Morphology and morphometric relationships for sagitta otoliths in Lutjanus argentiventris (Pisces: Lutjanidae) and Hyporthodus acanthistius (Pisces: Serranidae) from the Colombian Pacific Ocean
Fish earstones, or otoliths, are inner ear structures that can be studied to determine a fish’s age and are a source of taxonomically informative data. In the present work, sagitta otoliths of the Yellowtail snapper (Lutjanus argentiventris) and the Red grouper (Hyporthodus acanthistius) were col...

| description | Fish earstones, or otoliths, are inner ear structures that can be studied to
determine a fish’s age and are a source of taxonomically informative data.
In the present work, sagitta otoliths of the Yellowtail snapper (Lutjanus
argentiventris) and the Red grouper (Hyporthodus acanthistius) were collected
in the Colombian Pacific, and their key morphological features were studied.
Otoliths of the Yellowtail snapper were distinctly concave by their distal
surface, revealing features shared with species of its genus (Lutjanus). Red
grouper otoliths were elliptic and compressed laterally by their proximal
surface, bearing similarities to those of other Serranid species. Morphometric
relationships between otolith size weight and whole fish size and weight were
also studied. In Red groupers significant statistical morphometric relationships
between otolith and body features were found via power regression models;
successfully relating otolith length with total fish length, otolith weight with
total fish length, otolith length with total fish weight, and otolith weight with
total fish weight. No significant morphometric relationships were found for the
Yellow snapper data. In both fish species, otolith transversal sections proved
best to identify its internal features and to distinguish otolith growth rings, as
a method for determining the specimen’s age. |
