文摘
- •
We investigated Invasive brown trout populations in sub-antarctic Kerguelen Islands.
- •
We used mark-recapture technic on Alizarin Red S marked otoliths.
- •
We validated annual formation of annuli in Kerguelen low-latitude environment.
- •
We propose a new method to select an optimal otolith's zone for data transects.
- •
This zone facilitates concomitant analysis of chronological series and age data.
