“…Despite the feeding interruptions at certain intervals of the experiment, the zootechnical performance of the fingerlings was considered optimal, having a feed conversion value of 0.95 for treatment T4 (800 fish m -3 ), and an SR of 87.5%. This result was superior to that of recent studies, such as that of Brol et al (2017), who cultured tilapia fingerlings using BFT and obtained a feed conversion rate (FCR) of between 1.21 and 1.29 and SR of between 72% and 87%; and Schwarz et al (2016), who tested different tilapia fingerling densities (mean initial weight of 4.68 g) in five treatments (n = 540) for 60 days, with an SWR and 35% crude protein feed, and obtained an FCR of between 1.56 and 1.78 and an SR of between 92% and 94%.…”

The effect of producing and culturing Nile tilapia (Oreochromis niloticus) fingerlings in biofloc technology (BFT)-based systems was investigated in terms of zootechnical performance, aiming to define the best culturing density for 64 days. A completely randomized design was used, with four replications totaling 24 experimental units. The weight gain of each batch of animals per experimental unit (E.U.) was evaluated at densities of 200, 400, 600, 800, and 1,000 fingerlings m-3. For controls, a Water Recirculation System with 248 fingerlings m-3 was used. The fingerlings were fed commercial feed containing 35% protein and brown sugar as a carbohydrate source at a C:N ratio of 20:1. Dissolved oxygen, total ammonia nitrogen, pH, and temperature were monitored daily, and nitrite and alkalinity were monitored weekly. The analysis of weight gain data obtained a linear function y =-0.0017X 2 + 3.724X-87.77, with r 2 = 0.864, coefficient of variation = 14.23%, and correlation coefficient = 0.91. At the end of the cultivation period the system's planktonic community presented high diversity, dominated by rotifers and diatoms. The data of survival, density management demand, and physicochemical parameters variations of the water suggested an optimal density of 800 fish m-3 , since this resulted in an average weight gain per E.U. of 1,891.25 ± 151.24 g, with a productive efficiency index of 274.96 that is approximately three times that of the control treatment (87.43). Biofloc technology can be employed in two-phase super-intensive Nile tilapia culture systems, with a stocking density in the rearing stage of 800 fish m-3 .

“…Although pollen contributed to beneficial morphometric changes in the intestinal mucosa and liver morphology, pollen did not contribute to improvement on FCR. This phenomenon was also observed in other additives studies such as Bacillus subtilis and MOS (Carvalho et al, ), Saccharomyces cerevisiae (Schwarz et al, ) and a commercial algae‐based product (Garcia, Abimorad, Schalch, Onaka, & Fonseca, ). One hypothesis is that a long‐term dietary pollen supplementation might affect the FCR and improve the production performance.…”

Dietary bee pollen affects hepatic–intestinal histomorphometry of Nile tilapia fingerlings

et al. 2019

The bee pollen is considered an excellent source of flavonoids, carotenoids, phenolic compounds, sterols and minerals; and possesses the ability to boost the immune system, antioxidant action and other interesting therapeutic effects. This study was carried out aiming to evaluate the inclusion of bee pollen in extruded commercial diets of Nile tilapia fingerlings and its effects on the hepatic‐intestinal histomorphometry and zootechnical performance. A total of 225 tilapia fingerlings (1.25 ± 0.05 g) were distributed in a completely randomized design in 15 tanks (30 L) maintained in a recirculation water system with three treatments (0% or control, 1.5% and 2.5% of bee pollen inclusion) and five replicates. Feeding rates were defined from the weekly biometrics and periodic monitoring of the physical–chemical water quality parameters. The water quality variables remained within the appropriate range for the species throughout the experiment. There was no significant difference for the somatic indexes and zootechnical parameters in this experiment. However, the inclusion of bee pollen in Nile tilapia fingerlings diets showed a linear increase in hepatocyte morphology (p = .0098). For the intestinal variables of villus height a significant linear increase was observed (p < .05) as the pollen inclusion increased. In fish that received 2.5%, the number of goblet cells was significantly higher (p < .001) than control group and 1.5%. In this sense, the inclusion up to 2.5% bee pollen in extruded commercial diets of Nile tilapia fingerlings had a positive impact on hepato‐intestinal histomorphometry without causing negative effects on the zootechnical performance.

“…Uma das alternativas ao uso dos antibióticos, parece ser a utilização de probióticos e prebióticos na nutrição dos peixes conforme estudos realizados por Schwarz, et al (2016), Azevedo et al, (2016; Andrade e Azevedo (2018) ao concluírem o efeito destes na resposta imune e na integridade das vilosidades intestinais, além da melhora nos índices de desempenho zootécnico em alevinos.…”
