Abstract: |
We determined the
efficacy of marking the otoliths of three small-sized progenetic gobies to
validate their increments periodicity. These small gobies present high
mortalities and rearing difficulties making the direct validation difficult. The
otoliths were marked by fish immersion in a bath of alizarin red S (ALR). Fishes were euthanatized and the number of
increments in their otoliths laid down after the fluorescent mark were counted
and compared with the number of elapsed days. Results validated the daily
periodicity of Aphia minuta and Pseudaphya ferreri. The high mortality hindered the validation of
Crystallogobius linearis.
