Boat trailers should be inspected. Boat propellers are often the culprit, check closely. Even if you are fishing from a dock or a bank, check and clean the equipment after each outing and before you move to a new body of water
2. Try to launch from areas free of aquatic weeds for at least 150 feet and with good facilities on site for proper cleaning after an excursion.
3. Take a close look at the area where you launch from, and return to, as well as the area where you fish. If you notice any unusual weeds, map or mark the place, and contact the proper authorities. The area should be inspected, and if found to be infested with an exotic species, it should quarantined and given the appropriate treatment.
4. Avoid dumping the contents of fish bowls and aquariums into areas where they could end up in a pond, lake, river or stream. This, it is suspected, is how the hydrilla problem began in Florida, and spread through the rest of the country.
