The study of the reproductive biology of Triportheus trifurcatus of the middle rio Araguaia was carried out using 275 specimens obtained in seven collections conducted in the period between November 2003 and January 2005. Females prevailed among the classes of intermediate length, as well as in the total number of samples. On the other hand, males prevailed in the smaller classes. The average length of females was larger than that of males. Four stages of gonadal maturation were macro- and…

Reproductive strategies of two Curimatidae species in a Mogi Guacu impoundment, upper Parana River basin, Sao Paulo, Brazil
TLDR
The findings provide important information to subsidize management plans for these curimatid species and indicate that species with different reproductive strategies also respond differently to environmental impacts.
Downstream effects of a large reservoir on the reproductive activity of Prochilodus hartii (Pisces: Prochilodontidae).
Reproductive strategy of Psectrogaster rhomboides Eigenmann & Eigenmann, 1889, a freshwater fish from Northeastern Brazil
TLDR
Gonadosomatic index and the condition factor were negatively correlated during the gonadal development cycle of this species, providing a population increase and exploitation of the environmental resources during the rainy period.
Reproduction of fishes of the Verde River, upper Paraná River Basin, Brazil
Abstract. Introduction: Understanding the various aspects of the reproductive biology of fish is a key step towards applying effective strategies for sustainable management of fishery resources.
Species-level ichthyoplankton dynamics for 97 fishes in two major river basins of the Amazon using quantitative metabarcoding.
TLDR
The results are discussed in the light of the main anthropogenic threats to fishes, hydropower dam construction and the Hidrovía Amazónica, and should serve as a pre-impact baseline.
Erratum to: Population regulation in a Neotropical seasonal wetland fish
TLDR
It is shown that population dynamics of Jewel tetra are influenced by the seasonal drought, which affects the various life stages of the cohort in different ways and causes changes in population size structure and extinction of local populations, which will affect recruitment in the following year.
Biologia reprodutiva de Astyanax henseli (Teleostei, Characidae) do curso superior do Rio dos Sinos, RS, Brasil
TLDR
Fatores bioticos como o indice de replecao estomacal (IR) e indice hepatossomatico (IHS), tambem nao mostraram correlacao estatisticamente significativa com o IGS, enquanto that os baixos valores de IHS durante do pico reprodutivo sugerem um maior gasto das reservas hepaticas neste periodo.

TLDR
The studied species presented evident segregation in several levels of the different available resources in the environment and the differences found in the feeding may reflect the differences in the food availability in the microhabitats used by the species.
