If the pond was artificially overstocked for fishing purposes, most of that will have died off by now, in favor of a population that can sustain itself.
You might ask the forestry service if they can do something about the pond. They'll likely know what the best fish to add to eat mosquito larvae would be. They may also be able to tell you if they're aware of any illnesses or pollutants affecting the local amphibians, or even send someone out who's an expert in frogs and can try to figure out the problem. Amphibians are what are referred to as indicator species- they're often the first to die off from pollutants, so absence of them can mean something is badly wrong.
Humanity as a species is only beginning to scratch the surface of how ecosystems work. It's a web of enormous, beautiful, near-incomprehensible complexity, including on a microbial level (true topsoil, for example, is a living network of bacteria and fungi centuries in the making, not something the garden center can sell), and even an expert would struggle to predict what impact adding or removing a species might have, unless they've already seen that species added or removed in a similar environment elsewhere. Hopefully the folks at your local forestry service are good at their jobs and will already be familiar with what your land might need.
Your idea of more habitat for native frogs and toads is definitely a good one. That's a good bet for any sort of wildlife and any attempts to get the local ecosystem back in proper order; habitat. Places to hide, good, clean water, as many native plants and as few nonnative plants as you can manage. Have any reasonably large rocks you've removed from somewhere? Pile them up in a heap full of crevices near some clean water (by "clean" I mean "not poisonous or polluted", not "clear and free of algae or mud"- tadpoles love algae), and you should have all the amphibians you could ever want once they find the place and multiply.
Leaving dead trees in place, whether standing or fallen, is often also a good idea, as rotting trees provide habitat for a large number of species. Woodpeckers, owls, and other cavity-nesters in standing dead trees, snakes and other beneficial reptiles (and amphibians!) in fallen dead ones, beneficial insects in both. That's a sort of mini-habitat that gets neglected a lot, with people hauling away dead trees before they can rot and be worked back into the soil.
And that’s all I’ve been catching with little fish. It’s fair to say that saltwater catfish will eat anything, people around here kill them, hardhead catfish to be exact, they’ll eat anything and they are all over the bay around me, they have become a real problem in the run off’s, the bay, anywhere where there is nothing but mud on the surface area underneath the water. I have even encountered them in the matagorda river, but to be completely honest there is mud there too. Texas has its good fishing seasons, AND it’s worst, but that doesn’t stop me from fishing!
I also know that redfish, black drum, shark, trout; "sand trout and spotted sea trout" have random run through’s, it’s not a consistent pattern where the fishing will be great during the same time of month every year, my neighbor still doesn’t want to believe me, that’s probably why he doesn’t catch anything worth eating. I have realized catfish aren’t in the bay, both gaftop and hardhead catfish are gone for the cooler months, while trout are all over the place at night under our green light, redfish usually bite in the morning as soon as the sun comes up, all the way until it is right about noon, they love mullet in the very cold months. I’ve also used a brand of bait called Fish bites, you cut em’ into small bite size pieces (they’ll come in a plastic package either labeled under shrimp or crab, and they include 2 colored strips) and I’ve caught black drum that people around me think it’ll take a lot longer to bring in, usually around the 20-38 inch mark. I’ve also caught a lot of trout, shark with these little bite sized baits.
I get that I was really off topic, I just thought I would share…
