Introductions of Threatened and Endangered Fishes (Full Statement)
AFS Policy Statement #19: Introductions of Threatened and Endangered Fishes (Full Statement) ABSTRACT Introductions of threatened and endangered fishes are often an integral feature in their recovery programs. More than 80% of threatened and endangered fishes have recovery plans that call for introductions to establish a new population or an educational exhibit, supplement an existing population, or begin artificial propagation. Despite a large number of recent and proposed introductions, no systematic procedural policies have been developed to conduct these recovery efforts. Some introductions have been inadequately planned or poorly implemented. As a result, introductions of some rare fishes have been successful, whereas recovery for others has progressed slowly. In at least one instance, the introduced fish eliminated a population of another rare native organism. We present guidelines for introductions of endangered and threatened fishes that are intended to apply when an introduction is proposed to supplement an existing population or establish a new population. However, portions of the guidelines may be helpful in other Situations, such as establishing a hatchery stock. The guidelines are divided into three components: (1) selecting the introduction site, (2) conducting the introduction, and (3) post-introduction monitoring, reporting, and analysis. Implementation should increase success of efforts to recover rare fishes. "On 3 August 1968, we collected 30 or 40 individuals from among the inundated prickly pear and mesquite near the flooded spring, which by that time was covered with about 7 m of clear water." Peden (1973) The above quote described the collection of Amistad gambusia, Gambusia amistadensis, as its habitat was being flooded. Fortunately, most translocations of endangered fishes do not occur under such a feverish pace as did this collection of Amistad gambusia. -
Endangered Species
FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

Resolving Cypriniformes Relationships Using an Anchored Enrichment Approach Carla C
Stout et al. BMC Evolutionary Biology (2016) 16:244 DOI 10.1186/s12862-016-0819-5 RESEARCH ARTICLE Open Access Resolving Cypriniformes relationships using an anchored enrichment approach Carla C. Stout1*†, Milton Tan1†, Alan R. Lemmon2, Emily Moriarty Lemmon3 and Jonathan W. Armbruster1 Abstract Background: Cypriniformes (minnows, carps, loaches, and suckers) is the largest group of freshwater fishes in the world (~4300 described species). Despite much attention, previous attempts to elucidate relationships using molecular and morphological characters have been incongruent. In this study we present the first phylogenomic analysis using anchored hybrid enrichment for 172 taxa to represent the order (plus three out-group taxa), which is the largest dataset for the order to date (219 loci, 315,288 bp, average locus length of 1011 bp). Results: Concatenation analysis establishes a robust tree with 97 % of nodes at 100 % bootstrap support. Species tree analysis was highly congruent with the concatenation analysis with only two major differences: monophyly of Cobitoidei and placement of Danionidae. Conclusions: Most major clades obtained in prior molecular studies were validated as monophyletic, and we provide robust resolution for the relationships among these clades for the first time. These relationships can be used as a framework for addressing a variety of evolutionary questions (e.g. phylogeography, polyploidization, diversification, trait evolution, comparative genomics) for which Cypriniformes is ideally suited.

Articles Extinction Rates in North American Freshwater Fishes, 1900–2010 NOEL M. BURKHEAD Widespread evidence shows that the modern rates of extinction in many plants and animals exceed background rates in the fossil record. In the present article, I investigate this issue with regard to North American freshwater fishes. From 1898 to 2006, 57 taxa became extinct, and three distinct populations were extirpated from the continent. Since 1989, the numbers of extinct North American fishes have increased by 25%. From the end of the nineteenth century to the present, modern extinctions varied by decade but significantly increased after 1950 (post-1950s mean = 7.5 extinct taxa per decade). -

And this was suggested as one of the earliest records for fossil cyprinids. Unfortunately, this specimen is poorly preserved and reveals no more morphological information than its serrated last unbranched dorsal and anal fin rays. Recently, some new specimens were unearthed from the same locality, where C. maomingensis was discovered. In addition to the serrated dorsal and anal fin rays, these new materials also show that the pattern and shape of their pharyngeal teeth obviously differ from that of Cyprinus but resemble that of Procypris. However, its number of the branched dorsal fin rays and number of vertebrae are much less than that in Procypris. -

It differs from all other cyprinid fishes in the following character combination: tooth formula —3·2·1, crushing molar-like A1 much larger than A2, only one groove on the grinding surface of A2 and B1 respectively, and the anterior angle of the pharyngeal bone triangular and prominent. The new-found Cyprinus-like fish, along with the previously known Late Eocene †Eoprocypris maomingensis (Procypris-like) and Oligocene †Huashancyprinus robustispinus (Cyprinus-like) from South China, further indicates an early branching and diversification of the Cyprininae (Cyprinidae) in this area.

Point or condition when species will be considered for deListing: The Big Bend gambusia may never be downlisted or delisted because of its extremely limited distribution and tenuous habitat conditions. Downlisting the species to threatened classification could be considered if all recovery actions, as proposed in this Recovery Plan, are implemented. 2. What must be done to reach recovery: Steps to reach recovery include maintaining and enhancing habitats where Big Bend gambusia presently exist and establishing populations in other suitable locations. To insure against loss of the species a captive population must be maintained until survival of several populations in the wild are assured. 3. Management needs to keep the species recovered: To keep the species recovered it will be necessary to monitor populations to insure they are viable and the habitats are being managed to maintain the species. DISCLAIMER This is the completed Big Bend Gambusia Recovery Plan. It has been approved by the U.S. Fish and Wildlife Service. It dces not necessarily represent official positions or approvals of cooperating agencies and it does not necessarily represent the views of all recovery team members/ individuals, who played the key role in preparing the plan. -
