Zebra Mussel Control – Emergency Adoption Preamble

| August 5, 2012

This just came across to Texas Fly Caster, and now you can see government bureaucracy in action. Amazing how many words it takes to say something like this, isn’t it? As much as this sounds like an “emergency,” it really doesn’t “contain” the menace. If boaters don’t have to wash their boats and trailers, it’s all over but the shouting. Is anyone out there interested in going into the boat wash business? I have the technology ready for viewing. It’s just a matter of finding a money person. In the end the State of Texas will be picking up much of the initial tab anyway. Anyone boating on these infected lakes should be WASHING THEIR BOATS AND TRAILERS VOLUNTARILY RIGHT NOW.

ZEBRA MUSSEL CONTROL EMERGENCY ADOPTION PREAMBLE

1. Introduction. The Texas Parks and Wildlife Commission adopts, on an emergency basis, an
amendment to §57.972, concerning General Rules. The emergency action adds Lake Ray Roberts and Lake Lewisville to the list of water bodies under special regulations intended to control the spread of zebra mussels (Dreissena polymorpha).
The department earlier this year amended §57.972 to implement special regulations to control the spread of zebra mussels from the Red River and Lake Lavon (37 TexReg 3602). Under ordinary circumstances, the department would consider any person in possession of zebra mussels (including veligers) to be in violation of Chapter 57, Subchapter A, which prohibits the possession of exotic aquatic shellfish, including zebra mussels. The special regulation provides that the department will not consider a person in possession of veligers to be in violation of the exotic species rules, provided all live wells, bilges, and other receptacles or systems capable of retaining or holding water as a consequence of being immersed in a waterbody have been completely drained prior to the use of a public roadway. The rule also provided that a person traveling on a public roadway via the most direct route to another access point located on the same body of water would not be required to drain or empty water. The emergency action would extend the applicability of the current regulation to all impounded and tributary waters of the Elm Fork of the Trinity River above the Lake Lewisville dam. Zebra mussels were confirmed in Lake Ray Roberts on July 17, 2012 and in the Elm Fork of the Trinity River upstream of Lake Lewisville on July 18, 2012.
The zebra mussel is a small, non-native mussel originally found in Eurasia. It has spread throughout Europe, where it is considered to be a major environmental and industrial menace. The animal appeared in North America in the late 1980s and within ten years had colonized in all five Great Lakes and the Mississippi, Tennessee, Hudson, and Ohio river basins. Since then, they have spread to additional lakes and river systems.
Zebra mussels live and feed in many different aquatic habitats, breed prolifically, and cannot be controlled by natural predators. Adult zebra mussels colonize all types of living and non-living surfaces including boats, water-intake pipes, buoys, docks, piers, plants, and slow moving animals such as native clams, crayfish, and turtles. The U.S. Fish and Wildlife Service has estimated the potential economic impact of zebra mussels to be in the billions of dollars.
Zebra mussels affect natural ecosystems both directly and indirectly. The greatest direct impact relates to the mussel’s feeding behavior. Zebra mussels are filter feeders and process up to one liter of water per day/mussel. During this process, every particle in the water column is removed and either eaten by the mussels or coated in mucus and ejected. Unfortunately, the material removed from the water consists of other live animals and algae that supply food for larval fish and other invertebrates. In response to this changing food supply, indigenous populations of some animals decline and food webs are disturbed or eliminated. Once zebra mussels become established in a water body, they are impossible to eradicate with the technology available today.
What makes zebra mussels particularly difficult to control is that they have a free- floating, microscopic larval stage called a veliger. Because young zebra mussels are so small, they are spread easily by water currents and can drift for miles before settling. After settling, the mussels attach to hard objects and remain stationary as they grow. They often attach to objects involved in human activities, such as boats and boat trailers, and are inadvertently moved from one water body to another by people. Any water collected from waterbodies where zebra mussels are present could contain veligers; thus, water transported from waterbodies with known zebra mussel populations is a vector for the spread of zebra mussels.
For these reasons, the Executive Director of the Texas Parks and Wildlife Department finds that zebra mussels present an immediate danger to species of wildlife regulated by the department (specifically, all indigenous aquatic species whose food supply and/or habitat quality could be altered by zebra mussels, which includes game and nongame fish, nongame aquatic wildlife such as turtles, and mussels). The need to prevent the spread of zebra mussels from Lake Ray Roberts and Lake Lewisville to additional impoundments and drainages creates an imperative necessity to engage in
emergency rulemaking. The Executive Director also finds that due to the potential for the rapid spread of zebra mussels, it is necessary to adopt the rules with fewer than 30 days notice. As a result, the emergency rules will take effect immediately.
The rules are adopted on an emergency basis under Parks and Wildlife Code, §12.027, which provides that if the commission or the executive director finds that there is an immediate danger to a species authorized to be regulated by the department, the commission or the executive director may adopt emergency rules as provided by Government Code, §2001.034. This rule will continue for no more than 120 days from the date this notice is filed with the Texas Register. It is the intent of the department to also propose a non-emergency rule addressing the subject matter of this rule, pursuant to the provisions of Chapter 2001 that, if adopted, would go into effect before the expiration of the emergency rule.

(5) for any person to use game fish or any part thereof as bait, except for processed catfish heads used as crab-trap bait by a licensed crab fisherman, provided the catfish is obtained from an aquaculture facility permitted to operate in the United States. A person who uses catfish as bait under this paragraph shall, upon the request of a department employee acting within the scope of official duties, furnish appropriate authenticating documentation, such as a bill of sale or receipt, to prove that the catfish was obtained from a legal source;
(6) for any person to possess a finfish of any species, except broadbill swordfish, shark or king mackerel, taken from public water (salt water or fresh water) that has the head or tail removed until such person finally lands the catch on the mainland, a peninsula, or barrier island not including jetties or piers and does not transport the catch by boat;
(7) for any person to use any vessel to harass fish;
(8) for any person to release into the public waters of this state a fish with a device or substance implanted or attached that is designed, constructed or adapted to

    It’s about time to create a site devoted to the zebras. So you have to drain your bait wells and bilge? Who’s watching? No one.
