Curcuma longa as additive in the diet for Astyanax aff. bimaculatus

Fish Physiology and Biochemistry, 2017
The aim of the present study was to evaluate the effect of turmeric (Curcuma longa) as additive in the diet for Astyanax aff. bimaculatus. Fish (0.83 ± 0.04 g) were fed, for 60 days, with six diets containing 0.0, 20.0, 40.0, 60.0, 80.0, and 100.0 g turmeric kg-1 feed.

Effect of timing of hormonal induction on reproductive activity in lambari (Astyanax bimaculatus)

Theriogenology, 2012
The objective was to evaluate the influence of the timing of hormonal induction, using gonadorelin or common carp pituitary extract (CPE), on the reproductive activity of female Astyanax bimaculatus. Fish (N = 44) were weighed, measured, and acclimatized to experimental conditions with a photoperiod of 12 h:12 h light:dark (L:D) for 10 days.

Enhanced flow sensing with interfacial microstructures

Biosurface and Biotribology, Volume 6, Issue 1, Page 12-19, March 2020., 2020
Biological flow receptors show astonishing performance and are used as models for the design of novel flow sensors. However, the functional importance of interfacial microstructures is seldom discussed in previous review papers. Herein, this review summarises the underlying biomechanical principles in the biological flow receptors and describes the ...

Effect of photoperiod stress assessment and locomotor activity of female lambari (Astyanax bimaculatu) [PDF]

Ciência e Agrotecnologia, 2014
Some studies and scientific investments have been done in aquaculture aiming to minimize the stress of the fish due to different factors, as management, nutritional status, water quality, temperature, photoperiod, and salinity. This study aimed to verify the effect of photoperiod on locomotor activity and plasma levels of cortisol and glucose in female
