“…Shearer (1994) stated that centesimal composition can undergo endogenous and exogenous variations according to the genetics of the fish, the food they receive and the characteristics of their environment. These results differ from those obtained by Lui et al (2012), who analyzed different levels of inclusion of organic wheat in diets and did not observe changes in the chemical composition of the fish. However, the results corroborate with Souza et al (2013), who evaluated the impact of mango flour on the growth and body composition of Nile tilapia and observed a significantly lower percentage of ethereal extract in animals that received a diet of 100% mango flour.…”

The objectives of this work were to determine the apparent digestibility coefficients (ADC) of dry matter (DM), crude protein (CP) and gross energy (GE) of coconut biscuit residues (CBR), sweet biscuits (SBR) and noodles (NR) for Nile tilapia and evaluate the performance of fingerlings fed with diets containing the residues with the highest nutritional value. In the digestibility study, 72 juveniles (with an average weight of 70.5 ± 2.7 g) were organized in a completely randomized design with three treatments and three replications (12 fish per replication). ADC was determined using an indirect method in which 0.10% chromium oxide (Cr 2 O 3 ) acted as an indicator. To evaluate performance, 225 fingerlings (with an average weight of 3.4 ± 0.5 g) were distributed across 15 tanks (150 L), creating a completely randomized design with five treatments and three replications. The test diets contained 0, 4, 8, 12 or 16% CBR. ADCDM, ADCCP and ADCGE for each of the different residues were, respectively: 85, 88 and 86% for CBR; 32, 51 and 46% for SBR; 24, 31 and 26% for NR. The inclusion of CBR significantly affected final weight of the fish, specific growth rate and protein retention rate, as well as the carcass composition values for dry matter, mineral matter, gross energy and ethereal extract. CBR presents better digestibility than the other tested residues and it can be used as a substitute for maize meal in quantities up to 11.62%, thus improving fish performance.

ResumoObjetivou-se determinar os coeficientes de digestibilidade aparente da matéria seca (CDAMS), proteína bruta (CDAPB) e energia bruta (CDAEB) dos resíduos de biscoito de coco (RBC), biscoito doce (RBD) e macarrão (RM) para a tilápia-do-nilo e avaliar o desempenho destes alevinos alimentados com dietas contendo o resíduo com o maior valor nutritivo. No estudo de digestibilidade 72 juvenis (70,5±2,7g) foram distribuídos em um delineamento inteiramente casualizado com três tratamentos e três repetições (12 peixes por repetição). A determinação dos CDA foi realizada pelo método indireto, com a utilização de 0,10% de óxido crômico (Cr 2 O 3 ) como indicador. Para avaliação do desempenho 225 alevinos (3,4±0,5g) foram distribuídos em 15 tanques (150 L), compondo um delineamento inteiramente

“…Médias seguidas pela mesma letra em coluna não diferem entre si pelo teste de Tukey (P> 0,05).Quanto ao índice de gordura visceral (IGV), embora tenha ocorrido um pequeno acréscimo para o tratamento T3, não foi observada diferença significativa para nenhum dos tratamentos, ficando abaixo do observado por Lemoset al (2011) que utilizaram uma ração com farelo de coco em substituição ao farelo de sojaparao tambaqui, e superiores aos valores encontrados porLui et al (2012), que utilizaram trigo orgânico na dieta de tilápia. Por ser a tambatinga um peixe com tendência a acumular gordura visceral, característica de peixes redondos como o tambaqui, por exemplo, podemos considerar que no presente trabalho o índice de gordura visceral dos peixes alimentados com milheto foi baixo, porém semelhante ao índice para peixes alimentados com ração.A tabela 5 mostra os resultados para a composição bromatológica do filé de tambatinga nos diferentes tratamentos.…”

“…Organic aquaculture is still at the early stages in Brazil, however, in Paraná State, the development of tilapia culture based on agroecological standards was initiated a few years ago in a partnership between companies and producers who were familiar with this system . These producers were also interested in the verticalization of the production, from raw materials to animal production in an integrated manner and following agro-ecological principles (Lui et al, 2012). The organic farming system is geared towards the improvement of natural life cycles while preserving nature .…”

Aiming to assess organic soybean meal (OSM) for Nile tilapia, two studies were carried out: Study I - digestibility of OSM compared to conventional soybean meal (CSM) for Nile tilapia; and Study II - effect of OSM and CSM, supplemented or not with fish meal (FM) on the performance of Nile tilapia fingerlings. The apparent digestibility coefficients of the protein were 88.24 and 88.10%, resulting in 39.91 and 39.87% digestible protein for OSM and CSM, respectively. The apparent digestibility coefficients of energy were 75.92 and 70.48%, resulting in 3579.46 and 3141.44 kcal kg-1 of digestible energy for OSM and CSM, respectively. The diet containing CSM+FM presented the best results for final weight and weight gain. However, the highest levels of crude protein in the fish carcass were observed in the animals fed with the OSM + FM diet. The OSM diet presented the best results for total protein and albumin in the blood. The OSM diet has good apparent digestibility coefficients and its use in tilapia feeding presents a satisfactory productive performance and a higher deposition of protein in the carcass when supplemented with 20% of fish meal.
