Caught in Sarasota Bay, in the Mangroves

Are all 3 of these Gulf Killifish, just different genders?

I'm certain this is a type of Mojarra fish but not sure exactly which one

3 killis are all gulfs Fundulus grandis. The mojarra is more difficult. It is definitely a Eucinostomus, but there are about 5 different species it could be in Sarasota and they can be a real pain to ID without looking at some details under a microscope or doing some body measurements, especially if they are under 40 mm standard length.

Thanks for confirming the Gulf Killies

I kept the small Mojarra in case more would be required for an ID, so I can do try to count fins or something like that

for the mojarra, you'll need to look at the scale patterning on the snout between the upper jaw and the eye

I just checked out the Mojarra, it's pretty decently preserved but it's hard to make out the type of scale patterning in that area? Is there another way that you know of?

Like associatedboy said it could be any of 5 similar species, Eucinostomus mojarras are really difficult especially when small. PM me your email address and I'll send you a publication that may help you ID these mojarras. Once you know what to look for it isn't too bad.

does anybody here have the means to ID this mojarra in a lab with DNA or something like that? Is that possible? I'll pay whatever the cost (well unless it's crazy expensive or a huge ordeal) . I was unable to ID based on the overhead view of the head probably because it faded. I was going to just let it go as unidentified , but I really want to know what it is haha, thanks in advance

Very true Doug, and may this be a message to the sea animals out there...If you bite Fishy Jackson's hook you will be identified any means necessary

FishyJackson - would you be willing to share the process you went through to get the fish ID'd? For example, did you submit a fin clip or the whole preserved fish? Did you do any preparation yourself (chemicals, primers, PCR, etc.) or did you let the lab take care of the whole process? What were the steps the lab took (e.g., PCR, sequencer, etc.). If you were to do it again what would you differently? Thanks.

thanks Michael- You're right I need to upload an avatar pic. Will get on that

Lilyea- The fish was only 2 inches long and it was dried out, so I just sent it in to the lab whole. The lab took care of the whole process. The company actually does the DNA tests for seafood, so this was a special request and they were nice enough to do it for free.
