5% of US Freshwater Fish Species Petitioned for Endangered or Threatened Status

Watersheds with 10 or more at-risk fish and mussel species are concentrated in the Southeast,
reflecting the extraordinary species diversity of rivers and streams in this region.  (Rivers of Life)


The dynamic physiographic provinces spanning the Southeastern United States, comprised of mountains, piedmont, and coastal plains, combined with the historic absence of ice sheets and glaciers, created incredibly diverse aquatic ecosystems and species.  Altered and fragmented habitats, invasive species, overharvest, disease, and pollution are threatening that diversity, putting aquatic ecosystems at risk.

A petition to the United States Fish and Wildlife Service (USFWS) was made by The Center of Biological Diversity in April of 2010 to list 404 aquatic, riparian, and wetland species from the Southeastern United States as threatened or endangered under the Endangered Species Act.  This petition was a result of a 1994 USFWS request favoring multi-species listings that are appropriate when several species have common threats, habitat, distribution, landowners, or features that would group the species and provide more efficient listing and subsequent recovery.

In September 2011, the USFWS found that protection of 374 of the 404 may be warranted and will conduct an in-depth status review of each species.  Eighteen of the remaining 30 species were already listed as candidates for protection, and the final 12 species were fish that did not have substantial scientific or commercial information to move forward.

The 374 species being considered include 89 species of crayfish and other crustaceans, 81 plants, 78 mollusks, 51 insects, 43 fish, 13 amphibians, 12 reptiles, 4 mammals and 3 birds, and are found in 12 states: Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Virginia and West Virginia.With just over 800 described freshwater fish species in the United States, the 43 included fish species represent 5% of that total, indicating the strong implications of this petition and review for fisheries research.  Yet, the Association for Biodiversity further suggests an additional 250 freshwater fish species at risk, demonstrating the need for further attention in other regions.

Those in the scientific community with expertise concerning the status of a species under review are asked to submit information in regards to:
The species’ biology, range, and population trends, including:
(a) Habitat requirements for feeding, breeding, and sheltering;
(b) Genetics and taxonomy;
(c) Historical and current range, including distribution patterns;
(d) Historical and current population levels, and current and projected trends;
(e) Past and ongoing conservation measures for the species, its habitat, or both.

    You said you never had comments; that sounded like a challenge to me. Point 1: Patrick should really spellcheck his titles. ;-P Point 2: Which is actually relevant. It is important to note that aside from an intial 90-day review, NONE of these species will be able to be addressed by USWFS staff until they deal with another 204-ish species that WildEarth Guardians sued over – a settlement was reached and those 200-ish species, languishing in candidate status, must be dealt with over the next six years.

    As a result, the species in this petition will not see any action until AT LEAST 2018 and some will not be appropriate for listing at all. A lot can change in six years.

    The information provided by “eventer79” demonstrates an even greater need to make sure those that have information about these species continue to monitor the population/populations over time. While more evaluation time may not be good in terms of possible habitat losses and further declines in numbers of individuals, it will give a better view into the trends to make sure that better informed decisions are made (hopefully minimizing the possibility for future legal disputes).

  4. Hi,

    Recently I came across some great articles on your site. The other day, I was discussing ( http://thefisheriesblog.blogspot.in/2012/02/5-of-us-freshwater-fish-species.html) with my colleagues and they suggested I submit an article of my own. Your site is just perfect for what I have written! Would it be ok to submit the article? It is free of charge, of course!

    What you published was very reasonable. But, think on this,
    suppose you composed a catchier post title? I ain’t suggesting your

    get folk’s attention? I mean 5% of US Freshwater Fish Species Petitioned for Endangered or Threatened Status | The Fisheries
    Blog is kinda plain. You might peek at Yahoo’s home page and watch how they create post titles to grab viewers interested.

    You might add a related video or a picture or two to
    grab people interested about what you’ve written. In my opinion, it could
    make your blog a little livelier.
