The aim of this paper was to describe the distribution of non-specific immune parameters in two fish species considered as new candidates for aquaculture diversification, greater amberjack and blackspot seabream. In particular, haemolysins, haemagglutinins and lysozyme were investigated to monitor their changes induced by two different stressors: 1) an experimental challenge of greater amberjac...
The presence of Aeromonas salrnonicida, the etiological agent of furunculosis, was examined using polymerase chain reaction (PCR) and DNA probe methodology in wild Atlantic salmon Salmo salar taken from 3 Irish river systems Blood samples from 61 individual fish were examined and the presence of pathogen was determined in 87% of the fish examined. However, the level of pathogen was extremely lo...
—Many effects of diseases on cultured fish are known; they are less clear in wild fish populations. Cultured fish represent captive populations that can be subjected to intense scrutiny with an increasing range of diverse and powerful tools. Disease represents a spectrum from acute mortality to rather benign or inconsequential syndromes, all sharing the common feature of a deviation from the no...
Flavobacterium columnare is a Gram-negative, rod-shaped, motile, and highly prevalent fish pathogen causing columnaris disease in freshwater fish worldwide. Here, we present the complete genome sequence of F. columnare strain ATCC 49512.
A study was carried out from October, 2009 to April, 2010 with the objective of isolating Edwardsiella tarda an important fish pathogen from fish harvested for human consumption from Lake Zeway and Langanoo. A total of 372 tissue samples (three from each fish) comprising liver, intestine and kidney were collected from 124 fish (Clarias gariepinus and Oreochromis niloticus originated from Lake L...
One of the main challenges in aquaponics is disease control. One possible solution for this is biological control with organisms exerting inhibitory effects on fish and plant pathogens. The aim of this study was to examine the potential of isolating microorganisms that exert an inhibitory effect on both plant and fish pathogens from an established aquaponic system. We obtained 924 isolates on s...
