“…On the one hand, ectoparasite infection caused gill degeneration characterized by hemorrhage, excessive mucus production, and histopathology (Iwanowicz, 2011;Suliman et al, 2021). Additionally, gill morphological changes due to infection of ectoparasites can disturb the respiration's performance, adversely impacting fish growth (Nisa et al, 2021).…”

Studies related to the comparison of ectoparasites that infect snakehead from different habitats and their relationship to biometric conditions have not been widely studied. Thus, present study aimed to investigate the prevalence, intensity, dominance, and predilection of ectoparasites on snakehead collected from ditches, paddy fields, and swamps and correlate them with biometric conditions. In total of 90 snakehead fish were collected from ditches, paddy fields, and swamps. The observation of ectoparasites was performed on the gills, fins, and skin. The parameters measured in this study were ectoparasite profiles and biometric condition of fish. Specifically, the parameters of the ectoparasite profile included prevalence, intensity, dominance, and predilection. Meanwhile, the parameters of the biometric conditions were the length-weight relationship, the distribution of length and weight classes, and condition factors. Five species of ectoparasites that have been identified as Tetrahymena sp., Epistylis sp., Trichodina sp., Dactylogyrus sp., and Gyrodactylus sp. Tetrahymena sp. infection in snakehead was reported for the first time. The ditch habitat had the highest prevalence and intensity, which were 76.7% and 15.4 ectoparasites/fish, respectively. Tetrahymena sp. and Epistylis sp. were detected in sneakhead from all habitats, Trichodina sp. was detected at ditch and paddy field habitats, whereas, Gyrodactylus sp. and Dactylogyrus sp. were only found in swamp habitats. The gill was the predilection organ that most vulnerable to ectoparasite infection. Infected Snakehead tend to have lower average weight and length than healthy snakehead. Snakehead with a weight range of 115.2-145.2 g and a length range of 258.5-268.5 mm tend to be more vulnerable to ectoparasite infection compared to other sizes.Keywords:Tetrahymena sp.PrevalenceIntensityPredilectionLength-weight relationship

“…Infestation of ectoparasitic worms in the gills results in hyperplasia and fusion of the gill lamellae. Affected host fish will be thickened/swollen and pale red in color [15,[19][20][21]. Z. arugamensis in citric acid immersion at a concentration of 300 ppm attached to the body of the grouper appears to be released to the bottom of the water in a shrunken and dead condition.…”

Zeylanicobdella arugamensis infection causes health problems for cultured grouper. This study aims to determine the effectiveness of citric acid soaking as an anti Z. arugamensis ectoparasite. A total of ±120 Z. arugamensis were isolated from sick hybrid grouper (Epinephelus fuscoguttatus x E. lanceolatus) placed in Petri dishes (6 Petri dishes). Citric acid solution with 0, 50, 100, 150, 250, and 400 ppm was added to the petri plates. Immersion of Z. arugamensis was carried out for 30, 60, 90 and 120 minutes. Each 30 Z. arugamensis/treatment/30 minutes was taken and placed in 3 petri dishes (10 individuals/petri dish) filled with seawater. Observations were made on the response of Z. arugamensis. Comments were made on cocoon development into larvae. The citric acid safety test was conducted on cantang hybrid grouper infected with Z. arugamensis. A total of 3 test fish were soaked with citric acid solution in seawater at concentrations of 0, 150, 250, and 300 ppm. Observations of fish condition were made after 30 and 60 minutes of immersion. The results showed that citric acid concentrations of 250 and 400 ppm effectively killed Z. arugamensis (76.67±15.28-100%), and their cocoon development reached (0%). A citric acid concentration of 300 ppm is still safe to use for immersion of cantang hybrid grouper infected with Z. arugamensis for 60 minutes. Citric acid concentrations of 250-300 ppm can also release Z. arugamensis from the fish body. Citric acid has antiparasitic properties and lowers the pH of seawater.

“…According to [19] Z. arugamensis included leeches that obtain food by sucking blood from their host, did not have jaws but had a nutrient sucking device on the host called proboscyst [19]. Z. arugamensis infestation results in pale skin, redness and swelling [20]. The infestation would result in skin tissue damage.…”

Z. arugamensis was a parasite that often infested hybrid grouper (E. fuscoguttatus x E. lanceolatus). This study aimed to differentiate the Z. arugamensis intensity and the skin histopathology of hybrid grouper from concrete and soil ponds. The research method was a survey and data analysis using the IBM SPSS 21 Mann Whitney U Test. This study used 50 of hybrid grouper each from soil and concrete ponds. The intensity of Z. arugamensis from soil ponds was significantly different p < 0.05 with concrete ponds. Z. arugamensis infestation from soil ponds were 13 individuals including the intensity of Z. arugamensis in the medium category of 6.69 individuals/fish. Z. arugamensis infestation from concrete ponds were 10 individuals, including the intensity of Z. arugamensis in the light category was 2.9 individuals/fish. The results of histopathological scoring of hybrid grouper skin from soil ponds were significantly different, p≤0.05 with concrete ponds. The results of skin histopathological scoring of hybrid grouper from soil ponds were 1.1 for 13 fish while from concrete ponds it was 0.5 for 10 fish. This study showed that there was a significant difference in the intensity of Z. arugamensis and skin histopathology of hybrid grouper from concrete and soil ponds.
