“…Conversely, in a study by Suliman et al (2021) where there was a substantial deterioration of fish pond water of Oreochromis niloticus, sampled water showed low oxygen, high ammonia, and nitrite with the examined fish presenting with severe alterations, blood hemorrhage, the fusion of secondary lamella, erosion and mucus secretions of the gills and the disease severity resulting in the death of some individuals. The histopathology of the fish gills indicated ectoparasites, one of which was Trichodina.…”

This experiment investigated the impact of two water sources and their quality on the survival, growth and health of Clarias gariepinus fingerlings reared in indoor concrete tanks. 400 fingerlings of mean weight 15.33±3.47 g and total length 12.63±1.00 cm (mean±standard deviation) was randomly distributed into four concrete tanks of 12 m3 capacity each. Water quality was analyzed bi-weekly throughout study duration. Growth parameters such as mean weight gain (MWG), specific growth rate (SGR) and feed conversion rate (FCR) were calculated using standard procedures. At study termination, duplicate groups per treatment were assessed for survival rate and a health status check was determined by a hematological evaluation and microscopic examination of parasitic incidence. Results indicated that fish reared in water sourced from bore-hole [BH] performed comparatively significantly better in growth (p < 0.05) than fish in water from earthen pond [EP] as the MWG stood at 294.05±79.17 g for the former against 211.03±54.62 g for the latter with the survival rates for both treatments being in excess of 90%. Additionally, fish reared in EP presented with a higher infestation load of Trichodina spp., although there was no significant difference (U = 7, p > 0.05) between fish reared in EP and BH treatments with regards to their packed cell volume levels and white blood cells. The outcome of this study shed light on the impact a water source can have on the growth and health status of C. gariepinus with a recommendation of microbiological analysis of water supply from open/surface systems before usage for the African catfish aquaculture.

“…The presence of parasites in fish gills reduces the gill surface area, causes disturbances of hydromineral balance, increases ATP-ase expression and induces apoptosis in mitochondria-rich cells ( Oğuz & Oğuz, 2020 ). This mechanism causes reduced oxygen entering the fish, the color of the gills becomes pale, uncertain movement, fade color, stress, and even mortality ( Suliman et al, 2021 ). Besides gills, skin is a favorite place for parasites to attach.…”

Assessment of fish health is one of the efforts of farmers in minimizing losses due to disease. Rapid tests on fish health can be done through blood observations. This study aimed to determine the blood glucose profile of koi carp due to ectoparasite infestation from the level of blood glucose. The results showed that reported parasites from Blitar’s koi carp were Trichodina, Dactylogyrus, Gyrodactylus, Myxobolus, Thelohanellus, Ichthyophthirius, and Argulus. Trichodina showed the highest prevalence (100%) in this case while Thelohanellus was the highest intensity level (93.8±16.3). The results of blood glucose level measurement based on parasite infestation levels showed no significant difference (p>0.05) though the health problems caused by parasites in light, medium or heavy infestation. This research also indicated that the blood glucose profile could be used as a rapid method to detect fish health caused by parasites. We suggest that other variables such as nutritional status, life stage or feeding must be conducted to ensure the glucose role in parasite identification as a rapid method for the future work.

“…The study showed that histopathological analysis for parasites in fish is a valuable tool for fish health monitoring. Similarly, Suliman et al (2021) found that histopathological changes induced by ectoparasites on fish gills and skin could be used to determine the severity of ectoparasite infection, which can help improve fish farm management and produce healthier fish for human consumption.…”
