The effect of rearing temperature in larval development of pejerrey, Odontesthes bonariensis: morphological indicators of development

Neotropical Ichthyology
It is well known that in pejerrey water temperature not only affects growth rates but also directs the sexual differentiation process. This fact rise the question of how different the development of pejerrey larvae of the same age is when reared at ...
