Can you collect invertebrates in Kansas? In Ohio, where I lived until very recently, all of the bivalves were off limits. It was illegal to mess with them in any way.

Erica, you can oly collect (keep) mussels in Kansas if you have a collecting permit. These were collected, tagged, and released for a study we are doing on cylindrical papershells in Kansas. You can go "mussel grubbing" and release everything you catch just as long as you have permission on the property. I believe dead shells of all species can be kept as well regardless of conservation status.

This varies some by state, I know that in some cases, it is illegal to possess any... including relic shells.

Yes, in Kansas you can collect shells but in Missouri you cannot keep any shells unless you have a collecting permit. You cannot keep shells of species of conservation concern even if you have a collecting permit.

In many states the "no collection of any valves" rule is related to the shelling industry, and the surprisingly large number of poachers on the edge of this industry. The primary market for North American mussel shells is east Asia, as part of the pearl industry. Those people will buy them no questions asked, of course. In states like Alabama north to Ohio, where there has been and to some degree still is a legitimate industry, the "no collection" policy is part of the legitimate management and protection of mussel populations, since someone with a car full of shells could say, "I'm just collecting them for fun". There's a sad sociology of who the poachers are, in Kentucky and Ohio they're almost invariably from Tennessee and Alabama. So in states with the historic big river shell industries this is a legitimate concern.

That is a very unscupltured Quadrula. Pretty neat. Even when that small I've only seen them heavily sculptured.

Or is that an alberti? Only seen a few large shells and that just came to mind.

Caught my attention too, although I'm pretty sure that's a Q. quad. Definitely not C. aberti.

Those pigtoes in the background of the first pic are pretty interesting too. Don't know why you'd focus on the cylindrical mudhoneys for your topic

Yes, in Kansas you can collect shells but in Missouri you cannot keep any shells unless you have a collecting permit. You cannot keep shells of species of conservation concern even if you have a collecting permit.

Or, alternately, in Missouri, "With a fishing license, you may take five non-endangered mussels a day for your use." (MDC website at this page: http://mdc.mo.gov/co...ussels?page=0,4). Possession limits are double daily limits and 2 shell halves count as one mussel, even if the shells are empty.

Gotta love the laws!

Those are unsculptured Q. quadrula. There are also no pigtoes in the picture (they are also Q. quadrula). These came from fine gravel and sandy streams. Here, in central Kansas, Q. quadrula are much more smooth than other rocky streams within Kansas. We chose cylindrical papershells for the study as they are restricted to central/western Kansas as most species of mussels in the state are restricted to eastern Kansas where there is much more water. The unique association to central/western kansas for this mussel is unique. The cylinders are also a species of concern within the state.

Neat stuff! So the cylindrica are disjunct from other eastern populations? Do you have a map of their distribution in the Plains? I would love to see it.
