“…Colossoma macropomum (tambaqui) is a native Serrasalmidae of Amazon with a omnivorous natural diet (Soares et al, 2008), a characteristic that enables intensive rearing, since this species has substantial acceptance to meal (Chagas et al, 2005;Santos et al, 2013). Due to these features In Amazon, the tambaqui has been reared in ponds (Tavares-Dias et al, 2006;Delgado et al, 2011;Godoi et al, 2012) and net-cage (Morais et al, 2009;Santos et al;.…”

The aim of this study was to evaluate the parasites and parasite-host relationship in Colossoma macropomum from eight fish farms in Amapá State, Northern Brazil. A total of 12,242,559 parasites were recovered from hosts in the eight fish farms, and 87.4% of fish were infected by one or more parasite species, such as Ichthyophthirius multifiliis, Piscinoodinium pillulare, Trichodina sp. and Tetrahymena sp. (Protozoa), Anacanthorus spathulatus, Linguadactyloides brinkmanni, Mymarothecium boegeri and Notozothecium janauachensis (Monogenoidea), Procamallanus (Spirocamallanus) inopinatus (Nematoda) and Perulernaea gamitanae and Braga patagonica (Crustacea). Ichthyophthirius multifiliis presented dominance, but the greatest levels of parasitism were caused by I. multifiliis, P. pilulare, monogenoideans species and P. gamitanae, and all these parasites had an aggregate dispersion. The eight fish farms have differences in the parasitic infection levels, management and water quality, which are further discussed here.Keywords: Colossoma macropomum, metazoans, parasites, protozoans, sanity RESUMO O presente estudo avaliou as infecções parasitárias e a relação parasito-hospedeiro em

“…Similarly, increase in erythrocyte concentration is related to a greater oxygen demand in stress conditions (BRAUN et al, 2010), whereas variation in total plasma protein is an indicator of osmotic imbalance (WEDEMEYER, 1996). The values for glucose, hematocrit, and plasma proteins obtained for tambatinga were similar to those for tambaqui (BRANDÃO et al, 2004;CHAGAS et al, 2005;2007).…”

“…The productive performance of fish farming depends on the species, sex, stage of development and feeding management (Ng et al, 2000;Mihelakakis et al, 2002;Zuanon et al, 2004;Chagas et al, 2005). Moreover, management involves a number of meals, time of feed offer and feeding rate.…”

The main goal of modern intensive fish farms should be to increase productivity at a low cost. The automation of fish feeding plays an important role in this scenario since it may improve feed efficiency and reduce organic waste emissions. The aim of this experiment was to provide basic information for the development of feeding techniques using automatic feeders. The experiment was done from September to December, with tilapia weighing 185g, fed 48 meals a day at 22 or 30 minute intervals, with feeding rates of 2, 3 and 4% of live weight. Eighteen 1m 3 net cages equipped with automatic feeders were distributed in one pond. During the experimental trial the mean values for dissolved oxygen, pH and temperature were 3.20mg/l, 8.03 and 25.43°C, respectively. The highest average weight of 683.73g was achieved for fish treated with 4% of live weight at 30 minute intervals between meals. There was no difference for viscero-somatic index, demonstrating no alteration in the final carcass quality. These results demonstrate that a higher feeding rate added to efficient feed management can be used at the final stages of raising Nile tilapia in cages without compromising final fish productive quality.
