“…Water pH is another critical factor that can influence the prevalence and species richness of Dactylogyrus parasites. Dactylogyrus species have different pH tolerances, and fluctuations outside their optimal range can lead to reduced survival, reproduction, and infectivity (Bagge, 2005;Allalgua et al, 2021). Regarding to water salinity that can affect the prevalence and species richness of Dactylogyrus parasites.…”

The Cyprinidae fish’s gills are considered the permanent habitat for Dactylogyrids spp., common monogenean ectoparasites. This study aims to investigate the impact of monthly aquatic ecological dynamics on the diversity of Dactylogyrus. Moreover, the prevalence and species richness were correlated as well. A total of 140 fishes, representing 12 species from the family Cyprinidae, were collected from the Lesser Zab River, located in the northeast of Altuon-Kopri town, Kurdistan Region, Iraq. The study was conducted from August 2022 to July 2023. The collected fishes included: Acanthobrama marmid (37), Alburnus mossulensis (9), Barbus (B.) sharpey (5), Capoeta (C.) damascina (7), C. umbla (3), Carasobarbus luteus (10), Carassus (C.) auratus (13), C. carassus (3), Chondrostoma regium (18), Cyprinion macrostomum (5), Cyprinus carpio (26) and Luciobarbus xanthopterus (4). They were inspected weekly for diversity variation and richness of Dactylogyridis with different aquatic parameters such as pH, temperature, total dissolved salts (TDS) and electrical conductivity (EC). The collected data revealed the presence of various Dactylogyridis species with different prevalence and species richness. Monthly variations revealed that the highest species richness occurslowermost the lowermostoccurred in March 2023, and the lowest was observed in September 2022. According to aquatic parameters, only water temperature shows a significant negative correlation according to the species richness (p<0.05). In contrast, the other parameters show no significant correlation in accordance to the different months, monthly aquatic mean level of pH, TDS and EC were not correlated with species richness and prevalence of Dactylogyridis spp.

“…Avant le traitement, les valeurs étaient respectivement de 3,6863 mg/l, 2,0875 mg/l et 7,915 mg/l pour le magnésium, le calcium et le chlorure, tandis qu'après le traitement, elles sont de 6,0413 mg/l, 2,6225 mg/l et 11,460 mg/l. Les nitrates (NO₃⁻) présents dans les eaux naturelles proviennent de la décomposition naturelle de matière organique azotée, telle que les protéines végétales, animales, les produits agricoles et les excréments animaux, effectuée par des microorganismes [21], [22].…”

En vue d’améliorer la qualité de l’eau du lac Mandroseza, Antananarivo, Madagascar, une étude sur les caractéristiques physico-chimique et bactériologique des eaux brutes et traitées a été réalisé. Des échantillons ont été prélevés pendant 20 jours au cours du mois d'août 2023, durant la saison sèche. Ces échantillons ont fait l'objet d'analyses incluant les paramètres physico-chimiques et microbiologiques, suivies d'un traitement par la JIRAMA. Les résultats d’analyses ont montré une conformité générale aux normes malgaches en matière de qualité de l'eau, avec des variations mineures post-traitement mettant en avant l'efficacité du traitement, améliorant plusieurs paramètres clés de la qualité physico-chimique et bactériologiques du lac. Les températures moyennes, le pH, les conductivités électriques, la turbidité, le titre alcalimétrie, titre alcalimétrie complet, duretés total et calcique, fer total, calcium, magnésium, matières organiques, ammonium, chlorure, nitrite, nitrate, coliformes totaux, Escherichia coli, Streptocoques fécaux et Anaérobie sulfito-réducteurs des eaux brutes sont respectivement 18,63°C, 6,56, 40µS/cm, 10,55NTU, 0°f, 1,62°f, 17,2mg/l CaCO3 et 8,35mg/l, 2,29mg/l, 2,09mg/l, 3,68mg/l, 6,22mg/l, 0,32mg/l, 7,92mg/l, 0,06mg/l, 5,47mg/l, 57ufc/100ml, 14ufc/100ml, 48ufc/100ml et 40ufc/100ml. Après le traitement, ces valeurs ont été améliorés respectivement de 18,93°C, 7,12, 60µS/cm, 2,55NTU, 0°f, 0,57°f, 25,02mg/l et 10,52mg/l, 0,08mg/l, 2,62mg/l, 6,04mg/l, 2,72mg/l, 0,006mg/l, 11,46mg/l, 0mg/l et 0,56mg/l pour la qualité physico-chimique et aucune bactérie n’a été présent dans l’eau après le traitement. Malgré les niveaux élevés de germes bactériens dans l'eau brute dépassant les normes, les résultats post-traitement démontrent une amélioration significative, rendant les eaux propres à la consommation humaine grâce à l'efficacité du traitement effectué.

“…During the study, ammonia was detected in the N'Zi River at moderate concentrations (1.077 mg/L in December 2018 and 1.57 mg/L in June 2019), generally above those recommended (0.5 mg/L) by irrigation standards [15]. This reflects contamination of the waters of the N'Zi River by ammonia, the origin of which could be attributed to a biodegradation process of organic matter [16] [17] and to the leaching process of the agricultural land sur-rounding the dam [18]. These high concentrations of ammonia in water can lead to excessive algal growth that can harm aquatic life [19], while altering the quality of irrigation water [20].…”

This study aims to assess the physico-chemical quality of irrigation water and soil in the irrigated area of M'Bahiakro. Seasonal campaigns to measure in situ the physical parameters (pH, temperature, salinity, electrical conductivity and total dissolved solids) of the N'Zi River were carried out, followed by sampling (water and soil) for chemical analyses. The physico-chemical quality of irrigation water was assessed on the basis of four (4) parameters, namely Dry Residue (SR), Osmotic Pressure (π), Kelly's Coefficient (KC), Sodium Absorption Rate (SAR) and Wilcox Diagram. In terms of soil quality, the parameters (pH, N, P, P, K, MO, CEC and ESP) were determined. Overall, the results show a good physical-chemical quality of the irrigation water and soil. Indeed, the irrigation waters studied show good physico-chemistry and low to medium salinity depending on the seasons of the year. As for the soils, they have a clayey-silt texture, a slightly acidic pH, favourable to rice cultivation and a good organic matter content, which best maintains an active microbial life. In addition, the major elements (nitrogen, phosphorus and potassium) present in irrigation water and soils could be enough to optimize the yield of rice cultivation. These results then lead to the conclusion that the irrigation water from the N'Zi River and the soils of the irrigated perimeter of M'Bahiakro are naturally suitable for agricultural use, particularly for rice cultivation. As a result, an additional supply of fertilizer (NPK) would not necessarily be necessary during the exploitation phase of the rice area.
