This study investigated the diversity of metazoan parasites in Colossoma macropomum from the Jari River, in the eastern Amazon, northern Brazil. We collected a total of 4966 parasites from 34 fishes, including monogeneans (Anacanthorus spathulatus, Mymarothecium boegeri, Notozothecium janauachensis and Linguadactyloides brinkmanni), nematodes (Spectatus spectatus larvae, Contracaecum sp. larvae andProcamallanus (Spirocamallanus) inopinatus), digeneans (Cladorchiidae metacercariae), acanthocephalans (Neoechinorhynchus buttnerae), crustaceans (Ergasilus turucuyus, Argulus multicolor, Perulernaea gamitanae and Braga patagonica), mites and leeches. The dominance was of monogenean species, found in the gills of the hosts. The parasites exhibited high aggregate dispersion, except Contracaecum sp. and P. (S.) inopinatus that showed uniform and random dispersion, respectively. The species richness of parasites varied from 1 to 9, the Brillouin diversity index from 0 to 1.52, evenness from 0 to 0.63 and the Berger-Parker dominance index from 0.39 to 1.00. Abundance of parasites was not influenced by host length, but there was significant correlation with host body weight in some cases. The parasite community was characterized by low species richness and moderate diversity, with a predominance of ectoparasites with high prevalence and abundance, as well as the presence of endoparasites in the larval stage. |

When associated an adequate shading and nutrition the seedlings to reach characteristics that allow them to survive in the field and increase production. Thus, this work aimed to evaluate the production of Oenocarpus bataua seedlings in response to different shade environments and controlled-release fertilizer doses. The study was carried out from at the Embrapa nursery located in the municipality of Rio Branco, Acre state. The experimental design was complete randomized blocks with three replications and six plants per plot. The treatments were distributed according to a 4 x 5 factorial scheme, i.e., four shade environments (20%, 30%, 50% and 75%) and five CRF doses (0.0, 1.5, 3.0, 4.5 and 6.0 kg m?3) mixed with the substrate. Biometric, biomass and quality variables were evaluated at 305 days after transplanting. The ANOVA was applied for the qualitative factor and regression analysis was performed for the quantitative factor, both at 5% probability. The treatments were grouped by analyzing canonical variables, a multivariate statistical and realized the Pearson's correlation between variables was determined through correlation networks. The shading environment and the controlled-release fertilizer positively influenced the growth and quality of Oenocarpus bataua seedlings. The seedlings of Oenocarpus bataua have better biometric characteristics produced in a nursery with 50% shading. Oenocarpus bataua seedlings show better quality when 3.88 kg m-3 of controlled release fertilizer are used.
