Invasive plants, fish and mussels cost money and wreck habitat once they take hold, and fishing and boating are two ways they travel. The good news from wildlife agencies is that these invasions are preventable, and a few habits you can repeat after every outing.
How hitchhikers travel
Aquatic invasive species can ride on hulls, propellers, anchor lines and trailers. Others survive in bilge water, livewells, motors and bait buckets, or hide in mud on boots and waders. One organism, or even a piece of a plant, can be enough to start a new infestation. Zebra mussel larvae are tiny and nearly invisible, which is why draining matters as much as looking.
The routine
- Clean: remove visible plants, animals and mud from everything before leaving the access point.
- Rinse: use high-pressure hot water on hulls when possible, and low-pressure water of at least 120 degrees Fahrenheit inside boats. Flush motors for two minutes or as the owner manual directs.
- Drain: empty the motor, bilge, livewell and every container that can hold water before you leave the launch.
- Dry: leave gear out for five days minimum, or at least wipe it down with a towel first.
Extra steps for anglers
Toss leftover bait, worms and fish scraps in the garbage. Bait you plan to keep alive should sit in fresh spring or dechlorinated tap water, never in water scooped from the lake. Do not carry live fish or any other creatures between waters, even with good intentions.
Make it automatic
Do the routine at the ramp every time, including when you are leaving a lake you know well. Wading gear, nets, anchors and sandals count as equipment too. Check your state wildlife agency for local rules, since some require boats to be drained or inspected.
