Invasive Species

Brought to you by:


all visible aquatic plants from watercraft and trailers as well as waders and boots.


equipment (boat bilge, ballast tanks, bait containers, motor) before leaving any water access area.


of unwanted live bait (minnows, worms) in the trash.


In most cases, new fish species that are introduced into our waters don’t survive or present a problem. But some may flourish and potentially cause ecological or economic harm. When there is harm, these species are called invasive. Currently, we have several species in our waters that we are tracking as potentially invasive and the department could use your help to document new sites. If you catch something you feel is unusual, please call 302-739-9914. If you catch a Northern snakehead, blue catfish or flathead catfish please do not return it to the water, but kill it and contact us. Document the catch by freezing it or taking a good photo.

Regulations in red are new this year.
