Among the animal protein production activities, world aquaculture has highest growth rate, and is mainly practiced in ground-excavated ponds. However, with great productivity comes concern about increasing generation of effluents, at moment fish removal, when high loads organic matter nutrients are released into environment. Thus, this study evaluated quality effluents through principal component analysis (PCA) samples from nurseries different sizes four sampling scenarios. Analysis was...
The purpose of this study was to determine the total nitrogen (TN) and phosphorus (TP) balance during intensive tilapia farming in excavated ponds. To quantify TN TP released into environment, supply water, effluents at harvest time, fish composition, feed, sediment were analysed. mass between amount nutrients that is inserted through which transformed biomass by retained calculated based on dry matter. nutrient load arriving from water as a function concentration TP. dynamics harvesting...
The objective of this research was to evaluate the production biomass aquatic macrophytes water hyacinth (Eichhornia crassipes) and egeria (Egeria densa) in three hydraulic detention times a organic pisciculture effluent treatment system. system composed for 18 experimental tanks 2.00 x 1.00 0.65m length, width depth respectively, coated with polypropylene canvas. An entirely randomized 2 3 (HDT) repetitions. HDT used 4, 8, 12 hours. evaluated at end experiment which extended 08/07...
The work aimed to evaluate the requirement of total phosphorus (Pt) for Nile tilapia. 125 fingerlings with average initial weight and length 0.95 ± 0.11 g 3.81 0.18 cm, respectively, were used. An entirely randomized design was used five treatments (0.4; 0.6; 0.8; 1.0; 1.2% Pt in ration) replications. final (FW), (FL), food conversion (FC) survival (SU) evaluated. best FW (W < 0.05) had been observed fish fed rations contend 1.0 Pt. FL ration 0.8% worst FC 0.4% Pt, lowest SU proportionate...
A ocorrência de compostos nitrogenados em água residuária abatedouro tilápia acima dos limites legais, tem causado sérios problemas poluição corpos d'água receptores. O processo biológico para remoção dessas substâncias comumente encontradas sob a forma nitrogênio amoniacal, é conhecido como nitrificação. Objetivou-se, com o presente trabalho, estudar efeito do tempo reação (TR) e da aeração na eficiência amoniacal conversão nitrato, abate um reator batelada sequencial biofilme. experimento...
O uso de macrófitas aquáticas pode ser uma alternativa para o tratamento e minimização dos efluentes gerados na piscicultura. Objetivou-se com este trabalho verificar a eficiência do aguapé (Eichhornia crassipes) melhora variáveis limnológicas (fósforo amônia) cultivo tambaqui (Colossoma macropomum) em canais fluxo contínuo água. experimento foi conduzido por um período 60 dias amostragens quinzenais abastecimento, seccionados telas utilizando densidade 120 peixes m-³. As seções foram...
125 fingerlings with initial weight of 3.25 ± 0.94 g and 6.29 0.63 cm length were used, distributed at an entirely randomized delineation in 25 aquariums capacity 35 L. The treatments consisted the milling ration ingredients mill bolters opening 0.50; 0.75; 1.00; 1.25 1.50 mm, respective average geometric diameter (DGM) 245.50, 317.23, 345.29, 366.04 450.28 µm. Differences (p < 0.05) not observed final length, weight, apparent alimentary conversion, profit daily tax protein efficiency...
A piscicultura em viveiros escavados na região oeste do Paraná se tornou uma atividade importante economia e muitas propriedades passou de atividades secundaria a principal renda. O crescimento segmento deve estruturação da cadeia produtiva com o demanda produção intensificação criação peixes ser prioridade, contudo, incremento exige uso acentuado sistemas aeração que devido variedade tipos aeradores condições adversas dos cultivo podem estar sendo utilizados forma inadequada. Diversas são...
Was determined economic viability of cultivation fingerlings the Nile tilapia (Oreochromis niloticus) in cages stocked at different densities. Between March and April 2011 an experiment was conducted a completely randomized design, with five treatments (500, 584, 667, 750 834 fish m-3) replications. Were evaluated variables: effective operational cost, total revenue, sales price, gross income, net financial income operating income. Based on low stocking density (500 to largest (834 m-3),...
