    ABSTRACT: In the period of October 2007 to August 2008, 152 specimens of Pygocentrus nattereri were caught in the Negro River in the Nhecolândia region, central Pantanal wetland, State of Mato Grosso do Sul, Brazil. The specimens were necropsied and a total of 4,212 metazoan endoparasites were recovered, belonging to 10 taxons: Procamallanus (Spirocamallanus) inopinatus, Philometridae gen. sp., Eustrongylides sp., Brevimulticaecum sp., Contracaecum sp. (Nematoda), Echinorhynchus paranensis (Acanthocephala), Leiperia gracile, Sebekia oxycephala, Subtriquetra sp. 1 and Subtriquetra sp. 2 (Pentastomida). This is the first record of two parasite species from P. nattereri: E. paranensis and L. gracile.

    ABSTRACT: This study defined some population parameters for growth of the Red-bellied Piranha (Pygocentrus nattereri) in the Pantanal, based on the bimonthly length-frequency distribution of individuals in samples taken from October 2005 through August 2008 in the Negro River. The samples were taken by means of gill nets and cast nets, with meshes of 1.5–8 cm between adjacent knots. The standard length of the fish ranged from 10.2 to 30.2 cm with a mean of 20.51 ± 3.39. The gonadosomatic index (GSI) varied significantly among months (F = 5.45; p < 0.01), it was significantly higher from October to February, and was positively correlated and synchronized with day length (rs = 0.92; p < 0.01) and rainfall (rs = 0.70; p < 0.01). It was desynchronized from and not correlated with river level (rs = 0.12; p = 0.69). The GSI reached the highest values and ripe individuals were more frequent in December, prior to the months of highest river levels from February to April. The estimated growth parameters were L∞ = 31.8; k = 0.45; Rn = 0.204. In the Pantanal, P. nattereri has a life expectancy (6.9 years) compatible with the 7 cohorts indicated by the growth curve. Sexual maturation occurred at around 15.4 cm, after 1.6 years.

    ABSTRACT: In order to inventory the metazoan endoparasites of Serrasalmus marginatus, 91 specimens were examined. They were captured in the Negro River in Pantanal wetland, State of Mato Grosso do Sul, Central-Western Brazil, from October 2007 to August 2008. Parasites of six taxa were recovered: Procamallanus (Spirocamallanus) inopinatus, Contracaecum sp. (Nematoda), metacercarial type Diplostomulum (Digenea), Brevimulticaecum sp. (Nematoda) and Sebekia oxycephala, Subtriquetra sp. 1 and Subtriquetra sp. 2 (Pentastomida). The latter five species are reported for the first time in S. marginatus.
