Otoliths, calcified structures in the inner ears, are used to estimate fish age, and their shape is an efficient fish stock identification tool. Otoliths are thus very important for the management and assessment of commercial stocks.

The effect of growth rate on otolith-based discrimination of cod (Gadus morhua) ecotypes.
Otolith shape has previously been used to identify ecotypes within the Icelandic cod (Gadus morhua) stock, using DST profiles to validate the results. Fish otolith shape variation has repeatedly been found to be largely determined by growth rate.

Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Otolith shape as a tool for representing different growth in young and adult yellowfin tuna (Thunnus albacares, Bonnaterre, 1788) [PDF]
The stock status of yellowfin tuna (Thunnus albacares) (YFT) in the Indian Ocean is currently concluded overfished and is subject to overfishing. The information about the YFT population structure is fundamental for effective fisheries management and ...

Otolith shape discrimination of Liza ramada (Actinopterygii: Mugiliformes: Mugilidae) from marine and estuarine populations in Tunisia [PDF]
Background. The thinlip grey mullet, Liza ramada (Risso, 1810), is widespread in Tunisia. Despite its economic importance, the stock discrimination of this fish is poorly understood.
