Tratamento de efluente de aquicultura com macrófitas flutuantes: revisão sistêm...
Nogueira, Gabriele dos Santos; Bezerra, Gildete de Souza; Piana, Pitágoras AugustoA aquicultura é a produção de organismos que apresentam parcial ou total desenvolvimento na água, gerando um efluente rico em nutrientes. A utilização de alimentos artificiais é algo comum na produção aquícola, porém esses são altamente nutritivos em nitrogênio e fósforo. Tais nutrientes são fontes de energia para plantas aquáticas, como é o caso das macrófitas. O uso de macrófita para absorção de nutrientes é ...
Production of fish protein hydrolisates from Oreochromis niloticus fillet trimm...
Finkler, Joana Karin; Piana, Pitágoras Augusto; Fleck, Jéssica Fernanda; Boscolo, Wilson Rogério; Feiden, Aldi; Signor, Altevir; Fiorese, Monica LadyProcess optimization is essential for the large-scale viability of the food industry. Central composite rotational design (CCRD) followed by response surface analysis was used to optimize the production of fish protein hydrolysate (FHP). FHP was obtained from tilapia filet trimmings hydrolyzed subjected using Alcalase 2.4L™, Neutrase™, and Novo-Pro™ D enzymes under temperature, enzyme concentration, and pH-cont...

No. of bitstreams: 0 Previous issue date: 2014-01-01; This study was carried out to evaluate the morphometric characteristics, the yield and the centesimal composition of different cuts of the Barbadós (Pinirampus pirinampu) flesh, captured in the Itaipu Reservoir. Were used 55 animals randomly distributed into three classes of body weight [less than 620 g...
Egg transport and larval behavior of curimba, Prochilodus lineatus (Valencienne...
Queiroz, Thays Cristine Bellenzier de; Baumgartner, Dirceu; Piana, Pitágoras Augusto; Sanches, Paulo VanderleiLandscape changes and hydrologic alterations associated with dam construction have greatly hindered reproductive success and the recruitment of migratory species. However, little is known about the flow conditions that are necessary for the reproductive success of migrators. We aimed to analyze one of the important migrants of the Paraná River, the curimba, Prochilodus lineatus (Valenciennes, 1836), to determin...
Nitrogen and phosphorus dynamics in Nile tilapia farming in excavated rearing p...
Coldebella, Anderson; Godoy, Antonio Cesar; Gentelini, André Luis; Piana, Pitágoras Augusto; Coldebella, Priscila Ferri; Boscolo, Wilson RogérioThe purpose of this study was to determine the total nitrogen (TN) and total phosphorus (TP) balance during intensive tilapia farming in excavated ponds. To quantify TN and TP released into the environment, the supply water, effluents at the harvest time, fish composition, feed, and sediment were analysed. The mass balance between the amount of nutrients that is inserted through the feed, which is transformed i...

Piana, Pitágoras AugustoThe purpose of this dissertation was to construct predictive models based in panel data, a framework little considered in ecology. This analysis considers the functional relations between explanatory and response variables, controlling processes related to spatial and temporal dimensions of the data. It has the advantage over traditional methods employed in ecology because it allows the use of temporal data col...
