“…Although relatively few studies have investigated the prevalence and distribution of food safety hazards in aquaponics systems, these systems are of increasing interest as a way to address food sustainability and security needs. Studies conducted in conventional and greenhouse production environments, and fish supply chains indicate that multiple pathways exist for the introduction of foodborne pathogens into hydroponic and aquaponic systems, including, but not limited to, fish feed, fish waste, the system's water, and the vegetable seeds [3,[23][24][25][26][27][28][29][30][31][32]. Due to the limited number of studies that investigated food safety hazards in aquaponics or hydroponics systems [27,[32][33][34][35], additional prevalence data are needed to fully characterize and manage food safety hazards associated with various aquaponics and hydroponics inputs.…”

Although many studies have investigated foodborne pathogen prevalence in conventional produce production environments, relatively few have investigated prevalence in aquaponics and hydroponics systems. This study sought to address this knowledge gap by enumerating total coliform and generic E. coli levels, and testing for Salmonella presence in circulating water samples collected from five hydroponic systems and three aquaponic systems (No. of samples = 79). While total coliform levels ranged between 6.3 Most Probable Number (MPN)/100-mL and the upper limit of detection (2496 MPN/100-mL), only three samples had detectable levels of E. coli and no samples had detectable levels of Salmonella. Of the three E. coli positive samples, two samples had just one MPN of E. coli/100-mL while the third had 53.9 MPN of E. coli/100-mL. While the sample size reported here was small and site selection was not randomized, this study adds key data on the microbial quality of aquaponics and hydroponics systems to the literature. Moreover, these data suggest that contamination in these systems occurs at relatively low-levels, and that future studies are needed to more fully explore when and how microbial contamination of aquaponics and hydroponic systems is likely to occur.

The prevalence of fish parasites in Bagrus bayad and Protopterus annectens from Upper River Benue in Mutum Biu, Taraba State, Nigeria was carried out using standard parasitological method. The objectives of this study were to investigate the parasite species spectrum, prevalence of each parasites species, overall prevalence, prevalence of parasite infection in relation to the size and sexes of Bagrus bayad and Protopterus annectens and the infection induced by parasites on/in their body parts, with the view of providing relevant information that can be used in combating the rate of economic losses that could be experienced as a result of parasitic infestations. 4 parasite taxa comprising of Twelve (12) parasite species (Trichodina spp., Henneguya spp. Cryptobia iubilans, Diphillobothrium latum, Hymenolepis nanna and Bothriocephalus aengypticus, Capillaria philipinensis, Caenorhabditis briggsae, Camallanus spp., Eustrongylides spp., Contracaecum spp. and Clinostomum spp. were recovered from the samples of fish species used during the study period. Twelve (12) of the parasite species were recovered from Bagrus bayad while seven (7) were recovered from Protopterus annectens. Among the body parts of Bagrus bayad, while intestine had the highest percentage parasite load (56.37%), highest percentage parasite load (46.22%) in Protopterus annectens was recorded for stomach (46.22%). Out of the 400 fish samples comprising of 200 each of Bagrus bayad and Protopterus annectens, 234 (58.50%) comprising of 99 (49.50%) and 135 (67.50%) samples each of Bagrus bayad and Protopterus annectens were infested with 369 and 119 parasites, respectively. However, there was no significant difference in the prevalence of infection and parasite load between the fish species, respectively (P>0.05). Generally, larger sized samples of Bagrus bayad and Protopterus annectens had higher percentage of infection compared to the smaller sized of both samples although, the prevalence of infection in relation to sizes of both fish species was not statistically significant (P>0.05). Female Bagrus bayad and Protopterus annectens had higher prevalence of infection (21.61%) and (16.63%) than the males (6.37%) and (6.24%), respectively. There was no significant difference in the prevalence of infection in relation to the sexes of both fish species (P>0.05). Epidermal necrosis of the caudal fin and skin, thickened intestinal epithelium at the site of parasite attachment, hyperplasia of the intestinal villi and lamina propria, hyperplasia of infected gills at the secondary lamellae, ulceration of the stomach, abdominal distention, eroded and flattened intestinal folds and lymphocytic infiltration of intestinal mucosa and edema of the lamina propria of the intestine were observed with the infected samples of B. bayad. The infected samples of P. annectens exhibited epidermal necrosis of the skin.

“…Once present in the pond, it can spread faecal matter from infected fish or other animals, as well as through contaminated water. In fish, Salmonella infections can cause a range of symptoms, including lethargy, loss of appetite, and abnormal swimming behaviour (Bibi et al, 2015). Salmonella can also contaminate the flesh of infected fish, potentially posing a risk to human consumers.…”

Good water quality is essential for a productive aquaculture system and to safeguard the health of the consumer. We assessed the quality of fishpond water in Phase 1, Mubo-Royal Valley fish farm in Ilorin, Kwara State, Nigeria. Water samples were collected in the 1 st and 3 rd weeks of fish breeding from three earthen and two concrete fishponds. The bacteriological and physicochemical parameters of the samples were determined in line with standard methods. Results showed that the pH, temperature, and dissolved oxygen (DO) values were within the recommended range of the National Environmental Standard and Regulations Enforcement Agency (NESREA). However, higher chemical oxygen demand (COD) values above the NESREA recommended range were recorded in the 1 st and 3 rd weeks of sampling in earthen Pond 1 and Pond 2, respectively. The Nitrate (NO 3 2-) and phosphate (PO 4 2-) contents of all sampling ponds were within the acceptable values of NESREA in the 1 st week of sampling. While significant (p < 0.05) increases in NO 3 2and PO 4 2were observed in earthen ponds in the 3 rd week. Copper and iron (mg/l) values were higher than NESREA recommended range, while lead and chromium values were within the range. Bacterial loads varied with the period of sampling with significant (p < 0.05) increases in the population of heterotrophic bacteria and Salmonella-Shigella in the 3 rd week of sampling. The nine bacterial genera isolated were Pseudomonas sp., Micrococcus sp., Staphylococcus sp., Salmonella sp., Escherichia coli, Enterobacter sp., Proteus sp., Streptococcus sp. and Bacillus sp. All the isolates were present in earthen and concrete ponds except Proteus sp. and Streptococcus sp. were absent in concrete ponds. Pseudomonas sp. had the highest frequency of occurrence while Streptococcus sp. had the lowest. Regular monitoring of water quality parameters is recommended to prevent potential risks associated with potential pathogens in fishponds.
