“…The intraperitoneal fat index was lower than that reported by and Signor et al (2010), although similar to that observed by Hilbig et al,(2012) for the pacu. Change in the intraperitoneal fat index occurred if fish required fat to obtain energy, a fact that occurred during long fasting (Hilbig et al, 2012).…”

“…Checking the above, Gomes (2008), who evaluating levels of organic selenium (0, 0.25, 0.50, 1.0, and 1.5 mg Se/kg) in the diet of tilapia (O. niloticus), reported no significant difference in the hepatosomatic index. For P. mesopotamicus with average weight of 377g, Hilbig et al (2012) found a 0.77% average hepatosomatic index, a lower rate than that in that in current assay, which averaged 2.75%.…”

Current study evaluates the supplementation of selenium and vitamin E in the diet on performance, body yields and lipid stability of pacu. Seven hundred and twenty juveniles were distributed in 36 cages installed in a masonry tank. During 100 days, the animals were fed on diets supplemented with four selenium levels (0, 1, 2 and 4 mg/kg), combined with three levels of vitamin E (0, 100 and 200 mg/kg) in a 4x3 factorial arrangement. Selenium combined with vitamin E levels did not affect (P>0.05) growth and body yield of pacu. The interaction between levels of selenium and vitamin E did not influence (P>0.05) the lipid stability of main trunks. When the levels of vitamin E only are evaluated, 200 mg vitamin E/kg diet decreases lipid oxidation in 90 and 120 days of storage. The combination of 0 Se + 0 vitamin E / kg diet was influenced by storage time, and the highest rate of lipid oxidation was observed with 120 days of storage. Level 1 mg selenium + 200 mg vitamin E/kg in the diet of the pacu decreased meat lipid oxidation after 90 days of storage under freezing, coupled to the maintenance of performance and body yields.

“…Hilbig et al (2012), ao avaliar a taxa 100, 90, 80 e 70% da quantidade do arraçoamento à vontade de alimentação de pacu em tanques-rede, não observaram diferença nas variáveis bioquímicas; os valores obtidos no presente trabalho também foram semelhantes quanto aos triglicerídeos e às proteínas totais, e menores quanto à glicose e ao colesterol.…”

O objetivo deste trabalho foi avaliar o desempenho zootécnico e as características bromatológicas e hematológicas de pacus alimentados a diferentes frequências de arraçoamento. Três mil e duzentos peixes, com peso inicial médio de 65,9±2,36 g, foram distribuídos em 16 tanques-rede de 5 m³ de volume útil. Durante 65 dias, foram avaliadas quatro frequências de arraçoamento (tratamentos): T1, às 12:00 h; T2, às 8:00 e às 17:00 h; T3, às 8:00, 12:00 e 17:00 h; e T4, às 8:00, 11:00, 14:00 e 17:00 h. Utilizou-se o delineamento experimental inteiramente casualizado, com quatro repetições. Analisaram-se parâmetros de desempenho produtivo, índices de gordura visceral e hepatossomático, composição centesimal da carcaça e parâmetros hematológicos e bioquímicos. Quanto ao ganho de peso, as frequências T3 e T4 proporcionaram melhores resultados do que T1 e T2. Embora a proteína, o colesterol e os eritrócitos tenham apresentado diferenças entre os tratamentos, permaneceram dentro dos valores de referência para pacus cultivados em tanques-rede. A frequência de três arraçoamentos diários resultou em maior ganho de peso, em comparação aos demais tratamentos, sem interferir na saúde e na composição centesimal das carcaças dos animais.

The South American continent is known for its high production and exports in fisheries and aquaculture, but has not reached its full potential in fish farming. The latest data on fish production in Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Peru, Uruguay and Venezuela were explored in this review. Aspects of biology, production, market and health of the species most produced in South America are described in detail. These species include the round fish (Colossoma spp., Piaractus spp. and hybrids) and catfish (Pseudoplatystoma spp. and hybrids), in addition to the promising pirarucu Arapaima gigas, yellowtail tetra Astyanax altiparanae and silver catfish Rhamdia quelen. Among the countries mentioned, Chile and Brazil are two of the largest intensive fish producers in the world. Chile relies primarily on marine fish, whereas Brazil is prominent for continental production. Special emphasis is given to the black pacu Colossoma macropomum because it is a commonly farmed fish in South American countries and offers several desirable productive characteristics (domesticated, omnivorous and easy to reproduce). Furthermore, this fish has the greatest potential to compete economically with tilapia production in South America. The production of native fish is currently overtaking the production of exotic species in some countries, which is considered a milestone for South American aquaculture. Regarding diseases, the main pathogens are similar to those observed throughout the world, such as Ichthyophthirius multifiliis, different species of monogeneans and trichodinids, and the bacteria Aeromonas hydrophila. Local pathogens, such as the parasites Perulernaea gamitanae and Goezia spinulosa, are also concerning.
