The FishWatch phone line provides a quick and easy way to report sightings or evidence of:
Aquatic pests and diseases
You can help to protect our valuable aquatic environment by reporting any aquatic pests or diseases (including fish kills). Note where and what you saw (with GPS coordinates and photographs if possible).
Illegal fishing
If you have seen something involving fish or fishing which doesn’t look quite right, the FishWatch phone line provides a quick and easy way to report it.
Illegal fishing could include someone netting in the river, exceeding their bag or possession limits, taking undersized fish, fishing in a closed area, having more fishing gear in the water than they should, or 
selling or attempting to sell recreationally caught fish.
Any information you provide about illegal fishing activity could be valuable, before you call make a note of:
How many people you saw.
Who they were. Did you hear/know any of their names?
What they were doing.
Where it happened; the nearest known landmark or intersection of the closest road may help to pinpoint the location of the activity.
What type of equipment you saw being used; the type of cars or boats, registration numbers, and descriptions.
When it happened - time and date. Is it something that is happening right now, while you are making a report, or was it something you observed previously?
Your reports are treated in strict confidence.
We recommend you do not approach anyone you think is involved in illegal activity involving fish or fishing. However, by reporting what you see you will be assisting us in protecting WA's fish resources for future generations.
If you don’t wish to contact us through FishWatch you can pass your information to one of our local offices.
