What kind of shellfish are these shells from

When fishing at the Jordanelle reservoir me and my sister found a bunch of these shells on the beach near the Ross creek trailhead. They look cooked and we also found crawfish shells in the same location. As far as I know there are no shellfish in the Jordanelle reservoir so I figure that they were probably brought from somewhere else to cook bit the unusual thin is that each of these shells was a twin shell like the two in the pictures. I've never seen a shell like that before so I got curious about what they were.

Relocate catfish?

We need rain. These catfish are swimming around the surface and I'm concerned. I was going to fish them out yesterday, but a copperhead showed up. I waited for three hours. It's going to be 92 degrees today and no rain forecasted. What if anything do you suggest? This is a public lake so I can't shoot the copperhead. Are the catfish in distress?

Treating cyanobacteria

I have a half-acres surface pond. In the past few weeks it has been taken over by what I believe to be blue-green algae. I have applied over the counter Cutrine Plus and ordered Cutrine Ultra. I do not see any benefit from the Cutrine Plus application. I am waiting on Cutrine Ultra. I don't have a chemical license. A. Is the Cutrine Ultra the correct product? B. Based upon the limited information I am providing, do you recommend another course of action

Using fish for mosquito control in ornamental pond

Hello -
We bought a house in southern Vermont last year that has a small ornamental pond (about 20 ft x 8 ft & 3 ft deep). I prefer not to use pump recirculation, but I'm interested in using small fish for mosquito control. Any advice you can give would help (i.e., literature on this specific to New England, species, sources to purchase from, etc). I'm familiar with mosquitofish (Gambusia affinis), but I know they're not native to Vermont, so I expect they should probably not be an option for me. Any advice you can give would be appreciated & thanks.

Identify a mussel

We recently purchased property in Livingston county that contains a spring fed pond. Can you identify what kind of mussels we have in the pond? See the attached photos. Is a mussel this size the sign of a healthy pond? And what kind of wild life eats this kind of shellfish? Thank you!

Grass carp for farm ponds

Good afternoon. I have 24 different ponds throughout my property but was beginning to think about stocking grass carp in 2 of them to help control vegetation. The first one is a pond that is used as a "bait pond" as I call it to raise small fish to use in recreational fishing around home on several lakes and rivers. The second pond is just one that is used as a water source for a pasture of feeder cattle.

My 2 questions are if I do decide to stock grass carp in my ponds, what is the ratio to configure the amount of fish I put in the body of water? Is it based of of Square feet or another measuring method?

And what is the lifespan of these fish? How often would I need to restock them in my ponds?

Thank you for taking the time to look at my question.
