Important data on how the humpback chub was able to survive in the Colorado River Basin for the last 3 to 5 million years will be used to develop Colorado River water allocation policy in the future. The U.S. Fish and Wildlife Service is currently proposing to downlist the humpback chub from endangered to threatened. http://ow.ly/Otfl50AJc7V

Raising super walleye

Garrison Dam National Fish Hatchery in North Dakota are raising “super” walleye that will be introduced to the non-native population of walleye in Idaho in order to decrease the number of walleye that are consuming their cutthroat trout. http://ow.ly/dLnC50AJ5ae

RIVERDALE – They are raising “super” walleyes at the Garrison Dam National Fish Hatchery. No. It’s not quite what you might imagine. These will not be gigantic fish that will overtake the record book or swallow up boats and anglers. Quite the opposite. These super walleyes will be used to he...

What do you get when you cross a sturgeon and a paddlefish? Well, a sturddlefish of course! This occurred when a Russian sturgeon successfully hybridized with an American paddlefish for the first time in captivity. Believe it or not! http://ow.ly/qa7u50AHyCu

Scientists accidentally created a "sturddlefish," or hybrid of an American paddlefish and a Russian sturgeon, in an attempt to help the critically endangered sturgeon reproduce asexually. Instead, they wound up with a new fish entirely.

It is FWCO Friday! After sampling over 2,200 sites from 1996-2018 and employing ten different gear types, the Alpena Fish and Wildlife Conservation Office, including the Detroit River substation, Aquatic Invasive Species Program, was able to add Four New Native Fish Species to list in 2019. These are species that had not been previously observed in the survey. New program species included the river redhorse, grass pickerel, lake sturgeon, and warmouth. These exciting results were likely a due to several factors. First, overall fishing effort was increased in 2019. Second, the survey design was changed from a random exploratory survey to one that used past years information to guide gear deployment in fishing “hot spots”. Third, 12 new sampling locations were added to the survey. Both the grass pickerel and warmouth were detected in two of these new locations. http://ow.ly/jp5150AHap4

A good year for an Aquatic Invasive Species (AIS) program is when we detect NOTHING new. That’s right, it is a program where finding nothing is a good thing! Alpena Fish and Wildlife Conservation Office and Detroit River Substation search for newly introduced invasive or non-native species annually. 2019 was a Good a year, where no new AIS were captured during sampling in Lake Erie and Lake Huron. It is anticipated that new improvements to the AIS program will continue into the future and help with the early detection of non-native species, a key to protecting the Great Lakes ecosystem. Hopefully we will continue to catch “nothing”. http://ow.ly/u4bF50AH8w9

This is yet another example of how our Fish and Wildlife Conservation Offices work with partners to monitor and assess the status of our native species so that adaptive management strategies can be developed and implemented to help insure their sustainability over the long term. Now that is real Teamwork! 👍

The Pueblo, with help from the New Mexico Fish and Wildlife Conservation Office, has once again completed its summer fish community monitoring. It seems that every year is unique, but this year was especially unusual, both for fish and people. With PPE and social distancing measures in place, the team went into the river properly spaced apart and protected. We caught fish in almost each of the 120 seine hauls. Most were common, like red shiners and white suckers, but some were more rare this year including the Rio Grande silvery minnow. We caught large fish, such as catfish, that we usually catch as small fish and small fish, like small and large mouth bass, that we usually catch as larger fish. We had a very productive monitoring event and couldn’t have done it without the assistance from the folks at New Mexico Fish and Wildlife Conservation Office.
