“…Consumption of mycotoxin-contaminated food or feed can lead to acute or chronic toxicity in humans and animals. Mycotoxins show genotoxic, carcinogenic, and mutagenic effects, and some of them have immunosuppressive activity [95,96]. Through aquaponic water, these mycotoxins produced by diseased plants could disseminate and accumulate in fish.…”

The union of aquaculture and hydroponics is named aquaponics—a system where microorganisms, fish and plants coexist in a water environment. Bacteria are essential in processes which are fundamental for the functioning and equilibrium of aquaponic systems. Such processes are nitrification, extraction of various macro- and micronutrients from the feed leftovers and feces, etc. However, in aquaponics there are not only beneficial, but also potentially hazardous microorganisms of fish, human, and plant origin. It is important to establish the presence of human pathogens, their way of entering the aforementioned systems, and their control in order to assess the risk to human health when consuming plants and fish grown in aquaponics. Literature analysis shows that aquaponic bacteria and yeasts are mainly pathogenic to fish and humans but rarely to plants, while most of the molds are pathogenic to humans, plants, and fish. Since the various human pathogenic bacteria and fungi found in aquaponics enter the water when proper hygiene practices are not applied and followed, if these requirements are met, aquaponic systems are a good choice for growing healthy fish and plants safe for human consumption. However, many of the aquaponic pathogens are listed in the WHO list of drug-resistant bacteria for which new antibiotics are urgently needed, making disease control by antibiotics a real challenge. Because pathogen control by conventional physical methods, chemical methods, and antibiotic treatment is potentially harmful to humans, fish, plants, and beneficial microorganisms, a biological control with antagonistic microorganisms, phytotherapy, bacteriophage therapy, and nanomedicine are potential alternatives to these methods.

This study investigated the prevalence of Aspergillus sp. in tilapia sold for consumption at Pasarean Village in Bogor District. A total of 50 fish were sampled for further investigation. The clinical signs of fish were eroded fins, gills, haemorrhages, and wounds. The presence of pathogenic fungi was confirmed through fungal isolation from the skin, gills, and cloaca and subsequent culturing on potato dextrose agar. Macroscopic and microscopic observations determined Aspergillus sp. The results showed that four Aspergillus species were identified i.e., A. terreus (2%), A. flavus (4%), A. fumigatus (42%), and A. niger (4%), with the occurrence of co-infection between A. fumigatus and A. flavus (2%); A. fumigatus and A. terreus (2%); and between A. fumigatus, A. flavus, and A. niger (2%) reported a total prevalence of 58%. Further study is necessary to mitigate the crucial impact of fungal diseases in aquaculture systems, leading to effective prevention and control strategies, thus ensuring the safety and sustainability of aquaculture practices in Indonesia.
