“…Other nutrients such as the combination of linoleic fatty acids may reduce the total plasma triglycerides and cholesterol content in Colossoma macropomum (Souza, Santos, Bambirra, Viera, & Alvarez‐Leite, ). These dietary lipids did not alter triglycerides in Piaractus brachypomus ;however, the use of lard reduces cholesterol, while cod liver oil can lead to an increase (Vásquez‐Torres & Arias‐Castellanos, ). Protein concentrations between 24% and 34% in the diet of Takifugu obscurus do not alter triglycerides but reduce cholesterol (Liu et al, ).…”

Two experiments were conducted to assess the nutritional value and potential use of mesquite bean (Prosopis juliflora) meal (MBM) to substitute corn in extruded diets for Nile tilapia (Oreochromis niloticus). Digestible energy and the content of protein, soluble carbohydrates and amino acids were measured for 160 Nile tilapia juveniles (average weight 25.58 ± 5.52 g), allocated to eight treatment groups (four fed the experimental diet, and four fed a reference diet). To determine the inclusion potential of MBM, 384 fish (average weight 21.85 ± 1.01 g) were used and allocated to 24 tanks (1,000 L capacity). The experimental design was completely randomized with six levels of substitution (0%, 20%, 40%, 60%, 80% and 100%), and four repetitions. After the feeding experiment, tissue samples (blood, liver, muscle and intestine) were used to analyse metabolic and haematological variables. MBM produced apparent digestibility coefficients (ADC) similar to those of traditional diet ingredients: 81.85% dry matter (DM), 83.02% crude energy, 88.57% crude protein, 82.88% lysine and 82.57% methionine.Differences were observed in the digestibility of soluble carbohydrates (p < 0.05), with MBM having higher levels of starch (72.19%) and sucrose (88.99%). A 20% substitution with MBM produced a decrease in zootechnical performance (p < 0.05). Enzymatic activity of amylase and sucrose seemed to be induced in response to the proportion of their respective substrate in the diets. We observed a reduction in the efficiency of dietary protein utilization, with reduced levels of plasma amino acids (p < 0.05), owing to the increase in the enzymatic activity of muscular alanine and aspartate transaminases (ALT and AST) and the deaminase glutamate dehydrogenase in the hepatic and muscular tissues. Haematological variables did not indicate any adverse effects of MBM on the health status or survival of the fish (100%). Therefore, we conclude that MBM may be a viable alternative to corn meal in the diet, enabling substitution of up to 20%.

“…Although various aspects of P. brachypomus have been studied (Escobar et al ., 2015; Guimarães & Martins, 2015; Seshagiri et al ., 2022; Vásquez‐Torres & Arias‐Castellanos, 2013), our understanding of the ecology and early morphology of this species is limited. Piaractus brachypomus juveniles are abundant in the marginal stretches of the rivers, lakes and flooded areas of the Amazon region and use these environments for foraging and growth (Araújo‐Lima & Gomes, 2005; Santos et al ., 2009).…”

The initial development of the red-bellied pacu Piaractus brachypomus is described using morphological, meristic and morphometric characteristics. A total of 127 individuals were analysed (47 in the yolk-sac, 35 in pre-flexion, five in flexion, 20 in post-flexion and 20 in juvenile) with standard length varying between 2.92 and 48.61 mm. The larvae are born poorly developed and have a discoidal yolk at $6.33 mm standard length. During early ontogeny, the mouth passes from terminal to subterminal and the anal opening reaches the vertical line over the midline region of the body. There are changes in body shape from long and moderate to deep, head length from small to large, and eye diameter from moderate to large. Dendritic chromatophores were present in the ventral, dorsal and upper part of the swim bladder in the early larval stages. Rounded spots are evident all over the body in juveniles. The total number of myomeres ranges from 39 to 41 (20-23 pre-anal, 17-20 post-anal). Through the morphometric relationships, it was evidenced that the greatest changes during the initial ontogeny of P. brachypomus occur in the transition from the post-flexion stage to the juvenile period, indicating changes in behaviour, foraging and physiology.

“…Entre as espécies de peixes que tem suas exigências quantitativas determinadas para os dez aminoácidos essenciais (AAE), prevalece que todas elas são espécies exóticas, entre elas a carpa (Cyprinus carpio), tilápia do Nilo (Oreochromis niloticus), truta arco Íris (Oncorhynchus mykiss), bagre norte americano (Ictalurus punctactus) e salmão (Oncorhynchus spp.) (Vásquez-Torres & Arias-Castellanos, 2013). Neste sentido, a necessidade de desenvolver tecnologias que viabilizem a produção de espécies nativas tem levado os pesquisadores brasileiros a constantes estudos, especialmente em relação à alimentação e nutrição de peixes (Abimorad et al, 2007 especialmente Colossoma macropomum e Piaractus brachypomus, visto que este é um fator de grande influência no cultivo dessas espécies.…”

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.
