571—90.3(456A) Restrictions.
	90.3(1) A person shall not possess, introduce, import, purchase, sell, barter, propagate, or transport aquatic invasive species in any form in this state, except:
	a. 	By written permission of the director;
	b. 	For disposal as part of a harvest or control activity;
	c. 	When a species is being transported to the department, or to another destination as directed by the department, in a sealed container for purposes of identifying the species or reporting the presence of the species;
	d. 	When the specimen has been lawfully acquired dead and, in the case of plant species, when all seeds are removed or are otherwise secured in a sealed container;
	e. 	In the form of herbaria or other preserved specimens;
	f. 	When a species is being removed from watercraft and equipment, or when a species is caught by an angler and immediately returned to the water from which it came; or
	g. 	When an individual angler possesses a species that has been caught and immediately killed.
	90.3(2) A conservation officer, other licensed peace officer, or employee of the department may seize or dispose of all specimens of aquatic invasive species unlawfully possessed, introduced, imported, purchased, sold, bartered, propagated, or transported in the state.

	90.4(1) Designation of infested waters. The department shall designate infested waters of the state.

At any time, the department may designate additional waters or remove from designation those waters that are no longer infested.
	90.4(2) Restricted activities on infested waters. The department may restrict boating, fishing, swimming, and trapping in infested waters of the state. When determining when to restrict activities in infested waters, the department shall consider:
	a. 	The extent of a species’ distribution within the state;
	b. 	The likely means of spread for a new species; and
	c. 	Whether restrictions specific to infested waters containing a specific species will effectively reduce that species’ spread.
These rules are intended to implement Iowa Code section 456A.37 as amended by 2004 Iowa Acts, House File 2357.
