“…However, Salaro et al (2008) found a feeding rate for trairao (Hoplias lacerdae) juveniles of 4.0%, which promoted higher weight gain, when compared with 2.0 and 6.0%; the latter achieved the worst daily weight gain rates and consequently, the worst feed conversion.…”

-The objective of this study was to evaluate the feeding management of pacu juveniles (P. mesopotamicus) under different feeding rates and its relation with productive performance, body composition and hematological characteristics.A total of 300 fish with initial weight of 84.75±4.52 g were distributed in a completely randomized design composed of four treatments (100, 90, 80 and 70% of feed supply) and five repetitions. The amount of feed was stipulated according to the quantity supplied in the treatment until apparent satiation (100%) of the day before. The decrease in the feeding rate to 70% over satiation apparently improves the apparent feed conversion without harming performance, body composition or biochemical and hematological characteristics of pacu juveniles reared in net cages.Key Word: amount of feed, feeding management, intensive aquaculture, native species Revista Brasileira de Zootecnia

“…L. alexandri juveniles demonstrated a survival ranging from 93 to 100% at feeding rates of 2 and 8%, respectively, showing that the juveniles were efficiently trained to eat the dry diet. A high survival rate was also found for another benthonic carnivorous fish, the giant trahira, fed at feeding rates of 2, 4 and 6% of the body wet weight per day (Salaro, Luz, Sakabe, Kasai & Lambertecci ). These results showed the efficiency of feed training for benthonic carnivorous freshwater species.…”

This study evaluated the efficiency of the drainage system during the larviculture of Lophiosilurus alexandri. Moreover, we assessed the best feeding rate after feed training for juvenile production. The study was performed in three phases over 87 days. In phase 1 (40 days), larvae were fed live food and posteriorly submitted to feed training in two drainage systems: water drained on the surface (DS), and water drained into a tank column (DI). In the second phase (30 days), using only the DS system juveniles were fed a formulated diet at feeding rates, 2, 4, 6 and 8% of body wet weight. In the third phase (17 days), the fish from the second phase were fed until apparent satiation. At the first phase, the animals in the DS system exhibited greater survival rates and growth. The best feeding rate for daily weight gain, specific growth rate (SGR) and mean body weights were similar: 5.57, 5.13 and 5.68% respectively. In the third phase, an increased SGR was observed in the treatment groups that received lower feeding rates in the second phase (2 and 4%), which could indicate a possible compensatory growth rate.

“…On the other hand, studies indicated that increasing feeding levels present a linear effect to weight gain and specific growth rate to Odontesthes argentinensis (Tesser and Sampaio, 2006) and no effects to weight gain and length to trairão (Hoplias lacerdae) (Salaro et al 2008). Meurer et al (2005) suggested that the quadratic effect to performance parameters of fingerlings can be explained, due to the fact that lower feeding levels no provided adequate intake of nutrient levels for the expression of the maximum fingerling growth.…”

The present work is aimed to determine the best feeding level to pacamã (Lophiosilurus alexandri) fingerlings at performance, survival, and body parameters. One hundred One hundred and twenty five fingerlings with mean body weight of 3.57±0.05g were used and distributed in a completely randomized design with five treatments and four replicates during 30 days. The treatments were five feeding levels: 3, 6, 9, 12, and 15% of body weight day-1 of to pacamã fingerlings fish, were feeding twice times daily, 08h00 and 18h00. The diet contained 57,28% crude protein and 3.405,98 Kcal kg-1 gross energy. Water temperature ranging of 27.3°C to 28.6°C, and dissolved oxygen was 5.0 mg/L. A quadratic effect (P<0.01) was observed to final weight, weight gain, specific growth rate, and final length. Survival, carcass yield, carcass without head yield, height, head length parameters no showed difference (P>0.05) in function of feeding level. Feeding level of 9.5 % of body weight is recommending to pacamã fingerlings.
