- Hybrid lepomids, or common sunfishes, are tricky to ID. I'll show you how to go about finding the best possible ID for your fish. Fishing for sunfishes is a lot of fun, especially knowing that a hybrid could be lurking around. We will cover the wargreen, a hybrid between the warmouth (Lepomis gulosus) and green sunfish (Lepomis cyanellus).

Hybrids are tough to ID. Even I encounter hybrid specimens that I just can't figure out; and obviously submitting each hybrid to a DNA analysis would get expensive! So don't feel bad if you can't come to a fairly certain conclusion as these hybrids often stump us biologists working with these fishes.
These videos are just so well done and produced. The content is second to none, but also the photos, infographics, animations. Just so well done. Keep it up these are very interesting videos
Thanks once again Ian! It definitely makes the lengthy production process easier knowing there are people like you that can appreciate them and it helps ya out.
Great running commentary. I felt like I was there.
Thanks Barbara! But I have a feeling TH-cam skipped you off the carp video maybe and went to the hybrid ID?
Glad I found this video. I have both redear and bluegill in my local lakes and it was awesome to find out that most of the "bluegill" that I've been catching are actually readear/bluegill hybrids
Ah, very glad to help there. Yeah...those redear/bluegill hybrids are sometimes the trickiest to ID. Cheers!
Very interesting! Love the logic of identification.
Thanks Sarah. It is fun going about the process.
As with your others, this is a very well-done video.
Thanks again Mathew!
Good videos. Thanks for taking time to produce them.. Fish or fishes can technically be used different ways. My fishery professor always said if they are alive they are fishes if they are dead they are fish. Fishes can be used for the plural or collectively as fish. Jack B. needs more education.
Appreciate that nav7icula! Not sure where your fisheries professor got that information from. Odd.
How would you identify non breeding males that don't have as distinctive coloring? There are a lot of different distinctive markings between each species but some are fairly similar to the point you're nearly relying on the colors for identification. I'm very new to this and was wondering if it's difficult to ID females or if I just need to get out there and put in the time to learn the smaller differences
It's a good question Chase. And it can actually be very complicated to ID males from females within certain species, sometimes even within breeding season.
There are a couple of problems because certain species of lepomids like your bluegill will have males that develop to mimic a female's resemblance so as to later gain access to a nest by tricking a parental male. These satellite males will not take on the appearance of a parental male with that bright red/orange breast and instead look just like a female.
Outside of breeding season, it's usually necessary to examine the size of the urogential opening to better guess the sex; even then that's not always 100% reliable. I put up a comparison photo on my bluegill page of the urogential opening: www.koaw.org/bluegill .
I think I’m responding to this vid feature for the second time.
My question this time is, is it possible for a population of bluegills to completely absorb another species of lepomid into their gene pool? So much so that there are no specific good examples of an introduced species, but a healthy population of “native” bluegills that clearly exhibit traits of other lepomid; specifically, green sunfish & pumpkin seeds?
Interesting question Roger. It is possible for populations of lepomids to acquire traits from other lepomid species via hybridizations and then the subsequent passing along of genetic code; some of those acquired traits could linger in those populations indefinitely. But to completely absorb a genome of another lepomid is impossible. The speciation (splitting of species) has already occurred--there is no reason (at least in my view) as to how this could occur.
Scientific info is good, but everything else is shit! First of all is "fish" not "fishes", Second what is a "fisher"? That would be "Angler"
Ah, finally! Normally I delete comments that are inane and ignorant but you may offer a good example. You're so confident in your ignorance. I will just say that you're quite wrong and I'll let that stew with you. Cheers Jack!
It may be a unpopular opinion but I personally love how he calls them "fishes" it's iconic 😂 I know I'm a little late to comment this, but Koaw produces very educational videos, dont try to bother him 🙂
Cheers
