The proximate composition and fatty acid (FA) profiles of five Brazilian freshwater fish species, namely Brycon cephalus (BC), Cichla ocellaris (CO), Prochilodus lineatus (PL), Leporinus friderici (LF) and Pseudoplatystoma corruscans (PCO), were investigated. CO and LF exhibited the highest (p < 0.05) moisture content, as well as one of the lowest (p < 0.05) lipid values, whereas BC presented t...

Two species of mayfly nymphs, Habroleptoides modesta (Hagen) and Habrophlebia lauta (Eaton) (Ephemeroptera: Leptophlebiidae), were found as suitable experimental intermediate hosts of the fish nematode Rhabdochona denudata (Dujardin, 1845) (Rhabdochonidae), an intestinal parasite of Palaearctic cyprinids. The parasite's eggs were obtained from nematode gravid females parasitizing the European c...

Desert fishes are some of the most imperiled vertebrates worldwide due to their low economic worth and because they compete with humans for water. An ecological complex of fishes, 2 suckers (Catostomus latipinnis, Catostomus discobolus) and a chub (Gila robusta) (collectively managed as the so-called three species) are endemic to the U.S. Colorado River Basin, are affected by multiple stressors...

During the present investigation, 23 species of fish in Lithuanian inner waters were examined for helminth parasites. Of these, 63 taxa helminths – 56 Plathyhelminthes, five Nematoda, and two Acanthocephales found. Monogenea Gyrodactylus truttae was registered Lithuania first time. Metacercariae flukes Diplostomum sp., Posthodiplostomum cuticula, Tylodelphys clavata found highest number host sp...

To assess if they were within the safety limits for human consumption, the Cd, Cu, Pb, and Zn contents of fish muscles, bought from separate stalls of the fish markets of nine cities of NW Mexico, were determined by atomic absorption spectrophotometry. Considering all fish and markets, the mean contents were Zn: 23.23 ± 5.83, Cu: 1.72 ± 0.63, Cd: 0.27 ± 0.07, and Pb: 0.09 ± 0.04 µg/g (dry weigh...

The monogenean Ligophorus chabaudi was originally described on the gills of the flathead mullet, Mugil cephalus, and was subsequently reported on the So-iuy mullet, Mugil soiuy. However, the morphology of sclerotized parts and multivariate statistical analyses suggest that the form from the So-iuy mullet represents a new species. This study provides a description of the new species Ligophorus p...

OBJECTIVE To develop a minimally invasive intraoral technique to transfer the submandibular gland into the submental space. STUDY DESIGN Experimental cadaver study. METHODS Five cephalus specimen, a total of 10 submandibular glands, underwent this intraoral approach. Primary outcome measures included operative time, length of gland transfer, adequate ligation of facial vessels, and preserva...
