Department of Marine Sciences, Faculty of Science, University of Lagos, Akoka Yaba, Lagos, Nigeria *Corresponding author: [email protected]; [email protected] ABSTRACT Parasites in three economically important fishes (Ethmalosa fimbriata, Chrysichthys nigrodigitatus and Sarotherodon melanotheron) from Lagos Lagoon were studied between March and August, 2015. Out of 90 specimens analyzed, a total of 41 (45.6%) specimens were infected with parasites having a total parasite count of 735. Glochida accounted for the most abundant parasite in the gills and skin of C. nigrodigitatus having a prevalence of 43.81%, Ergasilus sp. had the least amount of prevalence with 0.41%, Gyrodactylus had a prevalence of 6.80%, Neobenedenia had a prevalence level of 0.95%. Larvae forms of Eustrongylides from S. melanotheron had a prevalence level of 4.08% while Piscinodinium which was identified from the gills of both S. melanotheron and E. fimbriata had a prevalence level of 41.36%, an unidentified worm had a prevalence of 2.59%. Human beings who consumed raw or under - cooked fish that are infected with larval stages of Eustrongylides have experienced gastritis or inflammation of the stomach and intestinal perforation requiring surgical removal of worms. Key words : Parasite, fish, gill, skin, under - cooked, gastritis intestinal perforation INTRODUCTION Fishes are important to man as they serve as a good source fecundity reduction (Nmor et al.,2004) and mechanical of animal protein for both man and livestock. It also serves injuries depending on the parasite species and load (Echi et as a source of income in Nigeria and other countries in sub- al., 2009a, b). Fish is the most parasitized vertebrate and the Saharan Africa where some 35 million people depend presence of parasite is detrimental to fish population which wholly or partly on the fisheries sector for their livelihood may cause high mortality, weight loss and reduced (FAO, 1996). fecundity on both farmed and wild fish species especially Many diseases found in fish are closely linked to in waters contaminated with industrial and urban pollutants environmental degradation and stress; once the (Ramollo, 2008). In instances where host are overcrowded environment is disturbed the organisms too become such as in aquaria’s and fish ponds, parasitic disease can stressed (SEAFDEC, 1999). Parasitism, according to spread very rapidly causing large mortalities (Parpena, Marcogliese (2002) reflects a life style whereby one or 1996) while in natural systems they may threaten the more individual organisms (the parasites) live in close abundance and diversity of indigenous fish species obligate association in or on another (the host) and derives (Mashego, 2001). nutritional benefits at the host’s expense, usually without Parasites can be divided into micro-parasites and killing the host. Parasites are a major concern to freshwater macroparasites on the basis of size, the micro-parasites and marine fishes all over the world, and of particular include viruses, bacteria, fungi, protozoans, micro- importance in the tropics (Iyaji and Eyo, 2008; Bichi and sporidians and mixozoans.

They constitute a fish hosts, most often consider only protozoans major limiting factor to the growth of farmed fish in Nigeria (Marcogliese, 2002). Macro-parasites are multicellular (Bichi and Yelwa, 2010). The effects of parasites on fish organisms mainly comprised of the helminthes and include nutrient devaluation (Hassan et al., 2010); arthropods. Furthermore, parasites can also be divided into alteration of biology and behaviour (Lafferty, 2008); ecto-parasites and endo-parasites on the basis of their lowering of immune capability, induction of blindness location in the fish’s body. Ecto-parasites are those found (Echi et al., 2009 a, b); morbidity, mortality, growth and on the external surfaces such as skin or gills while endo- 52 Parasite in fishes from Lagos lagoon parasites are those housed within internal organs or cavities year with 64% prevalence.

  • The Ecology and Emergence of Diseases in Fresh Waters
    Freshwater Biology (2011) 56, 638–657 doi:10.1111/j.1365-2427.2010.02546.x The ecology and emergence of diseases in fresh waters PIETER T. J. JOHNSON AND SARA H. PAULL Ecology and Evolutionary Biology, University of Colorado, Boulder, CO, U.S.A. SUMMARY 1. Freshwater ecosystems, including ponds, lakes, streams and rivers, represent an interaction nexus between environmental change and a wide variety of infectious diseases, including human malaria, salmonid whirling disease, amphibian chytridiomycosis, crayfish plague and many others. However, few studies have explicitly examined patterns of disease in fresh waters and how they are changing over time. 2. Freshwater environments can function as transmission foci for pathogens because of (i) the importance of fresh water for organism survival, (ii) the aquatic life histories of many vectors and intermediate hosts, (iii) the concentrated aggregations of species – both freshwater and terrestrial – in and around freshwater habitats and (iv) the highly altered condition of freshwater ecosystems, which can affect species interactions and disease pathology. 3. To determine whether water-related diseases in wildlife are increasing, we used generalised additive models to quantitatively assess trends in the scientific literature (1970–2009) for major freshwater groups, including amphibians, molluscs, crayfishes, fishes, mammals, reptiles and birds. We further examined what types of pathogens were primarily responsible for observed patterns and whether recurrent groups or transmission modes could be identified. 4. After correcting for research effort and temporal autocorrelation, we find that reports of disease varied over time and across freshwater taxa, with significant increases in amphibians, fishes and crayfishes, a significant decrease in molluscs, and no significant change in freshwater reptiles, birds or mammals.

In this regard 30 fish were studied for abdominal cavity parasites in February 2014. Results showed all of the specimens were infected at least with one kind of parasite and there was no significant difference in parasitic infections between males and females. According to the results three kinds of parasites including one trematode (Pronoprymna ventricosa) and two kinds of nematodes (Anisakis simplex and Eustrongylides sp) were isolated from the abdominal cavity of the studied fish. 43.33 % of the specimens were infected with A. simplex, 96.66 % were infected with P. ventricosa and 16.66 % of the specimens were infected with Eustrongylides sp. Intensity of infection to A. simplex, P. ventricosa and Eustrongylides sp in saposhnikovi shad was calculated as, 3.46 ± 1.76, 131 ±16.78 and 2 ± 0.71, respectively. According to the results 33.33% intestine, 10% liver and 6.66% mesentery of specimens were infected with A. simplex, 26.66% stomach, 86.66% pyloric caeca and 66.66% intestine of studied fish were infected with P. ventricosa and Eustrongylides sp was isolated in 13.33% mesentery and 3.33% liver of the specimens.

    PREVALENCE AND INTENSITY OF NEMATODE PARASITES OF Poecilia reticulata PETERS (1859) IN FOUR WASTEWATER DRAINS OF LAGOS STATE, NIGERIA BY MOHAMMAD-MONZOOR ADEWOLE, AKINWALE B.SC. (Sokoto), M. SC (Ibadan) A Dissertation in the Department of Zoology, Submitted to the Faculty of Science in partial fulfillment of the requirements for the Degree of MASTER OF PHILOSOPHY of the UNIVERSITY OF IBADAN FEBRUARY, 2013. ABSTRACT Poecilia reticulata (guppy) a common ornamental tropical fish is found in many wastewater drains in Nigeria. Guppies feed on copepods which are intermediate hosts of some nematode parasites of culturable fish species. The restriction on the importation of ornamental fishes into Nigeria has enhanced the demand for local species, usually sourced from the wild. There is dearth of information on the parasites of ornamental fishes in Nigeria. This study was aimed at determining prevalence and mean intensity of the nematode parasites of P. reticulata from four waste water drains in Lagos State. Sampling was carried out monthly using a 2 mm mesh-sized scoop net along selected drains at Igi-Olugbin Street (A), Basil Ogamba Street (B), Ahmadu Bello Road (C) and Adenaike Alagbe Street (D) between March, 2004 and February, 2005. The selected drains were contiguous to human habitation and industrial activities but each in different local government areas of Lagos State. Sixty female and sixty male samples were randomly selected from each drain for dissection and microscopy. Nematodes observed were identified using standard identification guides. Prevalence was determined as percentage infection in guppies examined. Intensity was determined as total parasite count per host. They were calculated in relation to sex of guppies and drain location for sample collection.

In principle, the disease name is constructed solely by the suffix -osis, which is added to the stem of the name of the parasite taxon, formed from the nominative of the taxa. Standardized nomenclature of animal parasitm diseases (SNOAPAD) is meant as a guideline for general use, to improve the clarity of scientific communication. It should be especially useful in promoting effective usage of computerized data retrieval services. INTRODUCTION Computerized data retrieval systems are of rapidly-growing importance and in the field of parasitology, the need for a uniform and proper terminology for use in these systems is being increasingly recognized.
