  • 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.

  • The Microhabitat, Behavior and Diet of Centromochlus Meridionalis, a Small Catfish of Amazon Streams (Teleostei: Auchenipteridae)
    221 Ichthyol. Explor. Freshwaters, Vol. 26, No. 3, pp. 221-228, 2 figs., 2 tabs., November 2015 © 2015 by Verlag Dr. Friedrich Pfeil, München, Germany – ISSN 0936-9902 The microhabitat, behavior and diet of Centromochlus meridionalis, a small catfish of Amazon streams (Teleostei: Auchenipteridae) Fernando Gonçalves Cabeceira*, Denise Caragnato Parisotto**, Jansen Zuanon***, Alberto Akama**** and Lucélia Nobre Carvalho*, ** Centromochlus meridionalis was recently described from streams of Brazilian Amazon. The marbled dark brown and black color pattern together with the use of submersed leaf litter accumulations for shelter differentiates this species among its congeners. We present information about the biology of C. meridionalis based on data gathered in streams and under captivity, as well as on a dietary analysis. Behavioral observations were made in captivity (aquaria). Dietary analysis was performed based on stomach contents of 38 specimens. The species was found in 8 out of 12 small streams sampled, where specimens were captured predominantly amidst submerged leaf litter. Nine types of behavioral acts were identified, of which “swimming near the substratum” and “charging the substratum for food” were the most frequent. Thirty (~ 79 %) out of the 38 stomachs had food, and the diet was composed of 27 types of food items. Centromochlus meridionalis can be considered a generalist microcarnivore, consuming predominantly authochtonous and allochtonous insects, and other terrestrial invertebrates, crustaceans and fish as well. The use of different water column strata during foraging and the diversity of food items consumed indicate that this small catfish utilizes several feeding tactics.

Of the 48 species previously considered valid in the subfamily, only one, Centromochlus steindachneri, was not evaluated in the present study. The phylogenetic analysis generated two most parsimonious trees, each with 202 steps, that support the monophyly of Centromochlinae composed of five valid genera: Glanidium, Gephyromochlus, Gelanoglanis, Centromochlus and Tatia. Although those five genera form a clade sister to the monotypic Pseudotatia, we exclude Pseudotatia from Centromochlinae. The parsimony analysis placed Glanidium (six species) as the sister group to all other species of Centromochlinae. Gephyromochlus contained a single species, Gephyromochlus leopardus, that is sister to the clade Gelanoglanis (five species) + Centromochlus (eight species).

  • Structure of Tropical River Food Webs Revealed by Stable Isotope Ratios
    OIKOS 96: 46–55, 2002 Structure of tropical river food webs revealed by stable isotope ratios David B. Jepsen and Kirk O. Winemiller Jepsen, D. B. and Winemiller, K. O. 2002. Structure of tropical river food webs revealed by stable isotope ratios. – Oikos 96: 46–55. Fish assemblages in tropical river food webs are characterized by high taxonomic diversity, diverse foraging modes, omnivory, and an abundance of detritivores. Feeding links are complex and modified by hydrologic seasonality and system productivity. These properties make it difficult to generalize about feeding relation- ships and to identify dominant linkages of energy flow. We analyzed the stable carbon and nitrogen isotope ratios of 276 fishes and other food web components living in four Venezuelan rivers that differed in basal food resources to determine 1) whether fish trophic guilds integrated food resources in a predictable fashion, thereby providing similar trophic resolution as individual species, 2) whether food chain length differed with system productivity, and 3) how omnivory and detritivory influenced trophic structure within these food webs. Fishes were grouped into four trophic guilds (herbivores, detritivores/algivores, omnivores, piscivores) based on literature reports and external morphological characteristics. Results of discriminant function analyses showed that isotope data were effective at reclassifying individual fish into their pre-identified trophic category. Nutrient-poor, black-water rivers showed greater compartmentalization in isotope values than more productive rivers, leading to greater reclassification success. In three out of four food webs, omnivores were more often misclassified than other trophic groups, reflecting the diverse food sources they assimilated. When fish d15N values were used to estimate species position in the trophic hierarchy, top piscivores in nutrient-poor rivers had higher trophic positions than those in more productive rivers.

  • 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.
