Tipo de desova e fecundidade de Moenkhausia intermedia (Eigenmann, 1908), na represa de Ibitinga, Estado de São Paulo, Brasil [PDF]

Brazilian Journal of Veterinary Research and Animal Science, 1991
Foram determinados o tipo de desova e a fecundidade de Moenkhausia intermedia na Represa de Ibitinga, Estado de São Paulo (210 46'S-480 59'W), no período de junho de 1989 a maio de 1990. Utilizaram-se 37 fêmeas maduras para o estudo de fecundidade, de que resultaram, em média, 6092 ovócitos. 584 fêmeas prestaram-se à determinação do tipo de desova, que

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Fresh vs. Preserved Specimens: Length‐Weight Relationships of Fishes from the Western Amazon (Napo Basin, Ecuador)

Journal of Applied Ichthyology, Volume 2024, Issue 1, 2024.
Length‐weight relationship (LWR) studies are important for fish taxonomical analysis, ecological assessments, management, and conservation practices. Although LWR studies can use measurements of either fresh or preserved specimens, few studies have directly compared these methods. This study analyzed the effect of preservation on LWR of ten small‐sized
