Alimentação e nutrição de Pirapitinga (Piaractus brachypomums) e Tambaqui (Colossoma macropomum): Revisão

Abstract

Brazilian aquaculture offers great diversity of native species with potential for cultivation due to the wide biodiversity of different river basins. Because of feeding costs and the importance of species Colossoma macropomum and Piaractus brachypomus for Brazilian aquaculture is essential knowledge of nutritional requirements and factors that may influence the development of balanced rations that allow adequate productive performance of Tambaqui and Pirapitinga. This study aimed to review research results related to nutrition Colossoma macropomum and Piaractus brachypomus. In the scientific literature, publications focus on determining the nutritional requirements of protein, energy and their relationships. They are scarce reviews aimed at determining the amino acid requirements; essential fatty acids, minerals and vitamins, since, for the most part, the diets practices provided to these species are formulated using certain requirements for exotic species. The digestibility of protein fractions and energy commonly used ingredients in feeding native fish should be better clarified. Even the possibility of inclusion of alternative food in the feeding of these fish should be evaluated, especially in species Piaractus brachypomus. Among the studied species it showed the greatest lack of information. We need to deepen the knowledge of the use of lipids and carbohydrates as energy sources, resulting in possible reduction of the protein level of feed. The appropriate levels of protein and energy rations are different, there is the need for standardization of the experiments.

Parasites in farmed Piaractus brachypomus (Serrasalmidae) in the state of Acre, western Brazilian Amazonia

“…In three of the fish farms, there were low levels of dissolved oxygen in the water, high stocking density of fish when compared to fish ACTA AMAZONICA farm 1, which favored the prevalence of parasites. In none of the farms the fish presented external signs of disease, which indicates the resistance to diseases of farmed P. brachypomus (Ribeiro et al 2016). Nevertheless, P. brachypomus of the four fish farms had a moderate infection level of parasites.…”

“…In Brazil, fish farming turned into an economic activity in the 1990s, with the emergence and dissemination of management technologies aimed at the cultivation of native species, and the first large-scale fish farms began the fattening of these fish (Kubitza 2007;Franceschini et al 2013). Currently, one of the farmed fish species with greatest potential in Brazil is Piaractus brachypomus Cuvier, 181 (Serrasalmidae), locally known as pirapitinga (Cruz et al 2006;Franceschini et al 2013;Ribeiro et al 2016;Saint-Paul 2017).…”

“…Piaractus brachypomus is the third largest scale fish from the Amazon basin, reaching up to 0.8 m in length and about 20 kg in weight. It presents attractive body characteristics for the consumer market, such as small head size, ease of flaking, as well as advantages for farming, such as rapid growth, resistance to high water temperatures and low levels of dissolved oxygen, and resistance to handling and diseases (Ribeiro et al 2016). The species is economically important and increasingly produced in fish farms in the state of Acre, VOL.…”

Occurrence, pathogenicity, and control of acanthocephalosis caused by Neoechinorhynchus buttnerae: A review

“…In Brazil, production from fish farming in 2018 was 722,560 tons, with 4.5% growth over the previous year. Tambaqui (Colossoma macropomum Cuvier, 1818) stood out as the main native species raised in captivity, and is produced in the main states of the northern, midwestern, and northeastern regions (Ribeiro et al, 2016;Peixe BR, 2019).…”
