A piscicultura e o ambiente: o uso de alimentos ambientalmente corretos em piscicultura
Provedor de dados: 96
Autores: Cyrino,José Eurico Possebon; Bicudo,Álvaro José de Almeida; Sado,Ricardo Yuji; Borghesi,Ricardo; Dairik,Jony Koji.
Embora a ciência da nutrição de peixes esteja longe de estabelecer um padrão geral de exigências nutricionais, a necessidade de desenvolvimento de alimentos de baixo impacto poluente há muito faz parte da agenda das comunidades científica e empresarial internacional da aqüicultura. Não só é absolutamente possível formular alimentos ambientalmente corretos, como é necessário modelar a formulação destes alimentos. Porém, é necessária absoluta acurácia para atender formulações espécie-específicas, considerando-se as interações da biologia e fisiologia nutricional das espécies com os alimentos e com as variações abióticas do meio. O conhecimento disponível sobre as mais de 200 espécies de peixe produzidas comercialmente no mundo é ainda incipiente e os...

Apparent digestibility of ingredients in diets for Salminus brasiliensis
Provedor de dados: 86
Autores: Braga,Luís Gustavo Tavares; Borghesi,Ricardo; Cyrino,José Eurico Possebon.
The objective of this work was to determine the nutritional value of different protein sources for "dourado" (Salminus brasiliensis). Thirty juveniles per group (33.51±1.4 g) were hand fed on a reference diet (70%) added of tested ingredients (30%) and chromium oxide III (0.1%). Apparent digestibility coefficients of the gross energy (ADC GE), crude protein (ADC CP) and amino acids of the tested ingredients were evaluated. Corn gluten meal yielded the best results for ADC GE and ADC CP (95.7 and 96.9%, respectively) amongst plant ingredients. Spray-dried blood meal yielded the best values of ADC GE and ADC CP amongst animal ingredients (94.1 and 96.3%, respectively). Wheat bran yielded poorest ADCs coefficients (77 for ADC GE and 88.2% for ADC CP).

Fish silage in black bass (Micropterus Salmoides) feed as an alternative to fish meal
Provedor de dados: 52
Autores: Arruda,Lia Ferraz de; Borghesi,Ricardo; Portz,Leandro; Cyrino,José Eurico Possebon; Oetterer,Marília.
The objective of this study was to use the residues of fermented sardine to elaborate the acid fish silage and its use in feed for aquaculture. Biological assay was performed by feeding largemouth bass (Micropterus salmoides) fingerlings (initial weight 22g), with extruded diets (41% crude protein; 3,600 kcal/kg digestible energy) containing 0.0, 7.5, 10.0, 12.5, or 15.0% of fish silage in partial substitution to the fish meal. The feed conversion ratio and weight gain for the treatments were: 1.26 and 15.76g; 1.11 and 17.07g; 1.19 and 17.81g; 1.18 and 19.83g; 1.47 and 14.64g, respectively. No significant differences (P&lt;0.05) were detected among the treatments. Results indicated that it was possible to use up to 15% of acid fish silage as partial...

Lysine and arginine requirements of Salminus brasiliensis
Provedor de dados: 86
Autores: Dairiki,Jony Koji; Borghesi,Ricardo; Dias,Carlos Tadeu dos Santos; Cyrino,José Eurico Possebon.
The objective of this work was to determine the dietary lysine (DL) and dietary arginine (DA) requirements of dourado (Salminus brasiliensis), through dose-response trials using the amino acid profiles of whole carcasses as a reference. Two experiments were carried out in a completely randomized design (n=4). In the first experiment, groups of 12 feed-conditioned dourado juveniles (11.4±0.2 g) were stocked in 60 L cages placed in 300 L plastic indoor tanks in a closed circulation system. Fish were fed for 60 days on diets containing 1.0, 1.5, 2.0, 2.5, 3.0, or 3.5 % dietary lysine. In the second experiment, dourado juveniles (27.0±0.8 g) were fed for 60 days on semipurified diets containing arginine at 1.0, 1.5, 2.0, 2.5 or 3.0%, in similar conditions to...

Monitoring the sardine (Sardinella brasiliensis) fermentation process to obtain anchovies
Provedor de dados: 63
Autores: Oetterer,Marília; Perujo,Sérgio Daniel; Gallo,Cláudio Rosa; Arruda,Lia Ferraz de; Borghesi,Ricardo; Cruz,Ana Maria Paschoal da.
Anchovies are traditional fish preserves, prepared from fermented fish of the engraulidae family, mainly in European countries. In Brazil, sardines (Sardinella brasiliensis) are an alternative fish for preparing these types of preserves, provided that the preservation process results in a high quality product. In this research, sardines were prepared for preservation and physicochemical, microbiological and sensory analyses were carried out during the preservation process. Whole or eviscerated sardines, with or without condiments/preservatives and with 20% of salt (w/w) were used. Sardines were analyzed fresh, and at 1, 15, 30, 45 and 60 days along the preservation process. The use of whole sardines, with or without condiments/preservatives, presented best...

Performance of juveniles of Pseudoplatystoma fasciatum fed graded levels of corn gluten meal
Provedor de dados: 86
Autores: Bicudo,Álvaro José de Almeida; Borghesi,Ricardo; Dairiki,Jony Koji; Sado,Ricardo Yuji; Cyrino,José Eurico Possebon.
The objective of this work was to evaluate corn gluten meal (CGM) as a substitute for fish meal in diets for striped catfish (Pseudoplatystoma fasciatum) juveniles. Eight isonitrogenous (46% crude protein) and isoenergetic (3,450 kcal kg-1 digestible energy) diets, with increasing levels of CGM - 0, 6, 12, 18, 24, 30, 36, and 42% -, were fed to juvenile striped catfish (113.56±5.10 g) for seven weeks. Maximum values for weight gain, specific growth rate, protein efficiency ratio and feed conversion ratio, evaluated by polynomial quadratic regression, were observed with 10.4, 11.4, 15.4 and 15% of CGM inclusion, respectively. Feed intake decreased significantly from 0.8% CGM. Mesenteric fat index and body gross energy decreased linearly with increasing...

Trânsito gastrintestinal de dieta seca em Salminus brasiliensis
Provedor de dados: 86
Autores: Braga,Luís Gustavo Tavares; Borghesi,Ricardo; Dairiki,Jony Kojy; Cyrino,José Eurico Possebon.
O objetivo deste trabalho foi avaliar tempo de passagem do alimento e seqüência de repleção e depleção dos órgãos no trato gastrintestinal de Salminus brasiliensis. Cem peixes (38,8±7,6 g) foram mantidos em 20 gaiolas (60 L), a 24,8±0,2ºC e alimentados com ração contendo 1% de Cr2O3. A cada 60 min a partir da primeira alimentação foram sacrificados cinco peixes e foi verificada a localização da digesta no trato gastrintestinal. A partir da segunda hora depois da alimentação, observou-se redução gradativa do conteúdo estomacal e subseqüente presença de digesta no intestino. Esse padrão se mantém até a 16ª hora; uma e duas horas depois, estômagos e intestinos, respectivamente, encontram-se completamente vazios.

Use of fish waste as silage: a review
Provedor de dados: 52
Autores: Arruda,Lia Ferraz de; Borghesi,Ricardo; Oetterer,Marília.
The use of fish silage as a substitute for protein ingredients in rations for aquatic organisms is an alternative to solve sanitary and environmental problems caused by the lack of adequate disposition for the waste from the fish industry. Besides, it is also a way of decreasing feeding costs, and, consequently, fish production costs, since feeding corresponds to about 60% of the overall expenses with production. The objective of this review was to discuss the use of fish waste, the elaboration of chemical silage and the use of this ingredient in feed for aquaculture.
