“…In this way, the results of the present research also suggest that the protein requirements of the hybrid tambatinga are lower than those estimated for C. macropomum juveniles (280–480 g/kg CP) and P. brachypomus (316 g/kg CP), as reported, respectively, by Guimarães and Martins () and Vásquez‐Torres, Pereira‐Filho, and Arias‐Castellanos (). Additionally, the digestible protein (DP) requirement of tambaqui was estimated at 290 g/kg (equivalent to 330 g kg of CP) by Buzollo et al ().…”

This research assessed four levels of crude protein—200, 250, 300 and 350 g/kg—associated with two crude lipid concentrations—110 and 140 g/kg—in diets for juveniles of tambatinga (♀Colossoma macropomum × ♂Piaractus brachypomus) over 63 days. The fish (15.2 ± 0.2 g) were distributed in 24–160 L tanks (11 fish/tank) in a 4 × 2 completely randomized factorial design (n = 3). Increasing the lipid content in the diets reduced (p < 0.05) the protein requirements for weight gain from 326 g/kg (diets with 110 g/kg LIP) to 255 g/kg (diets with 140 g/kg). Protein retention in the fish increased (p < 0.05) when they were fed up to 293 g/kg CP and 140 g/kg LIP; in the diets with 110 g/kg LIP, protein retention decreased linearly (p < 0.05) as the protein content in the diets increased. Feed efficiency increased (p < 0.05) when the fish received up to 308 g/kg CP regardless of lipid concentration (p > 0.05). In conclusion, tambatinga juveniles at 15–120 g have a minimum requirement of 255 g/kg CP and 140 g/kg CL and a protein:energy ratio of 17.4 g CP kJ/digestible energy (DE).

“…Specularis and optimum protein requirement level was found to be 41.5% for the best growth and feed utilization. Optimum dietary protein requirements were found to be 31.6% for juvenile cachama Piaractus brachypomus (Vásquez‐Torres, Pereira‐Filho, & Arias‐Castellanos, ), 40% for Thai Strain of Climbing Perch, Anabas testudineus (Hossain, Sultana, Kibria, & Azimuddi, ) and 35% for Blue Streak Hap, Labidochromis caeruleus (Ergün et al, ).…”

An experiment was designed to evaluate the requirement of dietary protein for Reba carp, Cirrhinus reba fingerlings using semi‐purified diet. Five isocaloric diets were prepared containing 20%, 25%, 30%, 35% and 40% level of protein using casein, gelatin as a major protein source. The experiment was conducted for 105 days in triplicates to evaluate the growth, survival, feed utilization, carcass composition of C. reba. Mean weight gain was highest (p < .05) in T3. Specific growth rate was highest in T3 and lowest in T1. Similarly, significantly (p < .05) highest net fish yield were recorded in T3. No significant difference was recorded in survivability. Feed conversion ratio, protein efficiency ratio, feed conversion efficiency and protein conversion efficiency were significantly (p < .05) higher for T3 compared with other treatments. Highest carcass protein and lipid values were recorded in T3. So, conclusion can be drawn that 30% crude protein is optimum for overall performance. Furthermore, broken‐line analysis for specific growth rate, final biomass and net fish yield indicated that dietary protein level of 28.148 to 28.253% is optimum for the best growth performance of fingerling C. reba.

“…P. brachypomus is an omnivorous fish that usually feeds on leaves, fruits, small fish and crustaceans in their natural habitat. Knowledge on their nutritional requirement and feeding is very limited; however, the protein requirement is reported to be circa 320 g kg −1 , while lipid and carbohydrate levels are within 40–60 and above 360 g kg −1 , respectively (Vásquez‐Torres et al., ) (Table ).…”

This short review will focus on the nutritional requirement of tambaqui (Colossoma macropomum) and pirapitinga (Piaractus brachypomus), two important aquacultured neotropical fishes for Latin American countries. Demonstrated is that despite the large number of studies on protein requirement for C. macropomum, most are inadequate. The principal difficulties with the various published papers are described. Using the nutritional ecology of the fish, some recommendations are presented to identify future research needs in the area. A focus on determining the nutrient requirement for P. brachypomus is featured since there are few studies regarding this species, as well as a focus on the differences in feeding plasticity with C. macropomum. Market and farming constraints and the nutritional ecology of these species in Latin America with special emphasis on Brazil, are also described.
