The use of morphometric analysis to predict the swimming efficiency of two Neotropical long-distance migratory species in fish passage

Neotropical Ichthyology
This study investigated the external body morphology (based on morphometric data) and the swimming efficiency in fish passages (based on the ascent time in a fish ladder) of two Neotropical long-distance migratory species.

Menthol and eugenol as natural anesthetics for early juveniles of curimba

Revista Brasileira de Zootecnia, 2018
The objective of this study was to evaluate menthol and eugenol as anesthetics for early juveniles of curimba, Prochilodus lineatus. Juveniles of 4.0±0.5 g and a total length of 8.8±0.1 cm were exposed to the anesthetics menthol (20, 30, 40, 50, 60, 70 ...
