“…Our results showed that EOAT did not influence taste or odour in fillet. This was also observed for the essential oil of L. alba (300 mg L À1 ) in silver catfish (Cunha, Barros et al 2010) and Nile tilapia (Hohlenwerger et al 2016), but not for eugenol (50 lL L À1 ) in silver catfish (Cunha, Zeppenfeld et al 2010).…”

“…Blood samples were collected from eight fish from the first tank one hour after anaesthesia and from another eight fish from the second tank four hours after anaesthesia. The control group was subjected to the same procedures as the test group, but without the addition of EOAT (adapted from Cunha, Barros et al 2010;Cunha, Zeppenfeld et al 2010;Hohlenwerger et al 2016).…”

The optimum concentration of anaesthetic used to facilitate fish handling can be determined based on induction and recovery time, among other factors. This study aimed to evaluate the effectiveness of the essential oil of Aloysia triphylla (EOAT) as an anaesthetic in the handling of Nile tilapia juveniles. Nile tilapias exemplars were immersed at 0 (control group), 10, 20, 30, 40, 80, 150, 300 and 450 μL L−1 EOAT to evaluate sedation, anaesthesia and recovery time. The stress response was evaluated by the determination of plasma glucose, cortisol, lactate and paraoxonase levels in anaesthetized (300 μL L−1 EOAT) and non‐anaesthetized fish. Fillets from both groups were evaluated for organoleptic characteristics (taste and odour). Concentrations of 80–450 μL L−1 EOAT were effective in inducing anaesthesia. There was a significant reduction in plasma cortisol levels one hour after handling in individuals anaesthetized with 300 μL L−1 EOAT compared to the control group. Tasters did not detect differences in fillet taste and odour between fish exposed and not exposed to EOAT. A concentration of 300 μL L−1 EOAT is recommended for handling Nile tilapia because it presents good anaesthetic induction and recovery times, causes a reduction in plasma cortisol levels one hour after handling and does not affect the taste or odour of the fillets.

“…Ao final do período experimental, os peixes foram submetidos a jejum de 24 horas, anestesiados com eugenol (solução de óleo de cravo, a 50 mg L -1 ) (Cunha et al, 2010), e foram, então, pesados e medidos (Certificado de Apresentação para Apreciação Ética nº 006973/2009-41).…”

Resumo -O objetivo deste trabalho foi avaliar o efeito de diferentes densidades de estocagem e frequências alimentares sobre a resposta zootécnica e metabólica, e sobre a composição de peixe inteiro e de filé de juvenis de jundiá (Rhamdia quelen) cultivados em tanques-rede durante 60 dias. Foram utilizados 1.200 juvenis de jundiá (57,48±3,34 g e 17,86±0,36 cm). Os peixes foram distribuídos em delineamento inteiramente casualizado, em arranjo fatorial 2×2, à densidade de 50 e 150 peixes m -3 e frequência alimentar de uma ou duas vezes ao dia. Tanto as densidades de estocagem quanto o manejo alimentar não influenciaram o desempenho nem os parâmetros metabólicos. No entanto, a interação entre a menor densidade e a maior frequência alimentar resultou em menor teor lipídico nos filés. Como ambos os fatores testados não interferiram no desempenho zootécnico, pode-se sugerir como melhor densidade a de 150 peixes m -³, com frequência de arraçoamento de uma vez ao dia.Termos para indexação: Rhamdia quelen, manejo alimentar, parâmetros metabólicos, qualidade de pescado. Stocking density and feeding rate of South American catfish reared in net cagesAbstract -The objective of this work was to evaluate the effect of different stocking densities and feeding frequencies on the zootechnical and metabolic response and on the whole fish and fillet composition of juvenile South American catfish (Rhamdia quelen) cultured in net cages for 60 days. One thousand and two hundred juvenile catfish (57,48±3,34 g and 17,86±0,36 cm) were used. Fish were distributed in a completely randomized design, with a 2×2 factorial arrangement, at 50 and 150 fish m -3 and feeding frequency once or twice a day. Both stocking density and feeding influenced neither the performance, nor the metabolic parameters. However, the interaction between the lowest density and the highest feeding frequency resulted in the lowest lipid content in the fillets. As both tested factors did not affect the growth performance, 150 fish m -3 can be suggested as the best density together with a once-a-day feeding frequency.

“…Para amenizar o estresse provocado pelo manejo nas biometrias e facilitar o manuseio dos animais, foi utilizado o anestésico eugenol na proporção de 0,05ml litro -1 de água (CUNHA et al, 2010). A coleta de sangue e tecidos (fígado, estômago e intestino) foi realizada na oitava semana de experimento.…”

RESUMO O objetivo deste estudo foi analisar a influência da adição de farinha de resíduos de jundiá (Rhamdia quelen) na dieta de exemplares desta espécie sobre a bioquímica plasmática, parâmetros hepáticos e digestivos. No experimento I (EXP I), compararam-se dietas com 30% de farinha de carne e ossos suína (FCO), farinha de carcaça de jundiás com vísceras (FCJCV), farinha de carcaça de jundiá sem vísceras (FCJSV) e farinha de jundiás inteiros (FJI). No experimento II (EXP II), níveis de inclusão de FCJCV foram testados (0; 3,75; 7,5; 15 e 30%) ABSTRACT The objective of this study was to analyze the influence of the addition of jundiá (Rhamdia quelen) waste meal in the diet of this species, on plasmatic biochemistry, liver and digestive parameters. Experiment I (EXP I) compared diets with 30% of meat and swine bones (FCO), Jundiá carcass meal with viscera (FCJCV), Jundiá carcass meal without viscera (FCJSV) and full Jundiá meal (FJI). In experiment II (EXP II), different FCJCV levels were tested (0, 3.75, 7.5, 15, and 30%
