“…from freshwater red tilapia. In our previous study, we have detected multiple antibiotic resistance of diverse Aeromonas strains from various ornamental fish such as guppy and koi carp (Preena, Dharmarathnam, Raj, Kumar, Raja, Nair et al, 2019; Preena, Dharmarathnam, Raj, Kumar, Raja, & Swaminathan, 2019). The possible threat of virulent and antibiotic‐resistant motile aeromonads in ornamental fish culture systems to public health was also investigated by Sreedharan, Philip, and Singh (2012).…”

Aquaculture sector is in continuous progress throughout the world to meet the global fish food demand. In the earlier period onwards, tilapia cultivation gained more attention globally, next to carps, and more than 100 countries have selected tilapia as the candidate fish for aquaculture (Raj et al., 2019). Among them, Nile tilapia, Oreochromis niloticus, plays a major role in global production of tilapia by holding sixth position (Reantaso, 2017). Nile tilapia is one of the major fish species, which are more prone to aeromonad infections (Baumgartner, Ford, & Hanson, 2017). Disease outbreak due to aeromonads is frequent in farmed fish worldwide, and hence, the magnitude of infections and the characteristics of aetiological agents need to be analysed in detail (Mzula, Wambura, Mdegela, & Shirima, 2019). A wide range of diseases were reported in cultured fish due to different species of Aeromonas; mainly, A. hydrophila, A. veronii and A. caviae (Lewbart, 2001). One of the most important pathogens affecting cyprinoid fish is A. hydrophila (Palmeiro & Roberts, 2009). Very recently, Abdel-Latif and Khafaga (2020) noticed mass mortality of cultured Nile tilapia and considerable economic losses due to the infections induced by A. hydrophila. Fluctuations in physico-chemical parameters such as salinity, temperature, pH, dissolved oxygen and water conductivity of cultured system could severely increase the rate of aeromonad infection in fish (Mzula et al., 2019).

The study evaluated the effect of Nigella sativa oil (NSO) and ciprofloxacin (CFX) on Oreochromis niloticus infected with Aeromonas hydrophila and Pseudomonas fluorescens through kidney function, histopathological changes of kidney and relative expression of interleukin 1β (IL‐1β) in fish organs. The studied fish were divided into four groups based on supplemented diets; each group was divided into three subgroups based on the type of the infection. The results showed increased levels of urea in all infected A. hydrophila and P. fluorescens groups while serum creatinine levels decreased in treated infected subgroups compared to controls. NSO and CFX treatments led to less histological damages in the kidney of infected groups despite the derangement of serum urea and creatinine levels. The up‐regulation of IL‐1β expression was varied based on the type of bacterial infection. After the bacterial infection, NSO led to down‐regulation of IL‐1β expression except in the kidney and gill in P. fluorescens infected subgroups while CFX led to up‐regulation of IL‐1β expression in most studied organs. A positive correlation was observed between serum urea levels and IL‐1β expression levels in the kidney, gill and liver while a negative correlation was observed between serum creatinine values and IL‐1β expression levels in the kidney and muscle. All the studied treatment modalities are effective in augmenting immune response and control of infections.

An update on the ornamental fish industry in Malaysia: Aeromonas hydrophila-associated disease and its treatment control

et al. 2021

View full text Add to dashboard Cite

Malaysia is the world's major producer and exporter of ornamental fish, contributing 9% to the global trade and taking the second position after Singapore. Because of their artistic appeal and tremendous commercial value for international trade, ornamental fish recently gain rapid importance for foreign exchange and as a source of employment. While ornamental fish production is growing, there is an increase in infectious diseases, resulting in high fish mortality with significant economic loss. Bacterial disease is a serious problem for ornamental fish industry. Bacterial species surveillance in diseased freshwater ornamental fish from an aquarium shop reveals that Aeromonas hydrophila is the most dominant bacteria isolated. Consequently, Malaysia is stepping up its efforts by implementing the Economic Transformation Program and other biosecurity steps to address the aquaculture issues and encourage the regrowth of the ornamental fish market. Chemotherapeutic medications, phytobiotics, probiotics, yeast extracts, vaccines, and disinfectants can be used in controlling bacteria. Further studies should be done to find new antibacterial agents from natural sources to combat bacterial fish diseases and reduce fish mortality rate in sustainable aquaculture farms. This review summarizes the literature on ornamental fish industries and aquaculture production in relation to A. hydrophila-associated diseases and ornamental fish health management in Malaysia.
