This study evaluated short cycles of feed deprivation on the growth performance and survival of larvae and juveniles of the ornamental fish Pyrrhulina brevis. The first experiment used larvae fed with artemia nauplii in a completely randomized design arranged in factorial (2 × 5) distributed in two feeding frequencies (two or four meals a day), five feeding deprivation protocols (7/0: seven days of continuous feeding [DCF] and no feed deprivation; 6/1: six DCF and one day of feed deprivation; 5/2: five DCF and two days of feed deprivation; 4/3: four DCF and three days of feed deprivation; Alt: alternated feeding days), and five replicates. The second experiment used juveniles arranged in a completely randomized design with five treatments (same treatments from previous experiment) and five replicates feeding commercial ration. For larviculture, the feeding deprivation resulted in the worst larvae development rate and survival. The use of feeding deprivation is not recommended for larvae because it is dependent on exogenous feed daily. For juveniles, one day of feeding deprivation a week provided lower ration consumption without negative effects on fish development. |

In this study, nanoemulsions of essential oil from Ocimum gratissimum (Linn) (EO) were produced using low and high energy techniques using cashew gum (CG) as a co-surfactant. The main constituents of the EO were determined by Gas Chromatography coupled with Mass Spectrometry (GC?MS), and their presence in the EO and in the formulations verified by Fourier Transform Infrared Spectroscopy (FTIR) and UV?visible spectrophotometry was observed the encapsulation efficiency (EE%), with colloidal stability. Nuclear magnetic resonance (NMR) was used to study cashew gum. Dynamic light scattering analysis (DLS) determined the nanoemulsion Z means, polydispersity index and the Zeta potential value, nanoparticle tracking analysis (NTA) were determined. The nanostructured EO showed better antibacterial action against the pathogenic gastroenteritis species Staphylococcus aureus, Escherichia coli and Salmonella enterica when compared to free EO. Atomic Force Microscopy (AFM) was used for morphological analysis of the nanoparticle and study of the action of the nanoemulsion through images of the cellular morphology of S. enterica. The antioxidant activity was evaluated against the ABTS radical (2,2?-azino-bis diazonium salt (3-ethylbenzothiazoline-6-sulfonic acid)). The encapsulation of EO in a nanostructured system improved its antibacterial and antioxidant activity, the low energy synthesis showed greater storage stability, remaining stable for 37?days. |
