Abstract The South American continent is known for its high production and exports in fisheries aquaculture, but has not reached full potential fish farming. latest data on Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Peru, Uruguay Venezuela were explored this review. Aspects of biology, production, market health the species most produced America are described detail. These include round ( Colossoma spp., Piaractus spp. hybrids) catfish Pseudoplatystoma hybrids), addition to...
Intensive fish farming systems in Brazil have increased the disease incidence, mainly of bacterial origin, due to higher stocking density, high organic matter levels and poor quality aquatic environment that causes mortality rates during outbreaks. The identification pathogenic species using a fast reliable method diagnosis is essential for successful epidemiological studies control. present study evaluated use direct colony PCR combination with 16S rRNA gene sequencing diagnose diseases,...
The effect of the essential oils (EOs) peppermint, Mentha piperita L., and tea tree, Melaleuca alternifolia (Maiden & Betche) Cheel, on haematological, biochemical, immunological parameters intestinal morphology Nile tilapia, Oreochromis niloticus was evaluated. Fish (58.09 ± 5.87 g) were fed 100 mg/kg 250 each EO sampled days 7, 14, 30 60 after starting supplementation. haematological biochemical not altered by supplementation EOs compared to control (p > .05). With regard parameters,...
Columnaris disease is one of the main causes mortality in tilapia rearing and responsible for large economic losses worldwide. Hematology a tool that makes it possible to study organisms' physiological responses pathogens. It may assist making diagnoses prognoses on diseases fish populations. The hematological variables nile were studied specimens with clinical diagnosis columnaris disease-free. total erythrocyte count, hemoglobin rate, hematocrit percentage, mean corpuscular (MCH),...
The immune system of teleost fish has mechanisms responsible for the defense against bacteria through protective proteins in several tissues. protein action can be evaluated by serum bactericidal activity and this is an important tool to analyze system. Pacu, Piaractus mesopotamicus, one most national aquaculture. However there a lack studies on its responses. In order standardize assess accuracy assay, were briefly challenged with Aeromonas hydrophila sampled week after challenge. bacterial...
Monogenean infection of the internal organs is extremely rare when compared to external infections. This study describes mass mortality Nile tilapia ( Oreochromis niloticus L.) originating from co-infection with Enterogyrus spp. and Aeromonas jandaei following transport stress. The first fish deaths occurred on day 1 post-transport, while cumulative reached approximately 90% by 10 post-stocking. An atypical amount pale (whitish) faeces floating surface water as well typical clinical signs...
Abstract In vitro effect of the Melaleuca alternifolia , Lavandula angustifolia and Mentha piperita essential oils ( EO s) against Ichthyophthirius multifiliis in vivo M. for treating ichthyophthiriasis one most important South American fish, Piaractus mesopotamicus (Holmberg), were evaluated. The test consisted three s, each at concentrations 57 μL L −1 114 227 455 which assessed once an hour 4 h microtitre plates (96 wells). results demonstrated that all tested s showed a cytotoxic I....
SUMMARY Prochilodus lineatus is a freshwater fish species found in South America. It common aquaculture, but few studies regarding diseases of this have been performed. This study presents data the occurrence Trichodina heterodentata Duncan, 1977, as well pathological alterations detected by light and scanning electron microscopy (SEM). Twenty 20-day-old larvae were harvested from an earth pond examined. Larvae showed erratic swimming on edges some had whitish tegument. Larval smears either...
Trichodinids are ciliated protozoa that widely known as one of the main groups fish parasites. The genus Trichodina presents greatest species diversity. However, records Paratrichodina scarce, and little is about their pathogenicity in hosts. present study provides new africana Kazubski El-Tantawy (1986) Nile tilapia from South America descriptions pathological changes seasonality. A total 304 farmed were examined. From gill scraping, parasites identified using Klein's nitrate impregnation...
Chilodonelids are small ciliated protozoans found worldwide and can be dangerous in culture conditions. This study presents morphometric data on the ciliate Chilodonella that is cultured Nile tilapia (Oreochromis niloticus), native bait fish tuvira (Gymnotus aff. inaequilabiatus) pacu (Piaractus mesopotamicus) includes a histopathological assessment of changes occur pacu. For parasitic diagnosis, skin gill samples were scraped onto slides, dried at room temperature, stained with Giemsa or...
