Time‐calibrated relationships of a rare cave catfish (Trichomycterus rubbioli): Shedding light on troglobitic lifestyle origin in the Brazilian caatinga

Journal of Fish Biology, EarlyView.
Abstract Catfishes of the subfamily Trichomycterinae comprise the most diverse fish group with species adapted to live in Neotropical caves, but past evolutionary scenarios that have driven the origin of these troglobitic species remain unknown. We herein investigate the phylogenetic position of the cave‐restricted Trichomycterus rubbioli, endemic to ...

Isolated in the highlands, found in the museum: A new species of Characidium (Crenuchidae) from a Bolivian National Park, with a CT scan revealing features

Journal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from a small, isolated river in the highland areas of Noel Kempff Mercado National Park, Bolivia. The new taxon can be diagnosed by the presence of a relatively broad and conspicuous dark midlateral stripe extending from the tip of snout to the base of the caudal fin, markedly darker than the vertical ...

Miocene catfishes (Ariidae,Bagridae) from Lisbon: a Nilotic (or Sudanian) type fauna [PDF]

, 2010
Miocene catfishes from Lisbon are dealt with. Two distinct sets of pectoral and dorsal pterygiophores are described. That from the Langhian V-b is referred to Arius sp. probably close to A. heudeloti. Another ser from the uppermost Burdigalian V-a may be

A new species of inseminating catfish of the genus Tympanopleura (Siluriformes: Auchenipteridae) from the Ituxi River, Amazon River basin, northern Brazil, revealed by integrative taxonomy

Journal of Fish Biology, EarlyView.
Abstract A new species of the genus Tympanopleura is described from the Iquiri River, a tributary of the Ituxi River, a right‐bank tributary to the Purus River, Amazon River, northern Brazil. The new species is distinguished from all its congeners by a combination of features, such as the presence of an intensely pigmented square‐shaped blotch on the ...

Haematological and histopathological monitoring of monosodium glutamate–supplemented feeding in rainbow trout (Oncorhynchus mykiss): A possible modelling for a single health approach

Journal of Fish Biology, EarlyView.
Abstract The aim of this study was to investigate the potential effects of monosodium glutamate (MSG), a known flavour enhancer added to many ready‐to‐eat foods, as a feed additive in rainbow trout (Oncorhynchus mykiss). Evaluating the effects of MSG on aquatic organisms will fill the knowledge gap in this field by monitoring the haematological indices

Mitochondrial 16S rRNA sequence variations and phylogeny of the Chinese sisorid catfishes

, 2004
Partial sequences of mitochondrial 16S rRNA gene were obtained by PCR amplification for comparisons among nine species of glyptosternoid fishes and six species of non-glyptosternoids representing 10 sisorid genera. There are compositional biases in the A-

Chronic thermal stress affects growth, liver morphology and molecular responses but allows recovery at optimal temperature in juvenile zebrafish (Danio rerio)

Journal of Fish Biology, EarlyView.
Abstract Climate‐driven aquatic heatwaves pose an increasing threat to fish populations by inducing prolonged thermal stress. However, the resilience of teleosts to chronic heat exposure and their capacity for recovery remains poorly understood. This study investigated the effects of chronic high‐temperature exposure on juvenile zebrafish (Danio rerio).

Paracamallanus cyathopharynx (Baylis, 1923) Infection in Clarias gariepinus (Burchell, 1822): Linking the Morphology of Wound‐Inflicting Structures to Histopathology

Journal of Fish Diseases, EarlyView.
ABSTRACT Paracamallanus cyathopharynx (Baylis, 1923) specimens were collected from the rectum of the African sharptooth catfish, Clarias gariepinus in Lake Heritage, Crocodile River in the Limpopo River system and in the Vaal River below the Vaal Dam. Attached and unattached parasites were studied with light and scanning electron microscopy along with ...
