Improving the Efficiency of Lambari Production and Diet Assimilation Using Integrated Aquaculture With Benthic Species [PDF]

Sustainability, 2021
A single farmed fish species assimilates about 20% of the nutrients in the supplied diet. This study evaluated if the culture of complementary ecological-function species can recover nutrients dispersed into the water and transform them into high-valued biomass. A completely randomized experiment was designed with three treatments and four replications

O lambari Astyanax altiparanae (Characidae) pode ser um dispersor de sementes?

Acta Scientiarum. Biological Sciences, 2003
This work characterized the feeding of Astyanax altiparanae in the sub-basin of Corumbataí river and in the basin of Jacaré-pepira river with a focus on the ingestion of Croton urucurana seeds. The food items of Astyanax altiparanae were, in decreasing APD (Alimentary Preference Degree) order: allochthonous insects, allochthonous plant material, Croton

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
