    PREVALENCE OF GASTROINTESTINAL PARASITES OF MONKEYS (ANTHROPOIDEA) AT PANDAM WILDLIFE PARK, PLATEAU STATE, NIGERIA.
    (Department of Zoology, Nasarawa State, University Keffi, 2008-01-06) Amuga, G.A.; Makpo, James Kpuk; Oniye, S.J.; Mohammed, S.G.
    A study to evaluate the prevalence of common gastrointestinal parasites of monkeys (Anthropoidea) at Pandam Wildlife Park, Plateau State, Nigeria zvas conducted betzveen April and August, 2006. Fifty-one faecal samples from three different locations at the park were collected and examined by formol-cther concentration method. Thirty-two of the samples were identified to be those of Tantalus Monkeys (Cercopithecus aethiops) while nineteen were for Baboons (Papio anubis). Forty seven of the samples constituting 92.2% were positive for intestinal parasites. Seven species of gastrointestinal parasites were encountered in the following proportions: Entamoeba histolytica (27.7%), hookworm (10.6%), Ascaris lumbricoides (17.0%), Enterobius vermicularis (4.3%), Physaloptera spp. (2.1%) and Strongyloides spp. (17.0%). Cases of mixed infections were those of E. histolytica and hookworm (4.3%), E. histolytica/S trongyloidcs (2.1%). The findings of this research show that intestinal parasites are endemic among Baboons and Tantalus Monkeys at Pandam Wildlife Park. The implications of this resultf orzvildlife conservation, ccotorism and fiational development are discussed

    Some Aspects of the Biology of Protopterus annectens (Owen) in Jachi Dam near Katsina, Katsina State, Nigeria
    (Department of Zoology, Nasarawa State, University Keffi, 2006-11-06) Oniye, S.J.; Adebote, D.A.; Usman, S.K.; Makpo, James Kpuk
    Some aspects of the biology of Protopterus annectens (Owen) were studied using 176 specimens purchased from fishermen in Jachi dam, near Katsina, northern Nigeria, from August to October 2005. The fish length ranged from 19.30 to 39.60 cm while the weight ranged from 13.0 to 420 g. The regression coefficient (b) was 3.17, indicating positive allometric growth pattern. The mean condition factor (k) was 0.47, but individual k-values ranged from 0.20 to 0.73. The pectoral-pelvic fins' length relationships showed high proportionate growth rate (b = 0.99). The correlation coefficient (r) of pectoral and pelvic fins relationships with total length of fish was 0.64 and 0.73, respectively. Analysis of the gut content showed that the fish consumed more plant material (86.81%) than insects (7.24%), molluscs (4.97%) and fish remains (0.97%).
