Otolith eco-morphological patterns of benthic fishes from the coast of Valencia (Spain)

Benthic fishes exhibit different adaptive strategies and different degrees of association with the substrate. The aim of this study is to describe the morphologic and morphometric characteristic of otolith of four species of benthonic fish off the coast of Valencia and study the relationship between...

The aim of this study is to describe the morphologic and morphometric characteristic of otolith of four species of benthonic fish off the coast of Valencia and study the relationship between these otolith's characteristics witch the substrate. The sagittae analysed belonged to the following species: Scorpaena scrofa Linnaeus, 1758 (N=40), Mullus surmuletus Linnaeus, 1758 (N=29), Uranoscopus scaber Linnaeus, 1758 (N=24) and Synaptura lusitanica Capello, 1868 (N=121). The fishes were sexed, the total length (TL) was measured in mm, and the sagittae were removed to examine their morphology and morphometry. The E (=maximum width of the otolith (OW)/ maximum length of the otolith (OL)%) and S (sulcus area (SS)/otolith area (OS) %) index were calculated. The E morphometric index showed a tendency towards an elongated or circular shape and the S index showed a tendency of macula nervous to have a greater surface area of information uptake to transmit to the fish brain. The analysis of otolith morphology and morphometry revealed the existence of different eco-morphological patterns associated with habitat use and the type of substrate where the fish is most frequently found.
