“…Higher levels of crude protein resulted in better use of the energy by fish. Mattos, Bueno, Honczaryk, Pereira-Filho, and Roubach (2018) reported that protein levels from 40 to 45% may provide a satisfactory growth to juveniles of matrinxã due to the positive influence on energy metabolism. The same authors also commented that, at this stage, matrinxã present a high demand for protein to meet its requirements of protein and energy.…”

The objective of the present study was to determine the apparent digestibility of juveniles of matrinxã Brycon amazonicus fed diets with different levels of protein. The experimental design was completely randomized, where the treatments consisted of four levels of protein in the diets (28, 32, 36 and 40%) and five replicates (water boxes) with 10 juveniles of matrinxã each. Diets were offered four times a day, and feces were collected twice a week, along 28 days, for digestibility analysis. Data collected were subjected to polynomial regression at 5% significance. Differences (p<0.05) were observed in dry matter digestibility, with higher digestibility according to increasing levels of protein in the diets. This behavior was directly expressed in the digestibility of nutrients by juveniles of matrinxã, such as % ash, % crude protein, apparent digestible energy, % digestibility of apparent digestible energy and energy: protein ratio. However, this was not observed (p > 0.05) in the digestibility of % ether extract. Digestibility of N, P, Ca, Mg, Cu and Zn presented linear positive (p < 0.05) behavior, in which the use of these minerals increased with the increase in the level of protein in the diets. However, the digestibility of K, Fe and Mn reduced (p < 0.05) with increasing protein levels in the diets. Thus, it can be concluded that the rise in protein level in diets for juveniles of matrinxã improves nutrient digestibility. The results of this study indicated that 40% crude protein in the diets provided better results.

“…que ocorre principalmente na Amazônia Central, costuma habitar as áreas alagadas e utiliza o canal do rio para sua migração (BENACON et al, 2015). A espécie tem hábito alimentar de caráter onívoro, no qual os juvenis preferem insetos e restos de animais ou plantas, já os adultos as frutas e sementes (MATTOS et al, 2018). Realizam uma migração trófica pela floresta alagada durante a enchente, época de reprodução e possui desova total (NAKAUTH et al, 2016).…”

“…This leads to lower feed consumption and productivity, as well as higher feed conversion. Mattos et al (2018) evaluated the effect of different levels of crude protein (30, 35, 40 and 45%) on juvenile matrinxã (approximately 3 g) in a continuous ow system. The study found no signi cant difference in the performance of the animals fed the three highest levels of crude protein in the diet.…”

This study evaluated potential for rearing the matrinxã, Brycon amazonicus, under different crude protein (CP) levels, using production performance, water quality and animal welfare as indicators. To achieve this, 720 juvenile fish (3.65 ± 0.17 g) were distributed across 24 experimental units (200 L) and fee study lasted 60 days. The study followed a factorial design (2x4), with two production systems: Biofloc technology (BFT) and clear water (CW), and four levels of crude protein (CP = 24%, 30%, 36%, and 42%) in the diet, with three repetitions for each. The study found that the BFT system showed a lower total ammonia level. However, the production system did not have any effect on pH or nitrite concentration. Oxygen levels were found to be lower in the 42% CP group. Fish produced in the BFT exhibited better performance of apparent feed conversion, productivity, and survival. The production system affected total leukocytes and neutrophils in the blood. There was no significant difference in carcass crude protein content and the ether extract content was higher in the animals from the BFT system. Nutritional composition of the biofloc showed differences for ash, with lower levels in the 42% CP treatment. In conclusion, juvenile matrinxã can be fed a diet containing 30% CP in both production systems. Furthermore, the results demonstrated that biofloc did not confer a direct benefit to matrinxã juveniles in terms of their feeding, however BFT represented a promising alternative for increasing the survival and improved animal welfare during the rearing phase.
