Morfologia e desenvolvimento do núcleo vitelínico do lambari Astyanax bimaculatus (Linnaeus, 1758) (Osteichthyes, Characidae) [PDF]
Revista Brasileira de Zoologia, 1990 A morphological study of the yolk nucleus in previtellogenic oocytes from A. bimacularus has been carried out. Six phases of development were described from its formation closed to the oocyte nucleus to its dispersion in the periferic ooplasm. Histochemical techniques indicate proteins, lipids and RNA in the yolk nucleus of A.

Insect meals in fish nutrition
Reviews in Aquaculture, Volume 11, Issue 4, Page 1080-1103, November 2019., 2019 Abstract Different studies have shown that insect meals can partially or completely replace the fish and soya bean meals that are commonly used in aquaculture. However, information is lacking on the amino acid and fatty acid contents and digestibility of different insect meals. Moreover, we evaluated different proportions of insect diets and determined

Isozymes of malate-and lactate dehydrogenase of Astyanax bimaculatus as biomarkers of environmental impact [PDF]
Ambiente e Agua - An Interdisciplinary Journal of Applied Science, 2019 The activity of certain isozymes may serve as biomarkers of specific physiological conditions of living organisms. The present work aimed to evaluate malate dehydrogenase (MDH) and lactate dehydrogenase (LDH) isozymes from the hepatic, branchial and renal tissues of the fish Astyanax bimaculatus as biochemical markers of environmental changes in the ...

Trends in Medicinal Uses of Edible Wild Vertebrates in Brazil
Evidence-Based Complementary and Alternative Medicine, Volume 2017, Issue 1, 2017., 2017 The use of food medicines is a widespread practice worldwide. In Brazil, such use is often associated with wild animals, mostly focusing on vertebrate species. Here we assessed taxonomic and ecological trends in traditional uses of wild edible vertebrates in the country, through an extensive ethnobiological database analysis. Our results showed that at

Environmental DNA, Volume 6, Issue 6, November–December 2024.We introduce the metabarcoding gap visualization and demonstrated how it can make comparisons of PCR primers rapidly comprehensible for researchers in the molecular ecology community. We use gap visualization to simultaneously interrogate multiple primer pairs and enhance reference data quality. This has significant impact for study design as selecting

Ichthyofauna Used in Traditional Medicine in Brazil
Evidence-Based Complementary and Alternative Medicine, Volume 2012, Issue 1, 2012., 2012 Fish represent the group of vertebrates with the largest number of species and the largest geographic distribution; they are also used in different ways by modern civilizations. The goal of this study was to compile the current knowledge on the use of ichthyofauna in zootherapeutic practices in Brazil, including ecological and conservational commentary
