Plants & pond environment
Protect the fish without creating a new hazard
Think about access, visibility and safe deterrents as part of the pond design.
Review the edges
Look for places a predator can stand or where fish regularly gather. Consider suitable barriers or netting that stays taut, secure and clear of the water and fish.
Check for trapping risks
Loose mesh can trap fish and wildlife. Inspect any cover regularly and design safe access for maintenance. Avoid sharp lines or improvised devices that could harm animals or people.
Do not use harmful deterrents
Keep poisons, traps and injurious devices away from pond protection plans. Seek appropriate local advice where wildlife creates a persistent problem.
After an incident
Check remaining fish for injuries and unusual behaviour, then test water if the pond was disturbed. Seek fish-health advice for wounds rather than assuming a superficial-looking mark needs no attention.
Review access around the pond
Sketch the pond edge, shelves and nearby landing or hiding places. Record when losses or visits occur. This helps you discuss a practical barrier or cover fitted to your own pond.
