Application of a deep learning image classifier for identification of Amazonian fishes

Ecology and Evolution, Volume 13, Issue 5, May 2023., 2023
To address the growing prevalence of large ecological datasets combined with a need for rapid species identification tools, we describe a novel application of a computer vision model, which is built to rapidly identify Amazonian fishes from captured image data.

A meta‐analytic review of monoterpene for fish anaesthesia

Fish and Fisheries, Volume 24, Issue 3, Page 367-380, May 2023., 2023
Abstract The use of anaesthetic agents has been increasing to address the welfare needs of different fish species in scientific and aquaculture practices. MS‐222 is the most used synthetic anaesthetic but some limitations and side effects have been reported.

Cryogenic preservation of embryos ofProchilodus lineatus(Valenciennes, 1836) (Characiforme; Prochilodontidae) [PDF]

Zygote, 2009
SummaryWhile the freezing techniques of mammal embryos have been providing promising results, the cryopreservation of teleostean eggs and embryos have remained unsuccessful up to now. Therefore, this work aimed to develop a procedure of cryogenic preservation of embryos ofProchilodus lineatusand to observe, at both structural and ultrastructural levels,

Transmission Behavior of B Chromosomes in Prochilodus lineatus (Characiformes, Prochilodontidae).

Cytogenetic and genome research, 2016
The population of Prochilodus lineatus found in the Mogi-Guaçu River is karyotypically polymorphic, carrying acrocentric, metacentric, and submetacentric B chromosomes. The analysis of each B chromosome frequency in this species revealed a variation in the distribution pattern, with the metacentric type having the highest frequency (73.30%), followed ...

Structural and ultrastructural analysis of embryonic development ofProchilodus lineatus(Valenciennes, 1836) (Characiforme; Prochilodontidae) [PDF]

Zygote, 2006
SummaryThis survey was performed to characterize the embryogenesis ofProchilodus lineatus. Seven stages of embryo development were identified – zygote, cleavage, blastula, gastrula, segmentation, larval and hatching – after a period of incubation of 22 h (24 °C) or 14 h (28 °C).
