Seeds of sacha inchi (Plukenetia volubilis, Euphorbiaceae) as a feed ingredient for juvenile tambaqui, Colossoma macropomum, and matrinxã, Brycon amazonicus (Characidae) Acta Amazonica
ARAÚJO-DAIRIKI,Thyssia Bomfim; CHAVES,Francisco Célio Maia; DAIRIKI,Jony Koji.
ABSTRACT Sacha inchi (Plukenetia volubilis) is a plant native to the Peruvian Amazon with seeds that contain 24 to 29% protein, and levels of vitamin A and E and omega 3 polyunsaturated fatty acids that are suitable for fish nutrition. Thus, this study aimed to evaluate the use of sacha inchi seeds as an ingredient in the diets of tambaqui (Colossoma macropomum) and matrinxã (Brycon amazonicus). The acceptance and effect of three levels of sacha inchi seed meal (0, 15 and 30%) in fish feed was evaluated in a randomized experiment, testing groups of 12 juvenile tambaquis (29.8 ± 1.0 g, 11.0 ± 1.4 cm) and groups of eight juvenile matrinxãs (34.8 ± 1.3 g, 13.7 ± 1.0 cm). Growth performance and body composition of the fish were determined at the end of the...

Advantages of recovery from pre-slaughter stress in tambaqui Colossoma macropomum (Cuvier 1816) agroindustry in the Amazon Ciênc. Tecnol. Aliment.
MENDES,Joana Maia; DAIRIKI,Jony Koji; INOUE,Luis Antonio Kioshi Aoki; JESUS,Rogério Souza de.
Abstract Tambaqui is the main fish species farmed in the Amazon. It is produced on industrial scale, slaughtered in the field, primarily by post-harvest asphyxia. This procedure, however, is stressful because it depletes energy reserves that should be used in postmortem metabolism, which may compromise fish meat freshness and quality. The present study compared the quality of tambaquis slaughtered by asphyxia, the conventional industrial method, and hypothermia. Tambaquis weighing around 1.6 kg were harvested from dugout ponds, transported to experimental tanks and allowed to recover from transport stress for 48h. Biological parameters of fish were evaluated alive post- harvest (Harv), transport (Tr) and recovery (Rc), and postmortem analysis was performed...
