The aim of this research was to study the gastrointestinal parasitism in 12 adult owls kept in captivity in the Southern region of Brazil. Cloacal contents of the species Rhinoptynx clamator, Tyto alba, Athene cunicularia, Megascops spp., and Bubo virginianus were evaluated. Feces and urine were collected and analyzed by the zinc sulfate(More)
The anthelmintic activity of the eugenol against the fish parasite Gyrodactylus sp. was evaluated. After 1-h exposure to 5 and 10 mg/L eugenol, mortality of the parasites was near 80 and 90%, respectively. The concentrations used in the antiparasitic test were not toxic to Daphnia pulex (LC50 42.5 mg/L).
Rhamdia quelen morphophysiological responses to propofol sedation were examined. The purpose was to investigate whether propofol would be a suitable drug to be used in fish transport procedures. Fish were exposed to 0, 0.4 or 0.8 mg L−1 propofol for 1, 6 or 12 h in 40 L tanks, simulating open transport systems. Propofol was able to prevent the peak of(More)
Imazapyr (IMY) and imazapic (IMI) are imidazolinone herbicides which have been associated in a commercial formulation (Kifix(®)). To date, there are no studies on the toxicity of an IMY+IMI herbicide in fish. This work aimed to assess the acute toxicity (24 and 96 h) of IMY+IMI (0, 0.488 and 4.88 µg/L) towards Rhamdia quelen through hematological,(More)
The effects of adding rutin to the diet (0, 0.15 or 0.30 %) of silver catfish for 21 days on blood parameters, oxidative stress biomarkers and pituitary hormones expression were investigated. Fish that received the diet containing 0.15 % rutin exhibited reduced plasma cortisol levels. The levels of lipid peroxidation were lowered in the all tissues of(More)
Aquatic animals are naturally exposed simultaneously to environments with different concentrations of humic acid (HA) and seasonal or daily variations of dissolved oxygen (DO) levels. This study investigated the effects of simultaneous exposure to different HA and DO levels on plasma ion levels and some hematological and oxidative parameters in different(More)
OBJECTIVE To investigate the effects of rapid anesthesia and long-term sedation with the essential oils (EOs) of Myrcia sylvatica (EOMS) and Curcuma longa (EOCL) on biochemical and oxidative parameters in matrinxã. STUDY DESIGN Prospective, randomized, laboratory experiment. ANIMALS A total of 72 matrinxã (Brycon amazonicus) adults weighing 404.8 ± 27.9(More)
