Introduction

I hold an Associate Professor position in the Department of Biological Sciences at the University of Tunis El Manar (Faculty of Sciences of Tunis) where I’m in charge of a number of courses: Biostatistics, Applied Statistics and Probability, Linear Geo-statistics, Biomathematics and Quantitative Genetics. In addition to the teaching tasks, I supervise PhD theses and masters'. I received my B.S. in Animal Biology from the University Cadi Ayyad of Marrakech (Faculty of Sciences Semlalia) of Morocco, and a M.S. (in Animal Ecology), a Doctorate Degree (in Theoretical and Applied Genetics) a Ph.D. degree (Theoretical Biology) and an Habilitation To Supervise Research from the University of Tunis El Manar (Faculty of Sciences of Tunis) in Tunisia.

Otolith shape analysis as a tool for stock discrimination of Liza aurata from two Tunisian lagoons (Boughrara and El Biban)

Cahiers de Biologie Marine (60)

Abstract: The golden grey mullet Liza aurata (Risso, 1810) is one of the most common mugilid species in Tunisia. The

aim of this study was to investigate, for the first time, the stock discrimination of this species for two Tunisian populations

based on sagittae shape, using different statistical analyses. The specimens were collected during three months from two

lagoons’ stations in southern of Tunisia: El Biban and Boughrara. In total, 120 fish were sampled from the two sites, 60 fish

from each lagoon (30 males and 30 females), and included for different statistical analyses. The Discriminant Function

Analysis (DFA) for otolith shape showed statistically significant difference between specimens of the two lagoons’ stations.

In addition, the results revealed distinct differences in otolith shape between the two populations and left-right symmetry

of otolith in both sexes of each of the two stations, except one male from Boughrara which showed an asymmetry in the

shape of the otolith. Moreover, sexual dimorphism was observed only in the left side of the otolith of El Biban specimens.

The shape variability between specimens of the two lagoons’ stations is probably correlated with local environmental and

ecological factors.

Local variability in the sagittae otolith shape of Mugil cephalus from the Sea of Tabarka and the dam of Nabeul in Tunisia

Research & Reviews: Journal of Zoological Sciences 5 (2): 68-79.

Research & Reviews: Journal of Zoological Sciences

The otolith shape analysis is a powerful tool to use in studies focusing to marine biology and ecology in various aquatic areas (marine, dam and lagoons) as well the identification of fish stocks of species. In the present study, the sagittae otoliths were used to compare specimens of Mugil cephalus collected from two Tunisian regions, Tabarka Sea and Nebeur Dam. We analyzed the shape variation by sex (male and female) and otolith side (left and right) in order to discriminate the stock structure of Mugil cephalus. Discriminant analysis demonstrated statistical differences in the otolith shape between specimens of two sampling sites, which indicate a clear population differentiation. Also, these results were confirmed by highly statistically significant difference between otoliths’ shape (left and right) for both sexes. Hence, the shape variability of otolith between these two sampling sites is probably correlated with local environmental factors.
