Characterization of undifferentiated spermatogonia and the spermatogonial niche in the lambari fish Astyanax altiparanae

Theriogenology, 2017
Undifferentiated type A spermatogonia are the foundation of fish spermatogenesis. This cell population includes the spermatogonial stem cell population, which is able to either self-renew or differentiate into cells that will generate the male gamete - the spermatozoa. Spermatogonia stem cells are located in a specific region of the testes known as the

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.

Sublethal Effects of Propiconazole On The Metabolism of Lambari Deuterodon Iguape (Eigenmann 1907), A Native Species From Brazil

Fish Physiology and Biochemistry, 2021
Abstract The objective of this study was to analyze the sublethal effects of propiconazole on Deuterodon iguape a native fish common in Brazil, which has potential for aquaculture and use as a bioindicator. The hypothesis was to test whether D. iguape has a metabolism similar to Danio rerio so that its use in bioassays may be validated.
