Bighead carp in Birdland

Wish that I would have hooked into one of these before they removed them.

No doubt Curtis. I want to tie into one of thoes bad boys. Maybe they missed a few.....

Very strange. Iím not opposed to introducing them in more ponds but I wonder how they got there. 46lbs would be PB for me on any species. Good on the local angler for reporting it, I hope he had a blast making the discovery.

Im real curious how they got there too. Mainly found down south so someone must have caught some little guys and brought them to CO and let them loose. Wonder if they dropped any elsewhere in Arvada. Thats why we never know. We finally got a 10lb common there in 2020 and we saw some tanks up by shore...might have been the bigheads.

I'm by no means in support of invasive species, and I understand why they have to remove them but yeah those would have been fun to catch. In the article, CPW says all 14 of them weighed over 40lbs each! Again I'm not advocating here, but the article itself might fuel some bucket biology as it pretty much explains how easy it is, and included some motivational trophy pictures.

My understanding is that the Division of Wildlife put them in the pond. From the link ------ "The bighead carp was introduced in 1992 as part of a national study. The fish were to be removed after the study, but many persist today, according to CPW".

I got from that line that they test stocked them in a few places nationally but in CO they were not legally stocked. I see stories about these getting caught in TX and other Southern states at up to 100lbs.

I hope they got them all and no more are found. If they get into any of our major fisheries it would be a disaster.

Just out of curiosity why do you think it would be a disaster? Seems like they would compete with trout, common carp, and juvenile fish mostly. They arenít predatory. If they spawn like crazy I could see them taking up too much bio mass in a lake, but I could also see some huge walleye eating the fry. I know carp minnows are a food source for plenty of predator species. Iím by no means advocating for their widespread introduction. Just curious about the science behind why certain invasive species are worse than others. Common carp have been in most of our lakes longer than most millennials have been alive. (Millennial here)

I was shocked when I saw this news release from CPW, I've fished Birdland a handful of times over the last 15 years but never caught anything of note and deemed the water quality terrible. I'm guessing these fished thrived on the lawn runoff nutrient effects!

Looking more into the comments about the study, the NAS USGS GLER (Great Lakes Restoration) has some comments regarding Colorado and lists stocking in Larimer County water treatment ponds, several caught in Cherry Creek and stocked in Birdland Reservoir, Denver metro by the Bureau of Reclamation.

Going further, the link below lists the stocking as 500 fish in 1992 and includes the study name and information.

How they forgot these fish is incredible but looking at historical fish stocking in Colorado, 30-40 years ago it almost seemed like they tried many species in many waters to see what would stick!

<edit these are major filter feeders and will reduce all the nutrients in the water column many preferred species need to thrive - opposite of common carp working the bottom of the waterbody, uprooting plants and creating murky water looking for food, a different problem unless you like fishing mudholes>

Good info bluecollarguy! Thank you! So much for my conspiracy theories. I tried contacting Paul Winkle for some insight on this but he retired.
