High-resolution numerical modelling of the barotropic tides in the Gulf of Gabes, eastern Mediterranean Sea (Tunisia)
2017
International audience; A high-resolution 2D barotropic tidal model was developed for the Gulf of Gabes and used to characterise hydrodynamic processes and tidal dynamics. The model is based on the Regional Ocean Modelling System. It is forced at the open boundaries by the semidiurnal M2 and S2 astronomical components while meteorological forcing has been neglected. The model results show good agreement with observations confirming that it reproduces the gulf's main tidal characteristics reasonably well. In fact, the simulated semidiurnal tidal components M2 and S2 generate important sea level variations and coastal currents. Tidal propagation is directed to the gulf's western sector while …
Occurrence of the lessepsian species Portunus segnis (Crustacea: Decapoda) in the Gulf of Gabes (Tunisia): First record and new information on its bi…
2015
The alien blue swimming crab, Portunus segnis (Forskal, 1775), an Indo-Pacific species has been recorded in the Southern Mediterranean Sea since decades, even if its occurrence along the Tunisian coasts was not recorded yet. This paper reports the first record of P. segnis in the Gulf of Gabes, south-eastern Tunisia, with few observations on its biology and ecology. Twenty-four females of P. segnis were accidentally caught by local fishermen in October 2014 in shallow sandy areas covered mostly by seagrass and algal beds. Among these 24 individuals, 14 specimens (58.33%) were ovigerous. The mean carapace length (CL) and width (CW) of ovigerous females were 143.0 +/- 5.8 mm and 67.8 +/- 3.6 …
