Influence of water temperature on induced reproduction by hypophysation, sex steroids concentrations and final oocyte maturation of the “curimatã-pacu” Prochilodus argenteus (Pisces: Prochilodontidae) [PDF]

open access: yes, 2011
Most fishes with commercial importance from the São Francisco basin are migratory and do not complete the reproductive cycle in lentic environments, such as hydroelectric plant reservoirs, hence natural stocks are declining and there is an urgent need to

Trends in Medicinal Uses of Edible Wild Vertebrates in Brazil

open access: yesEvidence-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

Lipid content and fatty acid dynamics of female muscle, oocytes and larvae of Prochilodus argenteus (Spix & Agassiz, 1829)

open access: yesAquaculture Reports, 2020
This work aimed to determine fatty acid dynamics and lipid composition of female muscle, oocytes, newly hatched larvae (NHL) and first feeding larvae (FFL) of Prochilodus argenteus. Oocytes and NHL had the highest percentages of total lipids.

Inferring Diversity and Evolution in Fish by Means of Integrative Molecular Cytogenetics

open access: yesThe Scientific World Journal, Volume 2015, Issue 1, 2015., 2015
Fish constitute a paraphyletic and profusely diversified group that has historically puzzled ichthyologists. Hard efforts are necessary to better understand this group, due to its extensive diversity. New species are often identified and it leads to questions about their phylogenetic aspects. Cytogenetics is becoming an important biodiversity‐detection

Combined Effects of Dietary Soybean Lecithin With Vitamin C or Inositol on Growth, Gonadal Development, and Intestinal Microbiota in Longsnout Catfish

open access: yesAquaculture Nutrition, Volume 2026, Issue 1, 2026.
To investigate the combined effects of soybean lecithin (SL) with vitamin C (VC) or inositol (INO) on growth, gonadal development, and intestinal microbiota, 2‐year‐old longsnout catfish (Leiocassis longirostris) were fed four isonitrogenous and isolipidic diets for 12 weeks, including a control diet, a 4% SL diet, a 4% SL + 0.5% VC (SC) diet, and a 4%

Influência da biomassa inicial sobre o crescimento e a produtividade de peixes em sistema de policultivo Effects of initial biomass on fish growth and fishery productivity in polyculture systems

open access: yesCiência e Agrotecnologia, 2006
Analisou-se o crescimento dos peixes, a composição das espécies e a produtividade de quatro policultivos (P75, P78, P87 e P207), visando melhorar o manejo e a produtividade pesqueira dos pequenos açudes (0,1-5,0ha) do Semi-Árido brasileiro. Simulou-se as

First Records of Length–Weight Relationships for Ten Fish Species From the Middle Stretch of the Uruguay River, Southern Brazil

open access: yesJournal of Applied Ichthyology, Volume 2026, Issue 1, 2026.
This study estimated the length–weight relationships (LWRs) of 10 fish species from the middle stretch of the Middle Uruguay River basin, aiming to provide new morphometric data and contribute to the knowledge of Neotropical ichthyofauna. Fish were collected at seven sites with sampling conducted at each site during every season, totaling 84 sampling ...
