Abstract:

The study examined helminth parasites of cultured Clarias gariepinus and Tilapia zillii in Uyo, Akwa Ibom State. A total of 60 fish samples (30 each of C.gariepinus and T. zillii) were subjected to parasitological examinations. Results revealed a total of 47(78.33%) fishes infected with various species of parasites: Nematodes (Camallanus polypteri, Paracamallanus cyathopharynx, and Procamallanus laevionchus), Cestodes (Polyonchobothrium torulosus and P. clariae) and Trematodes (Dactylogyrus extensus and Glossiduim pedatum) in decreasing order of abundance. Out of the 60 fish samples examined, 47 were infected with 219 parasites: 142(64.84%) nematodes, 40(18.26%) cestodes and 37(16.89%) trematodes. A total of 159(72.60%) parasites were recovered from C. gariepinus out of which 103(64.78%) were nematodes, 19(18.45%) were cestodes and 37(35.92%) were trematodes. While 60(27.40%) parasites were recovered from T. zilli, of which 39(65.00%) were nematodes and 21(35.00%) cestodes. No trematode was observed in the tilapia. The overall prevalence of parasitic infection was 78.33%. The results of chi square analysis showed that females of both species had significantly higher (P<0.05) prevalence of infection 27(84.4%) than males 20(71.4%). Also, C. gariepinus had higher infection rate of 25(83.33%) when compared to 22(73.33%) recorded in T. zillii. Key words: fish parasites, aquaculture, prevalence, C. gariepinus, T. zillii

Abstract:

Two catfish: Clarias batrachus (Linnaeus) and C. gariepinus (Burchell) were selected for examination during June, 2014 to May, 2016. The percentage (g/100 g) of nutrients such as moisture, ash, fat, protein, carbohydrate contents (mg/100 g) and energy (K cal) in C. batrachus and C. gariepinus was determined. Analyses were done to measure the nutrition value of edible body parts (flesh) of C. batrachus and C. gariepinus. The effects of modifying factors such as, season, sex, length, and diet of the hosts on the abundance of parasites were also studied. Present observation on biochemical analysis showed small variation in nutrient contents between C. batrachus and C. gariepinus. Protein, fat, moisture, carbohydrate levels were higher in non-infected C. batrachus (moisture 78.25 ± 0.06 g/100 g, ash 1.42 ± 0.09 g/100 g, fat 1.20 ± 0.04 g/100 g, protein15.05 ± 0.19 g/100 g, carbohydrate 5.53%) and non-infected C. gariepinus (moisture 78.62 ± 0.01 g/100 g, ash 1.22 ± 0.10 g/100 g, fat 1.19 ± 0.03 g/100 g, protein 14.69 ± 0.07 g/100 g, carbohydrate 4.95% than those of infected C. batrachus and C. gariepinus. In both species the highest presence of most of the nutrient components was observed in winter. Bangladesh J. Zool. 47(1): 27-39, 2019

Abstract:

AbstractThe factors that determine parasite assemblages among the clariid fishes of Lake Victoria, Tanzania were studied between August 2003 and February 2005. Six hundred and fifty-six fish belonging to seven species were necropsied and examined for parasites, from which 31 species of metazoan parasites were recorded. The community was dominated by the nematodes both in species and numbers. Most species were generalists with only two trematodes, Diplostomum mashonense and Tylodelphys species, being specialists of Clarias gariepinus. Ten species were considered core and predictable. Parasite species richness, number of individuals per host and Shannon–Wiener diversity indices were generally high. At the compound community level, a mean number of 7.8 parasites were shared among different species of fish and the maximum number of parasites species per fish at the infracommunity level was seven. Levels of similarity in parasite species richness at the component community level ranged from 29.6 to 61.5%. The study concludes that parasite communities in clariid fishes of Lake Victoria are structured by ecological factors. At the infracommunity level, host size, diet and vagility promoted a richer parasite community. At the compound level, two factors were crucial, namely the intermixing of the waters in the lake and the predominant and mobile C. gariepinus.

Abstract:

Abstract Clarias gariepinus is a fish from North of South Africa and was later introduced in several countries, including Brazil. The present study aimed to describe the first report of Diplostomidae metacercariae in C. gariepinus in Brazil. For this, 30 C. gariepinus were captured in a lake in the city of Campos dos Goytacazes, RJ, Brazil. Fishes were euthanized using freezing and necropsied for collection of parasites. The organs were dissected and analyzed for the presence of parasites that were processed for light and scanning electron microscopy. Trematodes were stained with Semichon’s Carmine and Gomori’s Trichrome, observed and schematized under a light microscope with image analysis software. A total of 190 trematodes were collected from the gills, suprabranchial organs, heart, stomach, intestinal mesentery, liver and body cavity of the fish. The parasites had a foliaceous body divided by a discrete constriction, without genital primordia, and a holdfast organ present at the posterior region, typical of metacercariae of the family Diplostomidae. It was classified as the 'Diplostomulum' morphotype, based on the morphology of the reserve bladder structure. This is the first report of the metacercariae of Diplostomidae parasitizing C. gariepinus in the Americas. This fish acts as an intermediate or paratenic host of this digenean in Brazil.

Abstract:

The study of teleost parasites in an ecologically altered ecosystem through dam construction that evidently facilitate parasitic infections and aggravate public health concerns is essential. The study of stream linked dam showed that Tilapia zillii (Gervais, 1848), Pelmatolapia mariae (Boulenger, 1899) and Clarias gariepinus (Burchell, 1822) form the major fish composition of these reservoirs. They serve important food resource globally especially places bereft of extensive aquaculture practices. Although, knowledge about the gill parasites of P. mariae is inexistent the examined individual P. mariae showed that it had 54% Heterophyes heterophyes infection, C. gariepinus had no parasitic infection whereas T. zillii had a relatively very low Batrachobdelloides spp (1.7%). Besides, the highest DO levels in the dam occasioned by high agitation and floatation the physical factors conditions - pH and DO (> 6 mg.L^-1) had suitable levels for biodiversity.

Abstract:

AbstractThe relationship between parasite species diversity and organic pollution in the upper Manyame catchment, Zimbabwe, was investigated between October 2006 and January 2007. The parasite assemblage comprised 13 species in total. Species richness in the unpolluted sites was high; in the moderately polluted sites, it was low, while in the polluted sites, only one parasite species was encountered. Component community diversity, as measured by the Shannon index (H′), decreased with increase in organic pollution. The distribution and occurrence of ectoparasites (Dolops ranarum, Lamproglena clariae, Chonopeltis sp. and Macrogyrodactylus sp.) and one endoparasite (Lytocestus sp.) were limited to the unpolluted sites, demonstrating their sensitivity to organic pollution. The prevalence of the nematodes Paracamallanus cyathopharynx, Procamallanus laevionchus and Contracaecum spp. larvae decreased along the pollution gradient, showing their high sensitivity to organic pollution. The platyhelminths Diplostomum sp. and Polyonchobothrium clarias were the most tolerant and occurred at both polluted and unpolluted sites. Proteocephalus sp. and Caryophyllaeus sp. were limited to the polluted sites, probably as a result of high abundance of oligochaetes and copepods, their intermediate hosts that thrive in sewage-enriched sediments, at the downstream sites. The observed results assume that the decrease in parasite diversity can be related to increased organic pollution. Some parasites requiring complex life histories were absent along with pollution-related disappearance of their vector hosts. Further studies should address the identification of parasite life stages that are more sensitive to pollutants.

Abstract:

Knowledge of the endemic fauna of parasites in fish are of great importance, parasites could synergistically act as stressors to health of their hosts. The objectives of this study were to evaluate prevalence and effect of parasites on hematological, biochemical indices, injury of tissues and length weight relationship of Clarias, gariepinus. Water quality variables were measured and fishes were collected each seasons for examination most common parasites in infected fishes at Abbasa Fish Farm, Egypt. Results indicated that high summer water temperature was strongly associated with parasites infection. The hematological and biochemical analysis showed significant reduction in red blood cells (RBCs) count, hemoglobin (Hb) value, packed cell volume (PCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC), total protein, Albumin, Globulin and A/G ratio, while total white blood cells (WBCs) count, mean corpuscular volume (MCV), aspartate aminotransferase activity (ASAT), alanine aminotransferase activity (ALAT), urea, creatinine, uric acid and glucose were significantly increased in infested catfish. On other hands, histopathological examination of infected fish indicated, organs most affected by infection of parasites. Overall the tendencies observed in data showed the parasites have a strong effect on host fish and drifts observed for all variables showed a strong seasonal decoration.

Abstract:

AbstractIn an aquatic environment, there is a profound and inverse relationship between environmental quality and disease status of fish. Parasites are one of the most serious limiting factors in aquaculture. Therefore, the present investigation was carried out during the period of February–December 2014 to determine the parasitic infections in the African sharptooth catfish Clarias gariepinus, relative to the capability of internal parasites to accumulate heavy metals. Up to 100 catfish were examined for gastrointestinal helminths and 38% of fish were found to be infected with the cestode Polyonchobothrium clarias. The morphology of this parasite species, based on light and scanning electron microscopy, revealed that the adult worm was characterized by a rectangular scolex measuring 0.43–0.58 (0.49 ± 0.1) mm long and 0.15–0.21 (0.19 ± 0.1) mm wide, with a flat to slightly raised rostellum armed with a crown with two semicircles each bearing 13–15 hooks, followed by immature, mature and gravid proglottids which were about 29–55 (45), 16–30 (24) and 15–39 (28) in number, respectively. The mature proglottid contained a single set of genitalia in which medullary testes measured 0.09–0.13 (0.11 ± 0.01) mm long and 0.05–0.08 (0.06 ± 0.01) mm wide; a bi-lobed ovary was situated near the posterior margin of the proglottid, extending laterally up to the longitudinal excretory canals; the tubular uterus arose from the ootype up to the anterior margin of the proglottid; and vitelline follicles were cortical. The greater portion of the gravid proglottid was occupied by a uterus filled with unoperculate and embryonated eggs. Chemical analysis confirmed that the concentrations of heavy metals (Zn, Cu, Mn, Cd, Ni and Pb) accumulated in P. clarias were higher than in fish tissues and values recommended by FAO/WHO, with the exception of Zn, which was found to be higher in fish kidneys than in the cestode. This supports the hypothesis that cestodes of fish can be regarded as useful bioindicators when evaluating the environmental pollution of aquatic ecosystems by heavy metals.

Abstract:

Penggunaan bahan kimiawi yang aman dan ramah lingkungan merupakan salah satu metode yang banyak digunakan untuk pengobatan penyakit parasitik pada budidaya ikan, meskipun masih sedikit informasi mengenai efektivitas penggunaan hidrogen peroksida untuk pengobatan penyakit parasitik pada ikan air tawar di Indonesia. Penelitian bertujuan untuk mengetahui dosis efektif hidrogen peroksida (H2O2) dan pengaruhnya terhadap infeksi ektoparasit pada ikan lele Clarias gariepinus. Perlakuan yang digunakan adalah penambahan H2O2 dalam media pemeliharaan dengan dosis berbeda yaitu: (A) aplikasi H2O2 dosis 100 mg/L, (B) aplikasi H2O2 dosis 200 mg/L, (C) aplikasi H2O2 dosis 300 mg/L, dan (D) tanpa aplikasi H2O2 atau kontrol. Pemberian hidrogen peroksida dilakukan satu kali pada awal pengujian dan tiap perlakuan menggunakan tiga ulangan. Pemeriksaan sampel dilakukan setiap hari terhadap tingkat infestasi dan prevalensi ektoparasit selama enam hari pemeliharaan. Pengamatan hanya dilakukan pada parasit dewasa yang memiliki organ tubuh lengkap dan telah melewati fase telur. Fokus penelitian untuk memperoleh informasi dosis H2O2 yang paling efektif menekan infeksi ektoparasit selama enam hari pengujian. Hasil penelitian menunjukkan bahwa aplikasi hidrogen peroksida dosis 300 mg/L efektif menekan tingkat infestasi dan prevalensi parasit Trichodina sp., Dactylogyrus sp., dan Gyrodactylus sp., diikuti dosis 200 mg/L, 100 mg/L, dan terendah pada kontrol. Berdasarkan analisis statistik diperoleh nilai infestasi parasit yang berbeda nyata (P<0,05) antara perlakuan aplikasi H2O2 dibandingkan dengan kontrol atau tanpa aplikasi H2O2.Chemical compounds that are safe and environmentally friendly has been widely used to treat parasitic diseases in fish farming. However, there is limited information on the effectiveness of the application of hydrogen peroxide to treat parasitic diseases in freshwater fish in Indonesia. The study was aimed to determine the effective dose of hydrogen peroxide (H2O2) and its influence on the presence of ectoparasites on Clarias gariepinus catfish. The treatment used was the addition of H2O2 in the media preservation at different doses, namely: the application of H2O2 dose of (A) 100 mg/L, (B) 200 mg/L, (C) 300 mg/L, and (D) without H2O2 or control. Treatment media were exposed to hydrogen peroxide once at the beginning of the test and each treatment used three replications. Infestation and ectoparasite prevalence were observed daily for six days. The observations were only performed on adult parasites that have complete organs and passed the egg stage. The study focuses on obtaining the most effective dose of H2O2 to suppress ectoparasite infection within six days. The results showed that the application of hydrogen peroxide of 300 mg/L was the most effective dose to suppress the infestation level and prevalence of Trichodina sp., Dactylogyrus sp., and Gyrodactylus sp., followed by 200 mg/L, 100 mg/L, and the lowest was in control. The statistical analysis of the parasite infestation had shown a significant difference (P<0.05) between the treatment of H2O2 as compared with the control.

Abstract:

This research was carried out to quantify the burden of gastrointestinal helminthes of fish sold in Makurdi, Nigeria. A total of 800 fish samples consisting of four species (Alestes nurse, Tilapia zilli, Oreochromis niloticus and Clarias gariepinus) were purchased from fisher men at Wadata and Wurukum landing sites and taken to the Zoology Laboratory of Benue State University Makurdi for analysis. The length and weight of the fish samples were taken prior to dissection and parasites were recovered and identified following standard procedures. Data generated was analyzed using descriptive statistics and chi square. Results indicated an overall prevalence of 90(11.25%) consisting of four parasite groups: Nematodes 74 (660.7%), Cestodes 10(8.93%), Trematodes 18(16.07%) and Acanthocephalans 10(8.93%) (P<0.05). Infection rate was higher (57.78%) in fish length range 21.00 - 25.9cm while those that fell within 6.00 -10.90cm and 11.00 – 15.90cm were not parasitized (P<0.05). It was also observed that fish within the standard weight range of 80.00g – 120.9g had the most number of parasites (p>0.05). Parasite density was highest (2.33%) in O. niloticus. The helminthes recovered were found to inhabit the Intestine 66(58.93%), Stomach 22(19.64%), Liver 20(8.92%), Gills 8(3.57%) and Muscle 6(5.36%) (P<0.05). Proper fish handling and preparation as well as screening of wild juveniles and parent stock is recommended to enhance aquaculture and prevent zoonosis

Abstract:

The postembryonic development of the gill parasite, Lamproglena clariae, infecting the sharp tooth catfish, Clarias gariepinus was established from egg culture and artificial infection of fish under laboratory conditions. Like most fish parasitic copepods, L. clariae has a direct life cycle utilizing only a single fish host species. Adult post metamorphosis females produce two egg strings. The mean number of eggs in each egg string was 52. Three naupliar and first copepodid stages were obtained in culture while two copepodid stages, cyclopoid and adult specimens were obtained after artificial infection of catfish in aquaria. First stage nauplii were globular in shape and densely filled with yolk. Nauplii lacked a perforation for the mouth and masticatory parts of the appendages, all of which indicate that they do not feed. Body architecture of the first copepodid stage of L. clariae is similar to that of all other copepods in the number and kind of somites: a cephalothorax with five appendages, three thoracic somites, one abdominal somite and furca rami. This seems to be a conserved morphology among the copepods. The three naupliar and three copepodid stages are described and compared to related copepods.

Abstract:

SUMMARYMacrogyrodactylus spp. from the gills of Clarias gariepinus in Zimbabwe and Kenya, and C. anguillaris in Senegal were identified using haptoral sclerite morphology and by sequencing the nuclear ribosomal DNA internal transcribed spacers (ITS) 1 and 2, partial 18S and the complete 5·8S rRNA gene. A molecular phylogeny was constructed using all sequenced Macrogyrodactylus species to date. Based on morphology, Macrogyrodactylus congolensis, M. heterobranchii, M. clarii, and M. karibae were identified, with one specimen from Zimbabwe displaying morphological features that were intermediate between M. heterobranchii and M. clarii. In the intermediate form, the partial 18S and ITS1 sequence was identical to that of M. clarii while the remaining ITS1 and complete ITS2 region was almost identical to M. heterobranchii as was the partial cox1 fragment, thus strongly suggesting a hybrid origin. At present, the catfish host of M. heterobranchii and M. clarii do not co-occur in southern Zimbabwe; this hybridization event is therefore proof of historical sympatry of both fish species.

Abstract:

Sangkuriang catfish (Clarias gariepinus) is a leading commodity of Indonesian freshwater fishery. Production continues to increase in 2016 reached 22%. cultivators experience constraints on seeding and enlargement due to ectoparasites Trichodina sp. this parasite attacks the outer part of the body marked by the spots on the body. Prevention and treatment of many usses of chemicals that can adversely affect the human body and environtment, so it takes another alternative to replace these chemicals that can adversely affect the human body and environment, so it takes another alternative to replace these chemicals. Cherry Leaf contain compounds Flavonoid, Tannin, Triterpenoid, Saponin and Polifenol as antioxidants, Cherry Leaf useful as an antibacterial. The method used in this research is the experimental method and using Completely Randomized Design (RAL). Concentrations of cherry leaf extract (Muntingia calabura) given include 1%, 2%, 3%, 4% and 5% there were 5 treatments and 4 replications. The data obtained were analyzed by ANAVA method (variance analysis) followed by LSD test. The results showed that the use of cherry leaf extract (Muntingia calabura) in treating Trichodina sp parasite has a very real effect with the best value on the presentation of Leukocrit is 2% concentration that produces Leukocrit percentage of 2.68% and percentage of Hematocrit 2% with Hematocrit yield of 11.83%. The clinical symptoms are white spots in all body, pale color, decreased appetite of the mucus that comes out, often rubbing the body to the wall. The result of water quality measurement shows temperature: 24 - 27,2oC, DO: 4,1 - 6,9 and pH: 6 - 8.KEY WORDS: Muntingia calabura, Trichodiniasis, Sangkuriang Catfish, Leukocrit, Hematocrit.

Abstract:

Fish is significant as a vector of disease pathogen of human and animals. The study of the helminthes parasites of Clarias gariepinus in Abraka was carried out to investigate the occurrence, prevalence and intensity of helminthes parasites in Clarias gariepinus; and to compare the helminthes parasites burden of the wild and cultured Clarias gariepinus in Abraka fresh water. A total number of four hundred and nine (409) Clarias gariepinus were examined. Collection of fish samples was done monthly for twelve months. The external parts of each fish were examined with a hand lens for the occurrence of helminthes parasites. Portions of the muscles were also teased apart in saline water and examined under the microscope first at x 40 and later x 100 oil immersion. Organs of the body were examined separately in petri dishes containing normal saline. The different groups of parasites recovered were preserved in formaldehyde and identified using prescribed methods. Of the 409 C. gariepinus examined, 172 were infected, showing an infection rate of 42.1%. C. gariepinus from the wild had a higher prevalence of 31.1% while those from culture ponds had a lower prevalence of 11%. A total of 485 parasites were recovered, comprising of 113 trematodes and 372 nematodes which represents 23.3% and 76.7% respectively. Identified trematodes included Diplosomum sp., Macrogyrodactylus sp., and Quadriancanthus sp., while namatodes included Procamallanus sp. and an Ascarid nematode. The highest intensity of infection of 3.11 was recorded in the Ascarid nematode while the least of 1.25 came from Diplostomum sp. in C. gariepinus caught from the wild. Although, there appears to be a lack of reported cases of the occurrence of the ascarid nematode that was recovered from the muscles of C. gariepinus in literature, it is evident from this study that it is a common endoparasite of the African catfish in Abraka freshwater.

Abstract:

Abstract Background The study was conducted to compare parasitic loads of Clarias gariepinus from cultured and natural habitats. A total number of 80 live adults (200–799 g) C. gariepinus comprising of 20 each were randomly obtained from two cultured habitats (ponds) and two natural habitats (rivers). In the laboratory, these fish were all examined for the presence of parasites. Their sexes were identified while the lengths and weights were measured and recorded prior to dissection. The parasites observed were also identified using morphological characteristics. Results Out of the 80 C. gariepinus sampled, 43 (53.75%) were infected and a total of 409 parasites comprising of 141 (34.47%) ectoparasites and 268 (65.53%) endoparasites were observed from the infected fish. The prevalence of parasitic infection in cultured and natural habitats was 20% and 33.75%, respectively. The results showed that there was a significant difference (P < 0.05) in parasitic infection of C. gariepinus obtained from cultured and natural habitats. Parasitic loads were observed to be significantly higher in natural habitat (33.74% and 26.16% for river A and river B, respectively) compared to cultured habitat (20.54% and 19.55% for pond A and pond B, respectively). The prevalence of parasites in relation to sexes of C. gariepinus was not significantly different (P > 0.05) for both habitats. It was also noted that catfishes with body weight 500–599 g had the highest prevalence (100%) both in cultured and natural habitats. Conclusions The study showed that the parasite loads were more in C. gariepinus obtained from natural habitat compared to those obtained from cultured habitat. It is therefore recommended that the sanitary conditions under which fishes are reared in fish pond should be improved and fish stocked from natural habitats or unscreened ponds should be quarantined to eliminate and treat possible parasitic infection before introducing them into other fish ponds.

Abstract:

Aims: To determine condition status and identify parasitic fauna in intestine, gills and skins of Clarias gariepinus collected from two natural waters: Ogbese River (River A) (Longitude 5°26'E' and Latitude 6°43'N), and Owena River (River B) (Longitude 5.03E and Latitude 7.03N) in Ondo state, Nigeria respectively. Study Design: Laboratory-experimental design was used in this study. Place and Duration of Study: 120 live C. gariepinus African Mud Catfish were collected by the assistance of fishermen using cast net during the wet season during April to July 2016 from the two natural water bodies (Ogbese River and Owena River). Methidology: Fish were transported live to the laboratory for examinations. Length (cm) and weight (g) measurement of fish were determined. Condition factor (K), isometric value (b) and regression coefficient were determined. Fish samples were examined using electronic Microscope (x 400 Mag.) by dissecting fish to remove organs (Intestines, gills and skins) for parasites occurrence (s). Descriptive and analytical statistics were used to analyse the data obtained. Results: The condition factor for all C. gariepinus samples collected from both Rivers were less than one (<1), which indicated that the health status of the fish is biased, and the environment is not conducive. The parasitic examination carried out revealed that seventy-eight (65%) C. gariepinus fish samples were infested; while 42 (35%) of fish samples showed no parasite infestation. A total of Ninety-six (96) individual parasites were recovered from River A while a total of two hundred and twelve (212) individual parasites were recovered from River B. A total of eight (8) different parasites species were recovered while their percentage of occurrence was recorded. These include Ambiphrya spp. (4.17%), Camallanus spp. (6.25%; 2.83%), Capillaria spp. (16.98%), Chilodonella spp. (14.58%), Dactylogyrus spp. (64.58%; 5.66%), Diphyllobothrium latum (10.42%; 4.72%), Gyrodactylus spp. (61.32%) and Protoopalina symphysodonis (8.49%). Conclusion: The water bodies need to be protected against further pollutants to prevent disease condition for the benefit of aquatic organisms and public health.

Abstract:

Clarias gariepinus were collected from Lake Chivero, Zimbabwe, and examined for nematode parasites from November 2000 to May 2002. Of the 202 specimens collected, 42.6 % were infected with third-stage larvae of Contracaecum sp. in the body cavity. The intensity of the infection was 1-7 worms per fish (mean intensity = 2.2). Seasonal variation in the prevalence of the parasite was not obvious and there was no significant difference in the prevalence of infection between males and females (c2 = 2.228; P > 0.05). No significant relationship between host size and prevalence was established. There was also no significant relationship between intensity and the body condition factor (r = 0.11; P > 0.05). The low parasite prevalence may have been caused by the disruption of the infection cycle since piscivorous birds, which are the final hosts of the parasite, do not feed on C. gariepinus in Lake Chivero.
