • Weirs which were built to provide power
  • ¬†Culverts created by building roads

Our aim is to open-up the river to as many migrating species as possible so we design and build both large-scale fish passes and smaller fish easements to help improve fish populations.
