Devils, Simone, North America discussed on Let's Talk Pets
Dot com. we're back continuing our conversation with my guess bear creek director of animal husbandry maritime appear in norwalk so barrett you're giving us a little bit of the history of desert fishes in the southwest so as you mentioned probably coming from the same maybe species millions of years ago what kind of biology commonalities do they have because of the desert habitat and maybe then we'll talk about some differences after there's quite a few similarities and and quite a few differences as you would expect most of the smaller groups that we're working with most the smaller fishes we're working with and aquariums and that a lot of hobbyists and dedicated individuals have at home tend to be the little diminutive fishes the publishes the kids alive bears now that being said there's quite a diversity of fish in the deserts of north america we have four desert's the sonoran the chihuahua on the mojave and the the great basin four different desert's four different climates different levels of Tipitapa implant fauna and everything else. So we have a wide variety about one hundred and sixty five species total, which includes some larger species minnows, some salmon's, Simone. There's quite a few about six species of endangered soman and in the American west. So the diversity in terms of taxonomy is huge. There's a lot of different types of fish for the ones that we tend to focus on in aquariums and keeping aquariums. There are some, some similarities, these guys all come from usually springs, or small spring, fed rivers, because that's often the only source of water in the desert, so they tend to like, very, very hard water. Sometimes a little bit on the cooler side, because they are from springs, most of them are Navarre's. They eat a lot of insects, but also plant material. So there's quite a few similarities there in their biology and their behavior there. Also, most of them most of the published fishes tend to be fiercely territorial, which is actually how they got the name pup fish. It was thought that they looked the males looked like a puppy chasing each other around, because the males can be fiercely territorial and beat up on not only each other, but also on the females. once they finished breeding so that's kind of how they got the name the kids are a little bit more peaceful they tend to behave very much like the live bearers they do well in large groups they're not very territorial they cohabitate very nicely are generally a peaceful fish in there also the goods are also live bears like the steelers so we're going to talk now a little bit about maybe some of the issues with with the desert fishes which and be a lot of them so maybe you wanna just talk about some of the more important ones which desert visions are listed as threatened or endangered in y sadly quite a few there's ten counties in the western u._s. that have more than five endemic endangered fish species there's over forty counties that have three plus endangered endemic fishes as highest rate of endangered fish species anywhere in the country despite the fact that diversity is a lot lower than say the southeast so there are quite a few endangered there's over sixty endangered species threatened or endangered listed at the federal level or at the state level and there's probably even more than that South of the border in Mexico that we don't have a great sense on. They don't have the same protections in many sense, south of the border that they have in the US. So there's quite a few species, there that we just don't know about they may be in trouble who's quite a few that aquariums have rescued and it propagated in order to keep them alive as living arc because we knew they were going extinct in their habitat was being destroyed with there's a huge number out there probably the poster child for endangered desert. Fishes is the devils hole up fish, if you will devils hole up fish you'll find out a lot about this US fish and Wildlife Service has been doing a fantastic job trying to keep these alive and they were actually oddly enough. These guys worthy center of the first supreme court case to challenge the Endangered Species Act back in the nineteen seventies like I said, a lot of these are spring, dwelling fishes they live in groundwater. So when we pump out huge amounts of groundwater to have agriculture in places where agriculture doesn't normally exist like the west we ended up driving the water level down in those springs and destroying.
