Abstract The aim of this study was to characterise possible histopathological and haemato-immunological changes after subclinical infection by S. agalactiae S13 serotype Ib. One hundred juveniles of Nile tilapia with average weight of 45 g were distributed in ten 90 L experimental units. After the acclimation period 25 fish were euthanised, and fragments of liver, spleen and posterior mid-intestine tissue were sampled to verify the integrity of the organs and blood samples taken to check the hae...

Nile tilapia is an exotic species produced in Brazilian aquaculture. The aim of this study was to constitute a pathological diagnosis in Oreochromis sp. with a noticeable presence in a river in southern Brazil, and to verify the origin of these fish in this natural habitat, an environment with high sanitary precariousness due to discharges of industrial effluents. A total of 30 fish were collected during three sampling events and their health status was assessed by parasitological fauna survey, ...

This study evaluated the effects of dietary supplementation of organic acids blend (OAB) alone or in combination with essential oil, Lippia origanoides (OAE) for Nile tilapia fed supplemented diets for 30 days. Fish (1.1 ± 0.04 g) were fed control (Control), or OAB 0.5% or OAB 0.5% + essential oil 0.125% (OAE) respectively. At the end of the experiment, samples were collected for de hemato‐immunological, histological analysis of the intestine and liver, as well as microbiology of the intestine. ...

Abstract Essential oils are obtained from vegetal material and present antibacterial activities, antioxidant, antiviral, antifungal properties and may replace the use of chemotherapeutics for treating and prophylaxis in fish farm. The objective of this study was to verify the influence of essential oil of Mentha piperita in the prevention of Streptococcus in Nile tilapia. A total of 300 fish with approximately 5 g were divided into 20 tanks with 15 fish each were fed diet supplemented with essen...

Abstract Food additives based on organic acids or their salts promote numerous improvements in zootechnical parameters, digestive enzymatic activities, resistance to diseases and intestinal health. This study aimed to evaluate the influence of calcium and sodium chelated to propionic acid on the digestive enzymes activities, intestinal microbial community and histological alterations in the liver and intestine of the silver catfish Rhamdia quelen. Fish with an initial mean weight of 8.43 ± 0.18 ...

This work evaluated the effects of dietary supplementation of A-Live (phytogenic) either individually or in combination with Aquaform (potassium diformate, acidifier) on juvenile Nile tilapia (Oreochromis niloticus) growth performance, innate immune parameters, gut microbiome, and resistance against Francisella noatunensis subsp. orientalis challenge. Each experimental group contained 140 fishes (34.3 ± 0.33) in two 150L tanks. The experimental design consisted of five groups: a negative control...

Abstract The aim of the present study was to verify the effect of sodium butyrate in protected and unprotected forms at two different concentrations of diet inclusion (0.25% or 0.5%) on the digestive enzyme's activity, integrity and structure of the intestinal tract and liver, in juveniles of Oreochromis niloticus, during the period of sexual reversion. In the experimental period, 3150 newly hatched post-larvae were randomly distributed in 21 experimental units of 100 L, divided into six treatme...

Fish may bioaccumulate contaminants from the aquatic environment and extend them to the food chain provoking risks to human health. This study evaluated the microbiological parameters of the pond´s water and trace elements concentrations in samples of water, sediment, feed and muscle of farmed Nile tilapia used for human consumption in southern Brazil. A total of 240 fish were collected from 12 tilapia farms. Sediment, tank water and dry ration used in the animals' diet were collected for analys...

Abstract This study evaluated the use of biopromoter Gamaxine for fish, a product elaborated from the fermentation of purified cultures of inactivated saprophytic bacteria, at the original concentration of 1.0 g L −1 , to favor the equilibrium of the intestinal microbiota, providing better protection against the enteric challenges. It is used originally as against enteric challenges and consequently improving the productive performance of poultry. The biopromoter was manufactured by Vetanco comp...
