“…Entretanto, como, neste trabalho, os peixes receberam dietas com composição química semelhante (dietas isoenergéticas e isoproteicas), esta variação foi baixa, não havendo diferenças. Simões et al (2007) concluíram que filés de tilápia apresentam cerca de 19% de proteínas, 2,60% de lipídios e 1,09% de cinzas. Estes resultados diferem dos dados encontrados no atual experimento, porém, vale ressaltar que a composição centesimal A substituição de alimentos, como a de milho por triticale (Tachibana et al 2010) e de milho por farinha de manga (Melo et al 2012), ambas para a tilápia do Nilo, já foi estudada.…”

INTRODUÇÃOA criação de tilápias tem alcançado os mais altos índices de crescimento em águas continentais brasileiras e, embora existam diversas outras espécies com potencial para aquicultura (Godinho 2007), o grupo das tilápias chegou a alcançar mais de 155 mil toneladas, o que representa valores acima de 39% da produção brasileira (Brasil 2012).Tal fato é decorrente da capacidade que a espécie possui para se adaptar aos mais diversos lo- ABSTRACT RESUMOcais de cultivo e ao pacote tecnológico previamente estabelecido e da grande quantidade de ingredientes alimentares que esse peixe consegue utilizar em sua dieta, aproveitando muito bem alimentos de origem vegetal e animal. Por isto, diversos ingredientes alternativos são utilizados na ração (Boscolo et al. 2002, Neu et al. 2012, com a finalidade de reduzir custos e determinar um crescimento satisfatório, similar ao obtido com alimentos convencionais. Os alimentos orgânicos se distinguem dos demais por possuírem apelo agroecológico, pois são 1. Trabalho recebido em abr./2012 e aceito para publicação em nov./2012 (n° registro: PAT 18171).

“…Some authors (i.e. Souza, 2002;Souza et al, 2004;Boyd et al, 2007;Simões et al, 2007) has considered the FCR 1.8:1 as an acceptable rate in tilapia production. Thus, some estimates can be elaborated from applied indicators, for example, considering 1.8:1 as a reference value, during phase III and IV, where FCR was 2.14:1 and 2.21:1, respectively, had being left to supply 1.649 kg ha -1 of feed, which result in a reduction of 16% N and 15% P would enter the fishpond via feed, and of these about 9.53 kg ha -1 of N and 2.23 kg ha -1 of P would have being left to be released directly to the effluent.…”

“…Possibility of hormonal sex manipulation to obtain male populations, good acceptance of several types of food, great ability to harness natural foods in ponds, feed conversion ratio between 1.0:1 to 1.8:1 and the good growth in intensive cultivation, support intensive handling and low levels of dissolved oxygen in production and its high resistance to disease, besides its white flesh, firm texture, without thorns, slightly sharp taste and good acceptance (Souza, 2002;Souza et al, 2004;Simões et al, 2007).…”

Nitrogen and phosphorus flux from the production of Nile tilapia through the application of environmental indicators

et al. 2017

We aimed in this study utilize environmental indicators as a quantitative method to evaluate and discuss the nitrogen (TN) and phosphorus (TP) flux by a production stage grow-out (termination) of Nile tilapia (Oreochromis niloticus) in fishpond. The TN and TP load, the mass balance, the input of TN and TP via feed and the converted nutrients in fish biomass are the environmental indicators applied in this study. During the production cycle (128 days), the system exported 15,931 g TN and 4,189 g TP that were related to the amount of feed supplied (r Pearson = 0.8825 and r = 0.8523, respectively), corroborated by the feed conversion ratio (1.61:1). The indicators showed that 26% TN and 45% TP were reversed into fish biomass, 62% TN and 40% TP were retained in the fishpond, and 12% TN and 15% TP were exported via effluent. The largest contribution of nutrients generated by the system and exported via effluent was observed in phase III and IV. This result is supported by the feed conversion ratio 2.14 and 2.21:1 obtained at this phase, a fact explained by the amount of feed offered and the fish metabolism. Application of environmental indicators showed to be an efficient tool to quantify flux of TN and TP produced during the grow-out period of Nile tilapia and therefore, guide management practices more sustainable. Concerning the environmental sustainability of the activity the implementation of best management practices such as the better control of the feed amount offered would lead to a smaller loss of TN and TP to the water. Furthermore, the use of better quality feeds would allow greater nutrient assimilation efficiency.Keywords: environmentally sustainable management, nutrients load, mass balance, fish-farming, Oreochromis niloticus. Fluxo de nitrogênio e fósforo na produção de tilápia-do-nilo (Oreochromis niloticus) a partir da aplicação de indicadores ambientais ResumoNós objetivamos neste estudo, utilizar indicadores ambientais como método quantitativo para avaliar e discutir sobre o fluxo de nitrogênio (TN) e fósforo (TP) na etapa final de crescimento (terminação) de tilápia-do-nilo (Oreochromis niloticus) em viveiro escavado. A carga de TN e TP, o balanço de massa, a entrada de nutrientes via ração e o TN e TP convertido em biomassa de peixe foram os indicadores ambientais utilizados neste estudo. Durante o ciclo produtivo (128 dias), o sistema exportou 15.931 g NT e 4.189 g PT os quais foram relacionadas às quantidades de alimento fornecido (r Pearson = 0,8825 e r = 0,8523, respectivamente), corroborada pela conversão alimentar (1,61:1). Os indicadores evidenciaram que 26% NT e 45% PT foram revertidos em biomassa de peixe, 62% NT e 40% PT ficaram retidos no viveiro e 12% NT e 15% PT foram exportados via efluente. O maior aporte de nutrientes gerado pelo sistema e exportado via efluente foi verificado nas fases III e IV. Este resultado é corroborado pelas taxas de conversão alimentar de 2,14 e 2,21:1 obtida nestas fases, fato explicado pela quantidade de ração ofertada e pelo metabolismo dos peixe...

“…Farmed Tilapia production reached 95,091 tons whereas captured Tilapia accounted for 9,978 tons, in a total of 105,069 tons. Simões et al (2007) obtained Tilapia fillet yield values of 17.4% (skinless fillets) and 21.6% (fillet with skin) and the resulting waste products totaled 55.8% in average, its use being thus important. In such a context, with the use of mechanically deboned fish meat it becomes possible to make better use of fish resources and of many fresh water fish species, such as Nile Tilapia, which may be used as raw material in the production of minced fish and surimi, as well as other food products, which in turn may be employed in different food formulations.…”

In this study fishburger samples obtained from tilapia minced meat and surimi retrieved from fillet frames  filleting process waste  have been assessed. Four different preparations of fishburger were made. Chemical analyses was performed for protein, lipids, moisture and ash assessments, as well as bacteriological analyses through mesophilic aerobic heterotrophic and psychrotrophic bacteria counts, isolation and identification of Salmonella spp., coagulase-positive Staphylococcus and fecal coliforms. Instrumental measurements were also carried out for texture and tested sensory acceptance. The costs of the ingredients used in the preparation of formulas were also assessed. Microbiological standards, established by current regulations, were met by all samples. No significant gap (P>0.05) was detected among the percentage of protein, moisture and ashes, while a significant gap (P<0.05) was verified for lipids. A significant gap (P<0.05) for the instrumental measurements of texture was also observed. Both surimi and minced meat fishburger presented good acceptance on sensory tests for taste, texture and overall impression. The use of smoked fish flavoring and surimi caused a considerable increase in costs due to ingredient acquisition. This study shows a positive result for the industrialization and consumption potential of fishburgers made of minced fish retrieved from fillet frames.
