  • Year of the Catfish with the Intention of Writing an Article Relating to Some Aspect of Catfish in the Aquarium on a Monthly Basis
    YYeeaarr ooff tthhee CCaattffiisshh A monthly column about Catfish Talking... (Doradidae) by Derek Tustin (Author’s Note: I started The Year of the Catfish with the intention of writing an article relating to some aspect of Catfish in the aquarium on a monthly basis. Last month, April 2013, I did not. I know this caused a bit of consternation on the part of Klaus Steinhaus, the editor of Tank Talk, and he had to find another article to fill the space. As such, I offer both he and the readers of Tank Talk my sincere apologies and to make up for it, give you a double helping of The Year of the Catfish this month. – Derek P.S. Tustin) o you have that one fish species of fish that you have Agamyxis pectinifrons D an unbridled affinity for? That one special species that just strikes a chord with you that you want to keep no matter what? Perhaps something that you have kept every time the opportunity presents? I think we all have a small group of species that no matter how unattractive other aquarists may find them, we want to keep them. I think you all know by now my absolute fascination with rainbowfish, and the extent that I am willing to go to obtain certain species. Given that, you might be surprised to know that my “soft-spot species” isn’t a rainbowfish, but rather a catfish, specifically the White-Spotted Doradid, Agamyxis pectinifrons. (Or it actually might be… but I’ll get to that in a bit.) Agamyxis pectinifrons is a member of the Doradidae family.

  • 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.

  • Phylogenetic Relationships of the South American Doradoidea (Ostariophysi: Siluriformes)
    Neotropical Ichthyology, 12(3): 451-564, 2014 Copyright © 2014 Sociedade Brasileira de Ictiologia DOI: 10.1590/1982-0224-20120027 Phylogenetic relationships of the South American Doradoidea (Ostariophysi: Siluriformes) José L. O. Birindelli A phylogenetic analysis based on 311 morphological characters is presented for most species of the Doradidae, all genera of the Auchenipteridae, and representatives of 16 other catfish families. The hypothesis that was derived from the six most parsimonious trees support the monophyly of the South American Doradoidea (Doradidae plus Auchenipteridae), as well as the monophyly of the clade Doradoidea plus the African Mochokidae. In addition, the clade with Sisoroidea plus Aspredinidae was considered sister to Doradoidea plus Mochokidae. Within the Auchenipteridae, the results support the monophyly of the Centromochlinae and Auchenipterinae. The latter is composed of Tocantinsia, and four monophyletic units, two small with Asterophysus and Liosomadoras, and Pseudotatia and Pseudauchenipterus, respectively, and two large ones with the remaining genera. Within the Doradidae, parsimony analysis recovered Wertheimeria as sister to Kalyptodoras, composing a clade sister to all remaining doradids, which include Franciscodoras and two monophyletic groups: Astrodoradinae (plus Acanthodoras and Agamyxis) and Doradinae (new arrangement). Wertheimerinae, new subfamily, is described for Kalyptodoras and Wertheimeria. Doradinae is corroborated as monophyletic and composed of four groups, one including Centrochir and Platydoras, the other with the large-size species of doradids (except Oxydoras), another with Orinocodoras, Rhinodoras, and Rhynchodoras, and another with Oxydoras plus all the fimbriate-barbel doradids. Based on the results, the species of Opsodoras are included in Hemidoras; and Tenellus, new genus, is described to include Nemadoras trimaculatus, N.

Wong Abstract Two North American species of mosquitofish, the Western (Gambusia affinis Baird and Girard, 1853) and Eastern mosquitofish (G. holbrooki Girard, 1859), rank amongst the most invasive freshwater fishes worldwide. While the existing literature suggests that G. affinis was introduced to mainland China, empirical evidence supporting this assumption was limited, and the possibility remained that both species were introduced during campaigns attempting to reduce vectors of malaria and dengue fever. We used combined molecular information (based on phylogenetic analyses of sequence variation of the mitochondrial cytochrome b gene) and morphometric data (dorsal and anal fin ray counts) to confirm the presence

  • Status and Critical Habitat of Rare Fish Species in the Mississippi River from the Coon Rapids Dam to the Iowa Border
    State Wildlife Grant Final Report Status and critical habitat of rare fish species in the Mississippi River from the Coon Rapids Dam to the Iowa border Konrad Schmidt (Nongame Fish Program) Nick Proulx (Bio-criteria Development Program) Minnesota Department of Natural Resources Division of Ecological Resources 9 March 2009 Paddlefish (Polyodon spathula) from Lake Pepin Abstract From 2006 through 2008, the Mississippi River was surveyed from the Coon Rapids Dam (Pool A) to the Iowa border (Pool 9). Sampling gear consisted of boat and backpack electroshockers, gill nets, trap nets, trawls, seines, dip nets and setlines. Habitats included main and side channels, backwaters, tributary mouths and tailwater zones of dams. The three year study found 16 of 22 Species in the Greatest Conservation Need (SGCN) reported from the Minnesota reach of the Mississippi River. Introduction The study area covers 192 river miles and includes 12 pools impounded by locks and dams that were originally designed for commercial navigation, but this corridor has become extremely popular with recreational watercraft users. The US Army Corps of Engineers maintains the navigation channel of the pools at a minimum depth of nine feet. Prior to the lock and dam system, thousands of closing and wing dams were constructed during the late 1800s. The closing dams reduced flow to backwaters and side channels, while wing dams directed current down the main channel to maintain navigable depths. These structures are not maintained, but most remain and continue to function. The long-term results of this altered flow regime has filled in many side channels and backwaters with sediments or greatly reduced their depth and size.
